Lag O-3-40 – heavy low-loader range from the Dutch specialist: 10 versions, unladen weight from 4,900 to 9,350 kg, gross weight from 40,000 to 42,000 kg, lengths up to 14,040 mm
Lag is a Dutch manufacturer specialising in low-loaders and heavy-haulage semi-trailers. The O-3-40 range brings together a group of versions in the register, whose type designation combines a code and a numeric string, extended by a two- or three-digit suffix for the individual variant.

The register lists here 10 versions with unladen weights from 4,900 to 9,350 kg and a gross weight from 40,000 to 42,000 kg. Lengths range from 10,370 to 14,040 mm, and widths from 2,470 to 2,550 mm.
With a gross weight at the European upper limit for articulated combinations and a comparatively low unladen weight, the range aims for maximum payload in heavy-goods transport, for example construction machinery, steel structural parts or industrial plant. Low-loaders of this class usually work with specialised tractor units and are a fixed part of the European heavy and abnormal-load haulage trade.
When buying a used low-loader of this class, check above all the frame and reinforcements around the load bed (cracks, deformation from overloading), the condition of the axles, steering axles and braking system, and, on lowering versions, the hydraulics. Spare parts for the chassis and axles are available through the general semi-trailer parts trade, while specific low-loader components are best sourced from Lag directly.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
