An industrial truck having height-adjustable load bearing means, lifting height controls in which a plurality of predetermined lifting heights are saved, a lifting height detection system for the load bearing means that detects an actual value of the lifting height and provides it to the lifting height controls, and a control unit that allows the lifting height of the load bearing means to be manually adjusted at different speeds, wherein the lifting height controls move the load bearing means to one of the predetermined lifting heights when the speed for adjusting the load bearing means specified by the control unit falls below a predetermined threshold, wherein the lifting height assumed by the lifting height controls corresponds to the lifting height of the predetermined lifting heights that most closely approximates the actual value of the lifting height in the direction in which the load bearing means is moving.

Industrial truck with height-adjustable load bearing means

A hand-actuated operating device for an operator's control unit for an industrial truck, having a stationary, raised rest for the ball of the thumb that is disposed laterally beside and in front of the standing or sitting operator, including an upper support area on which the ball of the thumb of the operator's hand is adapted to be placed from top, a forward surface facing away from the operator and a surface facing the operator, wherein the forward and backward surfaces are dimensioned so to allow the support for the ball of the thumb to be gripped between the fingers and a proximal portion of the ball that faces the wrist, a portion located in front of the forward surface which is lowered with respect to the support area is disposed such as to allow the fingers of the hand resting on the support area to be placed at an angle, and at least one control element for a function of the industrial truck is disposed on the end of the lowered portion that is located opposite the support area so as to enable its actuation by at least one finger.
