Rail Transfer Trolley Fault Emergency Repair Strategy
In the fast pace of industrial production, once transfer trolley on rail breaks down, if it cannot be repaired in time, it will seriously affect the efficiency of material transfer and may even lead to the stagnation of the whole production line. So when transfer trolley on rail ‘temper’, how can maintenance personnel quickly determine the failure point and efficient maintenance?

Fault Judgement for Transfer Trolley on Rail
When transfer trolley on rail does not move, maintenance personnel should observe the control panel to see if there is a fault indicator light, different colours, flashing frequency of the indicator often corresponds to a specific type of failure, such as the red light is always on may imply that the motor is overloaded, the yellow light flashes or perhaps the circuit is short-circuited.
At the same time, listening carefully to the sound of material handling equipment running is also vital; abnormal humming sound may come from the motor bearing wear, and sharp squeaks may be a problem with the brake system. In addition, touch the key components and feel their temperature. If the motor casing is hot, the probability of poor heat dissipation or prolonged overload operation.
Routine Malfunction for Electric Transfer Cart
Take motor failure as an example, if the motor is judged to be burnt, the maintenance personnel need to cut off the power supply first, use professional tools to disassemble the motor, and check the damage of the winding. If the winding is only slightly burnt, can be repaired by re-insulation treatment, replacement of part of the winding line.
If it is seriously burnt, it can only be replaced with a new motor. In the replacement process, in strict accordance with the motor installation instructions, to ensure that the motor installation position, coupling connection accuracy and so on are in line with the requirements of the installation is completed, but also for no-load test run, monitor the current, speed, temperature and other parameters are normal.
