Frequently Asked Questions (FAQ)

What is a lowbed trailer?

A lowbed trailer carries heavy/oversized machinery with a low deck height for tall loads.

Flatbed vs Lowbed — what's the difference?

Flatbed is a standard deck for general cargo; lowbed is much lower and built for heavy machinery.

How many axles do I need?

Depends on payload and local road rules. Common options are 2–4 axles; heavy haul can require more.

Mechanical vs Air suspension?

Mechanical (leaf spring) is robust and economical; air suspension offers ride comfort and adjustable height.

Distance from ground to the trailer kingpin center; crucial for tractor compatibility (e.g., 1100–1200 mm).
