Cope: day-to-day maintenance knowledge of cranes
Lifting machinery, as a special equipment for handling heavy loads, is an essential material transport equipment for increasing labour productivity and is now widely used in various areas of economic construction。
However, agencies often find themselves in intermittent, circular and repetitive working environments, and there will inevitably be some major and minor malfunctions. In order to ensure the safe operation of cranes, they should be regularly inspected by the user units, including daily, monthly, annual inspections, etc., for the timely handling of anomalies. Let's look at some of the points that have been summed up by the mini-authors of the auto-training。
Normally, the operator can be judged in the course of his or her operation by means of a test, which can be seen, heard, etc. In general, spot checks are performed on power sources, controllers, wire ropes, hooks, etc. Daily spot checks reduce the failure rate by 50 per cent。
This is mainly due to a variety of lubrication efforts. For example, the inspection of connectors, tightening; surface checks of security installations, vulnerable items and electrical equipment are performed by mechanical maintenance personnel. Standard monthly inspections can also reduce the failure rate by 40 per cent。
This involves, inter alia, replacement of equipment, adaptation of protection and major modifications, which require highly specialized knowledge and experience, as well as specialized personnel。
Regular maintenance and maintenance not only prolong the life of cranes but also effectively ensure physical safety. So, how much do you know about cranes while maintaining them
Iv. Information on crane maintenance
• it is prohibited to stand on the main beam when cleaning and cleaning cranes
When maintenance is performed on cranes, it is prohibited to move and test vehicles
During the overhaul, parts and tools that will need to be replaced are not allowed to be placed on the main beam
The electrical inspection and maintenance equipment is not normally allowed, much less the maintenance of the equipment during its operation
In the course of a test drive, brakes with a load to adjust the lifting apparatus are prohibited。
In any case, the maintenance and maintenance of cranes is essential, and it is important that problems be identified and resolved in a timely manner, and that we be contacted in a timely manner if problems are not solved by ourselves
