Seat Steering wheel Frame Bumpers Hopper hood Hopper Right side lid Main broom Engine hood Side broom Dashboard Control levers Roof

Frame Rigid, composite supporting frame on rectangular plan, consisting of electrically welded steel plates. The mechanical components of the machine are suitably sized, according to a 1.4÷1.5 factor, to withstand the dynamic stress due to the machine operation (supporting frame, hubs, axles, hopper supporting and lifting system, etc.).

Engine The engine, Lombardini LGW 627, drives the hydraulic system pumps.

Pneumatic wheels Superelastic wheels They are independent, fastened to the frame by means of a hub with built-in brake drum. The brakes are hydraulic. The parking brake is mechanical.

Pneumatic wheel Superelastic wheel The rear wheel is the driving and steering wheel. The steering is operated by a hydraulic cylinder connected to the power steering. A hydrostatic variable delivery pump with servoassisted control supplies a drive hydraulic motor for forward and reverse gear.

Dashboard Fitted on the upper part of the frame and under the steering wheel, the dashboard houses the machine warning lights and instrumentation.

Hydraulic system In the first circuit a variable delivery pump feeds the drive hydraulic motor (rear wheel). In the second circuit a gear pump feeds a lever double-acting distributor. The distributor operates the lifting cylinders and the broom motors. All circuits are protected by suction filters and safety valves.

Electrical system 12V electrical system supplied by an alternator operated by the motor. The circuits are protected by lamellar fuses housed in a relevant fuse box.

The hopper is fitted on the front side of the machine and connected to the frame by means of a hinge. A hydraulic cylinder lifts and overturns the hopper when the waste is to be dumped at a height. The lower part has a hinged skirt, operated by a hydraulic cylinder, which closes the hopper while the waste is being dumped. The front side has a fan operated by a motor. This fan creates a vacuum inside the hopper and in the main broom compartment. Inside it, there is a polyester closed pocket filter connected to an electric filter shaker. On the front right side there is a side broom whose rotation is operated by a hydraulic motor, while its lifting and lowering are operated by a hydraulic cylinder. It is possible to install a side broom on the left side as well and a third broom for corner cleaning.

33014812(1)2005-07 A USER MANUAL Stability Machine stability depends on the conditions in which it is used. If the machine is used within the conditions of use specified in the manual, it is stable.
