100 – 150 Ton Heavy Haul Lowbed

At 100 tons a fixed-axle lowbed still works — a 6+ axle hydraulic self-steering bogie under a Q420B box girder covers large excavators, mining shovels and mid-size crane counterweight sections. This is the top of our standard lowbed range.

Above roughly 120-150 tons, the search terms usually describe a load that no longer suits a single fixed-frame chassis. At that point a hydraulic modular trailer — axle lines that couple side-by-side or end-to-end and adjust deck height under load — is the correct and legal way to move it, not a stretched lowbed.

Where a Fixed-Axle Lowbed Stops Making Sense

A fixed-axle lowbed's main beam is engineered for one deck length and one axle spread. Push the payload past around 100-120 tons and the beam, the kingpin load and the axle count all need to grow together — at some point the trailer becomes a custom heavy-haul build in every way except name, and a modular trailer does the same job for less money because its axle lines and deck modules are standardized and reusable across different loads.

If your load is 100-110 tons and fits on a conventional deck, a 6+ axle lowbed is still the right and cheaper answer. If it's genuinely oversized — wide, long, or pushing 130+ tons — send us the dimensions and axle weights and we'll tell you honestly which one you need.

6+ Axle Lowbed Specification

At 100 tons the standard build runs a hydraulic self-steering bogie across 6 or more 13-ton axles, a Q420B high-strength steel box girder in place of the Q345B used on lighter ratings, and a hydraulic detachable gooseneck as standard rather than an option — fixed-neck builds are rare at this payload because the loading and unloading logistics favor ground-level access.

When It's a Modular Trailer Instead

A hydraulic modular trailer couples axle lines behind a tractor unit — up to 40 tons per line — with independent hydraulic suspension that keeps the deck level over ramps and uneven ground, plus hydraulic height adjustment. Lines join side-by-side for wide loads (transformers, generator sets) or end-to-end for long ones (bridge girders, wind turbine sections). It scales from 2 to 12+ lines, so the same equipment handles a 130 ton transformer this month and a 300 ton press next. See the full modular trailer range.
