Railway Buffer Stop
Railway buffer stop, or railway car stopper, is a safety device fitted at the terminus of all railway stub tracks to prevent rail vehicles from overrunning the track end. It is a vital component of railway transport, ensuring rail vehicles stop safely. In addition, railway buffer stops are widely used in many fields including construction, machinery, railways, crane, steel, power plants, ports, metallurgy and chemical industries. We specialize in manufacturing a full range of railway buffer stops, including sliding, spring buffer and hydraulic buffer types. And we can provide product redesign, modification and customization in accordance with client requirements to fit diverse operating conditions. All our products are manufactured in compliance with ISO9001:2000, and they undergo rigorous inspections as required, deliver reliable and consistent quality, and earn high acclaim among overseas clients. If you have any needs, feel free to contact us.
The Safety Role of Railway Buffer Stop
Buffer stops serve a critical safety function for track users and train passengers. They are widely deployed at railway crossings, especially busy crossings, high-speed rail lines and crossings near densely populated areas. They help reduce railway accidents and keep traffic running safely and smoothly.
Types of Our Railway Buffer Stop
1. Fixed Buffer Stop:
Structure:
It mainly consists of a stop base, buffer head, braking rail and other components.
Installation:
It is secured to the rails on railway terminal tracks via anchor bolts and other fasteners.
Application:
It is suitable for conditions requiring low vehicle stopping capacity and low line speeds.
2. Sliding Buffer Stop
Structure:
It consists of a main frame, braking rails, buffer unit, sliding mechanism and other components.
Working Principle:
When a vehicle impacts the buffer stop, the main frame slides along the rails, and the buffer unit dissipates energy.
Application:
It is suitable for higher-speed railway lines and can better distribute impact loads.
3. Hydraulic Buffer Stop
Structure:
It consists of a hydraulic cylinder, piston rod, buffer pad, control system and other components.
Working Principle:
The hydraulic system provides strong resistance to stop vehicles. When a vehicle impacts the buffer stop, pressure inside the hydraulic cylinder rises quickly and generates stopping force.
Application:
It is suitable for conditions requiring high stopping precision and high stopping force, such as high-speed railway lines.
4. Fixed Hydraulic Buffer Stop
It is a simplified version of the sliding hydraulic buffer stop. It can effectively protect the coupler and absorbs part of the vehicle’s kinetic energy. Application: It is suitable for conditions with no sliding travel, small train consists, and low impact speeds. In addition, the hydraulic buffer’s capacity can be designed for customer requirements. Where necessary, a concrete retaining wall with foundation should be provided.
Structure and Working Principle of Our Railway Buffer Stop
1. Rubber Buffer Pad
Rubber buffer pad
2. Impact Load Transmission
The impact load acts on the rubber buffer pad, passes through the left and right support arms of the support base, and is transferred to the braking rails.
3. Friction Stopping Mechanism
The braking rail and spring seat develop frictional resistance against the basic rail, to stop the vehicle from sliding.
4. Elastic Loading Unit
It is an elastic loading device composed of plate springs, spring seats, wedges and bearing supports; and it is mounted within the main frame braking rails and booster braking rail. It creates preload under static conditions, increases frictional resistance during braking, and maintains continuous braking force under dynamic conditions until the vehicle comes to a halt.
5. Main Frame Structure
The support plate is fabricated from solid plate, and it connects closely with the support base, front and rear cross beams, and upper and lower inclined beams to form the main frame. It features a rational structure and high overall strength, and is able to withstand vehicle impacts at relatively high speeds.
6. Installation & Reset Design
The support plate uses its lower shoe block to slide directly into the braking rail, and it features a simple structure, allowing easy installation, maintenance and reset.
Benefits of Our Railway Buffer Stop
1. Wide Track Compatibility
It features a rational structure, delivers high reliability, and adapts to the terminal ends of dead-end tracks for various rail types and sleepers.
2. Three-Stage Braking Performance
It delivers strong braking capacity, provides impact buffering, and reduces shock loads during vehicle impact. It features an elastic damping device; it creates three-stage braking action to bring runaway vehicles to a halt. And it prevents or minimizes accident damage when runaway vehicles strike the buffer stop.
3. Self-Powered, Easy Track Mounting
It requires no external power, needs no manual control or separate foundation fittings, and it can be mounted directly on the track’s main rails.
4. Easy Installation & Servicing
It delivers simple installation, requires fewer man-hours, enables fast construction, and allows convenient maintenance.
