Embodiment Construction

[0024] figure 1 An example of a lifting vehicle 1 is shown, in this example a forklift truck, which according to the invention is equipped with a warning device intended to assist the driver in preventing an unintended overturning of the vehicle. The lifting vehicle comprises a mobile chassis, which in this example has double axles 2 on both the front and rear sides. A single wheel in the form of a steer can optionally be mounted centrally at the rear. The vehicle is provided with a mast 3 at the front, on which a lifting device 4 for axial movement is provided, see also figure 2 front view. In this embodiment, the lifting device comprises a fork arrangement with a double fork in the form of two forks adjustable laterally on the fork plate 5 . The fork plate 5 is connected to the output shaft 6 of the hydraulic lift cylinder 7 so that its height is adjustable.

[0025] The mast 3 is tilted about a substantially horizontal tilting axis 8 so that, in addition to having a co...

Abstract

A lifting vehicle comprises a mobile chassis with a tiltable mast (3) and a lifting device (4,5). Alerting means (15,16) are provided for the purpose of monitoring a load on the lifting device as a result of a cargo being carried thereby. The alerting means comprise a first electronic sensor (1 1), which records a cargo weight, and a second electronic sensor (12) which records a cargo moment. Thealerting means (15,16) are provided with automatic calibration means which, when an output signal below a predetermined threshold value is generated by the one sensor (11), sets to zero an output signal differing therefrom from the other sensor (12).

Description

technical field [0001] The present invention relates to a lift vehicle, in particular a forklift, comprising a mobile chassis with a mast, wherein a lifting device is connected to the mast for axial movement and to a hydraulic lift cylinder for performing a substantially vertical displacement, and wherein there is provided Alarm device to monitor the load on the lifting device due to carrying goods. Background technique [0002] Lift vehicles are used in different embodiments of logistics (often simply referred to as material handling) to move goods quickly and efficiently. Lifting vehicles mainly used for heavy goods in this context are forklifts, in which goods weighing several tens of tons can be lifted and shifted with a lifting device provided therein. Lift vehicles include sufficient counterweight to enable carrying such cargo. However, it is extremely important that the cargo does not exceed the specific maximum specified for the vehicle. Shown in the vehicle's car...
