374 Hydraulic Excavator

374 Hydraulic Excavator

Cat® 374– More Production and Durability with Less Maintenance
The unique capabilities and features of the Cat® 374 improve your operation when it comes to efficiency, production, and safety. With 10% more swing torque and a hydrostatic swing circuit, the 374 recovers energy while swinging and can load up to 33 40-ton trucks an hour. Equipped with the SD5.0m3 bucket, this machine can load a 70-ton off-road truck in 7 passes. Built for durability, the 374 is structurally sound with reinforced track rollers, booms, sticks upper and lower frames. Reduced hydraulic oil capacity, improved filters with longer service intervals, and an integrated auto-lube-ready system save you up to 20% in maintenance costs. The 374 offers the latest technology and data, allowing you to make informed, smart decisions in a competitive industry. Improved all-around visibility helps keep your jobsite and employees safe while enhancing productivity.
