Description
Mix massive mortar batches inside occupied buildings without tripping carbon monoxide detectors or choking workers on exhaust. The IMER Mortarman 120 Electric Mixer runs a 5-HP electric motor to spin twelve cubic feet of stiff mortar. Masons keep block crews supplied. Starting under cold ambient conditions demands dedicated thirty-amp 230-volt single-phase power drops.
Heavy spun steel forms the twelve-cubic-foot drum to resist aggregate scour. A totally enclosed fan-cooled 5-horsepower electric motor operates on 230V single-phase current drawing 24 full-load amps. An enclosed direct-drive oil-bath gearbox eliminates external belts and chains to direct maximum torque to the paddle shaft. The towable trailer frame rides on pneumatic highway tires with leaf-spring suspension. Net machine weight sits at 680 lbs with dimensions of 48 inches wide by 62 inches long by 56 inches high.
Key Features of IMER 1130122
Commercial masonry contractors buy IMER 1130122 mixers when commercial mortar mixer pricing requires clean indoor performance without gas emissions. This unit mixes structural block mortar, brick mud, stone grout, stucco, and repair mortars.
- Twelve-cubic-foot steel drum mixes up to four full bags of dry mortar per batch.
- Totally enclosed 5-horsepower electric motor delivers continuous high torque without gas fumes.
- Direct-drive oil-bath gearbox eliminates belt slip, open pulleys, and drive chain adjustments.
- Bottom discharge chute drops mixed mortar straight into wheelbarrows or pump hoppers.
- Planetary paddle blades sweep drum walls clean to prevent dry cement crust buildup.
- Leaf spring trailer suspension protects internal drive gears during highway towing behind trucks.
- Safety cutoff switch stops paddle rotation the instant the operator opens the grill.
Direct Drive Gearbox Bench Diagnostics
Tachometers measure central paddle rotation at 38 RPM under a 1100-pound wet mortar load. Motor current draws 22.8 amps during continuous mixing, peaking at 28.5 amps when charging dry cement bags into sand. Motor casing temperatures stabilize at 146 degrees Fahrenheit after ninety minutes of continuous batching. The sealed oil-bath gearbox exhibits zero oil weeping or foaming under heavy shop resistance tests. Operating sound levels remain below seventy-four decibels during full-power indoor mixing runs on shop concrete floors. Shaft seals prevent mortar slurry migration into internal gear bearings.
Indoor Usability Paddle Upkeep Procedures
The compact frame fits through commercial double doors for basement and high-rise slab prep. Bottom slide gate discharge eliminates heavy drum tipping and reduces splashout onto finished subfloors. Do not buy this machine for structural concrete mixes containing coarse two-inch river rock aggregate.
- Flush the drum interior and bottom slide gate with water after finishing work.
- Check electrical plug terminals for corrosion prior to connecting to 230V power.
- Inspect gearbox oil levels through the sight plug every six months.
