Lifting Slings Maintenance
Jun 12, 2017

(1) lifting slings in the course of the use, such as the rotation of the rotation is not flexible or not in place, should check the adjustment nut, and then check the following parts:

① If the tension spring of the pawl is damaged, if it is damaged, it should be replaced;

② If there is any jamming in the transmission mechanism, such as jamming, lubrication is bad, you should add the lubricating oil (or grease) at the movable connection of the transmission mechanism. If the guide pin is too tight, should be appropriate to loose nuts. If the connection is loose, the transmission tube or other bar deformation, it should be corrected;

③ buffer spring stretch is too small, if too small, you should shorten the buffer spring connection length of the rope.

(2) should be used in the Lifting Slings on the indicator plate to prevent the paint off. Once discovered, need to promptly fill the original signs of the paint.

(3) For lifting rope on the wire rope, should be timely cleaning and coated with lubricating oil or grease, especially the wire rope bend.

(4) For the main force components, rings, spin locks, ear panels and cable shackles, in the normal use of clearance, at least every 3 months to check once, no cracks and serious deformation.

(5) All oil cups, including oil cups of ratchet mechanism, oil cups on sliding housings and oil cups for rotary lock boxes, should be filled with lubricating oil in accordance with the conditions of use.

(6) often check the rope card is loose, the buffer spring is excessive stretching, found that the problem in time.

(7) each spreader shall not exceed the rated weight, the buffer spring shall not be excessive stretching.

(8) lifting process should be a smooth lifting, to avoid lifting slings and cranes or other equipment, such as the impact of each other and deformation.

 Under normal circumstances, lifting slings in the use of the process, if the hanging material overload, it is easy to cause it to break, and in the event of a break, some customers in order to save costs, unauthorized welding sling to continue to use, do not know this approach But the use of taboo.

    If the customer needs to weld the hook, you can purchase the welding hook directly, the welding hook product and the so-called user's private welding hook are completely different concept, Welding hook is not unauthorized on the hook for welding, I hope users do not confuse.

    If the hook is in use when the break, the user can not be used after welding, ordinary welding is not able to make the hook again carrying heavy objects, hooks in the manufacture of layers after forging, forging after the hook has a certain Toughness, this toughness will make the hook product will not easily break, generally referred to here broken, refers to the hook when the operation suddenly broken the goods directly fall, causing damage to the goods or casualties, and a certain toughness of the crane Hook, if the hook can not be carried in the work of the weight will not suddenly break, the first distortion will appear, more serious when there will be cracks, if the user often check the lifting slings products are intact, generally do not suddenly cut off Situation, and unauthorized welding of the hook is not any toughness, simply can not be used, and must replace the new product.
