GENERAL DATA
Truck Capacities Capacity at different load centres
Note:
4000 The listed capacities are valid only for the standard upright in
3500 vertical position with standard fork carriage and standard forks,
up to max. lifting height of 3300 mm. The centre of gravity of the
Capacity in kg

3000
load may be displaced by max. 100 mm against the longitudinal
2500 S35
centre plane of the truck. Load centre is determined from top and
front face of the forks. The values are based on a 1000 mm cube
2000 S30 load configuration with the centre of gravity at the true centre of
S25
the cube. With upright tilted forward lower capacity values are valid.
1500
S20 Attachments, longer forks, exceptional load dimensions and higher
1000 lifting heights can reduce the capacity.
