The lifting of objects generally occurs on construction sites, in factories,Plant and other industrial situations.

Correct lifting can move large objects efficiently and reduce manual handling operations. Incorrect lifting however, can lead to disastrous accidents.

Every year, incorrect lifting procedures cause injuries, loss of work time and property.

People,machinery, loads, methods and the work environment, are all important factors for correct lifting.

Provided that enough safety measures are fully implemented, lifting accidents can be reduced.

Overview

Definition Rigging & Slinging?

i. Rigging -The process of lifting and moving heavy loads with ropes,

chains, and mechanical devices.

ii. Sling - A loop of material that connects the load to the lifting device.

Slings can be made of chain, wire, metal mesh, natural, and synthetic

materials.

Type of Rigging Gears / Accessories

Lifting gears play an important part in the lifting operation.

Their function is to tie the objects tightly and hang them on the

crane. There is a great variety of lifting gears.

If there is insufficient knowledge or a wrong choice is made, lifting

may fail and accidents may result.

All lifting gears shall be tested by qualified examiners and

suitably marked with a Safe Working Load (SWL).

1. Wire Ropes

wire rope is metal in its strongest form.

It consists of a group of strands laid helically around a core.

The strands of a wire rope, or cable consist of a number of individual

wires laid about a central as shown in Figure 3 (where a : wire, b : strand,

c : centre and d : wire rope).

2. Fibre Rope

Fibre rope is a commonly used tool which has many applications in daily hoisting

and rigging operations.Readily available in a wide variety of synthetic and natural

fibre materials, these ropes may be used as :

(a) slings for hoisting materials

(b) handlines for lifting light loads

(c) taglines for helping to guide and control loads.

3. Synthetic Sling

Synthetic fibre ropes have many advantages over natural fibre ropes

including:

(a) greater strength size for size

(b) lighter weight size for size

(c) greater elasticity or stretch

(d) greater shock absorption because of greater elasticity

Inspection Flat Webbing & Round Synthetic Sling

Synthetic slings must be inspected before each use.

They must also be inspected at least once every three months.

If a sling is subject to severe conditions the inspections should be more frequent.

Send each sling for a proof load test at least every 12 months. Look for:

(a) any external wear such as abrasion or cuts and contusions.

(b) internal wear which is often indicated by a thickening of the sling or the presence of

grit and dirt.

(c) damage to any protective coating of the sling.

(d) damage caused by high temperatures, sunlight or chemicals (indicated by

discolouration).

(e) damage to the label or stitching.

(f) damage to the eyes or any terminal attachments or end fittings.

4. Chain

Wire rope is used more commonly than chain for most construction rigging

operations, even though chain may perform better under certain conditions.

In the past most chain rope was made from wrought iron and mild steel, and

it often failed, causing injury and death. Thus, for rigging purposes the

construction industry has used wire rope almost exclusively.

Chain produced today is superior to that of the past, but the circumstances

of the job may determine whether chain or wire rope should be used.
