Caterpillar has unveiled a new hydraulic excavator designed for the demolition industry at the BAUMA trade fair taking place in Munich this week.

The new Cat® 340F UHD (Ultra High Demolition), is designed for high-reach demolition work and has up to 22 metres of vertical pin height. According to Cat it is capable of handling loads up to 3.6 tonnes at a 15 metre horizontal reach has an operating weight of between 44100 to 50400 kg, depending on front and undercarriage configuration.

The company added that a new boom coupling system allows quick configuration of the front to the task at hand and a range of available work tools offers versatility.

Using the boom coupling system, the operator can install and remove high reach or short front components, while a new hydraulic pinning system locks components together.

Cat explained that a short boom nose can be positioned in either a bent or straight position and can be fitted with three available stick lengths.

Quick couplers were said to facilitate rapid work tool changes, and the 340F UHD tool control system stores hydraulic pressures and flows for up to 20 tools, allowing instant adjustment of these parameters for optimum performance.

The 340F UHD C9.3 ACERT™ engine was said to mees EU Stage IV emission standards and has a net power rating of 228 kW (310 PS).

The engine has three power modes – high, standard, and eco – which Cat said assists operators in controlling fuel consumption, and an engine speed controller automatically reduces engine speed in light load situations. In addition, an auto idle shutdown system stops the engine after a preset idling interval.

Comfort & Safety

In high reach applications, the 340F UHD cab can be tilted back to provide the operator an optimal ergonomic position, while an enlarged top window was said to offer 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.

Cat added that for operator comfort and convenience, an automatic climate control system maintains consistent cab temperatures, and heated/cooled seats are available. Joystick controllers and armrests adjust for operator preference, and the LCD monitor is programmable in 42 languages.

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. In addition, a standard rearview camera provides images on the monitor.

LINK technologies such as the Product Link™ system wirelessly connects owners to their equipment. This was said to provide access to valuable machine data such as location, hours, fuel consumption, idle time, events, and diagnostic codes for analysis and reporting via the online VisionLink® user interface.

Maintenance

According to Cat routine maintenance items, such as grease points, fluid taps, filters, and drain tubes, can be reached from ground level, while well positioned handrails, anti-skid surfaces on steps and walkways, and countersunk fasteners enhance safe access onto the machine.

Mesh screens fitted on the 340F UHD side doors were said to reduce the risk  of coolers being clogged with debris, and QuickEvac™ drains for the hydraulic system and engine oil are located in the pump compartment. S·O·SSM fluid sampling ports for the hydraulic, engine oil, and coolant systems allow collecting viable samples from circulating systems, and grouped pressure check ports allow quickly checking system pressures.
