Lag O-3-42 – range from the Belgian maker LAG of Bree: ten versions of tank and silo semi-trailers, 4,500 to 11,000 kg unladen weight, 27 to 44 tonnes gross weight
Lag O-3-42 denotes a range of tank and silo semi-trailers from the Belgian manufacturer LAG of Bree, which specialises in trailers for transporting liquid and bulk goods. The model list shows a base version plus numerous execution variants such as 01, 02, CT, FR, KA, KC, PT and T, which differ in equipment and body detail but follow the same base design, sharing the same chassis and running gear.

The register lists 10 versions with unladen weights from 4,500 to 11,000 kg at gross weights from 27,000 to 44,000 kg. Lengths range from 11,000 to 14,040 mm, widths from 2,500 to 2,600 mm.
With gross weights close to the ceiling customary in Europe for three-axle semi-trailers, the O-3-42 range is built for classic articulated operation in tank and silo transport and competes with further Belgian, Dutch and German makers of liquid- and bulk-goods trailers; such tankers commonly serve chemical, food and agricultural bulk haulage across the European road network.
When buying a used trailer of this range, the condition of the tank or silo shell, seals and discharge valves, rust on the frame, axle mounts and kingpin plate, and the function of the brakes and landing legs all matter. On larger-volume versions, the interior coating and cleaning access points are also worth checking; spare parts run through the manufacturer and specialist tank-trailer workshops.

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.
