CHANGING THE DIMENSIONS OF THE LOAD SPACE OF A WORKING MACHINE

摘要

Apparatus and method for changing one or several dimensions (Xi, Yi, Zi) of a load space in a working machine, when the dimensions are width (Xi), height (Zi) or length (Yi). In the method the weight (Mi) of the load in the load space is determined or the weight of the load in a full load space is predicted on the basis of said determination and the cur­rent value (Xi, Yi, Zi) of the dimension; a new value (Xi', Yi', Zi') is cal­culated for the dimension by means of which it is possible to reach a set maximum quantity (Mmax) for the part of the weight of the load; and the dimension (Xi, Yi, Zi) of the load space is adjusted either gradually or at once to a position according to the new value (Xi', Yi', Zi'). In the method for changing the height (Zi) of the load space the quantity of the load or a change in the quantity of the load in the load space is determined automatically; and the current height (Zi) of the load space is adjusted to a new height (Zi') or in accordance with a predetermined change of height that corresponds to the quantity of load according to a set dependency, wherein the height of the load space is at the same time kept as low as possible during the loading or unloading.
