Embodiment Construction

[0084] During the lifting process of the crane, in order to prevent accidents such as overturning or bending, it is necessary to estimate the lifting weight of the crane. In the prior art, the hoisting weight detection method adopted by the crane is to detect the boom length, the boom angle and the pressure value of the amplitude oil cylinder, and then calculate the hoisting weight of the crane based on the above values. The problems of the above-mentioned hoisting weight measurement method have been explained in the background technology. At first, the present invention provides a crane hoisting weight measurement method, which provides the basic premise for the crane moment control method described later and constitutes its main difference from the prior art. technical characteristics.

[0085] Please refer to FIG. 1 , which is a flow chart of the method for measuring the hoisting weight of a crane provided by the first embodiment of the present invention. This example will...

Abstract

The present invention discloses a method of measuring the lifted weight of a crane, comprising that: when the crane lifts a heavy article, the borne-force values of each outrigger of the crane are tested and obtained to be added to obtain the total weight of the crane; the self weight of the crane is subtracted from the tested and obtained total weight of the crane to obtain the lifted weight of the crane. The present invention also discloses a method of measuring the balance weight of the crane which has the same technical characteristic as the method. The present invention also discloses a crane moment control method which adopts the method of measuring the lifted weight and a crane moment control system. Compared with the prior art, the method of measuring the lifted weight of the crane provided by the present invention has better testing effect.

Description

technical field [0001] The invention relates to crane technology, in particular to a method for measuring the lifting weight of a crane. The present invention also provides a crane counterweight measuring method using the same inventive concept as the above-mentioned crane hoisting weight measuring method. Using the method for measuring hoisting weight and counterweight, the present invention provides a crane moment control method and a crane moment control system. The present invention also provides a crane with the above-mentioned crane moment control system. Background technique [0002] At present, in order to prevent safety accidents such as overloading and arm folding of cranes and other rotatable construction machinery, most rotatable construction machinery are equipped with torque controllers. The torque controller can analyze the working status of the crane by collecting various detection information distributed in various parts of the construction machinery, and ...
