Versatile Outrigger Ballast Tamper for Excavators Advanced Railway Tamping Solution
For complex railway maintenance tasks, especially in congested areas like switches and crossings, specialized equipment is required. Our Outrigger (Folding-Arm) Ballast Tamper is a state-of-the-art hydraulic attachment that offers enhanced flexibility and precision. With its unique tilting mechanism, this attachment provides a distinct advantage for tamping in tight spots, making it an invaluable tool for modern rail infrastructure projects.
Advanced Design for Superior Accessibility
Unlike standard tampers, the outrigger or "folding-arm" design allows the tamping heads to be tilted and folded, providing a significant benefit when working around obstacles such as rails, signal equipment, or complex track geometry. This feature is particularly crucial for tamping turnouts (points and crossings) where space is limited and the operation requires a high degree of maneuverability. The 85° tilting angle enables the machine to reach and tamp areas that would be inaccessible to rigid tamping units.

Operational Advantages
Precision Tamping: The ability to tilt ensures that the compaction force is applied exactly where it's needed, even under challenging track configurations.
High-Frequency Vibration: Operating at 40 Hz (for the TNTZDGJ150 model), this attachment provides rapid and effective ballast compaction, improving the stability and lifespan of the track.
Robust Construction: Built with a heavy-duty frame and powerful hydraulic motors, the attachment is designed for the demanding conditions of railway maintenance, offering reliable performance and reduced maintenance downtime.
By integrating our excavator-attached outrigger tamper, your railway maintenance team can achieve higher efficiency and precision with a single machine, reducing the need for larger, more expensive specialized machinery.
