Mining Equipment Wrie Rope Special Design Lebus Grooved Winch Drum
mining hoist
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.
The role of mining winch
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.
Classification of mining winches
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.
Precautions for winch operation
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
Service conditions of Lebus groove
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.
Pls measure the change of rope diameter under different load
