Abstract

The invention discloses a crawler crane installation torque control method, a crawler crane installation torque control device and a crawler crane. The torque control method comprises the following steps of: acquiring a tilting torque and a hoisting weight under a crawler crane installation working condition; comparing the tilting torque with the maximum preset stable torque and comparing the hoisting weight with the maximum preset hoisting weight; and outputting different indication information according to comparison results. The invention has the advantages that: torque security during hoisting can be guaranteed and an aim that a mast has a higher secure working range at light loads can be fulfilled.

Description

technical field [0001] The invention relates to a method and a device for controlling moment of crawler crane installation and the crawler crane. Background technique [0002] At this stage, the moment limiters of all crawler cranes at home and abroad only calculate and limit the moment under working conditions, and do not calculate the moment during installation conditions. Under the installation conditions, it depends entirely on the operation The operator judges whether it is safe and does not tip over based on experience, and careless operation when hoisting the track will lead to a safety tipping accident. In view of the safety needs, the products of individual companies have considered this. A safety limit switch is installed at the maximum safe angle in front of the mast to ensure that when the crane is installed, the mast can only work at a safe angle under the maximum lifting condition of the hoisting cylinder. , thus greatly sacrificing the light-load hoisting ran...
