As a part of hardware rigging, wire rope rigging plays a very important role in lifting engineering. However, wire rope rigging can not be used casually, and there are many things that must be paid attention to during hoisting. Next, I will introduce the requirements for the use of wire rope rigging in the hoisting process. ? 1, when lifting rigging with aluminum alloy pressure joint, metal pottery should not be subjected to radial force or bending moment. 2. When lifting objects, objects such as metal pins passing through soft cable eyes should have sufficient connection strength, and the diameter should not be less than 2 times of the nominal diameter of wire rope slings. 3, wire rope rigging shall not be dragged on the ground; Rigging with welding scars shall not be used; Wire rope rigging shall not be used as grounding wire for electric welding. 4, hook, shackle shall not be welded or drilled, can not have cracks, acute angles, overheating and other defects that affect the safe use. 5. The thickness of the lug plate and other rigging accessories connected and contacted with the shackle pin shaft shall not be less than the diameter of the pin shaft. 6. When lifting the lifting load, the following requirements shall be met: the limbs of the rigging shall not have any possibility of knotting; Terminal connection mode is correct and reliable; The bending curvature radius of rigging is more than 2 times of the nominal diameter of wire rope; When using rigging, the natural kink angle shall not be squeezed, but the terminal eyelet, sleeve or plug connection and its accessories shall be safe and reliable; Multi-limb rigging shall not be intertwined.
7, the use of units should have safe use, maintenance procedures or corresponding rules and regulations; Files should be established for the wire rope rigging of the unit.
8, wire rope rigging should be stored in a special rigging room, and neatly arranged, fixed firmly.
9, wire rope rigging room should have wire rope rigging signs, indicating the specifications of the wire rope rigging, model, rated load, safety factor, etc. , users should be familiar with and choose correctly.
