- Stage V engines tested under extreme conditions
- Close technology partnership in emission-related decisions
- More than 110,000 operating hours completed in field trials
Bell Equipment, the international specialist for articulated dump trucks, recently received the first six Series 1000 – 1500 MTU engines from Rolls-Royce that meet the new EU Stage V emission standard. The engines cover a power range from 170 to 430 kW. This had been preceded by a test phase of several years under the most adverse operating conditions in order to ensure the trucks would be guaranteed a reliable, cost-effective upgrade. To this end, MTU’s off-road engine series were optimised to comply with the emission standard and a new exhaust aftertreatment system introduced.
Bell Equipment, one of the world’s leading manufacturers of transport vehicles and haulage tractors for the mining, civil engineering and road construction industries, specialises in articulated dump trucks. In preparation for the more stringent emission requirements, Rolls-Royce had made two Stage V prototypes available to Bell for field trials in 2016 – a 260 kW MTU 6R 1000 engine and a 430 kW 6R 1500 were successfully tested in the hot, dusty climate of South Africa and for the tough conditions encountered at extreme altitudes of up to 3,000 metres.
