overview of the Wich drum
The role of the winch drum is mainly to transfer the speed and
torque of the motor to it through the spindle into the linear speed
of the wire rope around it, in order to lift and lower the object.
According to the different manufacturing process, the drum
structure of the hoist can be divided into casting- welding mixed
type (supporting wheel for casting, drum for welding) and welding
type.
Drum & drum shaft
The drum diameter not less than 19 times of the wire rope diameter.
The drum wall can withstand the wrapped tight force of wire rope;
the side can withstand the lateral force produced by wire rope.
The distance between drum side plate peripheral to the outermost
roll rope not less than twice of the wire rope diameter.
Precautions for the use of crane winch
1. The wire ropes on the crane drum should be arranged neatly. If
overlap and oblique winding are found, they should be stopped and
rearranged. It is forbidden to pull the wire rope by hand or foot
in rotation. The wire rope shall not be completely released, at
least three laps shall be reserved.
2. crane wire rope is not allowed to knot, twist, in a pitch break
more than 10%, should be replaced.
3. In the crane operation, no one shall cross the wire rope, and
the operator shall not leave the hoist after the object (object) is
lifted. Objects or cages should be lowered to the ground when
resting.
4. In the operation, the driver and signalman should maintain good
visibility with the lifting object. The driver and signalman should
cooperate closely and obey the unified command of the signal.
5. In case of power failure during crane operation, the power
supply should be cut off and the lifting object should be lowered
to the ground.
