To pick up a load, have a proper position.
This example is worthwhile in everyday life.
I let you try with a package containing 6 bottles of water. (6 x 1,5 liters = 9 kilo)
Instruction for handling, you must :
have your FEET on each opposite side of the charge.
have your CENTRE OF GRAVITY superposed with the one of the load.
have your BACKBONE properly fixed = flat back.
workout your FIGH muscles.
neither flex, not pull on your ARMS.
BREATHE in before each effort.
SLINGING : choice of the kind of sling
To choose the appropriate kind of sling to the manoeuvre to do, you must know the weight of the load.
Sling are in various shapes and out of different materials, we can find sling out of vegetable or synthetic fibres, steel wires, chains, bands which are weaved in synthetic fibres,...
When we use several sling, you have to remember that the bigger the angle formed by the 2 cables is, the weaker the resistance of the sling becomes.
You should try to limit the angle to 90º and on no account go over 120º.
Slinging with 2 sling : choose longer sling to reduse the angle between the 2 cables.
Slinging with 4 sling : only 2 cables out of 4 are carrying.
Besides, a good slinging is composed of accessories such as compensators, shackles, hook for lifting and couples.
Setting up and protection :
Do never cross 2 sling on a hook for lifting.
Do never hang a link of chain on the end of the hook.
Use hook with closing of security.
Do never do knots with cables or chains.
Do never use wet rope.
Always use gloves to handle steel cable.
Protect sling from sharp angles and crushing.
Overestimate the weight of the load to be handled.
Always well balance the load.
Making of sling outof steel cable :
Always strangle the dead part.
And don't forget : carrying well is being well !
