The next-generation Cat 374 excavator offers operators high production, two times more structural durability, and up to 20 percent less maintenance costs than the 374F, according to Caterpillar.

“A key to production is our new dedicated hydrostatic swing circuit,” says 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.

According to Caterpillar, 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, the company says.

“An additional key to production is simple, easy-to-use technology,” Abbott says. “We make it available as standard equipment. In fact, the 374 has the industry’s most comprehensive offering of factory-installed technology in its size class – all to take an owner’s operating efficiency to a much higher level.”

Cat Payload, meanwhile, helps operators increase loading efficiency with on-the-go weighing, the company says. Real-time payload estimates can be calculated without swinging to help prevent overloading and underloading trucks.
