Problems with crane main beams have long been a major headache in the lifting industry. How to better correct crane main beam deformation? Taking European-style cranes as an example, this article analyzes the main correction methods and procedures.
When correcting crane main beams, the selection of correction method is extremely important. It not only determines the final correction effect, but also affects the correction cost and operational safety. Therefore, it is necessary to master the characteristics and applicable scope of various methods and select the most appropriate solution according to actual working conditions.
It is also essential to take into account the main causes of main beam deformation. Whether the deformation is caused by residual internal stress generated during welding or by improper operation during transportation and installation, the corresponding correction methods vary accordingly.
After the correction of the European-style crane main beam, a comprehensive inspection must be carried out to ensure the equipment is qualified before putting it into service. During the operation of European-style cranes, all aspects must be effectively controlled to ensure safe and stable lifting operations.
Different types of cranes have different control requirements. What are the corresponding control specifications for overhead cranes?
The system control of European-style cranes covers multiple functions, including the traveling direction and speed gears of the main trolley (left and right movement), the traveling direction and speed gears of the auxiliary trolley (forward and backward movement), as well as the lifting direction and speed gears of the hook. All functions are realized through frequency converters and programmable logic controllers.
