What will you use Roof Crane wire rope need to pay attention to?

One. The size of the grooves, the angle of the bag and the wall of the trough to the bottom of the pulley should be in accordance with the regulations. Otherwise, the corresponding bending stress and extrusion force of the wire rope will increase.

Two. Limit or eliminate elastic vibration of wire rope. In the design of the mechanism, the designer usually treats the wire rope as a rigid body, when in fact the wire rope is an elastic body. During acceleration, deceleration or emergency braking, the wire rope stores or releases part of the energy, which causes the hoisting equipment to vibrate violently. In order to improve the service life of the steel wire rope and improve the working performance of the whole mechanism , the elastic vibration of the steel wire rope should be limited or eliminated as much as possible , so as to reduce the dynamic tension of the steel wire rope . Only choose the best start and stop the curve, can effectively restrict the elastic vibration of equipment during acceleration and deceleration. Reduce the damage of steel wire rope, enhance the reliability of the equipment operation and increase comfort.

Three. To prevent the wire rope skipping rope. If the gap between the pulley and the pulley is too large if the anti-skipping device or the anti-skipping device is not installed, If the diameter of wire rope exceeds 20% or the rigidity of rope-proof device can not meet the requirement of application, the rope will be damaged.

Four. The material properties of pulley or hoisting drum should meet the specified requirements, otherwise the extrusion stress of wire rope will be too large.

Five. To prevent the wire rope from twisting or bending at the first installation, unevenly arranged on the reel.

Six. The pulley or roll drum shall be in a proper position, Otherwise, the angle of the rope will increase when the wire rope is wound or around the pulley and the roller. That is, the angle between the central line of the wire rope and the axis perpendicular to the pulley or drum is greater than 4 °.

Seven. Avoid the following situations: improper fixing of the end of the wire rope; joint of the wire rope with the wedge. The direction of the main force rope is not correct. Using clamp joint rope is too short, and there is no banding, bolt too tight or too loose, etc . The screw, screw less number and spacing of unreasonable or selection does not match with wire rope.
