The machine decides the trailer
“What is your best price for a lowbed trailer?” is a common opening question. Before comparing prices, I would ask what must travel on it. An excavator with its boom arranged for transport, a wheeled loader and a palletized load can create very different problems even at a similar gross weight.
Measure the cargo in its transport position: total weight, length, width, height and where that weight sits. Include attachments, buckets, counterweights or spare parts that will travel on the same trailer. A model name alone is not a final transport measurement.
Compare the loaded height, not just the empty deck
A lowbed has a lowered loading area. That can help when a tall machine would exceed the route height limit on a higher deck. A flatbed may work for lower cargo that can be loaded and secured appropriately. The useful calculation is the height of the complete loaded combination, including the tractor, trailer deck in its operating condition and the cargo in its transport position.
Ask for a dimensioned drawing showing deck height at the relevant load, usable deck length and width, gooseneck, ramps and tyre clearance. Manufacturers such as Goldhofer publish different loading heights for different low-loader designs, which is a reminder that “lowbed” is a category, not a universal dimension. A quoted height must belong to the proposed configuration.
How will the machine get on and off?
If the equipment drives onto the trailer, discuss its ground clearance, track or wheel spacing, approach angle, ramp width and ramp rating. A low deck does not by itself make a steep ramp suitable. If a crane loads the cargo, ramp design may matter less, while lifting access and tie-down layout may matter more.
Ask who will provide the loading equipment at origin and destination. Request the proposed loading method in writing; do not assume that ramps shown in a reference photo are included in your order.
Check loads and the tractor as one combination
A trailer brochure may list a technical payload, but the permitted road load can be lower once axle limits, tractor ratings, tyre ratings and the route are considered. Give the supplier the cargo weight distribution as well as the total weight. Ask for the proposed axle arrangement, suspension and fifth-wheel load, then have a qualified local operator verify the permitted combination.
If you already have a tractor, send its fifth-wheel height and rating, kingpin compatibility, braking and electrical details. The trailer needs to couple and brake correctly with that particular tractor. Also check turning clearance and any hydraulic or other auxiliary requirement.
Put comparable information in the quotation
Ask each supplier to quote against the same cargo brief. The offer should identify the trailer type, drawing revision, usable deck dimensions, structure and steel specification where agreed, axle and suspension arrangement, brakes, tyres, ramps, tie-down points, finish and documents. Mark any capacity or dimensions still awaiting engineering confirmation as pending.
For export, specify the quantity, destination port and whether you need FOB, CFR or CIF. Confirm whether the trailer ships assembled or disassembled, what reassembly is required and which costs remain at destination. A low headline price means little when one offer excludes ramps, tyres or freight that another includes.
A useful first message to RUICHI
“We need to move [machine and attachments], transport weight [weight], dimensions [L × W × H], on [route/country]. It will be loaded by [driving/crane]. Our tractor is [model and fifth-wheel details]. Please compare a lowbed and a suitable flatbed option, confirm the drawing, loading method and axle arrangement, and quote [quantity] units to [port] on [trade term].”
We can discuss a trailer configuration against that brief and provide a written proposal. Final ratings, dimensions, availability, delivery terms and import suitability need confirmation for the ordered trailer and the destination. If the machine dimensions or local route limits are unknown, settle those before treating either design as approved.
