Capacities at alternative load centres
Capacities at Alternative Load Centres
Capacities shown in conventional data sheets are quoted at between
500mm and 1200 mm load centres depending on truck rated capacity.
When longer loads are to be handled, the calculation shown below
may be used as a guide only for truck capacity at
alternative load centres.
- Q = nominal rated capacity (load weight)*
- C = rated load centre
- C2 = new load centre
- Q2 = new residual capacity
- X = axle centre to fork face
Q2= Qx / (x+C)
Rated capacity is reduced as the load centre is increased.
This method of estimating relates only to forward moments of
the truck (and for a reach truck with reach out),
and serves as a guide only.
* This figure may reduce as lift height increases.
It does not follow that greater weight can be handled at load centres less than
quoted; and at high lift the situation may be governed by other factors. Fork stress,
and stress on mast and rollers, must also be taken into account. Consultation may
be necessary to ensure that your truck capacity is correctly assessed for
unusual loading conditions.
Where an attachment is to be fitted to a fork lift truck, the nominal
capacity of the truck will be reduced.
