Problems solved by technology

Although this reduces the effort for creating the load characteristic curve and the subsequent calculation and storage effort during the interpolation, a precise calculation of the actually engaged load is still disadvantageously impossible and in particular is not taken into account when creating the load characteristic curve Changes or tolerances of nonexistent or unknown crane components

Embodiment Construction

[0017] The embodiments are described below.

[0018] figure 1 with 2 The device for performing the method for limiting the load torque of an engineering vehicle according to the present invention is shown in detail. Similar to the arrangement shown in Figure 3, operating parameters such as pressure, angle, length, configuration, etc. are transferred to both the characteristic curve family and the load table, in which one or more multi-dimensional curve families are stored. In consideration of the calculated total potential energy of the construction vehicle and the unknown load determined thereby figure 2 The characteristic curve family stored therein is adjusted so as to provide a more accurate value of the load actually hung on the engineering vehicle compared to the load value determined by a method known in the prior art. This more accurate load value can be compared with the load limit value, which can either significantly reduce the existing load reserve to a minimum or m...

Abstract

The invention relates to a method for the load torque limitation of a work vehicle comprising a jib, in particular a mobile crane comprising a multi-part, preferably hydraulically movable jib or telescoping jib, wherein on the basis of captured operating parameters of the work vehicle such as pressure, angle, length, configuration and the like from at least one multi-dimensional characteristic map a load value is determined and compared to a load limit value which is determined depending upon the captured operating parameters, wherein a warning is issued and / or the operation of the work vehicle is automatically interrupted when the actual load value exceeds the load limit value, wherein depending upon the captured operating parameters a value for a potential total energy of the work vehicle is calculated, taking into account the configuration of the work vehicle, and the unknown load value is determined on the basis of said value.

Description

Technical field [0001] The present invention relates to a method for limiting the load moment of an engineering vehicle with a boom according to the features of the preamble of claim 1, especially a mobile crane with a multi-piece boom that can be moved hydraulically. Background technique [0002] The methods for limiting the load moment of construction vehicles are basically known, and two different methods in the prior art are described below. [0003] The first method is shown in Figures 3 to 5. Collect the operating parameters of the engineering vehicle such as pressure (for example, in the working cylinder for raising and lowering the boom), angle (of the boom), length (especially of the boom) and other configurations of the truck (for example, The number of telescopic elements of the telescopic boom) and transport it on the one hand to the multidimensional characteristic curve family and on the other hand to the load table with load limit values. From the collected operatin...
