 The new M6 sweeper is a high-capacity unit designed for use with surface dressing or tack coats after milling operations Designed to be robust, durable and effective, the M6 road sweeper is a high-output system designed for fast mounting to any type of truck chassis with a GVW from 12-18tonnes. The machine can provide an efficient and economical solution for ancillary maintenance works such as surface dressings, tack coats after milling. 

Scarab M6 Road Sweeper

Marketed by 3D in France, under the Scarab name in the UK and by BOMAG on other markets, where it is known as the FS6000, this machine is designed for worldwide use. The machine comes with a sophisticated CANbus control system that passes control instructions for sweeping functions through an ergonomically-designed panel. The system features self-diagnostics as well as a range of sweeping data acquisition functions, to monitor condition and performance and help identify any maintenance issues early on.

The waste tank features a 6.35m3 capacity and is made from stainless steel, for corrosion and abrasion resistance. The water pump has a suction filter and is powered by a hydraulic motor that supplies water to the brushes and suction nozzle. Four water jets are fitted to the nozzle at 90° intervals and provide a dust-suppressing spray, while the water tank has a 1,250litre capacity. The suction inlet tubes have automatic separator flaps and there is a 1.5m² suction filter screen that tips for cleaning. Bulky waste can be stored in two large compartments on either side of the tank.

The all-steel, 250mm diameter suction nozzle is fully adjustable, while the 400mm diameter wide sweeping brush and 650mm diameter side brush are powered by direct-drive hydraulic motors. The pneumatic system is supplied by the auxiliary air intake on the chassis and is equipped with a pressure regulator and a filter/water separator.

Fenland District Council stay with Scarab
Fenland District Council continue their long association with Kent based manufacturer Scarab Sweepers Ltd and recently took delivery of another Scarab Merlin Hydrostatic heavy duty road sweeper mounted on a DAF 45 series 12 tonne GVW chassis. Mark Gregory, Fleet Manager of Fenland District Council commented on the manoeuvrability of the chassis, extremely impressive suction power and large payload capacity necessary for the arduous conditions encountered daily in the Fenlands.

Commented Mark, “The Scarab vehicles that we have in our fleet are essential to us performing our street cleansing duties in Fenland. They complement the work completed by compact and pavement sweepers, covering many tens of thousands of miles each year.”

“ Fenland District Council has its own, four bay, well equipped workshop facility staffed by 7 fully skilled apprentice trained technicians. The work load is varied with cars, vans, trucks, tankers and refuse vehicles to look after.” Mark Gregory proudly boasts of the range of work undertaken by the workshop and its ethos of walking towards any challenge thrown upon it.”

“The technicians are keen to keep up with the advances of modern vehicle technology. A training plan maps the training needs of the staff to prepare them for the challenge of keeping trucks where they belong, on the road performing their duties. Staff have attended the  Scarab  training centre to learn in detail the maintenance, repair and fault finding diagnostics of the  Scarab  chassis mounted sweeper. Future plans are to receive training on the latest CANbus system as fitted to the latest  Scarab  acquisition.”

“The principal of good regular and effective preventative maintenance has clearly paid off. The  Scarab  “3000” sweeper on a DAF 45 series chassis is now 13 years old and in daily use. Under normal circumstances a vehicle would not be kept on the fleet for such a long period of time. However there is always a case for judging each case on its merits and without question this vehicle has proved to be an asset worth looking after.”

The issues in  Fenland might well be unique. Although many rural local authorities have to respond to the effects of agriculture on the highway, in  Fenland with its particular soil quality, and very open nature, blown topsoil and the effects of agricultural activities, such as sugar beet harvest and transport, means that frequency of sweeping has to be such that operatives are always on top of these issues. As a result  Fenland aim to sweep all kerbed roads at least every four weeks, with many on a daily or weekly pattern, dependant upon need and location.

“The new Scarab Merlin sweeper with its larger capacity (over 6000kgs) will help to improve even further the efficiency in sweeping the rural villages at the required frequency to achieve Fenlands targets for the cleansing Best Value indicator BVPI 199”. commented Mark Mathews, Environmental Services Manager, adding “ Fenland is proud of the improvements made through its “Streets Ahead” programme over the past three years that has seen substantial investment in cleansing, street sweeping and “Fly tipping” removal. The best value indicator BVPI 199, which is a measure of street sweeping and street cleansing, has improved from 24% below standard to 9% within these three years. This is without doubt due to the ability of Fenlands sweeping fleet and their drivers to keep on top of their work during all but the most difficult times of year. This effort is complemented by other cleansing staff who are committed to delivering a high standard. This commitment has also been equally matched by the Council in providing staff with their preferred options when it comes to the best possible tools to get the job done.”

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.”

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.

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.

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.

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.


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.
