Detailed Pre-Operation Checklist for Low Bed Trailers
Introduction
Pre-operation inspections of low bed trailers are critical for safe heavy equipment transport and preventing costly accidents or equipment damage. This comprehensive checklist is designed to help operators thoroughly inspect the trailer's structural integrity, connection systems, hydraulic components, and safety features before loading and transporting valuable heavy machinery. Regular, systematic inspections not only ensure regulatory compliance but also extend equipment lifespan and prevent transport incidents.
Following this detailed pre-operation checklist for low bed trailers helps verify the readiness of ramps, locking pins, tires, hydraulic systems, and air lines while ensuring proper load distribution and securement. The checklist covers all critical components including the deck structure, suspension system, lighting, braking, and connection mechanisms specific to low bed/lowboy trailers used in heavy haulage and construction operations.

Pro Tips for Effective Low Bed Trailer Inspection
- Check Ground Conditions: Before loading, ensure the ground is level and firm enough to support the trailer weight plus the equipment. Soft or uneven ground can cause stability issues during loading/unloading.
- Inspect Approach Angle: Verify that the approach angle between the ground and loading ramps is appropriate for the equipment being loaded. Too steep an angle can cause equipment to bottom out or become unstable.
- Verify All Pins and Locks: Double-check that all removable gooseneck pins, locks, and latches are fully engaged and secured before moving. A partially engaged lock can fail during transit.
- Document Weight Distribution: Calculate and document the distribution of weight across trailer axles to ensure compliance with axle weight restrictions for your planned route.

Detailed Inspection Procedures
Follow these structured procedures to ensure a thorough pre-operation inspection of your low bed trailer. Adapt these steps to your specific trailer type and operating conditions.
Removable Gooseneck (RGN) Inspection
- Ensure trailer is on level, stable ground
- Visually inspect gooseneck for damage, cracks, or bent components
- Check hydraulic cylinders for leaks or damage
- Verify all pins are properly seated and locked
- Test hydraulic operation of detachment mechanism (if safe to do so)
- Inspect front trailer support legs for stability and function
- Check connection points between gooseneck and trailer bed
- Verify all safety locks are engaged when gooseneck is attached
Hydraulic Systems Check
- Inspect hydraulic fluid level in reservoir(s)
- Check fluid for discoloration or contamination
- Inspect all visible hydraulic hoses for leaks, wear, or damage
- Verify all fittings are tight and not leaking
- Test hydraulic functions at low pressure first
- Check for smooth operation of all hydraulic components
- Listen for unusual noises during operation
- Verify all hydraulic controls function properly
Loading Ramp Inspection
- Visually inspect ramps for structural damage or deformation
- Check ramp hinges and pivot points for wear or damage
- Verify ramp surface has adequate traction
- Test ramp deployment mechanism for smooth operation
- Check hydraulic cylinders for leaks (if hydraulic ramps)
- Verify ramp locks engage and hold securely
- Test ramp angle and stability for intended load
- Ensure ramp width is appropriate for equipment to be loaded
Air Brake System Check
- Connect air lines to tractor and build system pressure
- Check for audible air leaks throughout system
- Verify glad hand connections are secure with no leaks
- Test automatic brake application when air supply is cut
- Inspect brake chambers for damage or cracks
- Check slack adjusters for proper adjustment
- Verify ABS system shows no warning lights
- Test brakes with driver to ensure proper function
