Published 27/12, 2019 at 17:14

Designed with an improved customer experience in mind, the new Cat 306 CR mini excavator is built to exceed customer expectations with strong performance, enhanced operator experience and simplified maintenance with extended service intervals.

With standard exclusive features, it provides a great value for customers and boasts what is said to be industry leading performance.

The new mini excavator features heavy duty main structures, a fuel efficient engine, load sensing hydraulics, spacious cab and exclusive ‘Cat Stick Steer’ system. It shares a similar control layout and common components with the full line of Cat Next Generation mini excavators to simplify training, offering quick adaptation for operation and lower owning and operating costs. With its long stick option, the Cat 306 CR delivers a maximum dig depth of 4,110mm and 7,175 kg maximum operating weight when equipped with the sealed and pressurised cab. 

Offering big performance features in a mini excavator format, the Cat 306 CR delivers what is said by the company to be class leading lift performance of up to 3,555kg at a 3m radius, whilst enhanced uphill swing torque and increased cycle times provide greater productivity and efficiency. The machine’s fuel saving, load sensing hydraulic system, with an electronically controlled variable displacement piston pump, generates 151l/min hydraulic oil flow. It also offers the hydraulic capacity for increased travel performance and higher digging forces. 

The high flow rate of 90l/min to the auxiliary circuit enables operation of even the most demanding hydro mechanical attachments. Complete with quick disconnect lines, the standard auxiliary hydraulic system provides one way, two way and continuous flow. The Cat C2.4 turbo diesel engine rated at 41.7kW powers the new mini excavator and meets EU Stage V emission standards. It features a power dense design and delivers consistent performance through a wide speed range. Automatic engine idle and shutdown features help to save on fuel consumption.

The new mini hydraulic excavator shares common components with models in the Cat mini excavator line to lower repair cost, decrease service time and reduce repair parts inventory. Major machine structures – upper and lower frames, track frames, boom and sick – are modelled after its larger Cat excavator counterparts for long term durability. Ground level access to maintenance checkpoints offers convenient access, while enhancing worker safety. Industry leading grease intervals help to shorten the daily service routine, whilst extended filter service life means the Cat 306 CR mini excavator spends less time in the service shop for routine maintenance.
