STEERING CLUTCHES AND BRAKES

Multi-disc, oil-bath steering clutches actuated by two indipendent control levers (in the first part of the stroke, they disengage the steering clutches, than in the final part the brakes are applied, thus controlling the steering of the machine). Hydraulic system pressurized by gear type pump. The oil is filtered by to full-flow filters: one metal mesh with magnetic rod on pump suction; the other, renewable, equipped with by-pass valve, in case of clogging, on the return line. Service brakes: oil bath, total wrap band type, working on the outer face of the steering clutch drums. Single, central pedal with hydraulic power control, to actuate the service brakes. Parking brake: automatically applied by safety lever.

UNDERCARRIAGE

Includes two welded box structure type track frames. The track frames are connected, in the front, by an oscillating cross-bar and are hinged, in the rear, on the sprocket drive shafts. Seven track rollers and two support rollers per side, permanently lubricated. Sprockets with replaceable toothed sectors. Idler wheels permanently lubricated, and hydraulic tension adjuster. Quantity of shoes per track chain:......................41 Width of standard shoes:..........................550 mm Track chains contact area: ......................32705 cm2 Width of standard shoes:..........................600 mm Shoe width: .............................................35675 cm2 Width of standard shoes: ..........................700 mm Shoe width: .............................................41620 cm2

FRAME

Load bearing with welded steel boxed structure on which the various groups are mounted. Mounted frontally on the oscillating cross-bar and to the track frames and to the transmission housing in the rear. EQUIPMENT HYDRAULIC SYSTEM

Hydraulic oil reservoir, equipped with level indicators, located in the back of the machine. Gear type feeding pump. Oil filtration by means of two total-flow filters: one metal mesh on pump suction line; one replaceable, with safety by-pass valve in case of clogging, on oil return line to reservoir. Three-spool, control valve. Single lever control for the first two spools of the control valve for: • raising/lowering/float of blade; • blade tilting. Two double-acting hydraulic cylinders incorporating stroke-end and quick dropping valves in the upper sleeve, operate the blade. An optional supplementary lever is available for the third spool. A safety locking lever, retains the equipment control in neutral, to avoid accidental manoeuvres.
