Abstract

In an industrial truck, in particular a fork-lift truck, having a vehicle frame and a load pickup means (16), which can be displaced in relation to the vehicle frame, at least one wheel which is closer to the load pickup means and, at a distance from this, at least one wheel (20) which is further away from the load pickup means being provided on the vehicle frame, the wheel axle (18) of at least one wheel (20) being capable of moving in relation to the vehicle frame along a movement trajectory with a movement component which is orthogonal with respect to the standing area of the industrial truck, in addition a loading force (B), which is caused by the tare weight of the industrial truck and a load (L) which may have been picked up by said industrial truck, acting on the at least one moveable wheel axle (18), which loading force changes operationally, the at least one moveable wheel axle (18) in addition has or can have an arbitrarily variable additional force applied to it.
