During the trial period of self-china cable durm power rail traveling electric flat carriage delivered to the foundry workshop, several failures occurred. After analysis and summary,

The reasons for the failure are as follows:

 

1. Large dust in the foundry workshop and the accumulation of dust in the sliding contact line, resulting in poor contact between the collector brush and the sliding contact line.Heavy wear of the collector.

 

2. When the forklift is over the sliding contact line, there is often a lot of resin sand falling inside, causing serious wear of the collector.

 

3. When cleaning the workshop, the staff often sweeps into the dirt in the seat of the sliding contact line, and sometimes the people in the sliding contact cause a lot of water, which causes poor contact of the collector.

 

4. Due to the inattention of the ground cattle operators, it is often passed through the lower part of the groove of the sliding contact line.

The wheel often falls into the slot, causing the sliding contact line to be extruded and deformed, causing the collector to stray repeatedly, even.The deformation of the collector bracket is scrapped.

 

5. The casting staff did not clean the accumulated dust in the sliding contact groove every day, causing serious wear and tear of the collector.

 

6. When the operator is operating the flat car, the attention is not focused, and the key switch in the control box is pulled out repeatedly.
