Demolition Excavator with the Largest Work Tools for 6 to 7 Story Work

The Cat® 340 UHD provides optimum machine solutions for building demolition up to 8 stories. With its unique coupling system, you can switch between two lengths of Ultra High Demolition fronts and two types of Retrofit booms and sticks with no special tools in 15 minutes. You simply won’t find a better 50-ton class choice for demolition.

Benefits

MAXIMIZE MACHINE UTILIZATION

Hydraulic quick disconnect requires no tools to swap booms in 15 minutes; choose your front - work up to 22 m with a 3.7 T tool (72 ft with 8,160 lb tool) or up to 25 m with a 3.3 T tool (82 ft with 7,275 lb tool) front or basement to 2 story work and truckloading with Retrofit.

MAXIMIZE JOBSITE EFFICIENCY

Variable gauge undercarriage provides excellent stability extended and ease of transportation retracted.

COMFORT & SAFETY

Deluxe cab tilts 30 degrees for a more ergonomic operator station includes P5A high resistance glass for safety and premium seat for comfort while 254 mm (10 in) color touchscreen indicates easy to read stability monitoring system information.
