Functional Testing Procedures
The following test procedures should be performed during the inspection to verify operational functionality of key systems:
Hydraulic Reel Handling Test
- Connect hydraulic power source (if external) or activate onboard system
- Test lifting/lowering system through full range of motion
- Verify smooth operation with no jerking, binding, or unusual noises
- Test all hydraulic adjustments (width, height, tilt) as applicable
- Check for hydraulic leaks during operation under pressure
- Verify all lock points and safety stops function properly
Brake System Test
- Connect trailer to appropriate tow vehicle
- Verify brake controller connection and settings
- Test service brakes at low speed in controlled area
- Check for equal braking on all wheels
- Test breakaway system function (if equipped)
- Verify ABS system function (if equipped)
Reel Brake & Tension System Test
- Install test reel or use proper simulation method
- Apply reel brake gradually and verify holding capability
- Test tension control system through adjustment range
- Verify brake/tension consistency during rotation
- Check emergency override function
- Test brake/tension at typical operational settings
Loading/Unloading System Test
- Test loading mechanism (hydraulic, mechanical, or manual)
- Verify all adjustment points for different size reels
- Check proper alignment of spindles and supports
- Test securing mechanisms for loaded reels
- Verify load capacity indicators or limits
- Test any specialized features (cable guides, motorized systems)
