A mechanical device used to pull a load by means of a wire rope wound around a drum. It is mainly used for pulling vehicles underground or on the ground, removing the pillar of coal mining face and other auxiliary transportation work.
Mechanical equipment used for pulling load moving with wire rope wound on the drum, mainly used for underground or ground traction vehicles in mines, removing pillars of coal face and other transportation work.
According to the power is divided into electric, pneumatic and hydraulic 3. According to the way of force transmission between wire rope and drum, there are two kinds of winding and friction wheel; According to the use of dispatching winch, return column winch, endless rope winch and transport winch 4.
The driver should pay attention to the operating conditions and the wear of the wire rope at any time. When the load changes and improves, the driver should stop 0.5m above the ground and continue to rise when there is no problem. The driver shall not leave his post until the suspended object falls completely to the ground. When resting or suspending operations, objects or cages must be lowered to the ground. After work, should cut off the power supply, close the switch box
1. The flanges of drum shall be perpendicular to drum wall at any conditions,even under the load.
2. The rope must be kept under tension in the process of spooling so that the rope will be crushed against groove wall. When spooling can not meet this condition,a press roller shall be used.It is generally recommended that the tension of the rope should be at least 2% breaking tension or 10% working load.
3. The fleet angle range should generally never be more than 1.5 degrees and not less than 0.25 degrees.
4. When the wire rope released from the drum goes around the sheave,the center of sheave should be over the center of drum.
5. The rope must be kept round,not loose,even under the maximum load.
6. The rope must be anti-rotation structure.
