Description
Off-road service trucks shake light single-arm hose reels until mounting welds crack and fail. The Coxreels Hose Reel Supreme Duty unit features dual-pedestal steel supports holding 75 feet of 1/2-inch air and water line. Rated at 300 PSI, it feeds large pneumatic impact tools. Its heavy 60-pound frame requires reinforced steel truck decking.
The dual-pedestal chassis uses dual 1/4-inch steel support arms welded to a heavy 10-gauge formed base to prevent axle deflection under severe side pulls. Air and water flow through an external solid brass 90-degree full-flow swivel packed with nitrile seals, preventing restriction under constant oscillation. A 1-inch solid cold-rolled steel axle turns inside dual self-aligning pillow block bearings. The enclosed multi-leaf power spring cartridge produces sustained retraction torque, resisting fatigue caused by washboard haul roads.
Supreme Duty Pneumatic Matrix Data
Quarry service trucks require extreme chassis rigidity to prevent drum bind under heavy pull angles. Dual-pedestal architecture stabilizes extended medium-diameter pneumatic hose lines.
- 300 PSI working pressure rating handles high CFM industrial shop air and mobile equipment wash water.
- 75-foot 1/2-inch inside diameter hose capacity reaches machinery across wide equipment staging pads.
- Dual pedestal steel frame geometry eliminates axle deflection during hard off-axis line retrieval.
- Machined brass full-flow external swivel maintains unrestricted airflow to pneumatic impact wrenches.
- Self-aligning pillow block bearings deliver frictionless spool rotation under heavy hose tension.
- Multi-position locking pawl mechanism secures working hose extension without ratchet slipping.
- Heavy rolled-edge steel drum discs protect outer hose rubber jackets from sharp edge cutting.
Pneumatic Rig Dyno Telemetry Data
High-volume pneumatic bench tests evaluate flow restrictions through the brass core. Passing 45 CFM at 125 PSI through the 90-degree swivel induces a modest 4.4 PSI pressure drop across the 75-foot core. Continuous airflow creates a minor 8°F temperature decrease at the brass swivel due to air expansion cooling. Acoustic sound output measures 70 dBA at 3 feet during full spring retraction. The dual-pedestal spring motor yields 30 inch-pounds of retraction torque, pulling 75 feet of rubber air hose across wet gravel without line stall.
Field Service Maintenance Boundaries
Severe off-road service environments test mechanical integrity. Do not connect this reel to high-pressure pressure washers or hydraulic pumps exceeding 300 PSI, as the brass swivel body will rupture under hydraulic shock. Do not mount on thin unreinforced sheet metal panels.
- Inspect swivel brass threads and nitrile O-rings every 90 days.
- Lubricate guide arm rollers every 60 days to prevent flat spots.
- Verify mounting bolt tightness every 200 miles on rough off-road terrain.
Commercial Warranty Package Contents
Factory coverage includes a 2-Year limited commercial warranty covering structural frame failure, drive spring fatigue, and swivel assembly defects. The carton contains the assembled dual-pedestal hose reel, external brass 90-degree air swivel, 4-way roller guide bracket assembly, adjustable rubber line stop, and installation hardware manual without hose.
