Next-Generation Caterpillar 374 Excavator Provides Increased Durability & Efficiency
Featuring a new dedicated hydrostatic swing circuit and enhanced structural durability, Caterpillar’s new 374 excavator offers several improvements over the model it replaces, Cat’s 374F. “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.”
Twice As Strong
Cat says the booms, sticks, and frames on the latest 374 are twice as strong as those on the previous model. In particular, booms have increased top and bottom plate thickness; sticks have increased side, bottom, and bracket plate thickness; and frames have increased base frame and counterweight mounting plate thickness. Additionally, Cat built reinforcements into the car body, track link, track rollers, and boom, stick, and bucket cylinders to ensure long-term performance.
Maximum Power When You Need It
The new Cat 374 excavators offers three modes of operation: Power, Smart, and ECO. Power mode is maximum power at all times, while the ECO mode lowers engine speed and cycle times while maintaining breakout force. The Smart mode automatically matches engine and hydraulic power to digging conditions, reducing fuel consumption and optimizing performance. Engine speed is also automatically lowered when hydraulic demand decreases, further reducing fuel usage. Factory-installed technology, such as Cat Payload, Cat Grade, Lift Assist, and Cat Product Link, also help operators to optimize performance and efficiency.
