The Next Generation Cat® 374 excavator offers contractors high production, two times more structural durability, and up to 20 percent less maintenance costs than the industry leader it replaces, the 374F.
“A key to production is our new dedicated hydrostatic swing circuit,” said Brian Abbott, worldwide product manager for Cat large excavators. “The circuit enables regenerating swing brake energy and independent management of cylinder oil flow. What that means for owners and operators is higher operating efficiency and smoother, more predictable performance when multitasking with the excavator.”
Three modes of operation are available: Power, Smart, and ECO. Power mode is maximum power at all times. ECO mode lowers engine speed and cycle times while maintaining breakout force. Smart mode takes the guesswork out by automatically matching engine and hydraulic power to digging conditions, reducing fuel consumption and optimizing performance. Engine speed automatically lowers when hydraulic demand decreases, further reducing fuel usage.
The cooling system features a new on-demand fan that’s designed to operate only when required, saving fuel and ensuring maximum efficiency. An available auto reverse function assists with cleaning debris from the cooling cores — another plus for enhanced efficiency.
