Multiquip Power Trowel B46H11H 46 Inch Concrete Finishing Machine (10.7 HP Honda GX340 Engine QXH QuickPitch Handle 4 Blades 90-155 RPM Rotor Speed)

Industrial Walk Behind Concrete Finishing System with Rapid Angle Engagement Controls

The Multiquip B46H11H 46-Inch Walk-Behind Power Trowel is a high-production concrete finishing machine engineered to achieve flat, wave-free surfaces on commercial, industrial, and large-scale residential slabs. Driven by a 10.7 HP Honda GX340 gasoline engine operating at 3600 RPM, this industrial power unit spins a 4-blade rotor assembly at velocities ranging from 90 to 155 RPM to handle both panning and final burnishing phases. The technical configuration integrates a proprietary QXH QuickPitch handle system that allows operators to execute precise, instantaneous blade pitch adjustments on the fly, optimizing finishing metrics as the concrete sets. For jobsite safety compliance, the unit features a responsive centrifugal clutch combined with an automated dead-man safety switch that instantly halts rotor movement if the operator releases control of the handle assembly.

Best Used For:

• Commercial Warehouse Floors: Finishing expansive internal floor slabs to strict flatness and levelness specifications.
• Parking Structure Slabs: Burnishing structural concrete multi-level decks and elevated parking garage foundations.
• Industrial Flatwork Production: Managing rapid-setting exterior or interior concrete pours requiring massive high-torque finishing output.

Key Performance & Safety Features

• Honda GX340 Gas Engine: Delivers 10.7 HP of high-torque mechanical force at 3600 RPM with first-pull recoil start reliability.
• QXH QuickPitch Handle: Proprietary spring-loaded engagement system provides instantaneous, micro-adjustable blade angle mechanics.
• Centrifugal Safety Switch: Integrated dead-man safety override halts the rotor drivetrain immediately if control handles escape the operator.
• Heavy Duty Gearbox and Spider: High-density internal gear tooth layouts and robust spider arms resist severe deflection under high-load panning strain.
• Rugged Guard Ring Framework: Thick structural steel outer ring shields the rotating blade tips and allows operation adjacent to walls or columns.

What's Included

Technical Specifications

Pro-Tip: When shifting from float pans to finishing blades, wipe the grease fittings on the spider assembly clean before lubricating. Removing concrete slurry grit prevents fine abrasive track buildup inside the blade arms, ensuring your QXH handle retains low friction micro-adjustments at maximum RPM loops.
