3.2.7 SUPPORT HYDRAULIC SYSTEM

The parking stand hydraulic system extends the stand to support the trailer disconnected

from the tractor or when it is parked in the garage after use. Using parking stand hydraulic

system drawbar height can be adjusted when hitching and disconnecting the trailer. The

parking stand hydraulic system is supplied with oil by the tractor hydraulics. The parking

stand is extended or withdrawn by extending or withdrawing a hydraulic cylinder. The support

cylinder is controlled by means of the hydraulic oil manifold of the tractor's external hydraulic

system .

FIG. 3.10

Straight support hydraulic system construction and diagram

(1) hydraulic support, (2) quick coupler, (3) valve, (4), (5) information decals

The straight hydraulic support was used for the trailer - Figure (3.10). Lowering the support

(1) is carried out by opening the valve (3). Hydraulic oil supplied from hydraulic selective

control valve extends the cylinder ram to the desired height. After the pressure is hydraulic

line is reduced, withdrawal of the parking stand to transport position is forced by means of

springs. Hydraulic line which controls straight support is marked with decal (4) near the

connector. The valve (3) locks the support in a fixed position.
