The CV3 Electric-Powered Flex-Shaft Drive Vibrator Motor is engineered for serious concrete consolidation applications, blending unmatched performance, jobsite durability, and operator-focused features. Built by Multiquip—renowned for rugged, high-productivity tools in the concrete industry—the CV3 is the go-to solution for contractors tackling large pours, deep forms, or demanding mix conditions where vibration strength and reliability are key.

Product Overview: CV3 Electric-Powered Flex-Shaft Drive Vibrator Motor

This high-output, 3 HP electric motor is designed specifically for use with heavy-duty steel and rubber vibrator heads (up to 2-5/8" in diameter) and flex shafts ranging from 3 to 21 feet in length. The CV3 excels in medium to high-slump concrete, making it ideal for everything from foundation pads and retaining walls to bridge decks, columns, structural slabs, or high-rise pours.

Key Features & Benefits

• Robust 3 HP Motor: Delivers substantial torque and reliable vibration, even under continuous use or in stiff, aggregate-heavy mixes. Available in both 115V (CV3A) and 230V (CV3B) to match jobsite power supplies.

• High RPM Output: Up to 19,250 RPM ensures rapid concrete consolidation, minimizing the risk of voids, honeycombing, or surface blemishes in large or deep pours.

• Cassette-Style Motor: Minimizes internal friction, maintains optimal RPMs under load, and makes replacement and maintenance simpler—extending product life and daily reliability.

• Quick-Disconnect Knob: Allows tool-free attachment/removal of shafts, reducing job setup time and enabling fast head or shaft changes when moving between forms or depths.

• Isolated Vibrating Handles: Large rubberized handles minimize vibration exposure to the operator and protect the motor from shock or accidental drops.

• Strain Relief and Ventilation: Built-in cord protector prevents pull-out failures while rear-mounted ventilation keeps dust out and the motor running cool, even on the messiest pours.

• UL and CSA Compliance: Fully tested for U.S. and Canadian safety standards for maximum jobsite confidence.

• Steel Outer Casing: Stands up to tough conditions, impacts, and daily transport abuse, ensuring long-term value.

Technical Specifications

Performance & Versatility

The CV3 is a contractor’s favorite for high-production slabs, industrial pads, bridge decks, tall columns, caissons, and wherever rapid, thorough consolidation is vital. It drives heads up to 2-5/8" with ease—ensuring deep vibration for thick lifts or wide forms. Compatible with a spectrum of steel heads and heavy-duty flex shafts, it enables crews to tailor their gear for the job, whether it’s a 10-foot deep wall or a 100-foot slab.

Flow-through ventilation cools the housing and minimizes concrete dust buildup, further boosting reliability and reducing service intervals. The system is designed for continuous runtime, suitable for multi-hour pours with minimal operator fatigue.

Durability, Maintenance & Safety

• Steel Casing & Heavy-Duty Internals: Made to handle drops, vibration, and rough transport without loss of function.

• Accessible Service Points: Cassette motor and removable brushes make repairs/maintenance quick and straightforward.

• Isolated Handles & Strain Relief: Ergonomic operator comfort helps prevent repetitive stress injuries, while robust strain reliefs prevent wire fatigue.

• UL/CSA Certification: Fully meets electrical and safety codes for North American construction use.

Application Examples

• Large slabs, floors, and bridge decks

• Columns, tall or custom forms, deep footings

• Retaining walls, foundation mats, commercial buildings

• High-rise repetitive pours, infrastructure repairs

Industry-Leading Compatibility

• Shafts: Works with FS series flexible shafts (3–21 ft), letting crews easily adapt to pour depth and form height on any job.

• Heads: Compatible with steel/rubber heads from 1-3/8" to 2-5/8" in diameter—providing flexibility for mix/slump and form detail.

• Power Supply: 115V or 230V models accommodate North American and international jobsites.
