Lowbed Transport: How to Specify the Right Trailer

A lowbed is built to move heavy, tall equipment—cranes, excavators, dozers, graders—safely and within height limits thanks to its low deck.

When to choose a lowbed

• Heavy/oversized machinery requiring low center of gravity.
• Bridge and signage clearance thanks to lower deck height.
• Better axle weight distribution via multiple axles.

Key specifications

1) Capacity & axles

Start with the operating weight of the machine (fuel + attachments) and add a 15–25% margin. Choose axle count accordingly to comply with per-axle limits.

2) Deck dimensions & height

Verify length/width against your largest equipment. Lower deck height improves clearance under bridges; detachable gooseneck may simplify front loading.

3) Loading ramps & approach angle

Select appropriate hydraulic ramps and consider a winch for disabled equipment. Ensure ground clearance to avoid tail dragging.

4) Permits & route survey

Oversize/overweight loads may need permits, escorts, and surveyed routes with measured bridge heights and turn constraints.

5) Securing the load

Use chains & binders for heavy equipment and follow a four-point tie-down minimum with wheel chocks as needed. Protect paint/edges with pads.
