Model 900 Utility Tamper
The small, powerful Model 900 Utility Tamper is ideal for crossings, industrial tracks and any other tamping project that doesn't require a high production tamper.
Although it is compact, it has more than enough power to give high quality results and it's rugged enough to operate week after week with little maintenance.
With four hydraulic motors supplying more concentrated power than many larger machines, the 900 uses vibratory tilt-squeeze action to tamp ballast directly under the rail where the load is carries.
One of the 900's greatest assets is simplicity. Almost anyone can be easily trained to operate it. The layout and accessibility of its components make it simple to maintain and repair. Repairs can usually be made right at the job site.
When it's time to move the 900 from one project to another, it is light enough (5 tones /4.5tonnes) and narrow enough 8' / 2.4m) to transport on highways without special permits.
This tough, versatile tamper is not only economical to buy but economical to operate.
