JH-5ton underground mining two speed hydraulicprop pulling winch/hoist

Two-speed prop-pulling winch is mainly applied in the coal mine back to caving, and also do auxiliary work for haul, transfer chute in transportation, Traction. Have the feature of compact structure, small size, low noise, smooth operation, speed and flexible, safe and reliable, manual brakes and power self-lock.,

Two-speed prop-pulling winch Introduction

Two-speed prop-pulling winch have fast and slow two speed, mainly used for underground coal mining working face, fully mechanized equipment and relocation of all kinds of mechanical and electrical equipment and other auxiliary transport work, as well as the underground mining working face,base parking lot, up & down mountains,mine car scheduling, and material handling work, also can be used for prop-pulling caving mining working face.This winch system used bevel gear drive type, simple structure, safe, reliable, and easy maintenance. Suited in small space work as the samller width and height of winch, have simple operation, match with speed control hand easy to use.

Feature

Two-speed prop-pulling winch have explosion-proof performance, mainly applied in the coal mine back to caving, and also do auxiliary work for haul, transfer chute in transportation, Traction.

Two-speed prop-pulling winch in the structure of the spherical worm gear, manual shift fork to achieve speed, fast speed more than slow to 5 - 6 times, Have the feature of compact structure, small size, low noise, smooth operation, speed and flexible, safe and reliable, manual brakes and power self-lock. compared with traditionaldouble speed spinning wheel.
