Caterpillar 308E2 Mini Excavator with VAB

March 18, 2016

The Cat 308E2 mini hydraulic excavator is now available in a variable-angle-boom (VAB) configuration that provides an expanded working envelope and increased application flexibility. The VAB configuration, which adds another hydraulically controlled boom section between the machine’s main boom and stick, provides a maximum dig depth of 169 inches and extends the 308E2’s maximum reach by 30 inches, to a total of 306 inches, compared with the standard boom-and-stick configuration. Dump clearance is extended by 56 inches to 239 inches. The VAB also allows the 308E2 to work closer to the blade and tracks, resulting in added lift capacity when working in confined areas.

Using a 65-horseower Cat C3.3B engine and a load-sensing hydraulic system that delivers flows to 39.6 gpm, the 308E2 features a compact-radius design that limits tail overhang when working over the side to 11 inches. For applications requiring added stability and lift capability, an available added counterweight extends overhang modestly, to 16 inches.  

The operator’s station, features an air- suspension/heated seat, adjustable wrist rests, and ergonomic joysticks. The Cat COMPASS monitor includes a pass-code-protected security system, adjustable auxiliary-flow control, site reference system, and rearview camera. The operator’s station is ROPS certified and incorporates the Cat interlock system, which prevents hydraulic functions when the safety bar is raised. Additional safety features include an automatic swing brake, retractable seatbelt, and travel alarm (optional in Europe).

The 308E2’s undercarriage can be fitted with a rubber belt, steel tracks, or steel tracks with rubber pads. Available mechanical or hydraulic quick couplers expand the 308E2’s versatility with a range of Cat work tools, and a thumb-ready stick is standard.
