The serial winch products are suitable to move coal mining equipments in positive excavating working place. And they could be also used to release upper plate and withdraw the props in the working place ,convey largetonnage bulk material and schedule mining carts . The design of that winch includes to the perfect endlessrope series winch important foundation function. JWB50 endlessrope transportation winch is made up of motor, couple, reel, gearbox, electrohydraulicbrake, manual brake and switchcontrollersupport. The point of this graduation design is the gearbox. The transmission system realizes a closed circuit which has three pla gear step. Its transmission principle is simple, reliable and it has high efficiency. This winch uses two brakes to fulfill safe braking and working braking respectively, which make the witch’s braking more safe and effective. And this also makes the winch have the ablity of big tonnage ,soft starting and braking. JWB50 transportation winch has good blast protection property and braking property, big cope capacity, long longevity and high transmission efficiency. It also has pact structure, small external dimensions, approximately symmetrical structure ,long disappearance, basement in the shape of sleigh which is very convenient and smoothly moved ,low gravity center ,good stillness of basement. The installment is convenient by shore or ground anchor block, which make the winch work smoothly, reliably and safely.
