HSZ Type Chain Block
HSZ Type Chain Block has a circular stamping shell with a compact and lightweight structure, making it convenient for storage and carrying. Built-in safety self-locking brake. It automatically locks after lifting heavy objects to prevent falling. It can help customers solve the problems of short-distance heavy object lifting and positioning in power-off environments.
Compared with electric hoists, it is not restricted by wires or power sources, has a low failure rate, is easy to maintain, has a high cost performance, and is suitable for low-frequency intermittent lifting.
