Equipment Spotlight: Reduced/Zero Tail Swing Excavators
Reduced/zero tail swing excavators by Bobcat, Sany America, John Deere Construction, Hitachi, Volvo, Case, Doosan Infracore Construction America, Caterpillar, Hyundai Construction Equipment Americas and Kubota.
Bobcat
The new Bobcat zero tail swing Tier 4 E45, with a non-DPF (diesel particulate filter) engine solution, features a machine protection system that monitors, manages and shuts down the engine if needed. This system monitors engine coolant and oil temperatures and will manage engine systems to reduce the possibility of these fluids reaching a point where the machine has to be shut down. This minimizes potential damage to the engine, stops unnecessary engine wear and keeps operators working. 866.823.7898, bobcatadvantage.com
