Reliable Equipment REL-TMP-72-FF Hydraulic Pole Tamper (Valve on Tube)

Here are the most common reasons:

-Too much downward pressure – These tampers are designed to bounce. If too much weight is applied, the internal piston cannot complete its stroke and the tool will stall.

-Hydraulic flow issue – Low oil flow, blocked couplers, or kinked hoses can cause the tamper to run but stop under load.

-Worn internal seals – If internal seals are worn, the tamper may run in the air but stop when it contacts the ground.

-Binding or debris – Dirt buildup, a bent rod, or binding in the tamper shoe can prevent proper movement when pressure is applied.

Tip: The tamper should be guided with light pressure and allowed to bounce on its own rather than forced into the ground.

Hydraulic Requirements

The REL-TMP-60-FF is designed to operate within the following hydraulic specifications:

-Flow Range: 4–6 GPM
-Operating Pressure: 1,000–2,000 PSI
-Blows Per Minute: Approximately 1,160 BPM at 5 GPM
-Configuration: Direct-coupled hydraulic tamper with hose and couplers

Most Bobcat skid steers equipped with auxiliary hydraulics can supply hydraulic flow and pressure well above these requirements. However, excessive flow may require adjustment through the machine’s hydraulic controls to avoid overdriving the tool.

Compatibility Considerations

Before connecting the REL-TMP-60-FF to a Bobcat skid steer, verify:

-Auxiliary hydraulic flow can be controlled to 4–6 GPM.
-System pressure falls within the 1,000–2,000 PSI operating range.
-Couplers are compatible or adapters are installed if the Bobcat uses a different quick-connect style.
-The hydraulic circuit type (open-center or closed-center) is configured correctly for the tamper. The REL-TMP series is designed to work with both open- and closed-center hydraulic systems.

Best Practice

When using a hydraulic pole tamper on a skid steer, allow the tamper to do the work. Applying excessive downward force from the loader arms can reduce performance and may cause the tamper to stall. Reliable Equipment specifically notes that these tampers are designed to bounce and compact under their own hydraulic action.

Conclusion

A Bobcat skid steer with auxiliary hydraulics is generally an excellent power source for the Reliable Equipment REL-TMP-60-FF Hydraulic Pole Tamper, as long as hydraulic flow, pressure, and coupler compatibility are verified before operation. For optimal performance, ensure the machine is adjusted to the tamper’s specified 4–6 GPM flow range and 1,000–2,000 PSI pressure range.
