The TMG-RM90 Jumping Jack Tamping Rammer Compactor delivers professional-grade compaction for cohesive and granular soils. Producing up to 3370 lb of impact force, it creates a firm, stable base for trench backfill, foundations and confined construction areas.

A heavy-duty internal spring system transfers powerful tamping energy through a 3.1" jumping stroke at 640-680 BPM. The compact ramming shoe concentrates force into tight spaces where wider compactors cannot work effectively.

The 3.6 HP gasoline engine provides ample power for demanding compaction work, while the 0.9 gal fuel tank supports productive operation between refuelling stops. With a 163 lb operating weight, the RM90 balances stable downward force with practical jobsite handling.

TMG also carries this model: TMG-RM80
