Light
Lifting machines rarely subject to maximum load and
regularly used for very light loads.
k ≤ 0,5
Medium
Lifting machines quite often subject to maximum load
and regularly used for light loads.
0,5 < k ≤ 0,63
Heavy
Lifting machines often subject to maximum load and
regularly used for medium loads.
0,63 < k ≤ 0,8
Very
heavy
Lifting machines regularly subject to loads close to the
maximum load.
0,8 < k ≤ 1
For an exact classification, it is preferable to calculate the average cubic value using the following
formula:
where:
ß
= payload or partial load
rated capacity
t
= operating time with payload or partial load + dead load
total operating time
Y
=
dead load
maximum capacity
t
Δ
= operating time with dead load only
total operating time

7 – Handling - Storage
Important
: the angle formed between the hook and the two sling points
must not exceed 45°.
Lift and place the winch carefully without dropping it.
Do not forget that the centre of gravity of the winch is off-centre.
For more information concerning the weight of the winch, please consult
the Technical specifications chapter.
When stored, these winches must be protected from bad weather in a clean and dry place at a temperature
between -10°C and +50°C.
