Embodiment Construction

[0027] figure 1 Shown is a working device with a variable working height. This is a crane 1 with an outrigger 2 whose length can be adjusted. The outrigger 2 is movably anchored to the crane 1 with one end thereof, while the front end is placed on the driver's cab of the crane 1 in a freely movable manner. At the end of the jib 2 that is movably connected to the crane 1, a crank device is arranged, by means of which the jib 2 can be raised so that the freely movable end of the jib 2 is released from the driver's cab of the crane 1 . A first control 3 is arranged on the freely movable end of the extension arm 2 . The second controller 4 is located on the base of the boom 2 where the boom 2 is movably connected to the crane 1 . A third control 5 is arranged on a suspension mounted on the freely movable end of the boom 2 .

[0028] All three controllers 3, 4, 5 have a consistent structure which should be aided by figure 2 3 instructions for the controller. The controller ...

Abstract

The invention relates to a method for determining a variable operating height of a tool equipped with a pivoting element wherein a linear movement is performed by a pivoting element (2) of the tool (1) in order to achieve the operating height. In order to enable precise results when determining the operating height even in rough environmental conditions, according to the invention the operating height is determined by identifying a pressure differential (?p) which results from the height difference (?h) covered by the pivoting element (2).

Description

technical field [0001] The invention relates to a method for determining a variable working height of a working device equipped with a pivoting element, in which method a linear movement is carried out by the pivoting element of the crane-like working device in order to reach the working height. The invention also relates to a controller for carrying out the method. Background technique [0002] Work equipment equipped with a pivoting element, such as an excavator with an excavator bucket or a crane with a boom, moves the pivoting element by means of hydraulic cylinders. In order to accurately determine the linear position of the pivot element, a travel measuring device can be arranged on each hydraulic cylinder, which measures the linear movement of the hydraulic cylinder. In the harsh environment of construction machines, such travel measuring devices are subject to heavy contamination, which in turn leads to inaccuracies in measuring the path traveled by the hydraulic cy...
