3-Ton Narrow Gauge Trolley Locomotive for Mining

3-Ton Narrow Gauge Trolley Locomotive for Mining

What should be paid attention to in the electrical braking of mining electric locomotives?

The braking of mining electric locomotives is divided into mechanical braking and electrical braking. Among them, electric braking is used as an auxiliary braking method, the purpose of which is to improve the braking effect and reduce the loss of mechanical braking. In addition, it is also suitable for speed limit and deceleration during long-distance transportation and long downhill.

Is there anything to pay attention to when using electric brakes for mining electric locomotives?

Because the common electrical braking of mining electric locomotives is to convert excess energy into electrical energy and dissipate it in the form of heat through braking resistors. Therefore, pay attention to the use time when using electric braking. If the time is too long, the braking resistor may overheat and burn out. And the electrical brake is braked through the control of the circuit, so it must be operated in accordance with the operating regulations. Violation of the operation may cause high current to burn out the motor.

7. Proving factory online-visiting

Mining Locomotive test
1.Before Running the locomotive,carry out gear debugging, lighting, gear, and brake adjustment etc.To ensure the normal operation of the locomotive.
2.Carry out a tensile test before leaving the factory to ensure the load performance of the locomotive meets the standard. Our design standards generally exceed the national standard by 10%-20%.
3.Carry out different type running test before leaving the factory to ensure the performance and normal operation of the whole locomotive. It can adapt to various harsh conditions under simulated working conditions.

Motor test
The motor has to go through many inspection procedures before leaving the factory, and each motor has to be carried out with load running experiments.
Explosion-proof motors are carried out with water pressure test.
All the test of motor is to ensure that can adapt to harsh working conditions.

1. A good feedback of our lithium battery locomotive from a client of Latin America
2. In order to solve the exist problems of lead-acid batteries. More than 30 lead-acid battery electric locomotives in this large mining were changed into lithium battery electric locomotives, which improved the work enthusiasm and production efficiency of employees, reduced costs,and more environment-friendly.
3. The mining rock drill car designed by Sunward Co., has a small size and simple structure, so the space for placing the lithium battery on the body is very limited.
According to the limitation size, our company design a lithium power supply power plan, which
perfectly solves the problem of lithium power supply space.
In order to adapt to the special industrial and mining environment and improve transportation efficiency, a batch of 2.5-ton lithium battery electric locomotives are designed to Myanmar Clients.
