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
c-
Operating class
This is the operating time per day, on the basis of 250 working days per year.
The lifting machine is considered to be in operation when it is moving; however, it is not considered to be in operation
during downtimes, for example, between lifting and lowering.
These three parameters give the FEM classification for the TRBoxter INOX:
TRBoxter INOX from 250 to 990 kg

WARNING
•
The electronic speed control equipement of the electric motors are connected to potentially dangerous
voltages. When connecting, performing servicing or dismantling these appliances, the greatest of precautions
must be taken to prevent electric discharges.
This appliance contains capacitors which accumulate energy. When the appliance is switched off, these
capacitors retain a dangerous voltage for a few minutes subsequent to switching off. Wait at least 5 minutes
before opening or touching live parts of the appliance.
The earth connection of the appliance must be connected to a suitable earth connector of the electrical
installation.
This appliance must be installed, adjusted and serviced by a qualified electrician. This person must be familiar
with the construction and commissioning of this appliance.
