When accident happens, when the high pressure hose or oil pipe in the cylinder circuit of the tower crane boom amplitude change is burst or cut off, the balance valve in the hydraulic circuit will work to lock the working oil from the lower chamber of the cylinder, so that the tower crane boom will not fall, thus ensuring the safety of operation.

Telescopic safety device for tower crane boom

When accidents happen, the boom telescopic cylinder loop in the high pressure hose or tubing burst or cut off, the hydraulic circuit of the balance valve on the role of the lock from the lower chamber of the oil cylinder working oil.

so that the crane will be their own retraction, thereby ensuring the safety of the operation.

Each overflow valve in the hydraulic system

Abnormal high pressure in the circuit can be suppressed to prevent the damage of the hydraulic pump and motor, and to prevent overload.
