(9) Every truck and loader shall have a nameplate securely fixed to the cab showing the serial number of the unit, the maximum rated load capacity and if in excess of 45,000 kilograms (100,000 lbs) gross vehicle weight, shall show the maximum allowable speeds at the gross vehicle weight that the retarder or braking system is designed to accommodate when travelling on the maximum downgrade on which the vehicle is designed to operate. Rollover (10) All new loaders, graders, scrapers, tractors, compactors, rollers, rough terrain forklifts, bulldozers and off-highway haulage trucks and any other new or used equipment, when required by the Inspector shall be equipped with a rollover 113 protective structure (ROPS) and seat belts that conform to an internationally acceptable standard.
