It is an important production supplier of lifting slings.

Application characteristics of steel wire rope chuck

Use of wire rope clip head: first, carbon steel cast wire rope clip head commonly used static knot, cable tension line fastening, such as power, communication lines, such as binding and fastening. Forged wire rope chuck is often used for lifting and lifting, such as a variety of engineering cranes, metallurgical and mining equipment, oil derrick, port railway loading and unloading, forestry machinery, electrical equipment, aviation and maritime, land transport, engineering rescue, salvage sunken ships, factories and mining enterprises lifting, hoisting, traction rigging. Stainless steel wire rope Chuck because of its corrosion resistance, not easy to rust, it is used in ship accessories, chemical plants, radiation and other environment. Second, features: with the steel rope and other strength, safe use, beautiful appearance transition smooth, lifting work safety load, shock load can be resistant, long service life. The use of wire rope clip points for attention: not long-term use, should be regular inspection, periodic scrap, not repeated use. (1) the size of the clip head should be suitable for the size of the wire rope, the inner net distance of the u-ring should be 1-3mm larger than the diameter of the wire rope, the net distance is too large to tighten the rope. (2) when in use, tighten the U-shaped bolt until the wire rope is squashed about 1/3. Due to the deformation of the wire rope after loading, the wire rope must be tightened a second time after loading to ensure the reliability of hail. If need to check the steel wire rope in the force, whether the rope card slip, can take an additional safety rope card to carry out. The safety rope clip is installed about 500mm away from the last rope clip. After the rope head is released through a safety bend, it is clamped with the main rope. In this way, if the clip slips, the safety bend will be straightened, easy to find and timely reinforcement. (3) the distance between the rope clips is about 6-7 times of the diameter of the wire rope. To arrange the rope clips in a straight line, the U-shaped ring should be stuck on one side of the rope head, and the press plate should be placed on one side of the main rope.

Rules for the use of lifting tongs

How does a jack work

1. Jack is a light and small lifting device that lifts heavy objects in a small stroke through a top bracket or a bottom bracket. Different types of jacks have different principles. Common hydraulic jacks use Pascal's law, i. e. the pressure of the fluid is the same everywhere, so that the piston can be kept stationary. 3, and the screw jack is through the reciprocating pull handle, stack ratchet clearance rotation, through gear rotation to make the sleeve lifting and lowering, to lift the pull function.

What are the reasons for the broken wire rope

There are two main types of wire rope fracture, one, overload fracture, that is, the wire rope by pulling force greater than the wire rope by the bearing force of the wire rope was pulled off. Second, the fatigue fracture, after the use of wire rope, wear and rust occurred first, wire rope diameter gradually reduced, in the wear of micro-cracks, micro-cracks extended to the wire fatigue fracture occurred, the fatigue fracture needs a longer period of time, usually several months or years, to prevent the wire rope from breaking suddenly. Firstly, the wire rope should not be overloaded during the use. Secondly, the wire rope should be inspected, including wear, broken wire and corrosion, the new rope should be replaced in time when it meets the national standard.

What is the scrap standard for shackles?

1, there is a significant permanent deformation or shaft pin can not rotate freely. 2. The wear of any section of buckle and shaft pin is more than 10% of the original size. 3. Crack in any part of the shackle. 4. Shackles should not be locked. 5, unfastening test is not qualified. The phenomenon of crack in the shackle conforms to Article 3 of the scrap standard, so it should be scrapped.
