Key Specs
With up to 10 percent more productivity than the model it replaces, the Cat® 340 is the best in its class for moving tons per hour. Add in the excavator’s low owning and operating costs and you will profit like nobody’s business.
More engine power, wider undercarriage, and heavy counterweight enable bigger payloads and best-in-class production.
Industry-leading fuel efficiency, long-life filters, and easy-access service points reduce downtime for increased production.
Available technology makes work simpler, safer, and more efficient.

While machines are designed to maximize operator visibility, it can be challenging to constantly monitor what is going on around them. Cat® Detect - People Detection for excavators is an intelligent vision camera system that can alert an operator when someone enters within a machine’s hazard zone.

Cat Grade with 2D helps excavator operators work up to 35% more efficiently in a wide variety of applications. Delivering real-time guidance for accurate vertical and horizontal control, Grade with 2D helps to ensure that cuts and fills are made to exact specifications – without under or overcutting.
Grade with 3D adds GNSS technology and RTK positioning guidance to simplify the grading process of complex designs often found on large infrastructure and commercial projects.
Cat Grade with Advanced 2D gives excavator operators the ability to input, edit, and grade simple two-dimensional designs by using real time bucket tip and elevation guidance provided by the system.
