I DA U N I V E R S A L N ove m b e r - D e ce m b e r 2 0 2 1 40 NUTS & BOLTS continued from page 37 Cat has unveiled a new demolition excavator, the Cat 340 UHD – as in, Ultra High Demolition. e new tall boy boasts a pin height 13 percent higher than the 340F UHD, giving it the ability to perform demoli- tion on buildings as high as eight stories. Another plus: the 340 UHD has a coupling system that enables you to switch between two UHD fronts and the shorter retrofi t booms and sticks with no special tools in as little as 15 minutes. " is is a purpose- built, dedicated demoli- tion machine," says James Cole, product application specialist. "We are not just throwing a long front on a standard excavator. It has a reinforced frame, a heavier counterweight and the best working weight in the industry in its size class." Cat also spent time engineering the new demoli- tion excavator to be easier to transport. A hydrauli- cally actuated variable gauge undercarriage extends from 9 feet, 10 inches in the transport mode to 13 feet, 4 inches for stability in the working confi g- uration. And an optional one-piece cradle for the boom can be used to reduce the UHD boom transport height to less than 9 feet, 10 inches. Multiple Boom, Stick Options e new 340 UHD allows for the sticks to be confi g- ured with Cat couplers to optimize machine versatility and productivity. Two front Demolish 8-Story Buildings with New Cat 340 UHD Excavator Purpose-built for demolition, the Cat 340 UHD features a variety of boom and stick combos. options are available: • e 72-foot, 2-inch front of- fers a maximum 8,160-pound capacity (3.7 tons) at stick pin and maximum horizontal reach of 44 feet, 5 inches at stick nose over the front and side of the machine. • Working with a 7,280-pound maximum weight at stick pin, the 82-foot front off ers a 43- foot, 9-inch maximum reach at stick nose over the front and side of the machine. It matches the Cat MP332 and MP324 multi-processors. ree stick options are available in lengths of 9 feet, 2 inches, 10 feet, 6 inches, and 12 feet, 10 inches. e maximum digging depth for the machine is 24 feet, 3 inches. Hydraulic Quick Connect e UHD's hydraulic boom lines are quickly connected and disconnected by hand and without special tools. Contractors can choose between one- or two-piece boom options for high- productivity truck loading or low-level demolition work. Standard Cat Payload provides on-the-go weighing and real-time estimates of the payload, so operators can achieve precise load targets when working with the one-piece retrofi t boom. e power for this demoli- tion excavator comes from a Cat C9.3 engine rated at 311 horsepower that can run on diesel or B20 biodiesel. ree power modes – power, smart and eco – match the engine and hydraulic output to job needs to lower fuel consump- tion. A new high-effi ciency hydraulic reversing fan cools the engine on demand to also help with fuel effi ciency. Safety Alerts e new 10-inch touch- screen monitor in the 340 UHD displays Cat's active stability monitoring system. is continuously informs operators if the work tool is positioned within the safe working range and provides audible and visual warning alerts when approaching the stability limit.
