880 Logger Starts Strong
Published on: Monday 21st November 2011
BRANTFORD ON, NOVEMBER 21, 2011 – In Late August Tigercat shipped its prototype 880 logger to our British Columbia distributor, Parker Pacific. The machine was delivered to Parker’s Prince George branch where staff hosted a three day open house for customers to view and test drive the 880. Customer feedback was very positive.
Tigercat undertook the 880 project to offer the marketplace a purpose-built forestry carrier that solves many of the problems experienced by owners of converted excavators. The project involved a wide range of participants from Tigercat and Parker Pacific as well as loader and shovel logger owners and operators. Throughout the design process, review meetings were held with these groups to ensure design work was meeting everyone’s expectations. Advanced engineering manager, Grant Somerville explains that while this more process lengthened the design stage, “The end result was a machine that met the requirements with few surprises.”
The prototype 880 was purchased by Blue Valley Enterprises Ltd. during the design phase of the project. “Their confidence in our abilities and patience throughout the entire project was greatly appreciated by all of us at Tigercat,” adds Somerville. BVE is presently operating the machine near Vanderhoof, BC and early field results have been extremely positive. From an operating standpoint the 880 is viewed as a very stable carrier with excellent lift capacity at extended reach that performs well beyond its size classification. Operators also commented on the quiet operating environment and excellent visibility.
The 224 kW (300 hp) 880 logger can be equipped for shovel logging, loading or processing with a live heel, power clam, butt-n-top or processing attachment. The 300 horsepower engine significantly increases machine productivity and travel speed relative to excavator conversions while delivering excellent fuel efficiency.
One of the innovative design features of the new 880 is the closed loop swing drive system. This system eliminates energy loss from swing relief valves during swing acceleration and recovers energy stored in the swinging boom and upper frame assembly during braking. The dedicated swing drive system also reserves all main hydraulic pump flow for boom and attachment functions, increasing speed and productivity. Another energy saving feature is the hydraulically driven and computer controlled variable speed, reversing cooling fan. Air intakes and outlets are large for optimal cooling airflow.
Tigercat designed a new undercarriage called the F7-163 with 334 kN (75,000 lbf) tractive effort and an overall width of 3 630 mm (143 in) with standard track pads. The super duty FH400 track components were taken directly from the 870C series bunchers.
The cab forward design combined with the main boom curvature provides excellent visibility throughout the operator’s working sight line. The expansive, comfortable, ergonomic cab interior is designed to minimize operator strain and fatigue during long shifts.
One of the design criteria for the 880 was to create a machine with better service access and component layout than any competing machine available on the market today. The results speak for themselves. The 880 is equipped with independent power operated side door and roof top openings, exposing the entire engine compartment for direct and convenient access to the engine, hydraulic pumps, valves and cooling system. All daily service points can be accessed through the side door, eliminating the requirement to open the entire roof enclosure on a daily basis. The layout also separates the hydraulic system components from hot engine parts.
Tigercat Industries designs and manufactures premium quality forestry and off-road equipment with manufacturing facilities in Canada and worldwide distribution. The diverse product range includes complete full-tree and cut-to-length harvesting systems, a growing line of land clearing and vegetation management equipment and specialized off-road industrial and material handling machinery.
