FIGURE 3.11 Design of the hydraulic system of the hinged wall
(1) hinged wall, (2) quick coupler - plug, (3) hydraulic cylinder for opening the side gate,
(4) hydraulic clamp locking cylinder, (5) sequence valve, (6) hydraulic lock
The hydraulic system for opening the hinged wall is supplied with oil from the tractor's
hydraulic system. The system is controlled by means of the lever of the manifold of the
tractor's external hydraulic system. Connections are made using hydraulic conduits
terminated with quick-couplers (2) marked with green plugs. Oil pumped from the tractor's
hydraulic system is supplied first to the sequence valve (5) and is directed to cylinders (3)
and (4) - consequently, the wall is unlocked and tilted. When the setting of the manifold lever
in the tractor is changed, oil is supplied through the other circuit to the second sequence
valve - consequently, the clamp is closed and locked.
