Common Hydraulic System Components
1. Gear pump or piston pump: Supplies a continuous flow of high-pressure hydraulic oil to the cylinder.
2. PT pneumatic control distribution valve: Located on the oil tank or pipeline, it precisely controls the cylinder's lifting, intermediate stopping, slow lowering, and rapid lowering.
3. Limit valve: When the cylinder reaches its maximum lift height of 4.2 meters, the limit valve automatically cuts off the high-pressure oil supply; this prevents damage caused by over-extension and ensures safe dumping operations.
