Manchesters United's new Sweeper plays a good clean game.

Manchester United Football Club (MUFC) has a new sweeper, but this particular new signing will never kick a ball. Instead, two brand new Scarab sweepers supplied to Trafford Council by TransLinc will keep the Old Trafford Stadium spick and span.

As experts in supplying highly tailored local authority vehicles, TransLinc has provided Trafford Council with a fleet of 14 road sweepers. Two Scarab units have made the grade, one in full Manchester United livery, to keep the Old Trafford area clean on match days.

The stadium has specific operational requirements and TransLinc was tasked to source units capable of cleaning around and under the stadium, as well as the car park and streets in the surrounding area. The Scarab Merlin XP 7.5 tonne street sweeper was the obvious choice to keep the streets around Old Trafford clean, while the Scarab Minor Compact Urban/Precinct ticked all the right boxes for cleaning around the stadium, thanks to its vast array of specialist equipment.

Equipped with a unique sweeping brush configuration, a powerful four metre long wander hose, high pressure water jet and side access doors for the loading of bulky waste items, the versatile sweeper will ably cope with the specialised heavy duty cleaning requirements of one of the UK’s foremost sporting venues.

The sweeper is an essential part of the Manchester United team, making an appearance at every home game. It is in operation for up to four hours during each match, clearing up debris left by the 78,000 spectators visiting the ground. On average the unit will clear five tonnes of rubbish on each outing.

George Johnstone, Group Property Manager of Manchester United says, “It’s our responsibility to ensure the Stadium and its surroundings are a safe and welcoming environment for our staff, players, supporters and visitors. This includes removing any dirt or debris that could be a potential health or safety hazard. We are grateful to Trafford Council and TransLinc for providing us with machines that perform this task thoroughly and efficiently.”

TransLinc’s Regional Sales Manager, Rob Hobson said, “Due to Manchester United’s specific cleaning requirements, TransLinc was tasked, by Trafford Council, to source units capable of covering all eventualities both inside and outside the stadium. Working closely with suppliers such as Scarab ensures we have the correct vehicle on hand to meet these needs.”

Vic Beckwith, Sales and Marketing Manager, Scarab said, “We were well aware that a venue like Old Trafford Stadium requires different cleaning approaches for individual areas. The Scarab Merlin XP sweeper was perfect for sweeping the streets around the stadium and the Scarab Minor sweeper was chosen because it copes with varied cleaning in more confined areas, like the seated stands.”

Scarab Merlin XP - Test Drive
Wednesday - Oct 17, 2007 9:15 am
Street Cleaning is an essential part of any council`s environmental concerns. But, whether the local authority takes on the work itself, or a contractor assumes responsibility for sweeping, choosing the right machine for the job can be a complex decision.

Having an auxiliary, or donkey, engine means that the sweeper brush is run on reduced-tax red diesel, with just the truck chassis being moved by expensive DERV.
Yet there are those who would say that running the hydraulics from the truck`s own engine does not add as much to fuel consumption as the second engine will use. As an environmental aside, there also seems little point in specifying the latest Euro 4 engine in the chassis, if the secondary engine does not have to conform to that standard as well.
But there remains demand for both systems, as evidenced by the fact that even Scarab - a long time supporter of the single engine truck - now offers a twin-engined sweeper to those who want one, although that is primarily for overseas markets. Scarab`s main interest remains in the single-engine market, with the Merlin XP its latest 7.5 tonne model. The Merlin XP has been designed specifically for the requirements of the Euro 4 trucks on which it will be built. And LAWR caught up with one working for the London Borough of Sutton, to the south of the capital.

As mentioned, the Merlin XP was designed around Euro 4 chassis requirements, taking into account the additional weight that they will carry to cope with achieving emissions regulations. This includes AdBlue tanks and other added technology that can result in a weight rise of up to 60-100kg over Euro 3 models of the same truck. While this sort of weight increase can be largely ignored on a heavier model, on a weight conscious 7.5 tonne vehicle it becomes an important consideration.

MAKING LIGHT WORK OF THE DESIGN
To combat this, Scarab`s designers and engineers went back to the drawing board and created a body that is up to 300kg lighter than its previous 7.5 tonne sweeper, offering at least 550kg more payload than some competitors. The XP in the title means just that: eXtra Payload. On an Iveco or Daf 7.5 tonne chassis, Scarab claims that the Merlin XP with a single sweeper has a a potential payload of 2,325kg, while the more popular dual sweep truck can carry 2,115kg.
This weight cut has been achieved by reducing the height of the body, the resulting loss of metal making up the bulk of the weight saving. But the truck retains a competitive 900 litre water tank at the front of the body and the hopper has a healthy 5.5m3 gross capacity, down from 6.2m3. That means a hopper payload volume of 4.7m3, which is certainly competitive against a twin-engined truck.

As with all of the Scarab`s Merlin trucks, the XP uses the firms proven hydrostatic drivetrain, which is fitted in the chassis between the regular truck gearbox and the back axle. This transmission design allows the sweeper to be driven to the work site as a conventional truck, with all of the fuel consumption benefits of the latest Euro 4 designs. When ready to sweep, the driver simply engages top gear in the regular gearbox and switches on the hydrostatic transmission.
In hydrostatic mode, the operator controls forward and reverse direction by the use of a simple lever next to the driver`s door, which is perfect for those who prefer to sweep with a head out of the window.
The truck`s throttle pesal determines the travel speed. At the same time, the gearbox drives the hydrostatic pumps to power the suction fan and brush system, providing protection from abuse for both the truck`s driveline and the sweeper attachment.
The hydrostatic transmission provides travel speeds of 0-20mph and Scarab claims that the truck can tackle the steepest of gradients without losing power to the sweeper or suction operation. That suction system uses a 900mm diameter fan mounted in the top of the hopper, providing a virtually straight through flow of air from the suction nozzles.

NOZZLE CONTROL
The nozzles themselves are 750mm wide with a 250mm diameter suction hose. Four manually adjustable water spray jets are fitted to the nozzles at 90° intervals to provide internal dust supression. An optional four-jet water boost bar can also be fitted in front of the suction hose for use in extreme conditions. The central wide sweep brush is a 320mm diameter design with direct hydrostatic drive. The brush is fully floating with shock absorbers to prevent bounce. Three-speed control is standard and customers can add a brush pressure control if desired.

The suction nozzle, side brush and wide sweep brush can be raised or lowered independently . This provides a variety of sweeping options: from a 740mm wide suction nozzle only;through a 1,060mm suction nozzle and side brush; a 2,000mm wide suction nozzle, side brush and widesweep; or the full 2,950mm width using both nozzles, both side brushes and the wide sweep central brush.

The Merlin XP also comes with a lightweight 4m long wander hose with a 150mm diameter nozzle, for cleaning gullies and akward areas. Quick release wander hose points are located on either side of the body`s rear door. All of Scarab`s sweeping and suction systems are controlled by a sturdy CANbus panel in the cab.

The panel controls the suction, fan, brushes, hopper, work lights and water sprays. However there is a secondary set of controls on the chassis for tipping the hopper, allowing closer inspection of the tipping area for drivers. The CANbus panel also displays operating data, including fan speeds, distance and hours swept information, and can be used for system diagnosis in the event of a fault.

The Scarab Merlin XP successfully answers all the questions asked by the latest emissions legislation. With chassis becoming heavier, to cope with with AdBlue tanks and other exhaust after treatment, Scarab has managed to reduce the weight of its sweeper equipment to keep payload for the operator high. Certainly there has been a reduction in the hopper volume, but this has been more than offset by the payload advantage, and the truck will be able to work for a lot longer with the slightly smaller hopper than it would with virtually no payload capability.

As Euro 4 trucks become the norm, an increasing number of local authorities and contractors are going to be looking to maximise the use of their vehicles. If they decide to stay at 7.5 tonnes , Scarab`s Merlin XP offers a solution to meet their needs.

Merlin is Man Enough for Sutton

The London Borough of Sutton runs four Scarab Merlin XP sweepers in a long term contract hire agreement with vehicle specialist London Hire. London Hire`s contract rental agreement covers all of the Borough`s vehicle needs, except refuse collection vehicles. The five year rolling contract, which began 18 months ago, replaced around 70 cars, mini buses, light commercial vehicles and sweeper trucks that were either owned by, or leased by the Borough.

In a co-operative twist, London Hire sub-contracts the maintenance of the vehicles back to the borough`s garages. In the case of the sweepers, that only covers the chassis because Scarab has a seperate maintenance agreement with the borough for the brush equipment.

Sutton has 78,000 households with a population of around 180,000 people. The borough`s working area covers more than 400km of roadway, enough to keep three Merlins busy six days a week.

"We do try to get down every road within two weeks," says fleet services manager Matt Club. However, town centre streets are all swept every day. To ensure that the oprtation meets this demand, he operates three Merlin XPs and keeps a fourth machine as a spare. "To ensure service continuity we have dedicated spares on site," he adds.

The borough has some other sweepers that are soon to be replaced by smaller Scarab Minors. Indeed it was the strength of the Minor design that first led the borough to Scarab.

"We have got some Schmidt Swingos and they are sometimes not robust enough," explains Club. "We tried the Minor first, and then went for the Merlin. The reason we need Minors is to clean precincts. Whenever we got replacements in before they tended to be Scarabs and we found that the machine is right for the job. The Merlin is more than man enough for street work."

Given their age, Sutton`s Merlin XPs are equipped with Euro 3 engines, providing even more payload for the sweeper. However London Hire has been so pleased with the Merlins performance, that it has recently ordered an additional four Scarab Merlin XP trucks on Iveco Cargo chassis, with the Euro 4 engine, to complement the fleet.

Mistral Prototype Review
Thursday - Sep 13, 2007 5:24 am

On the face of it, the announcement that Scarab Sweepers was to introduce a new, auxiliary-engined, truck-mounted sweeper was something of a shock - perhaps akin to discovering that the Americans had, after all, decided that soccer was superior to American football, or that the French were abandoning boules in favour of cricket.
Surely, the whole thrust of Scarab marketing over the past two decades has been to insist that a single power unit - the one powering the truck itself - was more than sufficient, when coupled with a hydrostatic pump/transmission unit, to power the sweep systems.

Indeed, it could be argued that Scarab's success in world markets has been based almost entirely on this assertion. The company has undergone dramatic and constant expansion over the past two decades, to the point where it is now a major player in the domestic UK market, as well as a regular supplier of machines to Europe (France in particular), the former Eastern Bloc countries, Russia, Australia, New Zealand and other Pacific Rim markets. Of course, most compact sweepers today have hydrostatic transmission, but the purpose-built Scarab Minor has continued to sell well round the world, in spite of competition from a number of other manufacturers. Originally designed to replace the East German-built Multicar chassis, Scarab initially produced its own chassis/cab unit with a Ford engine, then a VW and - more recently and most successfully - with a compact 2.8 litre VM turbo diesel, producing 59 kW.
All Scarab Minors are hydrostatic but, in the larger truck-mounted, sector, Scarab was still in a minority, as auxiliary-engined designs remain the most common solution.
According to marketing manager Vic Beckwith, the ever-increasing demand for Scarab products has resulted in some logistical problems, particularly when it comes to the larger single-engined, truck-mounted sweepers. These require a hydrostatic package engineered into each specific truck chassis. 'The problem is that a different mounting assembly is needed for each make of truck chassis. We could, of course, bring each truck chassis into our factory in the UK for hydrostatic installation and bodying, but this is hardly practical on a large scale, or for more distant world markets, 'he explains. 'While we have set up local production facilities for single-engined, truck-mounted, hydrostatic sweepers in countries such as Australia, this solution is not always practical.

Increasing Demand

According to marketing manager Vic Beckwith, the ever increasing demand for Scarab products has resulted in some logistical problems, particularly when it comes to the larger single-enginAnother approach was required, especially as, in many previously strong markets for Scarab truck-mounted sweepers, operational changes were jeopardizing the purchase of completed units from the UK. Vic Beckwith explains: 'where open-trade agreements between the UK and other countries like Australia are in place, import tariffs have not been a barrier. But in countries where sweepers were previously purchased by government departments without import duties being incurred, today the situation has radically changed. In many cases, previously commercial contractors have replaced government-run departments. In such cases, the duty exclusions enjoyed by the government department do not continue to apply to their contractors, and with import duties running at up to 60% in some countries, this can make our equipment prohibitively expensive. 'A continuing stream of enquiries suggested the need for a long-term solution. While contending that a full hydrostatic package was the most environmentally acceptable configuration for a truck-mounted sweeper, Scarab design engineers did at least have the satisfaction of noting that, in terms of durability, reliability and everyday operating efficiency, all the other standard components that go to make up the Scarab Merlin and Scarab Magnum hydrostatic truck-mounted machines had achieved an excellent reputation in their own right. Indeed, hadn't the introduction of the gearbox PTO-driven Unidrive option on the truck-mounted ranges - originally produced for the tough, price-sensitive, UK highway-resurfacing contractor market - already made the point that Scarab machines need not always be fully hydrostatic?

No performance shortfall

Unlike the Scarab Merlin and Magnum hydrostatic machines, it was necessary to select first - or sometimes second - gear, when in sweep mode, and then start the second engine. This served to remind me how much more driver-friendly the infinitely variable Scarab hydrostatic system is when trying to match travel speed with changes in litter density. When it was necessary to stop and reverse back to clean out heavily soiled areas, reverse gear had to be selected manually, rather than with the simple forward/reverse control on fully hydrostatic Scarab machines. At least the sweeping brushes were still raised automatically when reverse gear was selected. In all other respects, the sweeping performance was indistinguishable from that of other well-established Scarab products.

Obviously, when stationary, the noise of the VM auxiliary engine mounted behind the truck cab was noticeable at start-up. Scarab uses a larger diameter suction fan than many comparable competitors and this is retained on the Mistral design, as is the option of a 5.5, 6.5, or 7.5 m3 hopper assembly. Water for the dust-spray suppression system comes from a separate 1300-litre water tank mounted ahead of the auxiliary power unit. And in all other respects - aside from the need to start and stop the auxiliary engine - the controls and features are familiar from other Scarab models. The big question is: did the presence of the auxiliary engine compromise the efficiency or power of the sweep systems? After running over surfaces covered in a carpet of wet, fallen leaves and other debris from several stormy days, I have to say that the answer is 'no'. Was there an unacceptable increase in either in-cab or exterior noise? Factory tests concluded 'not significantly', but I wanted to compare the Mistral with several other new hydrostatic machines undergoing tests round the factory. My experience was not conclusive: there is more start-up noise - indeed, as previous Scarab marketing material has pointed out, a single engine produces lower emission rates for both noise and exhaust pollution. But when sweeping, the extra noise in the cab was not as significant as I had expected, having driven a number of other auxiliary engined sweeper designs on other occasions. Why was this? Design engineer Andy Duncan provided the answer: 'We've used the same VM engine as we use on our Minor,' he explained. 'This has enabled us to use the same fluid-drive system to power the sweep systems. As well as being well proven and efficient, it enables us to get rid of the need for various drive belts, pulleys and gearbox angle-drives used by our competitors. It is simpler to manufacture and assemble, more likely to be reliable in service in harsh environments and, above all, we are sure it helps cut down on both noise and vibration'. The only minor level of vibration discernible during my test was finally pinned down as coming from the truck, rather than the sweeper installation - although Andy Duncan added that noise suppression equipment would offer additional refinements on production machines.

Conclusions

What started out as a project aimed at enabling Scarab Sweepers to compete more widely on world markets, has ended up as a clever amalgamation of advanced production procedures and simple common sense. The new Mistral product line is not, as might be expected, a 'me too' copy of existing competitors' auxiliary-engined truck sweeper designs. Instead, it is a fresh look at the problem of getting an efficient, modern sweeper design out into developing markets. By combining new technology with a high content of existing, well proven components from other production machines. Scarab has come up with a machine that is bound to blow new life into the sweeper market.

Scarab Magnum - Test Drive
Friday - Jul 14, 2006 9:19 am

Scarab, of course, pioneered the single-engine sweeper which uses the vehicle engine to power its suction fan and brushes via hydraulic drive. The absence of the auxiliary engine, its fuel tank and cooling system used on all other sweepers in Ireland means more than one tonne more pay-load and a bigger hopper.The advantages of having only one engine are obvious, but until Scarab came along some 20 years ago the problem had been how to keep the lorry engine running at sufficient rpm to power the suction fan and brushes, while keeping road speed down when moving - yet still retaining normal travel speeds.

The solution was twofold. First came the remarkable increase in engine power outputs, so a relatively small truck had the neccessary 50 to 60 bhp in reserve to power the sweeping services as well as moving along the road. The second development was hydrostatic drive, achieved by fitting a hydraulic pump to the engine and a motor on the drive shaft. While sweeping the Scarab becomes an automatic, with forward-reverse shuttle lever and speed from 0-30km/h controlled by the accelerator. For travel, the Scarab hydrostatic drive is disengaged and the vehicle is driven in the normal manner.
While most contractors now accept hydrostatic drive, as fitted to telescopic handlers, fork trucks, dozers and most compact sweepers, the fact remains that it does cost more. So five years ago Scarab came up with Unidrive, which is based on a 13t to 19t chassis with normal gearbox and fitted with a camshaft-driven hydraulic pump to drive the sweeping services. It competes head to head on price with the twin-engined sweeper, which also rely on the normal chassis gearbox for sweep speed control.
The demonstrator Magnum on a DAF LF55 chassis made its Northern Ireland debut at IWM Newcastle in April, and I was able to try it next day.
It`s an impressive machine when opened up, with a 6.5m3 payload volume in its stainless steel hopper and an 1800 litre water tank against the 1250 litre of a typical twin-engined sweeper which looses hopper space to accommodates its auxiliary engine and fuel tank - not to mention loosing an extra tonne of payload.

Unidrive components are the same as those on the hydrostatic machine, as are features such as steel pipes to replace rubber hoses, manual over-ride on control valves and steel rather than cast suction nozzle boxes. I liked the automatic fan wash which comes with the optional high pressure lance, otherwise it`s fairly easy access above the tailgate.

Some machines induce dislike from first acquaintance, some improve with experience, a few feel just right. For me the Magnum falls into the third category, due to the brilliant DAF LF chassis. Any driver will love the DAF for its low noise, smoothness and cab comforts, while its nine-speed gearbox, light controls and excellent lock make it an ideal basis for sweepers.

"Just use crawler gear and take your time", said demonstrator Tony Lawrence, "and you`ll find it`s easy". And he was right.
The cruise control is used to set engine speed to about 1000 rpm. Switching on the fan and imposing its 45 bhp load makes no difference to engine speed or noise, such are the wonders of electronic diesel control. With 180 bhp available the DAF isn`t even trying, and letting out the clutch in crawler gear produces effortless progress at 1.6 mph.
With both side brushes and centre brush extended the Magnum swept a 3.2m path around a long neglected car park with many loose stones. The surface was left spotless, leaving only a light stain where cement powder had been scatterd on oil spillages. Even this disapeared when the optional high-pressure front water jets were selected, the powerful suction leaving the surface almost dry. On lighter work the machine will sweep happily in fourth gear and full width.
The wander hose is equally impressive, bricks and rocks being lifted from several inches away and light material from up to a metre. In fact the suction is so strong that the fan speed must be reduced slightly to prevent the hose locking onto the ground.

Like most people, I expected a cost advantage from using red diesel for an auxiliary engine rather than the all too expensive white required by the motive power. But because the Scarab has only one engine working in its most efficient torque band it uses less fuel than a twin-engined sweeper with one idling and its auxiliary working hard, doubling friction and thermal losses. In fact the Scarab uses as much as one-third less, according to tests carried out by the Paris municipality.
Mr Lawrence says the Magnum is hard pressed to use eight litres per hour on the heaviest work, which compares with up to 12 litres for a typical auxiliary engine alone and easily cancels out the `red` cost advantage. The Scarab produces lower emmisions and makes less noise, of growing importance as contractors move to the enviromental standard ISO14002. And there is only one engine to fuel and maintain.
The DAF engine is very quiet, like those on all modern trucks. An auxiliary engine produces more noise particularly for the driver, which I find very tiring whether it`s a sweeper or a fridge rumbling away behind my head. And the public is becoming less tolerant of noisy machinery.

The Magnum Unidrive has to be a strong contender for the price-conscious contractor who wants to stay with a manual gearbox yet enjoy the Scarab economy and enviromental benefits. However for following a planer or municipal work the extra cost of Scarab`s hydrostatic drive would be well justified.

A tribute to our founder Rodger Hoadley

A tribute to our founder Rodger Hoadley
The passing of Scarab's founder undoubtedly marked the end of an era. Indeed Rodger's influence over the growth of the company and of many of the individuals within the organisation cannot be overstated.
 
Within our industry, Rodger was regarded as an icon and was well known for his innovative thinking and a rare passion for the product. His presence at the many events and functions that he attended, not just in the UK but also around the world, will be sorely missed.
 
It has been remarked that, had he been active in the Victorian age, Rodger's name would now be as famous as any of the other notable engineers of the time.
 
While it is true that, for this company and its employees, things will never be quite the same. Rodger's legacy is a strong, well-structured business, one that produces a first-rate product range and which is supported by the very experienced and knowledgeable management team and work force that Rodger took such great care to establish.
 
To paraphrase the words of another cigar-smoking icon 'He gave us the tools to do the job' and it is with these thoughts firmly in mind that we will continue to build on Rodger's strong foundations.
