Masterpac PMR40R Tamping Rammer

The Lightweight Specialist for Narrow Trenches & Tight Access

When you need to compact in spaces where standard equipment simply won't fit, the Masterpac PMR40R is the industry solution. Weighing in at just 46kg, this ultra-compact 4-stroke rammer is engineered specifically for narrow trench work, utility installations, and difficult-to-access sites.

Unlike standard rammers with 285mm wide shoes, the PMR40R features a specialized 100mm (4-inch) wide shoe, making it the perfect choice for laying fibre optic cables, plumbing lines, and working around pillars or fencing. Despite its small footprint, it delivers a massive 12.5kN of impact force, ensuring professional compaction density in the tightest of spots.

Top Features & Benefits

• Ultra-Narrow Footprint: Equipped with a 270mm x 100mm shoe, this rammer fits into trenches that standard 60kg+ rammers cannot enter.

• Lightweight Maneuverability: At only 46kg, it is easily lifted by a single operator and ideal for sites with difficult entry points.

• Hard-Hitting Performance: Powered by the reliable Robin EH09 (2.9HP) engine, it punches above its weight class with 12.5kN of impact force and up to 700 blows per minute.

• Built to Last: Features a German-manufactured polyurethane ribbed bellow and a laminated wood-and-steel shoe designed to withstand heavy shock without delaminating.

• Operator Comfort: The heavy shock-mount system isolates the handle from the foot, significantly reducing Hand-Arm Vibration (HAV) for the operator.

• Jobsite Ready: Includes a protective top frame cover to prevent engine damage and a rust-free, durable plastic fuel tank for long-term reliability.

• Easy Transport: Comes with a convenient top front roller for easy loading into utes and vans.

Ideal Applications

• NBN & Fibre Optic Trenching: The 100mm shoe is perfectly sized for narrow cable trenches.

• Plumbing & Drainage: Compacting fill around narrow pipework.

• Fencing & Footings: Working around fence posts or in tight foundation corners.

• DIY & Landscaping: Easy for non-experts to handle due to its light weight.

Why Choose the PMR40R? Most rammers are built for "general purpose" open trenching. The PMR40R is a precision tool. If your business handles cable laying, fencing, or narrow plumbing, this unit saves you from hand-tamping tight corners and ensures your compaction meets engineering standards even in the smallest gaps.
