JJM Type Winch for mining and building contruction

Slow winch (JJM) is mainly used for structural installation, cold drawing of steel bars and tensioning of prestressed tendons.

The winch must be reliably anchored during use to prevent slippage and overturning during work. There are four common ways to fix the hoisting machine: bolt fixing method, horizontal wood fixing method, pile fixing method and weight fixing method, as shown in the following fixing method diagram.
