Tigercat positions new H855C against excavator based processor carriers
PARIS ON, SEPTEMBER 26, 2007 – The H855C is a purpose built
carrier designed specifically for harvesting, in-woods processing and roadside
processing applications. Based on Tigercat's flagship 860C series carriers, the
H855C uses the same upper frame structure, cab and boom systems as the H860C.
The engine and hydraulic system are specifically designed to achieve maximum
performance and minimum fuel consumption in harvesting and processing
applications. Essentially, the H855C is a machine perfectly matched to the vast
majority of the world's harvesting and processing applications at a purchase
price that is competitive with much less capable excavator conversions.
The H855C is powered by a 6.4 L turbocharged and aftercooled Tier III
Mercedes 906, delivering 205 kW (275 hp) at 2,200 rpm. The same engine is used in
the Tigercat forwarder line and the new 845C feller buncher. High horsepower
allows the H855C to maintain hydraulic flow as the pressure increases, keeping
roll speed up and significantly boosting productivity.
Because the H855C hydraulic system is designed specifically to
power harvesting attachments, it is far more efficient and productive than
modified excavators. "A dedicated attachment pump supplies oil to
the primary head functions, delivering flow and pressure to match the
demands of the head without interference from other machine functions. Under
high flow conditions like roll or saw operation, additional oil is supplied from
the main load sensing system," explains Grant Somerville, advanced
engineering manager, track machines. "The
result is a hydraulic system that provides high head performance and
multi-functioning capabilities while still delivering excellent fuel economy."
Field reports indicate that H855C fuel usage can be as low as 15
L/hr (4 US gph) and recent independent studies have shown that Tigercat purpose built track
harvesters are 20-25% more productive than similarly sized excavator conversions
equipped with the same attachment.
Another big advantage of the H855C is the high capacity cooling
system. The
reversible fan is hydraulically driven and computer controlled to match cooling
requirements. This improves fuel efficiency and makes cold weather starts
easier. The variable speed fan helps keep hydraulic oil temperatures more even
in cold weather conditions for improved measuring system performance and
accuracy.
