Bobcat Intros Four Tier 4, Non-DPF Excavators

E55Bobcat Company has introduced four Tier 4 excavators.

The E42, E45, E50 and E55 all include a non-DPF (diesel particulate filter) engine solution and each medium-sized M-Series machine features a forward-mount instrumentation system.

E42The Tier 4, non-DPF system was created through an ultra-low particulate combustion (ULPC) engine.

The ULPC came from a specially designed engine combustion chamber that reduces the amounts of particulate matter created during combustion.

The engine in the E50 and E55 machines will have a 12 percent increase in torque, which is produced over a wide range of engine rpm.

The excavators also feature a machine protection system that monitors, manages and shuts down the engine if needed. The protection system also monitors the engine coolant and oil temperatures to help prevent the fluids reaching a point where the machine has to be shut down.

The company has also implemented cold weather protection on the M-Series Tier 4 excavators. Anytime the engine temperature is too low, the loader will temporarily limit the maximum engine speed (rpm) to prevent premature component wear or failure.

Engine idle speed is also raised slightly to help the engine reach its operating temperature faster. As soon as the engine warms up to a predetermined temperature, the protection mechanism will deactivate. 

Three of the Tier 4 excavators — the E42, E45 and E55 — offer a clamp-ready, extendable-arm configuration that provides additional length when fully extended.

All the models feature an independent boom swing for offset operation as well as auto-shift travel. An auto-idle feature, which can be enabled at the operator’s discretion, automatically causes the engine to return to idle if the excavator’s functions are not used for four seconds.

Each of the machines can operate 13 Bobcat attachments, including augers, breakers, plate compactors, grading buckets, trenchers and rippers. The X-Change attachment mounting system is available on some models. Another option is the Hydraulic X-Change system, which uses hydraulic pins that retract and extend to change attachments.

Forward-mount instrumentation
A forward-mount instrumentation is being introduced with the E42, E45, E50 and E55.

The forward-mount system has put the input switches in front of the operator. The panel also offers multi-lingual functionality.

It also offers capabilities from analyzing user statistics, to integrated attachment controls, vitals and diagnostics. The new instrumentation system includes the functionality to capture individual fuel usage and real-time fuel consumption, as well as idle-time data.
