Hand Brake Set for LHB Power Car Coach

The Hand Brake Assembly is a vital safety-critical mechanical apparatus engineered for high-speed LHB passenger stock running on the Indian Railways network. Positioned within the onboard brake panel cabin or end-wall layout of the coach, this assembly functions as an independent, manually operated auxiliary parking brake system. It allows rail operators to secure the vehicle and maintain absolute zero-movement stabilization without relying on active pneumatic pressure from the main brake pipe (BP) or feed pipe (FP) systems.

"Highly accurate Railway Components, such as these metal centering discs for rail bogie systems, showcase a specialized Brake Head attachment featuring precise circular machining.

Centering Discs

Precision-machined for LHB passenger coaches, our Centering Discs are high-strength stabilizing components designed for Indian Railways’ FIAT bogies. Cast from premium Spheroidal Graphite Cast Iron (SGCI) or high-grade cast steel, these discs securely anchor and guide primary and secondary coil suspension springs. They are engineered to absorb intense vertical, lateral, and longitudinal forces during high-speed transit while meeting strict RDSO and RCF specifications. By preventing spring displacement and integrating seamlessly with rubber bump stops, these discs dampen track vibrations, minimize wheel wear, and ensure ultimate passenger safety and ride comfort at operating speeds up to 160 km/h.

A high-performance Railway Components solution, this stiffer cam shaft features a blackened finish and is designed as a critical Control Arm auxiliary component for engine timing and mechanical reliability.

Stiffer Cam Shaft

The Stiffer Camshaft Assembly is a high-integrity, safety-critical mechanical management component engineered exclusively for heavy-duty rolling stock, traction control gearboxes, and auxiliary power systems within the Indian Railways network. Positioned within high-vibration, high-load mechanical environments, this specialized camshaft features an amplified structural cross-section. By completely eliminating the torsional twisting, bowing, and structural bending common in standard shafts, it ensures micro-second precise mechanical timing and reliable long-term performance under maximum hauling demands.

A heavy-duty forged steel Control Arm designed for Railway Components and suspension systems, featuring reinforced pivot points for maximum durability and high-capacity load bearing.

Control Arm

The Control Arm Assembly is a safety-critical structural alignment and suspension component engineered exclusively for the heavy-duty Co-Co bogie configurations of Indian Railways locomotives. Operating as a critical link within the primary suspension and traction gear layout, this high-tensile component connects the axle box housing or bogie frame to secondary stabilization elements. By enforcing rigid geometric alignment while allowing controlled pivoting movement, the control arm prevents excessive lateral or longitudinal axle shifting, ensuring optimal track tracking and vehicle stability under massive tractive loads.

A matched set of industrial-grade pins and bushes with a blue-tempered finish, essential for the high-wear joints of various Railway Components.

Set of Pins and Bushes

The Manganese Steel Pin and Bushes is a safety-critical, high-impact structural pivot kit engineered explicitly for the heavy-duty bogie suspension and traction link mechanisms of three-phase electric locomotives on the Indian Railways network. Operating in an environment subjected to continuous mechanical torque and horizontal tractive forces, this kit serves as the primary pivoting joint for traction rods and link assemblies. It ensures zero structural slack, maintains rigid geometric spacing, and eliminates high-tempo wheel-truck vibrations during heavy freight hauling or high-speed passenger transit.

Brake Gear Arrangement for WAG-9/WAP-7 locomotive

Brake Gear Arrangement for WAG-9/WAP-7 locomotives features TBU/PBU assemblies with brake cylinders, levers, and rigging that transmit 260 kN (WAG-9) or 182 kN (WAP-7) braking force via bogie frames. It integrates regenerative, automatic train, direct loco, parking, and anti-spin brakes for heavy freight (WAG-9) or high-speed passenger (WAP-7) operations. This setup ensures efficient force distribution, minimal hanger failures, and reliable stopping under dynamic loads.

A specialized cast steel Brake Head component, featuring precision-machined pivot points for locomotive braking systems

Brake Head

The Locomotive Brake Head Assembly is a safety-critical, high-impact mechanical component engineered exclusively for the under-slung Co-Co bogie brake rigging layout of heavy-duty electric and diesel locomotives (including the WAG-9, WAG-9HC, and WAP-7 platforms). Operating as the pivotal link between the pneumatic brake rigging beams and the wheel tread, this precision-machined component serves as a rigid backing shoe. It ensures that high-tonnage deceleration forces are applied completely symmetrically across the wheel perimeter, eliminating localized hot spots and maintaining stable brake block friction.
