Shackle Information and How to use Shackle Safely
The most general shackles are including two types:Screw pin shackles and round pin shackles.
Screw pin shackles are used in picking or moving a load and placed as required. Screw pin shackles can used for applications involving side-loading circumstances.
Our T(8)/S(6) shackles made by super alloy steel forged-quenched. The maximum test load is 2 times of the work rated load and the minimum breaking load of four times the rated load.Our products meet the technical requirements and test methods ISO2415-2004 requirements.
12 Rules to use shackles safely
1.Production operations should first check whether there are defects in all shackles, model match, the connection is solid and reliable.
2.Do not use screws or metal rods instead of the pin.
3.The lifting process does not allow a greater impact and collision, should move uniform.
4.In a lifting pin hole should be flexible rotation, not allowed to have jamming phenomenon.
5.Shackles in the body can not withstand the lateral bending moment that should be in the body of the plane carrying capacity.
6.When the plane carrying capacity exists within the body at different angles, shackle the maximum working load too.
7.The maximum angle between the legs carrying shackle rigging shall nor be greater than 120 degrees between the (see below) of the adjustment.
8.Shackle to properly support the load, that is where the role to be along the center line axis of the shackle, avoid bending, unstable loads, but can not overload.(as below)
9.Avoid shackle eccentric load( as below）
10.Shackle in supporting the use of rigging and rope rigging as a bundle, the horizontal part of the shackle pin and grommet should be connected to the rope rigging, to avoid lifting when rigging, wire rope and cable friction buckle, causing cross pin rotation resulting from the cross pin and buckle body( as below)
11.According to the frequency of use, poor working conditions should determine a reasonable degree of periodic inspection, regular inspection period not less than six months and not longer than one year, and make inspection records.
12.The use in high temperature environments, should be considered to reduce the load, as follows
PINTEJIN Rigging lifting sling now has become leading enterprise in China. And we are creating the largest-scale and metal forging workshop.PINTEJIN has the complete production line from raw material to finished products. Each processing has independent workshop, making lifting sling, ratchet strap, car towing belt from 0.5T to 3000T. We are capable of finishing big order quickly.
