HYDRAULIC SYSTEM
The hydraulic system provides power to the steering, skip swivel and skip tip functions.
The hydraulics consists of an engine driven pump drawing oil from a tank. In the tank there
is a suction strainer, filter and breather cap fitted, the tank is made from a transparent
material and the level of oil can be seen through the side of it, a max and min decal shows
the operator the correct level. The pump incorporates a load sensing valve for the steering,
and also has two outlets one for the steering and one for the main system. A return to tank
filter is fitted and is of the replaceable cartridge type.
Steering of the dumper is by means of a double acting hydraulic cylinder, mounted at each
end on the two half's of the chassis with the centre point articulation this cylinder when open
and closed will provide the steering lock to lock operation. The supply of oil is governed by
a steering valve unit.
