Common synthetic fiber synthetic lifting belt and polyester Small Ratchet Starps/nylon lifting rope can be better than wire rope metal rigging to lift precision items, such as precision instrument accessories, paint plating accessories, electric control equipment and so on…
The hoisting belt structure is composed of (bearing center) parallel arrangement of silk bundles to form a ring sleeve (non-polar winding), and special anti-wear pipe sleeve. Load-bearing wire winding, casing plays a protective role, is the lifting belt to increase the service life.Small Ratchet Starps
The lifting belt is labeled with the working load. In order to prevent the tag from wearing out and the working load is not visible, the lifting belt is also distinguished by color:
1 ton (purple)
2 tons (green)
3 tons (yellow)
4 tons (grey)
5 tons (red)
It’s much more visible and intuitive to use.
Steel plate pliers hoisting pliers inspection test Small Ratchet Starps
(1) Before the test, visually check whether each action of the steel plate lifting clamp is flexible and reliable, and whether all the movable parts are blocked or not.
(2) Static load test, so that the steel plate lifting clamp under 2 times the load of the test force, suspension time should not be less than 3 minutes, after unloading each part should not crack, deformation, coating off or damage to the performance and may have an impact, the deformation of the opening size should not exceed 0.25%;
(3) Dynamic load test, according to the characteristics of different steel plate hoisting pliers, according to the “tightening – dropping – release” sequence cycle, cycle times no less than 5 times (a cycle for 1 time), the load is 1.25 times the load, after the test parts should not wear or other abnormal phenomenon;
(4) Small ultimate strength load, so that the steel plate hoisting pliers bear 4 times the load of the test force, when the prescribed test load, maintain the suspension time is not less than 5 minutes.
