Product Overview
A ballast plow, also known as a railway ballast leveler, is a type of engineering machinery specifically designed for railway track maintenance. Its main function is to push and level the ballast (crushed stone) under the track to restore its elasticity and load-bearing capacity, ensuring the accuracy of track geometry and enabling smooth train operation. It typically consists of a frame, a liftable central plow, and a side plow. It efficiently pushes the ballast to the sides of the sleepers (or bases), ensuring even thickness and distribution, and clears soil and debris from the track bed.
Key Features
High efficiency:
Processes multiple track sections at once, significantly shortening maintenance time and increasing efficiency by several to dozens of times compared to manual labor.
Precise tamping:
Enables fine-tuning of the track to achieve ideal ballast density and track geometry.
Improved drainage:
Tamping creates gaps between sleepers and ballast, facilitating rapid rainwater drainage and preventing waterlogging from affecting the subgrade strength.
Enhanced stability:
Tightly bonding the ballast effectively distributes train loads, preventing track subsidence or displacement and ensuring a smooth track.
Reduced noise and vibration:
The tamped ballast layer absorbs vibrations and noise generated by train operation, improving the riding experience.
High adaptability:
Suitable for maintenance of various types of lines, such as busy trunk lines and passenger dedicated lines.
Application Scope
Leveling and Shaping:
The central and side plows (with height-adjustable plow blades) push the ballast to the desired position, creating a uniform track bed cross-section.
Restoring Performance:
Once ballast is compacted or mixed with soil, its elasticity decreases. The ballast plow restores its good drainage and shock absorption properties.
Complementary functions:
Often used in conjunction with ballast cleaning and screening machines, the machine removes dirty ballast, suitable ballast is backfilled, new ballast is added, and the ballast plow handles final leveling.
FAQ
Q: What types of railway lines are ballast plows suitable for?
A: This series of ballast plows is designed specifically for standard gauge railways and is suitable for routine maintenance work on ballasted tracks. Specific compatibility needs to be confirmed based on your line's grade (e.g., heavy-haul, conventional, or high-speed railway maintenance access line), sleeper type (concrete or wooden sleepers), and minimum curve radius, among other parameters. Please provide your line's technical specifications, and we will recommend the most suitable model for you.
Q: Can the overall structure withstand long-term high-intensity operation?
A: The main structure adopts a box girder design. Finite element analysis (FEA) and fatigue testing have been performed on key load-bearing components to ensure excellent torsional and bending resistance under rated load. Major welded parts are inspected using flaw detection, and structural strength calculations are provided for reference. The design safety factor is no less than the industry standard requirements.
