An Efficient and Precise Compaction Solution for Railway Maintenance

Double-Headed Tamper: An Efficient and Precise Compaction Solution for Railway Maintenance

In railway construction and maintenance, the uniformity and density of ballast are crucial for ensuring track stability and traffic safety. Especially after sleeper replacement, efficiently and effectively completing ballast compaction is a key focus for teams. Shandong Tiannuo Construction Machinery Co., Ltd.'s Double-Headed Tamper, with its innovative design and reliable performance, has become an indispensable piece of professional equipment in railway maintenance projects worldwide.

I. Double-Headed Tamper: Designed for Efficient Railway Maintenance

The Double-Headed Tamper is a hydraulic vibratory device used for railway track bed compaction, primarily for ballast compaction after sleeper replacement. It rearranges and compacts ballast particles through high-frequency vibration, thereby improving the overall stability and load-bearing capacity of the track. This equipment is suitable for standard gauge (1435mm) and broad gauge (1520mm) tracks and can be used with 12-18 ton mainframes. It is widely used in the construction, maintenance, and renovation of railway lines both domestically and internationally.

Compared to traditional manual compaction or single-head tamping equipment, double-head tamping machines offer the following significant advantages:

High operating efficiency: Equipped with 8 tamping picks, both heads operate simultaneously, significantly shortening maintenance time.

Strong adaptability: Supports 360° omnidirectional rotation and adjustable leg angle, adapting to complex tracks and operating environments.

Excellent compaction effect: Vibration frequency reaches 40Hz, with a maximum tamping depth of 400mm, ensuring uniform and dense track bed compaction.

II. Core Parameter Analysis: Guarantee of Performance and Reliability

Shandong Tiannuo offers two main models of double-head tamping machines: TNSTDCDGJ150 and TNSTDCDGJ150. Both are identical in basic performance; the main difference lies in the TNSTDCDGJ150's 50° leg angle adjustment, making it suitable for track bed operations with a certain slope or special structure.

Key Performance Highlights:

High-Efficiency Vibration System: 40Hz high-frequency vibration combined with a large-displacement hydraulic motor enables rapid and deep ballast compaction.

Flexible Operation Capability: 360° rotation and optional leg-lifting function allow the equipment to operate flexibly in complex sections such as curves and turnouts.

Strong Compatibility: Adaptable to various mainstream construction machinery, reducing user equipment investment costs.
