RoofFrameRigid, composite supporting frame on rectangular plan,consisting of electrically welded steel plates.The mechanical components of the machine are suitablysized, according to a 1.4÷1.5 factor, to withstand the dynamicstress due to the machine operation (supporting frame, hubs,axles, hopper supporting and lifting system, etc.).HopperThe hopper is fitted on the front side of the machine andconnected to the frame by means of a hinge.A hydraulic cylinder lifts and overturns the hopper when thewaste is to be dumped at a height. The lower part has ahinged skirt, operated by a hydraulic cylinder, which closesthe hopper while the waste is being dumped. The front sidehas a fan operated by a motor. This fan creates a vacuuminside the hopper and in the main broom compartment. Insideit, there is a polyester closed pocket filter connected to anelectric filter shaker.On the front right side there is a side broom whose rotation isoperated by a hydraulic motor, while its lifting and loweringare operated by a hydraulic cylinder.It is possible to install a side broom on the left side as well anda third broom for corner cleaning.Main broomIt consists of a sweeping roller whose rotation is operated bya hydraulic motor and whose lifting and lowering are operatedby a hydraulic cylinder. It is automatically adjusted by theself-levelling device.EngineThe diesel Lombardini Focs 702 engine (SR 1450 D) or theAMRE 36 V motor (SR 1450 B) drives the hydraulic systempumps.Front wheels– Pneumatic wheels– Superelastic wheels– They are independent, fastened to the frame by meansof a hub with built-in brake drum. The brakes arehydraulic. The parking brake is mechanical.Rear wheels– Pneumatic wheels– Superelastic wheels– The rear wheel is the driving and steering wheel. Thesteering is operated by a hydraulic cylinder connected tothe power steering. A hydrostatic variable delivery pumpwith servoassisted control supplies a drive hydraulicmotor for forward and reverse gear.
