MasterPac PMR Series Tamping Rammers:
Hard-Hitting Compaction with Unrivalled Operator Comfort

The MasterPac PMR Series of Tamping Rammers (often called "Jumping Jacks") delivers powerful, consistent, and reliable compaction for a wide range of construction and civil works applications.
Engineered for the most demanding environments, these four-stroke vibratory rammers are the industry standard for compacting cohesive and granular soils in confined areas.
Featuring robust, reliable engines (such as Honda GX/GXR or Yanmar Diesel options) and an advanced anti-vibration system, the MasterPac PMR Series maximizes productivity while prioritizing operator safety and comfort.

Key Features & Benefits:

1. Hard-Hitting Compaction: Perfectly balanced design delivers optimal impact force (up to 18 kN on the PMR85D) and jumping stroke (40−85 mm depending on model) for superior soil and asphalt density in fewer passes.
2. Operator-Centric Design:
• Heavy Shock Mount System: Significantly reduces hand-arm vibration (HAV), improving operator comfort and safety for longer work periods.
• Low Noise and Low Emission Engines: Equipped with reliable 4-stroke engines (like the Honda GX100, GXR120, or Yanmar L48 Diesel) for cleaner, quieter operation compared to older 2-stroke models.
3. Maximum Durability:
• German-Manufactured Polyurethane Ribbed Bellow: Provides superior long-term performance and is often backed by an extended warranty.
• Laminated Wood and Steel Shoe: Designed to absorb and withstand extreme vibration shock for extended life.
• Protective Engine Cover: A robust top frame eliminates potential damage to the engine during operation or transport.
• Durable, Rust-Free Fuel Tank: Constructed from hard-wearing plastic for longevity.
4. Ease of Use & Transportation:
• Convenient Top Front Roller: Simplifies loading and unloading onto transport vehicles.
• Bottom Lifting Handle: Provides an easy, balanced point for manual lifting.
• Optional Trolley Wheel Kit: Available for effortless on-site transportation.

Models to Suit Every Job: The series includes models ranging from lightweight and nimble (e.g., PMR60H at 60 kg) to heavy-duty diesel options (e.g., PMR85D at 85 kg), ensuring the right tool for any job site requirement.
