2.2 Handling
2.2.1 General instructions concerning handling
Boxes, crates, pallets or cartons may be unloaded
using forklift vehicles or slings dependent on their
size and construction. See 2.3.1 for positioning of
slings.
To lift heavy pieces above 25 kg (55 lb), use a
winch adapted to the mass and in accordance with
the current local regulations.
To lift machines or pieces with one or several sus-
pension rings, only use hooks and chains in com-
pliance with the local regulations concerning
safety. Never put cables, chains or ropes directly
on or in the suspension rings. Cables, chains or lif-
ting ropes must never present excessive bending.
Never bend the lifting hooks, suspension rings,
chains, etc., which should only be made to endure
stresses within, calculated limits. Remember that
the capacity of a lifting device decreases when the
direction of the lifting force direction makes an
angle with the device axis.
To increase the safety and the efficiency of the lif-
ting device, all the lifting elements must be as
perpendicular as possible. If necessary a lifting
beam can be placed between the winch and the
load.
When heavy pieces are lifted up, never stay or
work under the load or in the area, which could be
in the path of the load if it were to swing or fall
away. Never leave a load hanging from a winch.
The acceleration or the slowing-down of lifting
equipment must stay in the safety limits for the
staff.
A winch must be positioned in such a way that the
load will be raised perpendicularly. Where possible
necessary precautions must be taken to avoid the
swing of the load, using for example two winches
making approximately the same angle, below 30°,
with the vertical.
