Trailers Buyer Guide

• Typical price ranges for used heavy equipment trailers can be from $8,000 for utility models to over $150,000 for specialized multi-axle lowboys.
• Operating weight capacity ranges from 5,000 lbs for small utility trailers to over 100,000 lbs for large industrial transport trailers.
• Trailers generally don't have 'hours-of-life' but rather 'miles-of-life' or 'years-of-service', with well-maintained units lasting 20+ years.
• Fuel usage is indirect, impacting the towing vehicle's consumption significantly based on trailer weight and aerodynamics.
• Common attachments/features include ramps (manual, hydraulic, air ride), winches, beaver tails, custom tie-downs, and expandables.
• Jobsite uses range from moving excavators, bulldozers, and loaders to transporting aggregates, building materials, and portable jobsite offices.

• 1**Frame Integrity:** Closely inspect the main frame rails and crossmembers for any signs of bending, cracking, or previous weld repairs that appear unprofessional or compromised.
• 2**Axles and Suspension:** Check for bent axles, worn leaf springs, cracked air bags, and proper alignment. Uneven tire wear can indicate alignment issues.
• 3**Tires and Wheels:** Assess tire tread depth, sidewall condition for cracks or bubbles, and ensure no dry rot. Check wheels for damage, cracks, or signs of overheating.
• 4**Braking System:** Verify air lines or hydraulic lines are intact, free of leaks, and not chafed. Inspect brake drums/rotors and pads/shoes for wear, and test brake functionality.
• 5**Decking/Flooring:** Look for rotting wood, heavily corroded metal, or significant damage that could compromise load support or safety.
• 6**Ramps and Tailgate:** Ensure ramps deploy and retract smoothly (if powered) and are structurally sound. Check hinges, pins, and locking mechanisms on tailgates.
• 7**Lighting and Electrical:** Confirm all lights (marker, brake, turn) are working, wiring is intact and protected, and connectors are clean and functional.
• 8**Kingpin/Hitch Assembly:** For semi-trailers, inspect the kingpin for wear and damage. For bumper pull or gooseneck, check the hitch coupler and safety chains.
• 9**Rust and Corrosion:** While some surface rust is normal, excessive rust on structural components, particularly near welds or stress points, is a red flag.
• 10**Hydraulic Components (if applicable):** For hydraulic ramps or detachable goosenecks, check for leaks around cylinders, hoses, and connections. Test pump operation.
