Allen Engineering 40V 1.5HP E-Screed Magic Screed with Battery Backpack Power Unit

Description

Tired of breathing noxious gas fumes inside enclosed commercial buildings during concrete pours? The Allen 40V 1.5HP E-Screed delivers clean electric screeding power via an ergonomic battery backpack. Its brushless motor matches small gas engine torque without cord restrictions, though cold weather will shorten continuous battery runtimes between pack charges.

Cast aluminum alloy encloses the high-torque brushless electric motor, keeping the power head weight to just 12 lbs bare. The backpack harness system holds a 40V lithium-ion battery pack, drawing 28 amps at peak draw. Footprint measures 16 inches by 14 inches by 22 inches on the carrier frame. High-efficiency motor windings spin at 7,500 RPM, delivering mechanical vibration straight to clamped screed blades without tailpipe exhaust emissions.

Key Features of Allen MESCRD

Specialty floor contractors who buy Allen MESCRD systems benefit from competitive commercial battery screed pricing while meeting strict indoor emissions standards on occupied buildings.

• Brushless 1.5HP equivalent 40V electric motor supplies high torque without pull-starter cords or gas mix maintenance
• Zero emissions architecture allows continuous indoor operation inside hospitals, basements, and food processing plants
• Ergonomic backpack harness distributes battery pack weight evenly across operator shoulders to ease lower back stress
• Universal clamping mechanism mates with standard Magic Screed blade profiles ranging from four to sixteen feet
• Variable speed throttle trigger enables real-time vibration adjustments based on varying concrete slump levels
• Rugged aluminum motor housing repels caustic concrete splatter while keeping internal electronics well protected
• Integrated power display shows battery percentage to prevent unexpected power drops midway across pours

Brushless Motor Output Tolerances

Bench dynamometer tests reveal a sustained 1.5 HP mechanical output with zero torque sag under heavy slurry loads. The motor holds 7,200 loaded RPM against a 12-foot blade in 3-inch slump concrete, drawing 24 continuous amps. Thermal imaging confirms motor housing temperatures stay below 145 degrees Fahrenheit during 45-minute continuous run cycles. Vibratory energy transmission remains crisp, matching the compaction force of four-stroke 35cc gas engines without harmonic bogging, spark plug fouling, or fuel throttle lag.

Field Usability Realities

The padded backpack harness balances nicely, isolating the battery pack from sudden operator movements. Variable throttle control feels smooth through thick rubber work gloves. Do not buy this electric screed system for remote highway pours where on-site generator power or spare battery docks do not exist.

• Blow dry dust and cement particles from battery connector terminals using clean compressed air
• Wipe the aluminum motor casing with a damp towel rather than spraying direct high-pressure hose water
• Store 40V lithium batteries at room temperature to preserve maximum cell charging capacity

Allen Warranty Equipment Manifest

Allen Engineering backs this E-Screed power unit with a 1-Year limited manufacturer warranty against motor and electrical defect issues. The factory carton includes the 40V E-Screed power unit, one padded battery backpack harness, quick-connect cable setup, mounting clamp hardware, and an illustrated operator instruction manual.
