> Connect the pressure gauge to the hydraulic connection.
Above: Example 1 - Ideal case
Below: Example 2 - Complicated case
The two examples in the diagram
illustrate that the centre of gravity can vary depending
on the weight and shape of the load to be lifted.
Calculation of the centre of gravity on the
complicated case (example 2)

JKB revolving transport trolleys / JLF multi-purpose trolleys
Example of a complicated case
> Determine and record the lengths.
> Move the jack so that the load to be lifted is lifted
horizontally over the opposite rotating edge. Use the
jack to raise the load to be lifted to a maximum of
1 mm.
> Determine and record the pressure on all four sides
in the same way.
NOTE
To avoid overloads in the event the centre of gravity is
unknown, a single jack must be able to lift the entire
transport load by itself.
The total weight can exceed the specified total weight
of the original machine (weight on the nameplate) due
to later attachments.
