Railballast Replenishment Car

I. Product Overview

The Railballast Replenishment Car is a professional rail maintenance equipment independently developed by Yuerui International, designed specifically for the replenishment, distribution, and leveling of ballast in railway track beds. Integrating high-efficiency operation, intelligent control, and multi-scenario adaptation, this product is engineered to address the core needs of ballast management in high-speed railways, conventional railways, and urban rail transit systems. As a key equipment for ensuring track stability and safe train operation, it realizes precise, uniform, and efficient ballast replenishment through advanced structural design and intelligent control technology, effectively extending the service life of track beds and reducing manual maintenance costs, providing reliable support for global railway infrastructure maintenance.

III. Core Advantages

(1) High-Efficiency Operation

Equipped with a large-capacity ballast storage tank, the car can complete continuous replenishment operations for long-distance tracks without frequent refueling, significantly improving construction efficiency. The intelligent distribution system adopts a multi-point uniform feeding design, with adjustable distribution width and flow rate, ensuring that ballast is evenly distributed on the track bed, avoiding local accumulation or insufficient filling. The combination of diesel engine and electric auxiliary drive provides strong power support, enabling stable operation even in complex track sections such as slopes and curves, with a single working efficiency 5 times higher than manual operation.

(2) Precise and Intelligent Control

The dual-control mode of cab manual operation and remote wireless control allows operators to flexibly choose the operation method according to on-site conditions, improving construction flexibility and safety. The cab is equipped with a high-definition display screen that real-time monitors ballast remaining capacity, distribution speed, and operating parameters, enabling precise control of the replenishment process. The intelligent leveling device automatically adjusts the ballast thickness according to the track bed requirements, ensuring consistent ballast density and effectively enhancing track stability and load-bearing capacity.

(3) Strong Adaptability

Adopting a rail-mounted design, the car is perfectly compatible with standard gauge tracks and can be widely used in high-speed railways, conventional railways (adapting to 43kg/m, 50kg/m, 60kg/m rails), and urban rail transit such as subways. The reinforced car body structure is made of high-strength steel, which can withstand the impact of ballast and complex track environments, with strong durability and stability. It is suitable for various working conditions such as outdoor open-air tracks, tunnels, and viaducts, and can operate normally in extreme temperature ranges from -30℃ to 70℃.

(4) Safety and Environmental Protection

The whole machine is equipped with multiple safety protection devices, including overload protection, emergency stop system, and anti-derailment mechanism, comprehensively ensuring the safety of operators and equipment during operation. The diesel engine meets Euro V emission standards, with low noise, low exhaust emissions, and environmental protection performance in line with global railway industry requirements. The closed ballast storage tank and dust suppression device effectively reduce dust pollution during operation, realizing green construction.

IV. Application Scenarios

This equipment is widely used in global railway maintenance and construction projects, including:

• High-speed Railways: Replenishment and maintenance of ballast in track beds of heavy-duty high-precision rails (60kg/m and above), ensuring the stability and smooth operation of high-speed trains;
• Conventional Railways: Daily ballast replenishment, leveling, and replacement of track beds with 43kg/m, 50kg/m, 60kg/m rails, improving track bearing capacity and reducing maintenance frequency;
• Urban Rail Transit: Ballast management of subway and light rail track beds, adapting to the construction needs of complex underground and above-ground environments;
• Railway Renovation Projects: Large-scale ballast replacement and replenishment during track reconstruction and upgrading, helping to improve the overall quality of the track bed.
