Observe the details on the maximum
load capacity of the individual fastening
points. In the event of full braking, forces
act that can be many times higher than
the weight of the load being transported.
·
Always use multiple fastening points in
order to distribute absorption of these
forces and to ensure equal stress on
each fastening point.
