HYDRULIC DAMPERS

RED is manufacturing heavy duty Hydraulic dampers for Indian railways since 1962. We are the primary supplier of Hydraulic dampers to the Indian Railways which is one of the most critical components. We have supplied dampers to various international railways such as Egypt, Sri Lanka, Taiwan, Philippines, UK, Tanzania, Iran, Myanmar, and many more. More than 10,00,000 dampers were supplied for various applications across the globe.

Air Spring and Control Equipment

Air spring and control equipment ensures a constant floor height on coaches by optimizing the values of stiffness and dampening the vibration to provide passenger comfort. This equipment is used to control the secondary stage of air suspension.

FAILURE INDICATION AND BRAKE APPLICATION (FIBA) FOR LHB and EMU COACHES

To meet the requirement of a fool proof arrangement in the air suspension design, FIBA is connected with each air spring fitted under the coach. The basic principle in this arrangement is to actuate the application of brakes in the event of air spring failure, which will immediately reduce the speed of the train and ultimately bring the train to a standstill.

SALIENT FEATURES

  • Aluminium Body
  • Compact Design
  • Easy Maintenance
  • Environment Friendly

ADVANTAGES OF FIBA

  • The valve is smaller in size and economical
  • Compact Design
  • Easy to handle due to its smaller size and light weight
  • Compact in size with fewer parts
  • More reliable and less maintenance
