Comparison of the structure, advantages and disadvantages of several trolley wires

Focus on checking the fasteners for looseness, displacement, and wear of plastic parts and moving parts. Check the spring tension. The contact pressure between the collector brushes and the guide rails should maintain a certain pressure. Find problems in a timely manner. 3. Connector: Check at least once a year. Focus on checking whether the fastening bolts, welds, and supports are loose, rusted, or displaced. If any problems are found, handle them in time.

The cold rolled steel sheet is cold-drawn once in the rolling track to ensure the precision of the rail cross-section dimensions, which replaces the unsafe of the angle steel and other conductive methods. The weight is heavy, the indoor slide wire is dirty, and the outdoor ice causes the circuit to be short, which affects the use. Disadvantages, but also has the characteristics of domestic originality, the track unit length of 4 ~ 6m using coupler connector, can be extended to any length as needed.

Ultra high-slip line technology. In the narrow space of the container yard, seamless steel tubes are used, and various structural reinforcement methods are adopted to erect towers with sufficient rigidity and height, and can be applied to the erection of super-high-slip lines. The high-altitude copper trolley wire line technology II has designed a very simple and practical high-altitude copper trolley wire erection technology method for the container site, installation time and conditions are limited.
