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.

Typical jobs a lowbed handles

• Excavators, wheel loaders and dozers moving between sites.
• Mobile cranes relocating city to city.
• Transformers, tanks and process vessels going into industrial plants.
• Piling rigs and drilling equipment to infrastructure works.
• Any machine whose travelling height on a standard flatbed would exceed bridge clearance.

What the price depends on

Transport is quoted per job rather than from a price list, because the variables move independently:

• Weight and dimensions — which together set the trailer class and the number of axles.
• Distance and route — a run to Riyadh and a run inside Jeddah are different jobs.
• Permits — whether the load is within free-movement limits or needs authorisation.
• Escort requirements — pilot vehicles where width or length requires them.
• Loading method — ramps, a crane at either end, or driving the machine on under its own power.

Checklist before you book

1. Weigh the machine as it will travel, with attachments fitted or removed as agreed.
2. Measure travelling height, width and length — the height with the machine on the deck, not on the ground.
3. Confirm both sites can take a long trailer: entrance width, turning radius, surface.
4. Establish who loads at each end, and whether ramps or a crane are needed.
5. Send the dimensions early enough for permits and a route survey if the load needs them.

Frequently asked questions

How do I know whether I need a lowbed or a flatbed?

Measure the total travelling height with the machine loaded. If that figure clears the bridges on the route, a flatbed is faster and cheaper. If it does not, the low deck of a lowbed is what gets you under them.

How much notice do you need?

For a straightforward move within free-movement limits, short notice is usually workable. Anything needing a permit or a route survey should be booked several days ahead, because the authorisation is the long pole, not the truck.

Can you move equipment between cities?

Yes — inter-city relocation is routine, from our Jeddah base to sites across the Kingdom. Distance is one of the inputs to the quotation rather than a barrier.
