Cat® 345 Hydraulic Excavator
Request A Price Find DealerKey Specs
The Cat® 345 is a multitasking master that offers a balance of dependable production, operator-oriented features, and low owning and operating costs. Equipped with the reliable Cat C9.3B 258kW engine and two power modes to help manage fuel consumption for specific applications such as truck loading and trenching, this machine is compatible with multiple Cat attachments and a smart choice for operations where consistency and performance are priorities.
Smart Mode automatically adjusts power to help operators achieve the highest fuel efficiency – less power for tasks such as swinging and more power for digging.
Excavators typically work on rugged and challenging sites. The 345's cab safety and convenience features help protect operators from fatigue, stresses, sounds, and temperatures on the job.
Cat® Next Generation Excavators share common parts, extended and synchronized service intervals, exceptional customer service, and superior product support.
