The correct use of chain slings results in safety for all employees and economical sling life.
Unsafe slinging poses risks,not only to the load and anything in its path if it fails, but also to the crane or lifting machine and the structure from which it is suspended. The sudden release of a load can result in a catastrophic chain of events resulting in loss of life ore serious injury and damage to property. (This means You and Your property)
It is important that all users of lifting tackle be trained in the correct and safe use of lifting tackle. To avoid the possibility of sling failures due to improper handling we offer the following suggestions:
Causes of lifting accidents:
- Lack of knowledge, training and supervision
- Abuse of equipment
- Incorrect use or choice of equipment
- Failure to establish the mass of the load
- Failure to establish the stability of the load
- Failure to inspect equipment for damage before use
- Failure to conduct statutory inspections and maintenance
- Using untested or home-made lifting tackle
- Failure to consult rigging charts, i.e. - important of angles, choker hitches, etc.
The Operator / Slinger
The operator must exercise intelligence, care and common sense in the selection and use of selected slings in accordance with their intended use based on the size and type of load and the environment of the work place.
A well trained operator can prolong the service life of equipment and reduce costs by avoiding the potentially hazardous effects of overloading equipment, operating at excessive speeds, etc. The operator can look for causes and seek corrective actions if danger exists. The operator should co-operate with co-workers and supervisors, not merely for the good of the equipment and the production schedule, but more importantly for the safety of every one concerned.
- Have you the authority to make the lift
- Is the lifting machine of the correct capacity
- Have you selected the correct lifting tackle
- Have you inspected the attachment points
- Have you inspected the lifting tackle
- Have you attached the lifting tackle correctly
- Are you sure and the personnel are well clear of the load before making the trial lift and that all are clear of your intended path of travel
- Trail Lift: To ensure a lever lift, the crane hook should be directly above the center of gravity of the load, when in doubt lift the load just clear of the ground, if the load tilts, land the load and re-position the slings
- Never use chains in which the links are locked, stretched or are without free movement
- Never hammer a chain or hook into position
- Never use a excessively pitted, corroded or worn sling
- Never carry a load on the point of the hook or insert the point into a chain link
- Do not drag the sling from beneath a load
- Do not allow loads to fall on a sling
- Do not cross, kink or knot a sling
