Narrow Gauge 14-Ton Underground Trolley Locomotive

Narrow Gauge 14-Ton Underground Trolley Locomotive

What should we do if the air brake of the mining electric locomotive fails?

The first is to check where the problem is, which leads to the failure of the air brake of the mining electric locomotive. The direction of inspection is divided into three parts - mechanical structure and fasteners, pipelines and seals, air brake compressed air motor.

Check whether there is a failure of mechanical parts or loose fasteners that cause transmission failure, or whether the pipeline is damaged or the seal fails to cause air leakage, resulting in insufficient braking force. Or there is a problem with the air compressor, resulting in insufficient pressure.

If the mechanical parts, pipelines, and seals are damaged or invalid, they can be replaced in time. If the fasteners and seals are loose, retighten and seal.

There is a problem with the air compressor, remove it and check the problem. If it is a problem that needs to be replaced such as a brush, it can be solved by yourself. If it is another problem, it is recommended to hand it over to a professional or return it to the factory for repair.

3.Gear anastomosis surface to reach more than 80%, which is far more exceeding the standard.
4.Professionally designed and adjusted frame ensure safe driving and avoids falling off rails.
5.A variety of braking methods can be choose, air brake, hydraulic brake, electric brake, mechanical brake to ensure the safety drive.
6. 40 years richful experience with the ability to design and make customized product according to your requirements.
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.
