They are designed to significantly increase lift capacity and lower fuel consumption.
Komatsu’s XT-5 closed loop tracked harvesters enable operators to simultaneously travel, cut, delimb, harvest and swing timber. Engineered with hydraulic lines for each function, operators can use tracks, boom, arm and tools concurrently. The benefits of the XT-5 tracked harvesters include significantly greater lift capacity, 10% more power, 16% more torque and 5% lower fuel consumption.
The short-tail swing of Komatsu’s 331 HP harvesters lets operators work through dense forests and clear-cutting environments. The set-back boom allows cutting close to the undercarriage and tracks, while the powerful swing torque excels in demanding applications. Designed to significantly increase lift capacity, handling trees with the arm fully extended is made easier. With good balance between boom lift and arm holding capacity, the XT-5 harvesters can be equipped with a wide selection of harvesting saw heads.
The harvesters can be adapted to the job with two different working ranges. Use the short reach and larger-scaled head to harvest larger trees or switch to a longer reach and more compact designed head to grab trees further from the carrier. Even on steep terrain, operators can work with confidence. The XT455L-5 is equipped with a heavy-duty, four-way leveling system that promotes front/rear/side leveling for exceptional stability. The fuel tank placement lowers the center of gravity for enhanced stability.
The hydraulic tank system design requires 55% less hydraulic oil. Pumps are equipped with hydro-nucleation to help prevent pump cavitation and are 17% larger to help extend component life by operating 500 rpms slower. The engine gull-wing and wide swing-out doors on the XT-5 harvesters offer quick and easy access to all engine service points and all key components. Source
