How to transport pneumatic winch correctly
Pneumatic winch should not only pay attention in use, but also pay attention in transportation to avoid unnecessary losses. Here are some precautions for everyone:
To improve the transportation, there should be a clear signal. After hearing the signal clearly, the driver should perform the operation. The driver should be assigned a special person. Generally, the driver should be held after the operation practice, non-drivers are not allowed to improve the operation. Improve the safety rules of the equipment, and improve the ratio of the small diameter of the equipment, the roller, the Sky Wheel, the leading wheel and the diameter of the wire rope of guide wheel is not less than 60. It is allowed to surround two layers of wire ropes on the drum of equipment specially used to improve materials.
If two or more layers of wire rope are surrounded on the drum, it is necessary to conform to the following rules: the edge of the drum should be higher than the outer layer of wire rope, and its height difference should not be less than 2.5 times the diameter of wire rope; it is necessary to set wood lining with spiral groove on the drum; Special attention should be paid to the critical section (equivalent to a quarter of rope ring length) of the steel wire rope transferred from the base layer to the upper layer, and the number of broken wires should be calculated, every quarter, the wire rope should be skewed to the orientation of a quarter circle.
When the steel wire rope head is consolidated in the drum, the following rules should be observed: equipment for fixing the steel wire rope should be set in the drum, and it is forbidden to fix it on the drum shaft; the rope eye on the drum is not allowed to have sharp margins and burrs, and the bending place is forbidden to form an acute angle to avoid deformation of the wire rope; It is necessary to permanently maintain three rings of wire rope on the drum as a conflict ring, in order to reduce the tension between the wire rope and the roller.
The spare wire rope used for timing experiments can be kept in or around the drum. It is necessary for the rim of the crown wheel to be higher than the wire rope in the rope groove, and the higher part should be 1.5 times larger than the diameter of the wire rope. It is necessary for the liner to be tightly fixed for the liner. When the liner wears up to the depth of the diameter of a wire rope or wears half of the diameter of the wire rope along the side surface, it should be replaced immediately.
