How the maintenance of European cranes can extend the service life. I believe that many units have encountered these problems in the crane maintenance process. Wuxi Shenzhou Lifting Equipment Co., Ltd. is specialized in undertaking maintenance services for various cranes and cranes, and has professional special Equipment construction qualification can guarantee the safety and stability of your equipment.
It is strictly prohibited to work in front of the crane, that is, the center of gravity of the hook shall not exceed the connecting line between the turning center and the grounding center line of the front leg (left and right). When the lifting capacity indicating device cannot work, the lifting capacity should be determined according to the lifting performance table, and the operation behavior of the truck crane should be regulated to ensure safety.
Check whether the crane’s overload protection device, buffer, torque limiter, stopper, anti-reverse device, windproof device and protection device meet the design requirements, whether the operation of these devices is sensitive and reliable, and whether it can send an alarm in time if the specifications are exceeded Signal, whether the power supply running in a dangerous direction can be automatically cut off.
New gantry cranes generally require an operating cycle of about 60 hours, which is stipulated by the manufacturer according to the technical characteristics of the crane at the initial stage of use. In any case, the manufacturer has a warranty period. If the machine breaks down, the manufacturer is responsible for repairing it. Therefore, the machine is overloaded for a long time during operation, leading to frequent early failures of the machine. This not only affected the normal use of the machine and shortened the use cycle of the machine, but also affected the progress of the project because of the damage of the machine. Therefore, full attention should be paid to the use and maintenance of gantry cranes during operation.
Check the condition of the pulley frequently and maintain a proper gap between the pulley and the outer contour of other objects. If the gap is too small, the cover will be worn by the pulleys. If the gap is too large, the wire rope will loosen out of the groove or be clamped between the cover and the rim of the pulley. On the lifting balance beam and the wedge shell exit of the closing mechanism pulley block, it is easy to bite or cut the wire rope. The smoothness of the rounded corners at the wedge shell exit should be checked frequently. If it is rough or sharp edges have been ground, it must be rounded. Refile the corners smoothly.
