Increase the number of layers of wire rope winding on the winch drum

What are the requirements for increasing the number of layers of wire rope wrapped around the drum of a winch?

Raising winches is strictly prohibited beyond the specified regulations:

(1) Hoisting personnel or materials in vertical shafts, Mine Hoisting Winch, 1 level; dedicated for materials hoisting, 2 levels.

(2) Elevator shafts for personnel or material hoisting, 2 levels; dedicated to material hoisting, 3 levels.

(3) Elevator for personnel and materials during well construction: 2 levels

(4) When wrapping more than two layers of钢丝绳 on a reel, a transition rope wedge should be installed in the transition area between the wire rope layers.

Winches for production scheduling, dual-speed winches, column winches, transport winches, mining carts, bucket wheel excavators, hoisting winches, scraper conveyors.

What is the difference between the JTP hoisting winch and the JK hoisting winch?

JTP: J - Winch category, T - Hoisting winch, P - Disc brake, Mining hoisting winch. JTP refers to a hoisting winch with a drum diameter less than 2 meters and a disc brake type.

JK: J - Winch category, explosion-proof hoisting winch; K - Mining hoist; JK refers to hoisting winches with drum diameters greater than 2 meters.

Winch for production scheduling, two-speed winch, jacking winch, transport winch, ore cart, bucket excavator, hoisting winch, scraper conveyor.

What is a winch speed limiter protection enhancement?

Enhancing the hoist speed limiter protection involves controlling the container's running speed as it approaches the wellhead or bottom, and enters the deceleration phase. It ensures the hoist gradually slows down the container, reaching the designated position slowly and safely.

This is accomplished by the speed limiter. The speed limiter consists of three parts: the speed-limiting disc, the speed-limiting cam, and the self-aligning mechanism, which are installed on the hoist depth indicator and integrated with it.

Winches for production scheduling, dual-speed winches, rebar winches, transport winches, mining cars, bucket wheel excavators, hoisting winches, scraper conveyors.
