Hydraulic lifting bridge
Working principle and operation of lifting bridge:
The operating medium of the lifting bridge is high-pressure oil, which controls the hydraulic cylinder through the hydraulic valve.
The working principle of the hydraulic system is shown in the figure below:
Lifting operation:
When the vehicle is stationary and the engine is idling, open the protection unit of the hydraulic control valve, lift the handle to the lifting position, the hydraulic oil enters the lower chamber of the working cylinder through the high-pressure oil pipe, and the piston rod is pushed out
The push arm 4 of the working cylinder rotates on the rotating shaft 2. When the stroke is reached, the roller 5 on the push arm presses the top of the equalizer arm 11. If the working cylinder continues to extend, the load of the driven axle decreases, and the rear suspension
The leaf spring of the frame will deform; When the load is reduced to 0, the leaf spring stops deforming, the hydraulic cylinder 8 continues to extend, the balance arm 11 turns over the balance shaft, and the driven axle rises. When the leaf spring stops deforming
After that, the vehicle frame starts to rise; When the lifting bridge reaches the limit position, release the operating handle, and the handle will automatically return to the middle position. The hydraulic working cylinder is locked hydraulically, and the lifting bridge is lifted and locked for operation
Handle.
Drop operation:
When the vehicle is stationary and the engine is idling, open the protection unit of the hydraulic control valve, press the handle to the falling position, the high-pressure oil enters the upper chamber of the working cylinder through the high-pressure oil pipe, and the piston rod retracts
When the push arm 4 rotates on the rotation axis 2, the bridge will descend due to its own gravity. When the bridge falls to the ground, the piston cylinder continues to retract to the limit position, pushing the push arm 4 and the roller 5 up to a distance of 11 from the balance arm
The highest point of about 60mm. After releasing the handle, the handle will automatically return to the middle position. The hydraulic cylinder is self-locking. Then the bridge will fall to the ground. Lock the handle.
