Suspension Method for Overhead Line of Trolley Locomotive

The suspension of overhead line is the most important step in using mine Trolley Locomotive. Many mine trucks fail in use because this step has not been implemented in the right way. In order to help you know how to suspend the overhead line of the electric locomotive, I specially consulted the technical personnel of the company. Next, please ask him to teach you! Suggest the following content you can read carefully!

1. Hard suspension:
The suspension clamp with porcelain head base is fixed on the steel girder or hardwood crossbar with special Karan, and the ends of the section steel or hardwood crossbar are injected into the upright wall with cement. This Narrow Gauge Locomotive suspension method has strong stability and small protection. But because the overhead line has no elastic buffer, the sliding pantograph exerts greater friction on the overhead line, which shortens the service life of the overhead line.
It is suitable for low roadway, small cross-section area, less driving times, low speed (less than l0km/h), such as locomotive garage line, mobile line, underground through the air door line and so on. At this time, the pantograph of the electric locomotive should be rolled and touched by the contact wheel.

2. Elastic suspension:
It is made of 2-14 galvanized low carbon steel wires with a diameter of 3.2 mm. Two tension insulators are used to insulate overhead wires from roadways. The Narrow Gauge Locomotive overhead wires are clamped with suspension wire clamps. The overhead wires are clamped with ceramic suspensions and suspended on the crosswise suspension wires. The two ends of the horizontal suspension line are hanging on the hook of the suspension line of the roadway wall, and the horizontal suspension line is tightened by a conditioner.
This kind of suspension method, overhead line has certain elasticity, so it is called elastic suspension. Elastic suspension has elastic cushioning effect on overhead line. It can reduce the friction between pantograph and overhead line when touching, and reduce the wear of overhead line. Therefore, Narrow Gauge Locomotive it is widely used above and below the well. The running speed of dry mill is 10-20 km/h. However, due to the elasticity, the overhead line is easy to sway and damage, and the amount of protection T is large. It is suitable for the condition of large cross-section area, high height and bow touch of electric locomotive pantograph.

3. Chain suspension:
This kind of suspension method can adjust tension by human T. The suspension point has elasticity and can be used in the straight line section with more driving times and more driving speed than 20 km/h. This suspension method is generally used on the ground.
