Commonly used lifting spreaders

Lifting sling refers to the device for lifting heavy objects in hoisting machinery. The most commonly used spreader for lifting items is the hook, and others include rings, lifting suction cups, clamps and forks. It is widely used in the lifting industry.

Metallurgical spreader, steel billet hanger, steel plate hanger, round steel hanger, steel plate hanger clamp, flat sling, flexible sling, sling, wire rope sling, chain sling, hook and various sling accessories. C-type spreader, C-type hook, no-joint rope ring, C-type rolled steel spreader, hanging beam, steel cable lifting net, and can supply hooks, slings, spreaders, slings, fixtures, hangers Rope, lifting chain complete set of rigging.

Steel plate spreader series products: C-shaped coil steel spreader, billet spreader, steel plate lifting clamp, round steel clamp, special spreader for oil drum, turning clamp, horizontal lifting clamp, chain hoist equipment, lifting block.

Suspension series products: Eye Suspenders, Eye Grapples, Swivel Hooks, Claw Sliding Hooks (with Tongue), S Hooks, Nose Hooks, Wire Rope Clamps, Ring Screws, D Shackles, Bow Shackles, etc. .

Rigging series products: one-leg chain rigging, two-leg chain rigging, three-leg chain rigging, four-leg chain rigging, adjustable special sling, chain binding rigging, adjustable roll paper sling rigging, adjustable lashing rigging, double-leg lashing rigging, adjustable four-leg sling (with adjuster), four-prong chain sling set, double-link lifting chain.

Various lifting spreaders use their own structural characteristics and different manufacturing materials to complete different functions.

Maintenance and inspection of wire rope slings

(1) run

The speed of the steel wire rope should be stable during operation, and it should not exceed the load to avoid impact load.

(2) Maintenance

The wire rope has been coated with enough grease during manufacture, but after running, the grease will gradually decrease, and the surface of the wire rope will occupy dirt such as dust and debris, which will cause wear and tear of the wire rope and sheave and rust of the wire rope. Clean and oil. The simple method is to use a wire brush and other corresponding tools to wipe off the dust and other dirt on the surface of the wire rope, apply the heated and melted wire rope surface grease evenly on the surface of the wire rope, or spray No. 30 or No. 40 engine oil on the surface of the wire rope , but do not spray too much and pollute the environment.

(3) Inspection records of wire rope slings

The use of wire rope slings must be regularly checked and recorded. In addition to the above-mentioned cleaning and refueling, the content of regular inspections should also check the degree of wear, broken wires, corrosion of the wire rope, hooks, rings, lubricating wheel grooves, etc. Condition of wear of consumable parts. Any abnormality must be adjusted or replaced in time.

Selection of wire rope slings

(1) Corresponding professional steel wire ropes should be selected for elevator and aviation steel wire ropes

(2) Corresponding special steel wire ropes should be selected for high-lift construction tower cranes, etc.

(3) Steel wire ropes for cranes, piling machines, drilling rigs, electric shovels, excavators and other machinery with low lift require wear resistance, fatigue resistance, and good impact resistance, and structural steel wire ropes such as 6*29Fi or 6*36SW can be used

(4) For equipment operating in high temperature environment or requiring large breaking load, steel wire rope with metal core can be selected

(5) Steel wire ropes for shipping, ships, fisheries, and tying timber are required to be corrosion-resistant and soft, and Class A galvanized steel wire ropes with structures such as 6*19, 6*24, and 6*37 can be used

In addition, the tensile stress of the steel wire rope should be selected according to the load used and the specified safety factor, and the appropriate strength level should be selected, and high strength should not be blindly pursued. In short, according to the characteristics of the equipment and the working situation, the appropriate wire rope should be selected to ensure safety, prolong service life and improve economic benefits.
