11.2.3 Description Cabin lifting When the cabin lifting control is actuated, the pump contactor closes and the pump motor starts operating. At the same time, the Y45 valve opens and oils flows through the non-return valve and Y45 to the lift cylinder. If the lifting movement is interrupted, Y45 closes gently.
Cabin lowering When the cabin lowering control is actuated, the electromagnetic valves Y10 and Y45 open completely to allow the oil in the pressure lines to flow back into the oil reservoir. If the lowering movement is interrupted, first Y45 closes slowly and then Y10 closes. To ensure Y45 is completely closed before Y10 closes, Y10 receives a retarded holding voltage from the truck's logic card. The lowering speed cannot be adjusted, and is instead determined by the brake valve for the lowering action in the hydraulic unit valve plate.
