Lag O-3-34 – three-axle heavy-duty trailer from the Belgian manufacturer in Bree: five versions with 34 to 40 t gross weight
LAG Trailers of Bree in the Belgian province of Limburg has built tank, silo and bulk vehicles since 1947 and is one of the leading manufacturers in the Benelux region in this segment. The O-3-34 range covers a three-axle version of the brand in the register; models such as O-3-34 CA, O-3-34 CP, O-3-34 CPBE and O-3-34 KA differ in body and equipment. The designation O-3-34 refers to the three-axle version with a gross weight of up to 40 t.

The register lists 5 versions with unladen weights from 5,760 to 8,220 kg, gross weights from 34,000 to 40,000 kg, lengths from 12,140 to 13,840 mm and widths from 2,440 to 2,550 mm.
Three-axle trailers in this weight class spread the load over more axles than the two-axle O-2-33 range, achieving higher permitted gross weights at a similar vehicle length; they are used in works and scheduled traffic, where LAG competes with specialised manufacturers such as Feldbinder and Magyar.
When buying used, check the frame and side members for cracks and corrosion, all three axles together with brakes and tyres for even wear, the drawbar and overrun brake, and, depending on the body, seals, valves or hatches; on three-axle trailers it is also worth checking the function and wear of the steering or lifting axle. On these heavy versions, the brake valves and the pneumatic system should also be checked.

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.
