Caterpillar debuted the 308CR fixed-boom mini excavator at this 12 months’s Global of Concrete in Las Vegas, changing its 307.5 with extra hydraulic energy and potency.
As the most recent addition to Cat’s 8-metric-class lineup, the 308CR brings a brand new compact-radius design with 67% much less overhang when the use of the 550-pound counterweight and 61% much less with the 1,100-pound counterweight.

Beneath the hood, a 69-horsepower Cat C2.8 Turbo (very similar to Cat’s higher mini excavators) is provided with auto idle, auto engine shutdown and a variable displacement pump for hydraulics. The 308CR’s working weight is available in at 18,659 kilos.
Caterpillar greater digging intensity to fifteen ft 5 inches and most succeed in to 22 ft 8 inch within the long-stick configuration. Minimal-maximum configuration elevate capacities have additionally greater when working over the entrance with blade down and over the aspect.
Greg Worley, marketplace skilled at Caterpillar, says the 308CR meshes neatly with the rising pattern of city redevelopment.
“We are doing an increasing number of brownfield construction,” Worley says. “Principally, we are going again in redeveloping or filling within the areas in urbanized spaces; [there’s] much less inexperienced building happening in this day and age.”
“So whilst you move into those urbanized spaces, you want as a lot energy efficiency and capacity within the gadget’s smallest bundle imaginable,” he continues. “In order that’s why transferring from an ordinary tail swing gadget within the 8-ton platform with a set increase to that compact radius is essential as we get extra completed in those smaller, tighter environments.”
Excavator Highlights

In comparison to the 307.5, different upgrades at the 308CR come with greater monitor width of seven ft 7 inches and greater undercarriage duration of 9 ft 5 inches.
Within the sealed and pressurized cab, operators will in finding:
- Subsequent-gen observe with customizable personal tastes.
- Same old Cat stick steer with button activated switching from lever and paddle to joystick keep watch over.
- Fluorescent seatbelt. (A seatbelt reminder device is not obligatory.)
- Cruise keep watch over choices.
- Progressed air con.
- Adjustable wrist rests.
- Suspension seat.
The 308CR options ground-level regimen test issues with grouped carrier issues, a back-up digital camera, aspect digital camera and paintings lighting fixtures.
To be had monitor choices at the 308CR come with rubber belt, metal monitor and metal monitor with rubber pad.
Operators received’t need to replace their paintings software lineup, because the 308CR gives the similar pin sizing because the 307.5. The excavator’s load sensing hydraulics, with the variable displacement piston pump, be offering 44 gallons in keeping with minute of oil waft. The principle auxiliary circuit pumps 35 gallons in keeping with minute, and the second one auxiliary circuit’s most waft is available in at 9 gallons in keeping with minute.
More than one Tech Choices
Contractors can make a choice from two tool programs from the manufacturing facility, which will also be added as a box improve package:
- Cat Point out — Provides visible and audible signs for figuring out bucket placement relative to focus on grade and will also be programed to a flat grade or slope. It is best fitted to duties like footings, septic methods, foundations and slope paintings.
- Cat E-Fence — Restrains the 308CR’s movement to preset E-Ceiling and E-Flooring obstacles when running in tight areas, together with underneath energy strains, ceilings and bushes and above fiberoptic cables and utilities. An E-Wall atmosphere too can confine vary of movement in entrance of the 308CR.
Further generation choices for the 308CR come with the Laser Catcher for making a constant reference level around the jobsite, the aftermarket Cat Grade automatics for atmosphere digging and leveling parameters for easy and sophisticated designs, and Cat Grade three-D for attaining real-time kinematic positioning steerage on advanced jobs.
