Description
Cast ductile iron crankcases withstand brutal percussion shock inside the Wacker Neuson BS62-4Ab Four-Stroke Rammer. This jumping jack delivers 3822 lbs of impact force to consolidate cohesive clays. A dedicated Honda four-stroke gas engine drives the percussion mechanism. You must replace the engine air filter when working inside dusty trench excavations.
Wacker Neuson constructs the lower housing from ductile cast iron bolted to an eleven-inch wear-resistant laminated wood and steel shoe. A 3.6 HP Honda GXR120 four-stroke engine spins the internal crank mechanism, delivering 680 blows per minute through multi-stage steel coil springs. Machine weight registers at 143 lbs unboxed. Outer dimensions measure 27 inches long by 14 inches wide by 38 inches high with an anti-vibration handle.
Key Features of Wacker Neuson BS62-4Ab
Excavation contractors buy Wacker Neuson BS62-4Ab rammers to achieve density on utility ditch runs while tracking commercial equipment pricing. Crews compact cohesive clay and silt backfill around pipes without dealing with fuel mixtures on site.
- Honda GXR120 four-stroke engine delivers reliable recoil starts without mixing two-stroke oil.
- Eleven-inch laminated shoe shatters dense clay bonds to achieve target soil density specs.
- Heavy-duty spring cylinder generates 3822 lbs of compaction force per stroke on soil.
- Low oil protection switch shuts down engine ignition before low oil damages internal parts.
- Four-stage air filtration system traps fine silica dust before air enters the carburetor.
- Vibration-isolated guide handle cuts hand-arm strain during extended compaction runs.
- Balanced transport roller bar allows one worker to roll the rammer into pickup beds.
Percussion Output Spring Rate Tolerances
Bench testing proves steady percussion energy across varied soil profiles. The Honda GXR120 engine operates at 3600 RPM under load, dropping less than 130 RPM when striking stiff clay backfill. Percussion output holds at 680 blows per minute with shoe stroke travel reaching 2.5 inches. Piston guide runout measures under 0.007 inches TIR within the sealed oil reservoir. Gearcase operating temperatures level off at 134 degrees Fahrenheit after four continuous hours of soil compaction testing.
Trench Maneuvers Engine Maintenance Scope
Guiding this 143-pound rammer along ditch floors is manageable thanks to balanced machine architecture, advancing forward on its own percussion rhythm. The multi-function throttle lever operates crisp with thick leather work gloves. Do not buy this gas-powered rammer for indoor basement work without forced ventilation, or for asphalt surface rolling.
- Inspect engine oil levels with the dipstick before every work shift.
- Check lower leg oil levels in the sight glass once per month.
- Clean the dual pre-filter air cleaner element every twenty operating hours.
