Modernized Electric Ballast Tamper SVE-2: Reliability and Efficiency
The SVE-2 electric ballast tamper, developed and manufactured by the Kubanzheldormash plant, is a modern, high-performance machine designed for precise and reliable compaction of ballast beneath railway sleepers. It represents an enhanced and updated version of earlier models, specifically adapted for the demanding requirements of track construction, repair, and routine maintenance.
Advantages of the SVE-2
Effective Ballast Compaction
The SVE-2 delivers dense, consistent compaction of crushed stone ballast, ensuring greater sleeper stability and reducing the occurrence of track defects such as settlement, misalignment, or uneven wear. This directly enhances both track longevity and operational safety — essential factors in modern rail infrastructure.
Comfortable and User-Friendly Operation
Designed with ergonomics and usability in mind, the SVE-2 features a compact, well-balanced chassis that minimizes physical strain on the operator. Unlike improvised systems that rely on generic construction-site vibrators, the unit incorporates a dedicated high-performance vibration system, specifically engineered for track work. This minimizes harmful vibration exposure, reduces operator fatigue, and significantly improves compaction precision during prolonged use.
Robust and Durable Construction
The tamper’s housing is produced using a KURTZ low-pressure casting machine, a method that ensures a dense, defect-free microstructure, free from gas porosity or internal flaws. This results in exceptional mechanical strength and extended component lifespan under real-world operating conditions.
Motors within the unit are equipped with high-cross-section copper windings, which provide enhanced resistance to overheating and significantly increase long-term operational stability.
All working components are manufactured from high-strength alloy structural steel, followed by cementation heat treatment — a proven method to ensure wear resistance, even under intense mechanical stress and in abrasive environments.
Versatility Across Conditions
The SVE-2 is designed to work seamlessly with a wide range of sleeper designs and ballast types — from coarse crushed stone to finer gravel mixes. This makes it equally suitable for routine maintenance operations and large-scale infrastructure projects, offering the flexibility required by modern railway services.
