Scarab Minor Road Sweeper
The Scarab Minor VM Hydrostatic Sweeper is one of the most powerful compact urban road and precinct sweepers, incorporating the latest in technology and design. Fitted with the VM Motori 3.0 litre turbo charged diesel engine, with indirect injection, meeting and exceeding the Euro IV regulations, this engine reduces fuel consumption and exhaust emissions. The Scarab hydrostatic drive system gives the vehicle a travel speed of 65 kph and a gradeability of 25% (1 in 4). The hydraulic drive is controlled by a proven electronic system that optimises the engine power, to give very smooth acceleration/deceleration and variable governed engine speed for sweeping with the additional benefit of cruise control. The machine is mounted on a 3500 kg G.V.W. sprung chassis. The standard vehicle comes with fully equipped cab, power steering and servo-assisted brakes. Technical innovation and advanced design make the Scarab Minor an extremely versatile compact urban/precinct sweeper, capable of undertaking most arduous sweeping tasks including those normally undertaken by larger truck mounted sweepers.

ELECTRICAL SYSTEM: Fully colour coded, negative earth - 12 volt 66 Ah maintenance free battery - 85 amp Alternator - 2.2kW starter motor. System fully protected with fuses situated in the cab for easy access. Full road lighting with reverse bleeper - rotating beacon - brake lights, etc.
ENGINE: VM Motori 3.0 litre 494 HT4 series diesel engine with turbocharger and indirect injection meeting the latest Euro IV regulations, ensuring reduced fuel consumption and exhaust emissions, yet can develop 68.5 kW at 3200 rpm. The VM engine to suit the Scarab application has a capacity of 2996 cc with a maximum torque of 230 Nm at 1900 rpm
TRANSMISSION: Scarab designed, continuously variable hydrostatic transmission with the hydraulic pumps coupled direct to engine. The hydraulic motor driving the rear axle via a propeller shaft. The vehicle speed is controlled by a single electronic foot pedal via an electronic processor, which accurately matches the engine speed to the hydrostatic drive, ensuring smooth acceleration and maximum economy. The drive system has 2 modes, as above for driving, and a sweeping mode that enables the engine rpm to be set for the brush and suction fan drive. The foot pedal then only controls the vehicle sweeping speed by the hydrostatic system. The Scarab Minor VM is fitted with an anti-stall device to prevent overloading the engine. Forward and reverse is selected by a single control lever. For extra driver comfort whilst sweeping a cruise control is fitted.
