Case says that they are cleaner, stronger, more efficient and cheaper to run than the previous B Series excavator models.
The new models are the CX130C, CX160C, CX180C, CX210C, CX210C Long Reach, CX470C and CX470C ME.
The Tier 4 Interim compliant engines in the seven machines use cooled exhaust gas recirculation (CEGR) to provide a cleaner burn. Customers with B Series models will have already seen up to a 20% fuel improvement over older models. With the C Series excavators they can expect up to a further 10% efficiency improvement.
The Case Intelligent Hydraulic System incorporates five energy saving systems. Boom Energy Save lowers engine revs during boom lower and swing operations, while the Auto Energy Save system cuts engine revs when the joystick control levers are inactive.
Swing Relief Control manages the hydraulic power distribution at the start of a slewing operation to provide the most efficient use of hydraulic flow and pressure. Spool Stroke Control automatically adjusts the hydraulic pressure during digging operations. Lastly, Idle Shutdown turns the engine off after a preset time has elapsed.
Case claims that cycle times on the new C Series models are up to 5% faster than on their B Series predecessors, though with smoother and easier controls. Lift capacity is increased by around 6%, depending on model. A full range of buckets and attachments is available for the C Series models. The revised line of excavation buckets are all available with the Case SmartFit bucket tooth system, allowing rapid change of bucket teeth without the need to hammer out pins.
