The Cat 340 UHD – which stands for Ultra High Demolition – is a new demolition excavator from Cat. The new tallboy has a pin height that is 13% higher than the 340F UHD, allowing it to demolish structures up to eight stories tall. Another benefit is that the 340 UHD has a coupling system that allows you to switch between two UHD fronts and the shorter retrofit booms and sticks in as little as 15 minutes without the use of any special tools. Cat also worked on making the new demolition excavator more transportable. In the transport mode, a hydraulically actuated variable gauge from 9 ft 10 inches to 13 ft 4 inches for stability in the working configuration. The UHD boom transport height can be reduced to less than 9 ft 10 inches by using an optional one-piece cradle. The new 340 UHD allows for the use of Cat couplers on the sticks to increase machine versatility and productivity. There are three stick lengths available: 9 ft 2 inches, 10 ft 6 inches, and 12 ft 10 inches. The machine's maximum digging depth is 24 ft 3 inches. The hydraulic boom lines on the UHD are easily connected and disconnected by hand and without the use of any special tools. For high-productivity truck loading or low-level demolition work, contractors can choose between one- and two-piece boom options. When working with the one-piece retrofit boom, Standard Cat Payload provides on-the-go weighing and real-time payload estimates, allowing operators to achieve precise load targets. Cat increased the seat size by 5% and added a tilt-up console on the left side for easier entry and exit. On the monitor, customised, programmable settings and joystick button controls can be saved based on operator ID. Image Source
