Cum­mins has an­nounced that its B6.7 and L9 ‘per­for­mance se­ries’ power units will fea­ture new en­gine power take-off (PTO) ca­pa­bil­i­ties to sup­port key ap­pli­ca­tions such as cranes, crush­ers and screen­ers.

Cum­mins’ power units are avail­able from 75 – 503kw (100 – 675hp) de­liv­ered as a com­plete and ready-made pack­age. This com­prises an en­gine, ex­haust af­tertreat­ment 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.

Jeremy Harsin, off-high­way mar­ket­ing di­rec­tor, Cum­mins, 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’s new J12 and I12 crush­ing ma­chines. The B6.7 ver­sion is avail­able with Ban­dit in their In­tim­ida­tor 20XP tree chip­per plus NLB Corp’s water jet­ting sys­tems.

“To in­crease the flex­i­bil­ity and ca­pa­bil­ity of the power units, we are in­te­grat­ing new sin­gle and dual rear-en­gine power take-offs (REPTO). 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,” added Harsin.

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. In­te­grated into the fly­wheel hous­ing the dual REPTO is com­pact and has a min­i­mal im­pact on en­gine pack­ag­ing. Added weight is ap­prox­i­mately 100kg.

“For equip­ment man­u­fac­tur­ers, they have the abil­ity to ef­fi­ciently drive more from the en­gine with­out the need for ad­di­tional after­mar­ket sys­tems. 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,” con­cluded Harsin.
