Principle

A damper is a device that provides resistance to movement and consumes movement energy. Dowty Retarder is also a kind of damper, which is widely used in railway traffic.

TDJT-101 type dowty retarder is a hydraulic device that does not require external energy and can stop and prevent rolling of railway vehicles.

The dowty retarder detection device uses a digital servo control system (Figure 2), uses a single-chip closed-loop control to load and collect data, and uses a hydraulic device to simulate the force a

The overhead mine electric locomotives uses the pantograph to obtain electrical energy from the circuit.

Mine wagon machinery is a typical existence in the machinery and equipment market today. It is the key to improving mining production efficiency.

Dowty retarder is an independent closed hydraulic unit, which can automatically control the rolling speed of the vehicle without any external energy. The different speed of rolling makes the sliding c
