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.

RECONDITIONABLE
Designed for easy and trouble free maintenance and can be reconditioned on site. We have assisted many railways in setting up reconditioning shops.
Escorts also supplies complete kits for reconditioning of Hydraulic Dampers including Testing Equipment, Tooling and Fixtures required for reconditioning.
FAILURE INDICATION AND BRAKE APPLICATION LHB ALSTOM 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
- The valve is machined from aluminium block and light weight
- Easy to handle due to its smaller size and light weight
- Compact in size with less no. of parts
- More reliable and less maintenance
AIR SPRING AND CONTROL EQUIPMENT
Air spring and control equipment ensures a constant floor height on coaches by optimizing the values of stiffness and damping the vibration to provide passengers comfort.
SALIENT FEATURES
- Provides more passenger comfort
- Optimised value of stiffness
- Damps the vibration during train movement
- Maintains gap between frame and bogie bolster
APPLICATION
- EMU / DEMU Trains
- High-Speed Passenger Trains
- Metros
SILENT BLOCK
Silent Block provides an interface between two parts, damping the energy transmitted through it, rubber separates the faces of two metal objects while allowing a certain amount of movement and directly affects the safety and comfort of drive. Rubber is a visco-elastic material, it acts as a liquid to absorb shock and as an elastic solid when at rest. It performs by converting the impact of the shock energy to a small amount of heat.
