Description
Whipping electrical cords destroy overhead lights and injure technicians when springs snap back unchecked. The Coxreels Safety System Spring Driven cord reel solves this hazard by integrating centrifugal speed control over 100 feet of heavy cable. It features an industrial duplex outlet box rated at 20 Amps. The large 24-inch drum demands stout ceiling rafters.
The chassis relies on heavy robot-welded 12-gauge steel side arms bolted to a multi-position mounting bracket base. Copper alloy slip rings rotate against beryllium copper brushes, providing arc-free current transfer under full drum rotation. Coxreels EZ-Coil proprietary braking system uses centrifugal weights running inside a friction hub to restrict rewinding speed to one-third standard rate. This mechanical control reduces shock load on the internal power spring, increasing spring fatigue life beyond typical high-cycle shop failures.
Duplex Electrical Hardware Performance Matrix
High-traffic maintenance bays need dependable electrical drops without safety hazards. Controlled spring power eliminates loose floor cords across busy commercial fleet work areas.
- 100-foot 12/3 SJTOW cord supplies 20 Amp service for grinders, welders, and diagnostic carts.
- Centrifugal EZ-Coil brake mechanism prevents dangerous fast cord snap-back during floor retraction.
- Commercial duplex outlet box provides two 120 Volt grounded receptacles inside impact-resistant housing.
- Integrated 20 Amp circuit breaker stops conductor thermal overload during continuous shop tool usage.
- Heavy steel dual pedestal frame resists distortion when cords pull sideways across bay doors.
- Multi-directional roller guide reduces cable jacket friction during sharp overhead drops.
- Heavy-duty clock spring motor retains consistent rewind power through thousands of shop cycles.
Electrical Bench Telemetry Load Data
Continuous resistance dyno tests confirm thermal boundaries on bundled conductors. Subjecting the fully wound 100-foot 12-gauge cord to an 18 Amp constant resistive load produces a core coil temperature rise of 46°F above ambient room temperature. Slip ring contact voltage drop remains tight at 0.35 Volts. Acoustic monitoring registers 61 dBA at 3 feet during regulated spring return. The centrifugal brake restrains retraction line speed to 3.1 feet per second, preventing end-box whip impact against ceiling frames.
Field Service Maintenance Boundaries
Ceiling installations encounter shop heat and particulate grime. Do not use this indoor duplex unit in outdoor wash bays or wet fertilizer mix zones, as moisture penetration will trip main distribution panels. Never pull beyond the 100-foot yellow stop warning marker.
- Inspect cable jacket for gouges, cuts, or oil swelling every 30 days.
- Clear accumulated dust from the brake hub air vents every 90 days.
- Verify tightness of ceiling mounting bracket fasteners every 6 months of operation.
