There are many hoisting methods. For safety reasons, Crane rental company It will tell you some things to avoid when lifting. When lifting the equipment, the lifting point shall be determined, and the lifting lug shall be selected and installed. If there is a lifting lug on the equipment body, its own lifting lug can be used; If there is no lifting lug on the equipment body, the lifting lug for installing the equipment shall be selected and manufactured according to the requirements of on-site equipment lifting and relevant specifications. When making the lifting lug, select the material consistent with the body and check the material.

The following points shall be avoided for large crane lifting belt:

① Overload is strictly prohibited.

② When working with two lifting belts, hang the two lifting belts directly on the double hooks. The slings are respectively suspended at the symmetrical force center of the double hooks; When four lifting belts are used, every two lifting belts are directly hung on the double hooks. Note that the straps in the hook shall not overlap and squeeze each other, and the straps shall be symmetrical with the force center of the hook.

③ When using the lifting belt, hang the lifting belt directly on the force center of the hook, not on the top of the hook.

④ During hoisting operation, the sling shall not be crossed or twisted, nor knotted or twisted. Use the correct lifting belt special accessories when connecting.

⑤ When goods loaded with sharp corners and edges are encountered, the slings must be protected by sheathing, angle protection and other methods to extend the service life of the slings. The use of slings on rough surfaces is prohibited. Prevent sling from being scratched by corners and rough surfaces.

⑥ Double yoke binding is safer.

⑦ When using the sling, the bending part of the hook causes uneven force on the flat sling in the width direction, which is affected by the inner diameter of the hook. When the diameter of the hook is too small, the hook is not fully combined with the eyelet of the webbing, so the correct connector should be used for connection.

⑧ When lifting pipe objects, the correct lifting method should be used. If the lifting angle is too large, there will be potential safety hazards.

⑨ Do not press objects on the lifting belt, which may damage the lifting belt. Do not try to pull out the lifting belt from below, which may cause danger. It should be padded with articles to leave enough space for the sling to be taken out smoothly.

⑩ Do not drag the sling on the ground or rough surface, After use, the sling shall be hung for storage.

Slippage transportation mode of winch towing cable for large hoisting: during hoisting, the sliding transportation mode of winch towing cable is generally adopted. This method requires the design of a traction winch in front of the steel drawbar. In this method, roads with high requirements for equipment sliding should not only be compacted, but also leveled. During the operation, the overall coordination and operation coordination of lifting shall be coordinated to ensure the continuity and stability of the lifting process

For the reinforcement measures of lifting equipment skirt, if the equipment is heavy and bulky, the stress on the tail skirt will be concentrated during lifting. In order to prevent the skirt from deformation during lifting, reinforcement measures must be taken at the bottom of the skirt, and triangular or cross support frames must be added to reduce the deformation of the skirt during lifting, so as not to affect the positioning speed of the equipment.
