Caterpillar Upgrades the 374 Excavator
The upgrades on the new 484-horsepower Cat 374 excavator focus on the things that matter in demanding conditions: high loading production, a 20% reduction in maintenance costs, and a beefed-up boom, stick, and frame designed to deliver twice the durability of the previous 374F.
In fact, Cat says the 374 can now load up to 33 Cat 772 trucks per hour working at 100% job site efficiency. (This assumes a 6.5-cubic-yard bucket working in 1.6-cubic-meter material density.)

Using a new dedicated hydrostatic swing circuit, the 374 can regenerate swing brake energy and independently manage cylinder oil flow, Cat says. This circuit has a dedicated bi-directional swing pump, swing motors, charge pump, and charge accumulator. The swing pump supplies oil to the swing motor; the charge pump and accumulator prevent cavitation (air bubbles) and overheating.
