Caterpillar introduce the new 340F demolition excavator

Cat 340F UHD excavator

Latest high-spec model designed for safe, efficient and high-reach demolition work 

THE new Cat 340F UHD (ultra high demolition) hydraulic excavator has a vertical pin height of up to 22m and is capable of handling loads up to 3.6 tonnes at a 15m horizontal reach. 

Machine operating weight range from 44,100-50,400kg, depending on front and undercarriage configuration, and a new boom coupling system allows the excavator to be quickly configured. A range of available work tools ensures optimum versatility and jobsite efficiency, while the operator environment is designed for optimum safety and comfort.


The 340F UHD main structures, including the upper and lower mainframes, booms, sticks and track-roller frames, have been purpose-built for long-term durability in demolition applications. Undercarriage components (chains, rollers, idlers, and track shoes) are made of high-strength steel and grease-lubricated chains help prolong pin and bushing life, eliminating the intrusion of dirt and debris and reducing travel noise in the process.  

The long undercarriage is available in both fixed gauge (2,590mm) and variable gauge (2,390-2,820mm) configurations. Using the boom coupling system, the operator can easily install and remove high reach or short front components. A short boom nose can be positioned in either a bent or straight position with three optional stick lengths. 

The Stage IV-compliant 340F UHD is powered by a 228kW engine featuring three power modes – high, standard and eco – to assist operators in controlling fuel consumption, while an engine speed controller automatically reduces engine speed in light load situations. For added convenience, an auto idle shutdown system stops the engine after a preset idling interval.

Quick couplers are designed to provide rapid work tool changes, and the 340F UHD tool control system stores hydraulic pressures and flows for up to 20 attachments, allowing instant adjustment of these parameters for optimum performance.

In high-reach applications, the machine cab can be tilted back to give the operator an optimal ergonomic position, while an enlarged top window offers enhanced upward visibility. The demolition type cab incorporates a P5A reinforced windshield and parallel wipers keep large glass areas clean. Front and top falling object guard structures (FOGS) provide added protection.

For operator comfort, an automatic climate control system maintains consistent cab temperatures. Joystick controllers and armrests adjust for operator preference and the LCD monitor is programmable in 42 languages. For operator convenience, an active stability monitoring system continuously informs the driver of work tool position within the safe working envelope and provides a warning when stability limits are approached. 

Routine maintenance items, such as grease points, fluid taps, filters, and drain tubes, are easily accessible from ground level. Well-placed handrails, anti-skid surfaces on steps and walkways, and countersunk fasteners enhance safe access on to the machine.
