The AGICO Rail Tamping Machine is an indispensable, precision core piece of equipment in modern railway track construction and maintenance operations. Under the combined effects of long-term high-speed train operation, natural environmental changes, and natural ballast settlement, railway tracks inevitably develop geometric deviations—such as irregularities in longitudinal level, alignment, and cross-level. These deviations not only affect the smoothness of train operation and passenger comfort but also pose significant safety hazards. The core mission of AGICO's Tamping Machine is to efficiently restore the track's design smoothness and geometric parameters through automated, high-precision operation.

Our railroad tamping machine utilizes advanced hydraulic vibration and squeezing technology, simulating and surpassing the principles of manual tamping. During operation, pairs of tamping tines accurately insert into the ballast on both sides of the sleeper. High-frequency vibration fluidizes the ballast stones, followed by the application of immense inward squeezing force to rearrange and densely compact the ballast beneath and around the sleeper. This process firmly lifts and stabilizes the rail and sleeper, providing a solid, uniform support foundation for the steel artery. Whether for the final profiling of new lines or the periodic maintenance and overhaul of existing tracks, the AGICO Tamping Machine is a key technological asset for ensuring line quality, extending maintenance cycles, and enhancing operational safety.

AGICO Railroad Ballast Tamper Models

YD-22 Hydraulic Diesel Tamping Machine

This is an efficient and reliable basic hydraulic tamping model. It uses a water-cooled diesel engine for robust power. Its double-guide-column frame and single-cylinder lifting structure ensure stability during tamping, with tines penetrating 110mm beneath the sleeper for compaction. Equipped with a swing-type walking frame for easy lateral movement on the track, it is suitable for routine tamping on various concrete and steel sleeper lines.

 

YD-22II Hydraulic Rail Tamping Machine (Petrol)

As the petrol-powered version of the YD-22, it features optimized upgrades in structure. It employs a double-guide-column frame with a dual-cylinder lifting system for more stable vertical motion of the tamping unit under continuous vibration. The hydraulic system uses crimped hose fittings with an enlarged diameter, reducing oil flow resistance and improving efficiency. Its automatic rail clamping function simplifies operation, making it a high-performance tamper for standard gauge lines.

 

YD-22III Smart Hydraulic Rail Tamping Machine Unit

This is the third-generation intelligent model of the YD-22 series, representing the advanced level of AGICO tampers. Its key feature is the remote-controlled travel frame and electronic control system (including electric start and remote functions), enabling automatic travel and remote operation, significantly boosting work efficiency and safety. While retaining the reliable tamping mechanism of its predecessors, it adds safety features like night work lights and protective mesh guards. Available with diesel or petrol engine options, it flexibly handles demanding maintenance and new line construction tasks.

 

ND-4.2×4 Flexible Shaft Rail Tamping Machine

This model features a unique flexible shaft drive design. A single engine simultaneously drives four tamping picks, enabling dual-operator协同 work, achieving an efficiency of 240-320 sleepers per hour on one rail. The entire machine is lightweight with traveling wheels for quick on/off track movement and relocation. With a low failure rate and easy maintenance, it is an ideal choice for maintenance teams seeking high cost-effectiveness and high mobility.

 

YCD-32 Hydraulic Rail Switch / Turnout Tamping Machine

This is specialized equipment designed to solve the difficult tamping problem in turnout areas. Turnouts have complex structures where standard tampers struggle to operate. The YCD-32 can move flexibly left and right within the turnout area, effectively tamping key sections like switch points, frogs, and guard rails. Its lightweight structure and simple operation make it essential machinery for ensuring track stability in turnout zones.

 

DG-550×4 Electric Rail Tamping Machine Unit

This is an electric tamping solution powered by a generator set. One generator set supplies power to four independent electric tamping picks, each weighing only 26.5 kg for easy carrying. The entire unit can move freely on the track, featuring a compact and adaptable structure. It produces zero on-site emissions and low noise, making it particularly suitable for environmentally sensitive areas like tunnels and urban settings, or locations with power access.
