Honest Comparison

How It Compares With the Alternatives

2-axle lowboy trailerThe 3-axle unit supports higher payloads and better weight distribution on uneven terrain, but costs more in shipping and maintenance
Non-waxed trailerWax coating prevents seawater corrosion during ocean transport, but adds a small cost and requires no extra maintenance
Single trailer packingStacking three trailers reduces freight cost per unit but requires more yard space and handling time at destination
Use Guide

Using It Well

  • Inspect the wax coating and paint finish after unloading to detect any transport damage
  • Use the hydraulic ladder only with the trailer fully supported on the landing gear
  • Keep the air suspension system checked for leaks if used in high-temperature environments
  • Store the trailer with the landing gear down and the deck clear when not in use
