Load Handling
Correct load handling allows the operator to move loads quickly and safely.
WARNING
Handle the load safely at all times. During movements, ensure that the hook,
the load, the product and its moving parts will not collide with objects or
people. Failure to do so could cause death or serious injury.
Evaluating the load
To prevent overloading, the operator shall determine the weight of the load before lifting. The operator shall only lift
the load when he or she is sure that it weighs no more than the permitted load of the product and accessories. The
product’s overload device shall not be used to determine whether the load can be lifted.
Never attempt to lift a load that weighs more than the maximum permitted load of the equipment and accessories.
Balancing the load
The hook, slings and harnesses must be positioned so that the pulling force of the product
lies on the load’s center
of gravity so that the load is balanced. When the operator begins to hoist
a load, he or she shall check that it is
properly balanced before lifting it high off the ground. If the load is not balanced, lower it down and adjust the lifting
point.
1
Lifting centrally balanced loads
The center of gravity will usually be in line with the center of the load.
Provided that the contents of the container cannot move around, the balance of the
load stays the same.
2
Lifting off-center balanced loads
The center of gravity of an off-center balanced load will usually be towards the heavier
end of the load.
Provided that the contents of the container cannot move around, the balance of the
load stays the same.
WARNING
Never try to balance an unbalanced load with your hands. Lower the load and
adjust the lifting point. Trying to balance an unbalanced load with your hands
could cause death or serious injury.
Shock loading
The hoist and accessories are designed to take up the weight of loads gradually and steadily. They are not
designed to withstand sudden increases or decreases in the apparent weight of the load. Shock loading can occur
in any situation where the load on the hoist suddenly increases or decreases. Some examples of how shock
loading can occur are shown in the following text:
