Maintenance and upkeep of double beam cranes: It is necessary to inspect the brakes of each mechanism, the operation of each mechanism, the tightening of connecting bolts of each component, and the steel wire ropes of each part. If any faults occur, they should be promptly eliminated. The working conditions of connecting bolts, welds, and components of each mechanism should be checked, and they should be tightened and painted regularly. Maintenance and upkeep of the hydraulic system: Add or replace hydraulic oil on time, and check the oil pipes and their joints, safety valves, hydraulic pumps, and hydraulic cylinders. If problems are found, they should be dealt with in a timely manner.

Maintenance and upkeep of the electrical system: wires and cables should be undamaged, the travel switch of the safety device must be reliable, and the grounding protection resistance should meet the requirements. Lubrication work: The lubrication condition of various parts of the tower crane should be regularly checked, periodic lubrication work should be done, and lubricants should be added or replaced on time.

1. Determination of maintenance period for single beam cranes. The maintenance cycle of equipment can be long or short, but some units or individuals do not fully believe in the factory data description of single beam cranes. They rush to carry out maintenance after the new equipment is integrated, completely ignoring the specific usage status of the equipment. Specifically, the different operating conditions and travel lengths used by each part of the mechanism of a single beam crane can serve as a basis for determining its maintenance period.

2. Maintenance issues. Many people have to wait until certain mechanisms of the equipment collapse before repairing when using a single beam crane. As a result, it is easy to have to undergo repair surgery on the collapsed mechanism every once in a while, which undoubtedly increases the cost of equipment maintenance. Therefore, users of single beam cranes must pay attention to timely improvement, adjustment, and repair of every minor issue of the equipment, in order to extend the "collapse" and "repair" period of the equipment mechanism.

3. The problem of using oil. Single beam cranes mostly use hydraulic oil, lubricating oil, fuel and other oil materials, and the use of single beam cranes inevitably requires a lot of costs in terms of oil materials. However, if the issue of fuel consumption of single beam cranes is considered and the factors that increase fuel consumption of single beam cranes are minimized as much as possible, it is believed that the purpose of saving maintenance costs can be achieved in the use of fuel.
