Caterpillar 374 excavator has an operating weight of 158,200 pounds and is powered by a 485-horsepower Cat C15 diesel. Maximum digging depth is 28 feet 1 inch.
The Next Generation excavator has a dedicated hydrostatic swing circuit that enables regenerating swing brake energy and independent management of cylinder oil flow.
Operating modes on the Caterpillar 374 excavator include 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 automatically matches engine and hydraulic power to digging conditions.
The cooling system’s on-demand fan operates only when required, saving fuel. An available auto reverse function assists with cleaning debris from the cooling cores.
Caterpillar Next Gen technology
The Cat 374 excavator has a technology suite that includes Cat Payload and Cat Grade with 2D, which can be upgraded to Cat Grade with Advanced 2D or Cat Grade with 3D
Lift Assist helps prevent the excavator from tipping by calculating the weight of the actual load being lifted and comparing it to the excavator’s rated capability. Visual and auditory alerts show and tell the operator if the excavator is within a safe working range.
2D E-Fence prevents the excavator from moving outside operator-defined points, whether using a bucket or hammer. This helps protect the machine and other objects from damage and helps prevent operator fatigue by reducing over swinging and digging.
Auto Hammer Stop prevents unnecessary wear and tear on the attachment and machine. A warning message appears on the monitor after 15 seconds of continuous firing; the hammer will automatically stop after 30 seconds of continuous firing.
The optional Cat PL161 Attachment Locator makes finding attachments and other gear quick and easy. The excavator’s onboard Bluetooth reader or Cat App on a smart phone will locate the device automatically up to a distance of 300 feet.
Booms, sticks, and frames are twice as strong as those on the previous model. 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.
Cat 374 excavator maintenance costs
Extended and synchronized maintenance intervals contribute to the 374’s lower long-term costs. The new Cat air filter with an integrated pre-cleaner and primary and secondary filters provides double the dust-holding capacity of the previous design. The new Cat hydraulic return filter has a 3,000-hour service life: a 50 percent increase over previous filters. Fuel system filters are synchronized for service at 1,000 hours: a 100 percent increase over the previous filters.
The 374 offers a choice between a Deluxe and Premium cab. Performance-enhancing features like the front-facing control panel, keyless pushbutton start, and large touchscreen monitor with jog dial keys come standard.
Following are other cab amenities that are sure to please operators:
Tilt-up console that allows easy cab entry and exit.
Advanced viscous cab mounts that reduce vibration as much as 50 percent compared with previous models. Bluetooth integrated radio with USB ports for connecting and charging phones. Automatic climate control that maintains temperature settings regardless of ambient temperatures. Programmable joystick buttons that allow setting control patterns and hydraulic response rates, permitting machine operation to be tailored to individual preferences.
Large front, rear, and side windows along with standard rearview and right-hand side cameras to enhance visibility.
