What are the safety measures for car cranes to eliminate hidden dangers?
Lifting lift mechanism The brake is actually a small single-pole single-acting hydraulic cylinder, the brake is normally closed, the braking force depends on the spring force in the cylinder.
In the oil circuit installed in the hydraulic lock or balance valve, it is not necessarily able to fully guarantee the mechanism can be locked after the brake, hydraulic cylinder (hydraulic motor) sealing is also a key factor in restricting the locking effect.
Balance valve is essentially a one-way valve and external control of the combination of the valve from the combination of the combination of the valve, it is installed in the car crane and lock the principle of locking and hydraulic lock exactly the same, that is installed in the oil return,
The reverse oil path of the hydraulic check valve is only connected when it controls the oil input to a certain pressure oil
