Draft Gear

Draft gear is the core of the whole draft system. It is a large heavy component that absorbs the energy of the equipment coupling together. Draft gear provides rebound force that maintains slack between the cars so that the cars can be moved without damaging other components or product installed on wagons.

In order to meet all specific requirements, draft gear was designed in many different versions, like Mark 50, Mark H-50, SL-76,TF880, MT-2,MT-3 etc. to name just a few. Generally, draft gear are interchangeable in accordance with AAR Rule21. 

Rubber Draft Gear

This is an AAR-compliant central draft gear with baffle plates at both ends and interposed with rubber springs vulcanized on the steel plate. The pieces of rubber spring can be adjusted

according to capacity requirement. Draft gear’s capacity is usually between 15KJ - 35 KJ and stroke is between 40 mm and 50 mm. It’s generally used with a small curve radius coupler.

Small capacity and maintainance friendly are obvious advantages of this draft gear, which is widely used in Southeast Asia, Africa and other regions.
