As customer needs change, companies like Caterpillar are developing innovative new models to meet those needs. Emissions regulations, shrinking labor supply, transportation requirements and tighter project bids are just a few of the many forces driving new technology at Caterpillar.
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. While providing a maximum dig depth of 169 in. (4 290 mm), the VAB extends the 308E2’s maximum reach by 30 in. (760 mm) to a total of 306 in. (7 780 mm), compared with the standard boom-and-stick configuration; dump clearance is extended by 56 in. (1 410 mm) to 239 in. (6 080 mm). In addition, the VAB allows the 308E2 to work closer to the blade and tracks, resulting in added lift capacity when working in confined areas.
Caterpillar has added the model 300.9D VPS (Versatile Power System) to the Cat range of mini hydraulic excavators. The versatile design of the 300.9D VPS benefits both the owner/operator and the rental company by allowing the machine—in conjunction with its separate hydraulic power unit—to work either with its diesel engine or from a remote electrical power source, with no loss of performance. Having an electrical drive system remote from the machine enhances utilization and rental options. The 300.9D VPS can be rented alone for regular applications—or with the hydraulic power unit when the job requires low noise and zero emission.
The Cat 304.5E2 XTC mini hydraulic excavator is the first model in the Xtra Tool Carrier (XTC) lineup. The machine has an innovative skid steer coupler interface for added versatility and work tool integration. This manual coupler allows for use of compact loader tools including: general purpose bucket, multi-purpose bucket, forks, dozer blade, brooms, power box rakes and trenchers. Coupler operation is controlled through a flick of the XTC switch on the right hand console in the operator station, and then the standard right hand joystick becomes your loader. The 304.5E2 XTC allows operators to achieve improved productivity in material carrying applications, and also allows for reduced backfilling times.
