The TB260, in action this week at ICUEE 2013, will replace the five-ton, TB250 model in the company lineup, a move that reflects the preferences of more and more contractors who say they want a bigger machine in this range, says David Caldwell, product and training manager.
A 47-horsepower Yannmar Diesel engine powers the unit. Variable displacement pumps speed up cycle times and help generate 12,756 pounds of breakout force at the bucket.
With the new engine, Takeuchi ditched the tilt up cab design of the TB250 and put one access hood/cowling below cab-level on the operators right and one at the rear of the machine. The new engine features a turbocharger and diesel particulate filter/diesel oxidation catalyst. But unlike some Tier 4 changeovers which take up extra space in the engine compartment, Takeuchi was able to fit this engine into a smaller space than the TB250, Caldwell says.
Fuel consumption is reduced by an auto-idle function and an eco-mode default setting, which together can cut diesel use by as much as 21 percent.
Pilot joysticks deliver, smooth proportional control of the boom and implements. Primary and secondary auxiliary hydraulics are plumbed onto the machine as standard and are activated with finger-tip controls on the joysticks.
The TB260’s dozer blade comes with a blade-float feature. You can also order an optional power-angle-tilt blade with a reversible/replaceable cutting edge.
An in-cab LCD color monitor enables operators to select dozens of different preconfigured work modes and tools and can be customized for specific attachments.
