Embodiment Construction

[0018] The forklift truck 1 shown in the drawing has a drive motor 2 arranged fixed to the vehicle body for driving one or two axles of a motor vehicle. In the front area of ​​the forklift truck 1 there is a lifting device 3 which is designed as a lifting fork and is held on a column 4 in a height-adjustable manner. The strut 4 can be pivoted between different positions relative to the body by a swivel angle α, wherein the swivel axis in the transverse direction runs adjacent to the underbody of the motor vehicle. The lifting device 3 is held on the column 4 in a height-adjustable manner by means of a suitable adjustment device, in particular via a hydraulically actuatable lifting cylinder, and a maximum lowering and a maximum lifting on the column 4 are possible. Arbitrary adjustment between positions. The adjustment of the swivel angle α takes place independently of the height adjustment of the lifting device 3 .

Abstract

A load-carrying vehicle having a vertically adjustable lifting device for picking up a load, and an acceleration sensor system for measuring the acceleration in at least one direction of movement and having a sensor for ascertaining the picked-up load and having a sensor for ascertaining the lift height of the lifting device are described. Control signals for adjusting at least one power unit in the vehicle which influence the driving condition are generated in a regulating and control unit. The acceleration sensor system is situated on the lifting device.

Description

technical field [0001] The invention relates to a truck, in particular a land transport vehicle such as a forklift, with a height-adjustable lifting device according to the preamble of independent claim 1 . Background technique [0002] DE 103 04 658 A1 describes a land transport vehicle designed as a forklift truck which is equipped with a device for controlling the driving stability in order to reduce the risk of tipping over. For forklift trucks, there is often the problem that there is an increased risk of tipping forward under braking due to the short wheelbase, small track width and high center of gravity when lifting goods And there is a danger of tipping sideways at high cornering speeds. The device for controlling the driving stability disclosed in DE 103 04 658 A1 comprises a sensor device and a control mechanism for detecting vehicle state variables and characteristic variables such as acceleration, received goods and lifting height. Limit values ​​for the permi...
