With around 200 safety-relevant tests on cabs per annum, DLG TestService ensures that operators and drivers of tractors, earth-moving machines, forklift trucks and trucks are provided with optimum protection in the event of an accident. With its international experience and expert network, DLG is your service partner for all testing requirements in the area of cabs and driver safety – far beyond the bounds of agricultural machinery.
The test laboratory is accredited in accordance with ISO 17025 and designated as a technical service by the German Federal Motor Transport Authority in all areas relevant to cab testing. DLG TestService is also designated as an official national test body by the OECD. Full approval processing is carried out with the German Federal Motor Transport Authority or the OECD coordination office as required.
Tests on ROPS – Roll-Over Protective Structures (rollover protection)
The stability of the cabin during rollover is tested. The rollover protection structures must be designed in such a way that a defined survival space is maintained in the event of a single rollover.
Testing standards
- VO (EU) 1322/2014
- ISO 3471, ISO 8082, ISO 12117-2, ISO 21299
- OECD Code (3), 4, 6, 7, 8, 9
Tests on lorry cabs
Truck cabins are tested on a special test bench. These tests, which simulate a frontal collision or rollover, are carried out dynamically using various pendulums defined in the UN/ECE Regulation No. 29.03 test standard. From 30 January 2021, all trucks (vehicle classes N1, N2 and N3) must meet the requirements of UNECE R 29.03 when they are placed on the market.
Regulation
- UN/ECE-Regelung Nr. 29
Strength testing of rear underrun protection devices
As a technical service appointed by the Federal Motor Transport Authority, DLG TestService offers strength testing for rear underrun protection devices.
Since 1 September 2021, all trucks and trailers in classes N and O must be equipped with rear underrun protection that has been tested in accordance with amendment series 03 to UN/ECE Regulation No. 58. We carry out the relevant tests at the DLG Test Centre in Groß-Umstadt.
For agricultural and forestry trailers in class R, the rear underrun protection is tested in accordance with Regulation (EU) 2015/208 Annex XXVI. The EU regulation essentially corresponds to the 02 series of amendments to UN/ECE Regulation No. 58.
Development-related testing for cabs
As an independent third party, DLG TestService offers manufacturers confidential R&D testing services in the field of driver cabs. With the expertise of our specialists and our comprehensive testing infrastructure, we can carry out targeted trials and tests in accordance with manufacturer-specific specifications and requirements.
Additional development benefit for manufacturers
Our various test benches for determining driver seat safety are powerful tools that enable cabin manufacturers to carry out development-related tests exactly according to their specifications.
As part of our development activities, we also offer services with additional measurement technology, such as acceleration measurements, and can determine stress conditions using strain gauges.

Special features of cabin tests
ROPS tests up to 100 tonnes
The DLG Test Centre has two ROPS test benches that can be used to test cabins for machines with a total mass of up to around 100 tonnes. Test forces of 1,500 kN (horizontal) and 2,000 kN (vertical) are available for this purpose.
XXL cabins put to the test
Particularly large cabins are also tested. The maximum test specimen dimensions are 5,000 × 5,000 × 3,700 mm (L × W × H). The cabins are usually delivered on the machine frame and fixed to the clamping plate.
Tests at sub-zero temperatures
All tests can also be carried out at –18 °C on request.
