Tight rigging skills
1.Before use chain and load binder, need to see the working load on the plate and the scope of application is prohibited overloading use, and see the chain and load binder, in line with the rear can be used.
2.Under normal use,the load angle of lifting is very important, the maximum angle between the hook and the rigging itself is not allowed to exceed 120 degrees, otherwise it will cause the chain rigging local overload.
3.Prohibit the use of informal links between the chain link.
4.Bearing chain rigging prohibited directly linked to the crane hook components or wound on the hook.
5.The chain tight rigging around the bevel when the object is padded to prevent damage to the ring chain and hanging objects. 6.The temperature for the use of tight rope has a certain impact, between minus 40 degrees to 200 degrees for the rated load, between 200 degrees to 300 degrees when the rated load of 90%, 300 degrees to 400 degrees Between the rated load of 75%, 400 degrees or more is not allowed.
7.Hoisting crane hoisting point requirements and hanging center of gravity in the same plumb line, so that the hoist is in a stable equilibrium, to prevent the sliding or overturning occurs.
8.Do not reverse, twist, tie between chains, and the adjacent chain activities should be flexible.
9.When lifting heavy objects, down, stop to slow and steady, pay attention to be balance the balance of gravity to avoid the impact load, not for a long time hanging heavy objects in the chain.
10. Tight rope to gently, non-beat, touch and drag on the ground, to prevent falling from a height, so as to avoid hanging chain deformation, surface and internal damage.
