　　1、 JD-4 scheduling winch parameter table:

　　2、 Braking device for D-4 scheduling winch

　　There are two brake devices with the same structure on the winch, which are fixed to the base through brackets. The left brake, usually installed on one side of the motor drum, controls the rotation and stop of the drum. The right brake installed on the other side of the brake wheel acts as a clutch. When the brake wheel is tightened, the drum enters the working state of pulling heavy objects. The left brake device also has a safety braking function. When the winch is powered off, overloaded, or other reasons cause an increase in current, the current limiting thermal relay device of the magnetic starter installed on the winch will automatically power off the winch motor. At this time, the left brake device will perform emergency braking to achieve the purpose of safety braking. The brake material is made of asbestos material. The asbestos brake band is fastened to the brake with rivets during braking. Simply pull up and hold the brake belt tightly around the drum or brake wheel to stop the winch or rotate the rope.

　　3、 JD-4 scheduling winch precautions: The friction performance of the brake band in the braking device should meet the following requirements:

　　During the friction test Flame burning and flameless burning should not occur Explosion should not occur in a sealed explosion-proof box.

　　During the friction test, the surface temperature of the specimen and test disk should not exceed 150C.

　　3. The material of rivets should be copper or stainless steel The depth of the countersunk hole for rivets should be 2-3mm

　　4. The performance requirements of the selected non-metallic materials should comply with the flame retardant and anti-static regulations of MT113 1995.

　　5. The winch driver must operate behind the rope guard and is strictly prohibited from operating on the side of the winch or in front of the drum (rope side).

　　6. When lowering the vehicle, it should be coordinated with the hook operator and there should be no excess rope left to avoid sudden acceleration and damage to the steel wire rope when passing over a slope change point.

　　7. When lifting a vehicle, if the vehicle passes over a slope change point, the driver should stop the vehicle in a timely manner according to the signal instructions, and it is strictly prohibited to roll over or park improperly.

　　8. Under normal circumstances, vehicles are strictly prohibited from parking on the slopes of the roadway; When a vehicle is parked in a sloping lane due to an accident or other reasons, the driver should tighten the brake, pay attention to the signal, and strictly prohibit leaving the post.

　　9. When dealing with a vehicle falling off the track, it is forbidden to use a winch to pull or forcefully pull it.

　　4、 Working conditions of JD-4 scheduling winch

　　1. Environmental temperature -10-40 ℃

　　2. The relative humidity of the environment shall not exceed 95% (25 ℃)

　　3. The altitude is below 2000m.

　　Attention: The methane, coal dust, hydrogen sulfide, carbon dioxide, and other substances in the surrounding air must not exceed the safe levels specified in the Coal Mine Safety Regulations. The working mechanism of the winch is a drum winding type, and the transmission type is planetary gear transmission.
