With changes to manufacturing standard EN474 2022: part 6 due to become effective from February 2025, Thwaites has developed an alternative solution to ensure compliance and keep operators safe, the ROPS+.

The standard refers to front mounted dumpers, with an operating mass of over 3,500 kg and under 4,500kg.  The standard states that these machines shall be provided with an additional means, to prevent the operator from being ejected from the overall dimensions of the machine.

Thwaites dumpers in the 1-tonne to 4.5-tonne range will be below the threshold and unaffected by the new standard. Dumpers in the 6-tonne and 9-tonne range however will be affected. To comply with the standard, the 9-tonne Front Tip dumper will be offered exclusively fully cabbed only.


The 6-tonne Power Swivel and Front Tip dumpers will be offered with two fully compliant solution options, namely:

Option 1: Cabbed Dumper
Option 2: ROPS+

ROPS+ is an extension of the established Roll Over Protection System. Made from the same high tensile steel, the wrap around design places the operator in the optimum position to minimise risk, should a machine tip or roll over occur.
