Description
Internal multi-stage compression springs convert rotational torque into vertical percussion force inside the Bartell Morrison BT1400 Compacting Rammer. This jumping jack delivers 3100 lbs of impact force on cohesive trench soils. A commercial Honda engine powers the heavy crank gear. You must secure the transport dolly wheel bracket before rolling across rough ground.
Bartell Morrison casts the gear housing from ductile iron and connects it to an eleven-inch laminated wooden and steel shoe. A 3.5 HP Honda GX120 four-stroke engine spins the internal crank mechanism, delivering up to 695 blows per minute. The unboxed tool weighs 163 lbs. Machine dimensions measure 30 inches long by 15 inches wide by 41 inches high with height-adjustable operator guide handles.

Percussion Output Crank Case Tolerances
Soil test pit evaluations verify consistent impact force through the crank and spring drive train. The Honda GX120 engine operates at 3600 RPM under load, dropping less than 130 RPM when striking stiff clay backfill. Percussion output holds at 695 blows per minute with stroke travel reaching 2.6 inches. Piston guide runout measures under 0.007 inches TIR within the sealed oil bath. Gearcase operating temperatures level off at 136 degrees Fahrenheit after four continuous hours of soil compaction testing.
Trench Handling Transport Dolly Limits
Guiding this 163-pound rammer along ditch floors is manageable thanks to the adjustable handle height, allowing operators of different statures to maintain leverage. The included two-wheel dolly makes solo yard transport practical. Do not buy this machine for indoor basement trenches lacking ventilation, or for smoothing surface asphalt.
- Inspect engine oil levels with the dipstick before every work shift.
- Check the sight glass oil level on the lower ramming leg once per month.
- Tighten shoe mounting bolts with a torque wrench every twenty operating hours.
