The new Tier IV final specification of the Yanmar 4TNV98CT diesel engine provides 51.6.kW Gross power for potentially a ten percent productivity improvement. Owners of the TB280FR are able to optimise fuel consumption with the excavator’s auto engine idle system. Other potential fuel savings can be made by selecting from a menu of work modes.
There is an enhanced cooling system, complemented by a new counterweight profile which is designed to substantially increase the flow of air to the engine.
A comprehensive multi-function colour display monitor puts the operator in complete control by providing a clear and instant view of all vital systems such as particulate matter accumulation and the lift/load percentage on the craning safety system.
The auxiliary output flow has not only been substantially increased, but is selectable between 148 l/m and 58 l/m, providing a better match for certain types of accessory tools. A factory fitted twin pump flow (Hyflow) is now standard – a feature that will appeal to drilling contractors who appreciate the excavator’s capability to drill very close to its track frames.
The TB280FR has a standard operating mass of 8,653 kg, putting the excavator in the CCF 7.5 class (7.5 to 10 tonnes), however the machine’s operating mass when rigged with a hydraulic hitch and GP bucket will be closer to 9 tonnes. If fitted with optional steel tracks with rubber pads, this will add additional mass of 205 kg.
The ‘float’ function blade is of more robust construction and has longer arms, increasing OAL by around 100 mm. What was previously the medium length stick is now standard equipment, giving a maximum digging depth of 4,885 mm (including the hydraulic hitch).
The new TB280FR retains its unique Full Zero Turn capability, thanks to its patented side shifting boom system and enables the machine to work effectively between two walls, excavating at the front and being able to load a truck placed behind the excavator.
A major advance is a cabin that features integral ROPS & FOPS level II protection, with the addition of a retractable sun shade.
The TB280FR also retains Takeuchi’s signature self-adjusting track tensioning system, triple flanged track rollers, two way control pattern selector, pilot system accumulator, auto downshift drive motors and numerous other Takeuchi innovations like cushioned boom and arm and offset cylinders for smoother operations.
