[Qingdao Rui De Tai Metal]  Do you understand these do not know you OUT!


Some of the major rigging professional terms are as follows:


1 rated lifting capacity: under normal conditions, the spreader is allowed to bear the maximum mass of articles when hanging vertically.

2 limit working load: single-limb sling under normal conditions of use, vertical suspension, allowing the maximum quality of the article.

3 slings: hoisting machinery hanging, moving objects, tied to the load on the items of the flexible parts (including the upper and lower parts)

4 limbs between the angle: Sling lifting objects corresponding to the angle between the two arms presented

5 and plumb line angle: Sling lifting objects, the limb and plumb line formed by the angle.

6 Suspension mode factor: under normal conditions of use, the safe working load and performance of the sling as determined by the suspension mode (the number of limbs of the multi-limb sling, the angle between the limbs and the suspension mode of the single-limb sling) The same single-limb sling limit working load ratio.

7 Safe working load: Sling under the conditions of normal use, by the specific method of hanging to allow the maximum quality.

8 test load (verification force): spreader and rigging Under normal conditions of use, when hanging vertically, verify the spreader or rigging capacity of non-destructive vertical load applied.

9 Minimum breaking force: chain, wire rope, etc. in the static tensile breaking test process can withstand the smallest breaking force

10 Ultimate Ultimate Elongation: The percentage of gauge length chain, the total elongation of the end fittings in the rupture of the ratio of the original length.

11 Nominal sling length: Unused slings in the no-load state, the distance between the upper and lower bearing point.

12 C-shaped hook: C-hooked ends with hooks for counterweight.

13 Clamp spreader: A device that extracts objects by closing the mechanism or friction between the mechanism and the object.

14 End Accessories: Sling main ring, the main ring, connecting ring, the middle ring, the lower part of the generic name

15 Main ring: End fittings that connect directly to the crane hook.

16 Intermediate main ring: A link used to connect two or more sling limbs to the main ring

17 connecting ring: chain installed at the end of the chain, directly or through the middle of the chain will be connected to the chain in the end fittings

18 Intermediate ring: Used as a link between the end fitting and the connecting ring attached to the chain.

19 Lower end: A link, ring eye hook, or other device attached to the sling of the sling (this limb away from the main ring or upper end).

20 eye: Sling at the end of the sling.

21 hard eye: set the rigging collar of the cable eye.

22 soft cable eye: not inlaid rigging collar of the cable eye.

23 inserted through: Each rope unit according to the prescribed method, inserted through the gap between the rope out once.

24 Seams: Stitched and fixed connections where the stitches are thread-formed through the web when the end of the webbing is joined to itself or to several layers of webbing.

25 Non-load-bearing seams: Seams that join several layers of webbing without affecting the strength of the harness.

26 Seams to be sewn: seams that form sockeye eyes at the ends of the webbing, as well as the seams on the sling to the head when they are stitched and sewn, which directly absorb the load and affect the strength of the sling.

27 Ring Sling: An endless loop formed by a chain or rope (including fiber ribbon) connected at both ends.

28 Inner length of the link: Pitch of the chain.
