Caterpillar has expanded its range of Next Generation mini hydraulic excavators with the addition of six new models in the 7- to-10-ton category. The new models provide a selection of basic configurations, allowing customers to choose the machine that works most efficiently in applications routinely encountered.
As with all Cat Next Generation mini excavators, the new models feature heavy-duty main structures, fuel efficient engines, load sensing hydraulics, spacious cabs, and the exclusive Cat Stick-Steer system.
The new-model lineup includes the 307.5, a standard tail swing model with a fixed boom; 308 CR, a compact radius model with a swing boom; 308 CR VAB, featuring a variable angle (two-piece) swing boom; 309 CR, a new model in the mini range featuring a compact radius, swing boom, and high flow auxiliary hydraulics; 309 CR VAB, which expands the 309 CR's capability with a variable angle boom; and 310, also new to the range, featuring a fixed boom, standard tail swing, and twin blade cylinders for handling heavy-duty dozing chores.
The new models range in maximum operating weight from 18,152 to 22,447 lbs. and in standard dig depths from 13 feet 5 inches to 17 feet. Three models — 307.5, 308 CR, and 309 CR — are available with a long-stick option that increases dig depth by approximately 22 inches. The variable angle boom, available with the 308 CR VAB and 309 CR VAB, enhances digging capability in congested work areas. Powering the 307.5 is the Cat C2.4 turbo diesel engine rated at 55.9 net hp; the five larger models use the Cat C3.3 diesel engine rated at 70.3 net hp.
