The Wenbro 4-Stroke Petrol Compaction Rammer is a 4hp petrol-powered rammer weighing 80 kg, built for trench compaction, pothole repair, and foundation preparation. The 4-stroke engine eliminates fuel-oil mixing on site, delivers 18 kN centrifugal force, and runs on a 2.8-litre fuel tank — balancing power, convenience, and running cost for everyday compaction work. Tried and tested in Wenbro’s hire fleet, with in-house spares and service support.
Applications
- Compacting backfill in trenches for pipeline, cable, and utility installation
- Pothole repair and road patching on municipal and civil road maintenance contracts
- Foundation preparation and sub-base compaction on building sites
- Compacting soil and granular fill in confined spaces and narrow excavations
- General trench compaction on construction and civil projects requiring a no-mix-fuel engine
Features:
- HIGH PERCUSSION RATE: 700 blows-per-minute (around 12 per second), ensuring deep, uniform compaction with fewer passes.
- RUGGED 80KG STRUCTURE: Perfectly weighted to drive downward impact force into the ground while remaining manageable for operators.
- COMPACT ENGINEERING: Built to manoeuvre effortlessly around tight corners, pipe trenches and close-quarters foundations.
- HEAVY DUTY RAMMING FOOT: A 330mm x 285mm foot plate designed to last while maximising impact pressure.
- 2-STAGE AIR-FILTER: Superior dust suppression minimises downtime due to dust-clogging.
Pro Tip:
Let the machine do the work. Guide the Rammer with a firm but relaxed grip rather than forcing it down. Forcing or leaning heavily on the handle does not improve compaction; it actually disrupts the machine’s natural vertical jump, reducing your impact force and increasing operator fatigue.
