Cummins has launched new engine power take-off (PTO) capabilities for its B6.7 and L9 Performance Series Power Units that could help support underground mining equipment, as well as crushing and screening units.
Launched at Hillhead 2018, Cummins’ power units are available from 75-503 kW, and delivered as a complete and ready-made package. This comprises an engine, exhaust after-treatment system, radiator, and cooling system, plus auxiliaries such as mounting feet, hoses and an air cleaner.
More than 60% of the content is pre-approved, making the machine integration process simpler and quicker, according to the company.
Jeremy Harsin – Cummins Off-Highway Marketing Director – said: “Our Performance Series power units offer a flexible drop-in solution for manufacturers. The high-power density of our engines enables them to deliver high machine capability for hard-working applications such as crushing, screening and pumping.”
Examples of installations to date include the L9 Power Units powering Anaconda Equipment International’s new J12 and I12 mobile crushing machines.
“To increase the flexibility and capability of the power units, we are integrating new single and dual rear-engine power take-offs (REPTO),” Harsin said. “These complement their standard PTO capability used for items such as hydraulic pumps. We are also making these available on the base engines without the pack.”
As an example, fitted with the dual REPTO, the L9 will have a total drive capability of 560 Nm. This will make the engine capable of driving additional pumping capability through SAE B 2 and 4 bolt mounts, according to the company. Integrated into the flywheel housing, the dual REPTO is compact and has a minimal impact on engine packaging. Added weight is around 100 kg.
“For equipment manufacturers, they have the ability to efficiently drive more from the engine without the need for additional aftermarket systems,” Harsin explained. “This would support driving of hydraulic pumps for all sorts of machine functions from steering systems to fans, etc. It will reduce installation costs and complexity, for a more integrated solution.”
