Maintenance And Repair Of Crane Electrical System
Mar 27, 2022
Clean up the dust and dirt on the electrical equipment in time to ensure the cleanliness of all distribution boxes, control boxes, brushes and their contact surfaces; always check all cables and wires for damage, if any damage is found, it should be wrapped or Replace; ensure reliable opening and closing of the contacts of the travel switches of each safety device, and the contact arc craters should be polished in time; check whether the crane power supply and each mechanism are provided with short-circuit protection, loss-of-voltage protection, zero-position protection, over-current protection and special cranes. Overspeed, loss of magnetism protection.
Maintenance and repair of safety protection devices
Check whether the installation of overload protection device, buffer, moment limiter, limit position limiter, anti-overturning device, windproof device, and protective device of the crane meets the design requirements, whether the operation of these devices is sensitive and reliable, and whether it can be Send out an alarm signal in time, whether it can automatically cut off the power source running in the dangerous direction.
In short, in the use of cranes, it is necessary to prevent accidental damage, especially abnormal damage caused by human beings, and try to avoid equipment failures. This requires the user to establish and improve scientific and reasonable rules and regulations, strictly implement the technical regulations, take strict precautions against various possible failures, and take effective solutions to the problems that have occurred.
On the one hand, operators must carefully abide by the safety operation procedures and relevant safety systems, so as to ensure safe production and no mechanical accidents; Adjustment, replacement, etc., so that the crane equipment is always in a good technical state, to ensure that various work performance indicators meet the specified requirements. Only in this way can the integrity rate, utilization rate and utilization rate of crane equipment be better improved.
