Not only does Marven offer heavy duty Level 3 ROPS but we have the ability to offer lighter and cheaper rollover option. This being our NDLOVU Internal. This structure is fitted into the cab of the vehicle and can only handle a single roll at a very low speed. Depending on the mine and who it runs by, defines which ROPS you will be required to have. You can speak to one of our experienced sales people about mine requirements.
