What are the safety devices of KBK monorail crane? In order to ensure the safety and reliability of lifting operation, the crane is equipped with relatively complete safety devices, so as to protect the parts or remind the operators to pay attention in case of accidents, thus playing the role of safety protection.
1. Each overflow valve in the hydraulic system: it can suppress the abnormal high pressure in the circuit to prevent damage to the hydraulic oil pump and motor and prevent them from being overloaded.
2. Boom luffing safety device: when an unexpected accident occurs and the high-pressure hose or oil pipe in the boom luffing oil cylinder circuit bursts or is cut off, the balance valve in the hydraulic circuit acts to lock the working oil from the lower chamber of the oil cylinder to prevent the boom from falling, thus ensuring the safety of the operation.
