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

What are the requirements for increasing the layers of wire rope winding on the winch drum?

Do not exceed the specified regulations for hoisting winches.

(1) One level for hoisting personnel or materials in a vertical shaft; two levels for hoisting materials exclusively.

(2) Elevators for personnel or materials in inclined tunnels: 2 levels; dedicated to materials handling: 3 levels.

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

(4) When winding more than two layers of钢丝绳 onto a reel, a hoisting winch should be used, and a transition rope wedge should be installed between the layers.

Production scheduling winches, dual-speed winches, rebar winches, transport winches, mining carts, bucketwheel excavators, hoisting winches, scraper conveyors.

What safety features are available for the winch upgrade?

Enhance Winch Overwind Protection

When the lifting drum exceeds 0.5 meters above the normal terminal stop position (or loading platform), the lifting winch model automatically shuts off power, functions as a coal mine hoisting winch, and can initiate braking action on the safety brake.

2. Enhance Winch Over-speed Protection

When the speed increase exceeds 15%, it must automatically shut off power and activate the safety brake.

3. Enhance winch overload and under-voltage protection

Overload and under-voltage protection devices, JTP hoisting winch, also known as overcurrent protection devices, are used to protect the hoisting motor from overload and short-circuit, as well as ensure the safe operation of other equipment. The under-voltage protection device activates a safe braking mechanism when the voltage exceeds the allowable limit.

Winches for production scheduling, two-speed winches, jacking winches, transport winches, ore cars, bucket wheel excavators, hoisting winches, scraper conveyors.
