Caterpillar expertise in the areas of demolition and recycling has been evident at the DDR Expo 2017 in Brussels. The company displayed two specialized machines, the Cat 340F UHD (Ultra High Demolition) excavator and the Cat MH3024 wheel material handler, as well as a full line of specialized Cat demolition and recycling work tools, including hydraulic hammers, shears, pulverizers, and multi-processors.

In particular, the new Cat 340F UHD hydraulic excavator, designed and manufactured by Caterpillar and distributed through the Cat dealer network, provides 22 meters of vertical pin height and can handle loads of 3.6 tonnes at a 14-meter radius. Operating weights range from 44 100 to 50 400 kg, depending on undercarriage configuration (fixed- or variable-gauge) and front configuration (high-reach or short boom with three stick choices). A new boom-coupling system allows quickly configuring the front to the task.

The 340F UHD uses a 228 kW Cat C9.3 ACERTTM engine that meets EU Stage IV emission standards and provides three power modes to assist operators in controlling fuel consumption. Engine speed automatically reduces in light-load situations, and the engine shuts down after a preset idling interval. Maximum hydraulic-system flow is 570 L/min. at a main-relief pressure of 35 000 kPa. In heavy-lift mode, pressure increases to 38 000 kPa for added power. Maximum drawbar pull is 285 kN for optimum tractive effort and gradeability in all working situations.

The 340F UHD cab can be tilted back to provide the operator an optimal ergonomic position during high-lift operations, and an enlarged top window offers enhanced upward visibility. The demolition-type cab incorporates P5A reinforced windshield and top glass, and parallel wipers keep large glass areas clean. Front and top falling object guard structures (FOGS) provide added protection. Cab features include automatic climate control, heated/cooled seat options, and joystick controllers. The Cat active-stability monitoring system continuously informs the operator of work tool position within the safe working envelope and provides a warning when stability limits are approached.
