JTB, JTKB series mine explosion-proof hoisting winches

This series of winches are used for hoisting or transportation in places where there are explosive mixtures of gas or coal dust underground in coal mines. The 1.2-meter and 1.6-meter explosion-proof hoisting winches are basically the same as the JTK winches, only the reducer, working and safety brakes, and depth indicators have been partially modified, and the operating mechanism has been replaced.

This series of winches are used for hoisting or transportation in places where there are explosive mixtures of gas or coal dust underground in coal mines.
The 1.2-meter and 1.6-meter explosion-proof hoisting winches are basically the same as the JTK winches, only the reducer, working and safety brakes, and depth indicators have been partially modified, and the operating mechanism has been replaced.
The winch is easy to operate and maintain, safe and reliable, and is suitable for small and medium-sized mines. The motor and electric control of the winch have explosion-proof performance, and there are devices such as lifting, current and voltage display, deceleration alarm bell, and over-roll protection.
