Ballast tamper
Usage: tamping ballast under railroad ties
Application: plain rail and railroad switch
Verification: CE, CRCC
Type: hydraulic, internal combustion engine, electric, flexible shaft
A ballast tamper 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.
Indispensable Ballast Tamper Machine
For existing lines
During the train operation, some ballast will sink to the subgrade because of load or environmental reasons, which leads to part of the railroad track going down and uneven surfaces affecting the safety of the rails. Ballast is added and penetrated to raise the rails to their original place, and then compacted under the ties by the indispensable ballast tamper machine.
For newly built lines
Newly built railroad tracks also need ballast tamping operations to meet the requirements of the designed elevation. In the past, manual operation with simple tools was the principal way of ballast tamping. Now, the heavy labor-intensive work is replaced by advanced machines.
AGICO is proficient in designing and manufacturing rail tamping machines and other rail maintenance equipment such as ballast cleaners, rail grinding machines, rail tensors, rail cutting machines, rail drilling machines, rail benders, rail bolt wrenches, etc.
YD-22 II hydraulic rail tamping machine has gained a CRCC certificate. The portable rail tamper series, YD, YCD-32 series rail switch tamping machine, and ND-4.2×4 flexible shaft rail tamping machine have gained CE certifications.

How does our rail tamper machine work?
The tamping machine works on the principle of the eccentric shaft connecting rod swing vibration and one-step support. The tamping tines transfer the vibration force to the ballast so that the ballast vibrates and moves in a relatively stable direction, increasing the track bed’s density. At the same time, the tamping tine squeezes the ballast between the sleepers to the bottom of the sleepers under the action of clamping, making the ballast at the bottom of the sleepers denser, thereby improving the stability of the track and ensuring the safety of driving.
