Description
Eliminate drive belt maintenance on remote job sites with the IMER Workman II 250 Multi-Mixer. This machine batches six cubic feet of wet mud inside a nine cubic foot steel drum. A dependable Honda engine drives the oil-bath gear transmission. You must grease the wheel hubs before towing high speeds on interstate routes.
The frame uses heavy structural steel tubing joined to an ASTM A36 channel iron tow cradle. A 5.5 HP Honda GX160 gas engine spins the drum at 24 RPM through a direct-drive oil-bath gearbox, eliminating belts and external gears. Unboxed machine weight totals 500 lbs, with dimensions measuring 72 inches long by 35 inches wide by 56 inches high on highway torsion suspension axles.
Key Features of IMER Workman II 250
Commercial stone masons buy IMER Workman II 250 units to pour structural mortar while tracking pro fleet pricing on durable machinery. Masonry contractors mix high-density slump batches without worrying about drive belt slippage on remote jobs.
- Gas Honda engine delivers proven 5.5 horsepower through an enclosed oil-bath gear reduction.
- Aggressive drum paddle layout lifts and folds stiff masonry mortar without wall buildup.
- Highway towing package features high-speed hubs with independent rubber torsion suspension arms.
- Worm gear dump system rotates drum tilt through a large handwheel without back-drive.
- Heavy gauge carbon steel drum withstands continuous aggregate wear without cracking.
- Retractable tow bar tongue detaches to prevent theft and save space on tight jobsites.
- Steel forklift pockets allow rapid machine movement across rough commercial construction job sites.
Torsion Suspension Gearbox Load Tolerances
Bench dynamometer runs verify extreme torque delivery under stiff slump resistance. The Honda GX160 gas engine drops just 120 RPM under a 550-pound payload of structural mortar mix. Gearbox casing temperatures hold at 140 degrees Fahrenheit during uninterrupted eight-hour mix runs. Drum runout measures under 0.038 inches total radial deflection along the outer steel bead. Torsion suspension arms flex 0.60 inches under full gross trailer weight, absorbing washboard road impacts without frame weld distortion.
Highway Towing Service Operation Limits
Towing tracks true behind half-ton trucks, while the worm drive tilt wheel enables controlled dumping straight into mortar pans without operator kickback. Glove-friendly levers lock positive. Do not buy this gas-powered unit for enclosed basement renovations or occupied building interiors lacking external ventilation. It belongs outside.
- Grease the drum pivot bearings every forty hours using marine EP grease.
- Drain and refill gearbox oil after the initial fifty-hour run period.
- Wash internal drum mixing paddles before wet cement bonds to metal faces.
