Embodiment Construction

[0088]An embodiment of a loader in the form of a mobile telescopic truck supporting a loader arm protruding towards the front of the vehicle will be described hereinafter. In this configuration, the risk of tipping is manifested in a forward direction about the tipping axis formed by the front wheels of the vehicle. Thus, monitoring and controlling this capsizing risk involves taking into account inertial forces oriented in the forward direction, ie movements involving a significant amount of movement in this direction.

[0089] In loaders of different configurations, the tipping axis can be positioned in different ways. The movement to be considered must then be selected according to the position of this axis.

[0090] refer to figure 1 , a telescopic truck 1 comprises a frame 2 supported on the ground by means of a front axle 3 and a rear axle 4 . Optionally, a stabilizing foot 5 can be deployed for raising the front axle 3, in which case the stabilizing foot 5 defines th...

Abstract

The invention relates to a control method for controlling an actuating device in a loader, the method comprising: comparing (24 ); and depending on the result of said comparison to control the actuating means so as to: perform or maintain (25) the movement of the loading and unloading arm as long as the magnitude indicating that the movement speed is performed or to be performed is less than said threshold value, and as long as it indicates that the movement speed is performed Or the magnitude of the speed of movement to be performed is greater than said threshold, the movement of the loading arm is prevented or stopped (26).

Description

technical field [0001] The present invention relates to the field of handling machines comprising a body, generally intended to be arranged on the ground, at least one handling arm for receiving a payload that must be moved, and actuating means configured to perform movement of the handling arm relative to the body, and The invention particularly relates to mobile loaders. [0002] Such a loader can in particular be produced as a truck with a telescopic boom, a forklift, a lifting crane, a mechanical excavator, a bucket loader or otherwise. Background technique [0003] In the field of loaders, some countries have decided to adopt a standard which imposes specific requirements for manufacturers to observe and control the stability of such loaders during their operation. [0004] The forces that play a role in the stability of a loader in operation involve both gravitational forces, also known as static loads, i.e. the weight of the loader's loading arm, payload, body and / or...
