Problems that should be paid attention to and maintenance measures in daily use of slings
Henan Weihua Heavy Duty Crane Machinery Co., Ltd. designs and manufactures various non-standard hooks and spreaders for producing 3.2T-1000T driving hooks, insulated hooks, explosion-proof hooks, rotary hooks, rolled pulleys, ladle gantry hooks and free forgings below 10,000 kg.
Precautions and maintenance
(1) During use, if the rotary lock is inflexible or inadequate, the adjustment and adjustment nut should be checked and then the following parts should be checked:
① Whether the tension spring of the pawl is damaged, if it is damaged, it should be replaced;
② Whether the transmission mechanism is stuck, if it is stuck, it is poor lubricating, lubricating oil (or grease) should be added to the movable connection of the transmission mechanism. If the guide pin is too tight, the nut should be loosened properly. If the connection is loose, the transmission tube or other rods are deformed, it should be corrected; ③ Is the stretching amount of the buffer spring too small? If it is too small, the length of the wire rope connected to the buffer spring should be shortened. (2) During use, the indicator paint on the spreader indicator board should be prevented from falling off. Once discovered, the paint that is marked with the original indicator must be supplemented in time. (3) For the wire rope on the spreader, it should be cleaned and applied with lubricating oil or grease in time, especially where the wire rope bends should be. (4) For the main stress-bearing components, lifting rings, rotary locks, ear plates and rigging shackles, under normal use, they should be inspected at least once every 3 months, and there must be no cracks or serious deformation.
(5) All oil cups, including the ratchet mechanism oil cup, the oil cup on the sliding bearing seat and the oil cup of the rotary lock box, should be filled with lubricating oil at the main movable connections according to the use situation. (6) Check frequently whether the rope clamp is loose and whether the cushioning spring is overstretched, and deal with problems in time if they are found.
(7) Each type of spreader must not exceed the rated lifting weight, and the cushioning spring must not be overstretched.
(8) The lifting should be lifted smoothly during lifting to avoid deformation due to collision between the spreader and crane or other equipment.
