May 22, 2019
The quality of electric overhead crane sliding wire can be measured according to the following criteria:
1. Carbon brush life: carbon brushes are consumables, driving distance affects its maintenance cycle.

2. Sliding wire shell quality: must meet the temperature, environment and other requirement of electric overhead crane.

3. Collector performance: mainly consider the wheel life, turning wheel design and collectors to meet the use of various environments.

4. Sliding contact line expansion problem: the sliding contact line should consider the expansion problem if with a length of more than 100meters .

5. Voltage drop problem: according to the length of the copper strip, the voltage drop is different.
