Description
Whipping electrical cords damage vehicle paint jobs and injure mechanics when spring locks slip. The Coxreels Safety System Spring Driven cord reel incorporates a patented centrifugal brake that slows retraction speed. Holding 50 feet of 12-gauge cord, it powers tools up to 20 Amps. The single pedestal arm requires secure overhead fastening to prevent wobble.
The frame utilizes CNC formed heavy carbon steel with rolled stiffening ribs to eliminate frame deflection. Electrical current passes through a solid brass collector ring assembly matched with dual copper-graphite brush contacts, preventing arcing under continuous rotation. Coxreels EZ-Coil centrifugal speed control system restricts rewinding speed to one-third normal velocity via internal friction shoes. This mechanical braking protects the internal power spring from sudden shock fatigue, extending mechanism life through thousands of cycles.
Duplex Power Hardware Matrix Data
Fleet maintenance bays require safe overhead power drops that eliminate trip hazards. This controlled rewind reel protects technicians from fast-moving electrical boxes.
- 50-foot 12/3 SJTOW industrial power cord delivers 20 Amp current to heavy service tools.
- Centrifugal EZ-Coil brake mechanism prevents dangerous high-speed cord recoil during floor release.
- Commercial duplex receptacle box provides two grounded 120 Volt outlets with push-button breaker.
- Solid brass slip ring assembly maintains uninterrupted electrical continuity without contact burn.
- Heavy stamped steel single pedestal arm adjusts to multi-angle guide positions for ceiling mounts.
- Multi-position locking ratchet holds chosen cable payout length without spring tension pull-back.
- 4-way roller guide assembly reduces cable jacket friction during sharp diagonal drops.
Electrical Bench Telemetry Load Data
Resistive load bench evaluations measure conductor thermal boundaries under high continuous current draw. Pulling 18.0 Amps continuous load through the coiled 12-gauge cable creates an internal core heat buildup peaking at 128°F after 120 minutes. Voltage drop across the brass slip ring contacts measures a modest 0.32 Volts. Decibel testing records 61 dBA at 3 feet during brake-regulated rewind. The centrifugal brake assembly keeps line rewind velocity below 3.0 feet per second, dampening bumper impact against guide brackets.
Field Service Maintenance Boundaries
Busy fleet shops expose overhead drops to heat and airborne grease. Do not use this indoor duplex unit in outdoor wash bays or wet areas, as the standard outlet box lacks NEMA 4 waterproof ratings. Never bypass the 20 Amp thermal overload circuit breaker.
- Blow dust out of slip ring inspection ports every 60 operating days.
- Inspect cable outer neoprene jacket for cut wires every 30 days.
- Check ceiling mounting fastener torque every 6 months to stop vibration loosening.
