Portable Impact Rail Tamper Machine

Powered by the internal combustion engine, the portable impact rail tamper offers a solution for easy carrying without any long wires or heavy flexible shafts. It is widely used in the tamping operation of railway ballast to maintain the track bed. The novel design, compact structure, lightweight, and easy on and off track all make it ideal for plain lines and railroad switch tamping operations. We provides various models of portable rail tamper machines such as ND-5, ND-6.

Features of ND-6 Impact Rail Tamper Machine

Small in size, lightweight, and only needs one person to get the tamping work done on plain lines and railroad switches.

This is ballast tamper model SND23

A ballast tamper model SND23 is a specialized rail maintenance equipment for completing ballast tamping under railroad ties, which can dig into the track bed with vibration tines (powered by hydraulic, electric, or battery). The tamping operation is aimed at re-ordering the ballast to overcome the friction between ballasts and force it to "flow" to a more stable location so that the ballast density is increased, and the compact structure stabilizes the track bed. Rail tamping is key in ordinary maintenance, medium repair, and overhaul.

This is ND-4.2×4 flexible shaft rail tamping machine, It is suitable for any track line maintenance and ballast tamping operation. It is characterized by light weight and easy operation. Tamping has the advantages of good quality, low failure rate, convenient maintenance, quick on or off track speed and strong applicability. It can do tamping operation not only for standard lines, but also for turnouts. The machine is cost effective and very suitable for the needs of railway ballast tamping operation.
