Gruen – other models: the collective page of tar and hot-asphalt boiler trailers for road building outside the named ranges, RK and RVK series, 730 to 2,250 kg unladen weight, up to 3,500 kg gross weight
This page gathers the trailers the register lists under the name Gruen outside the named ranges. The model names – Teerkocher, RK and RVK with an attached number for the boiler size – point to road-building trailers used as towed boilers for heating jointing compound and hot-laid asphalt; the RK and RVK ranges differ in boiler size and extra equipment, such as the Sonder suffix on the RK 250 Sonder; the plainly numbered 601 and 901 models denote simpler base versions without this suffix.

The register lists here 10 versions with unladen weights from 730 to 2,250 kg, gross weights from 935 to 3,500 kg and widths from 1,580 to 2,050 mm.
As towed working equipment rather than classic transport trailers, tar-boiler trailers are common in road and civil engineering, where they bring jointing compound, bitumen or hot asphalt up to working temperature on site; the unladen weight stays deliberately low so that even smaller tow vehicles can bring the equipment to the worksite; heating time also varies with boiler size, which is why construction firms often keep several sizes side by side in their fleet.
When buying used, the condition of the boiler, burner and thermostat matter most, along with the tightness of the welds, the condition of the chassis, brakes and lighting, and the date of the last burner inspection; spare parts for the boiler and burner are available from dealers specialising in bitumen equipment.

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.
