Abstract

The invention provides a control method for a crane, a moment limiter and a crane, and belongs to the field of cranes. The method comprises the following steps of determining a preset track selected by an operator, wherein the preset track comprises an operation step for controlling the crane; controlling the crane according to the current running data of the crane and the preset track to controlthe crane to operate according to the operation steps in the preset track. The method has the following advantages that manual repeated operation of the operator can be avoided for a specific hoistingworking condition, in particularly the hoisting working condition of the operation track is not changed, time and labor are saved, and more accurate is achieved, so that potential safety hazards caused by manual operation can be reduced; and the control precision of the crane is improved.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a control method for a crane, a moment limiter and the crane. Background technique [0002] In the prior art, when the crane is running, the operator needs to manually control the telescopic, luffing, hoisting, turning and other actions of the crane to meet certain hoisting requirements. For specific hoisting conditions, the operator needs to manually repeat the operation over and over again, which consumes high time and labor costs. In addition, during manual operation, relatively small and fine movements are often difficult to control. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a control method for a crane, a moment limiter and the crane, which are used to solve or at least partly solve the above technical problems. [0004] In order to achieve the above object, an embodiment of the present invention provides a control meth...
