ENSURING SAFETY & COMFORT IN RAIL TRANSPORT

COUPLERS

AAR-H TYPE COUPLER

Over the past 60 years, Escorts Kubota has been a supplier of advanced coupler systems to Indian Railways for high-speed trains, metros, and EMUs. We also supply high-capacity couplers for locomotives which include GM / EMD Locos and ALCO Locos.

We are one of the largest suppliers of couplers, with 50%+ market share for AAR-H type couplers and about 50% market share for Schaku couplers in Indian market.

SALIENT FEATURES

  • This coupler system offers anti-climb feature for safe journey of passengers in case of any derailment / accident
  • All castings are passed through rigorous RT and MPI testing to filter the finest of the defects and pass only high class materials ensuring to meet high strength requirements

APPLICATION

  • AAR-H Type Couplers with Balanced Draft Gear for high speed trains up to 160 kmph for passenger coaches
  • AAR-H Type Coupler with transition screw for coupling with both Center Buffer Coupler or Hook Type Couplers
  • GM / EMD and ALCO Locomotive couplers can couple with all Passenger Coach, CBCs, Transition Screw Type

APPLICATION

  • Compatible with H and E type Couplers
  • Ensure Coupling even at low coupling speed of 3-5 kmph
  • Increased safety due to vertical interlocking provided between the couplers
  • Improved vertical support for maintaining the desired height of coupler from the rail level

COUPLER FOR LOCOMOTIVES

  • GM/EMD LOCO COUPLER
  • ALCO LOCO COUPLER

Escorts made Loco couplers have been designed with single pin clevis which provides compatibility with both Centre Buffer Couplers and Hook type Couplers. They are designed for a tensile load capacity of up to 400 tons. Hence capable of hauling a rake of 26 coaches.

Semi permanent - EMU's/MEMU's

Provides safe and permanent connection of multiple units. Connection between the couplers is ensured by Adjustable Cup Sleeves, with screw type arrangement.

SALIENT FEATURES

  • Prevents overriding of coaches
  • Draw and buff gear absorbs 8 kJ
  • Rigid and slack free connection
  • Jerk-free start and braking during acceleration and deceleration
Brake System

Application

  • EMU, MEMU and DEMU
  • Any other suburban/mass rapid transport system

Centre buffer coupler - Vande Bharat

This is a jerk - free high tensile center buffer coupler (CBC) with a semi-permanent head and balanced type draft gear. Coupler design also meets the interchangeability requirement from semi-permanent type head to AAR-H type head to facilitate coupling with E or H type couplers. The coupler is ideal for high speed trains above 160 kmph, such as Vande Bharat.

SALIENT FEATURES

  • Lightweight and robust design
  • Jerk free coupler
  • Horizontal articulation (±14°) and Vertical articulation (±6°)
  • Gathering coupling range
    • ± 90 mm Horizontal gathering
    • ± 110 mm Vertical gathering
  • Coupling Speed of 3-5 kmph
  • Balanced Draft Gear Complies with UIC 526, EN 15551 standards
  • Tensile Strength of 1500 kN
  • Compression Strength of 2000 kN
  • Bending Strength of 500 kN
  • Energy Absorption 35 kJ max.

Semi Automatic – Metros

  • The coupling has a generous gathering range because of conical /funnel shaped profile of body and guiding horn on the coupler face. The Coupler head confirms to Type-10 design Horizontal gathering range Up to ±284 mm and Vertical gathering range Up to ±75 mm
  • A rigid connection is formed both vertically and horizontally by the coupler faces and locking system
  • The draw gear arrangement serves to cushion the tensile and compressive loads produced under operation and to absorb the impact forces which are generated by train dynamics
  • Provides the automatic pneumatic connection for BP&MR lines
