With the development of the domestic economy, the domestic shipping industry has increased, but the mining and machinery industries are increasingly used for enterprise production, and related enterprises are also increasingly using mechanized equipment such as cranes and hoists. But these devices inevitably require the use of sliding contact wires. This article focuses on how to distinguish the quality of sliding touch lines through visual means such as viewing and touching.

Crane sliding contact line, crane sliding contact line, abbreviated as safety sliding contact line. After more than a decade of development, researchers at home and abroad have conducted statistical analysis on the practical application of sliding wires, and obtained multiple performance indicators of sliding wires. Customers can distinguish the quality of sliding lines based on the comparison of indicators.
The quality of the crane sliding contact line, that is, the sliding contact line, can be maintained unchanged according to the following standards 3360

Firstly, carbon brushes are one of the important components of electric vehicle wires. The service life of carbon brushes is generally short and they are consumables. Its service life is affected by the frequency of use and distance, and the operating distance affects the equipment maintenance cycle. So when using overhead line equipment, strict attention should be paid to the operating distance of the overhead line. Like a locomotive, the general lifespan of the overhead line is proportional to its operating distance. Then observe the appearance of the sliding contact wire. There are various specifications for sliding contact wires, such as ordinary type, anti-corrosion, wear-resistant, high temperature resistant, etc. Everyone must choose a suitable sliding contact wire based on the usage environment of the sliding contact wire. Quality, applicable temperature, environment, etc. The outer layer of the sliding contact wire, such as sunlight, should not be too cold in winter, and should be collected reasonably when not in use for a long time to prevent weathering.

The performance of the sliding contact wire collector mainly comes from the service life of the wheel, the design of the wheel, and whether the collector can be used in various environments. Special attention should be paid to the issues of slopes and downgrades, and the wheel design and collector engagement under different driving routes should be specially handled.

Contact wire deformation, i.e. sliding wire expansion, should be considered when the length exceeds 100m.
During the use of crane sliding wires, attention must be paid to voltage drop, which varies according to the length of various copper bars. Then, appropriate adjustments should be made after installing the crane sliding wires to ensure their normal and efficient use.
