Common Notes on Maintenance of Spider Cranes

What are the maintenance precautions for spider cranes? Let’s take a look below.

Carried out by operators as routine maintenance, it mainly includes cleaning, lubricating transmission parts, as well as adjustment and fastening work.Test the sensitivity and reliability of safety devices through trial operation, and check for abnormal operating noises.

Jointly completed by maintenance workers and operators. On the basis of daily inspection, it focuses on visual inspection.Check the safety condition of hooks, lifting attachments and steel wire ropes, and verify the sensitivity and reliability of brakes, clutches and emergency alarm devices.Observe transmission components for abnormal noise and overheating during operation.

Organized by the equipment safety management department and implemented together with relevant staff of the user department.In addition to weekly inspection items, it conducts comprehensive condition detection on the power system, hoisting mechanism, slewing mechanism, traveling mechanism and hydraulic system of the crane.Replace worn, deformed, cracked and corroded parts. For the electrical control system, inspect the reliability of power supply devices, controllers, overload protection and safety protection devices.Check for potential faults caused by leakage, pressure, temperature, vibration and noise through test operation.Perform visual inspection on the overall structure, supports and transmission parts to grasp the technical condition of the whole machine and determine the source of abnormalities.

Led by the equipment safety management department under the organization of company management, and carried out jointly with relevant departments.Besides monthly inspection items, it includes technical parameter testing and reliability tests for lifting machinery.Professional testing instruments are used to detect wear on moving parts and conduct flaw detection on welds of metal structures.Evaluate the overall operating condition of the crane through tests on safety devices and key components, and formulate plans for major overhaul, renovation and equipment renewal.
