BTB 41: TIGERCAT POWERED 822D
Published on: Sunday 1st November 2015
For areas of improvement, the designers aimed at service access, the operating environment, improved hydraulic efficiency and increased hydraulic component commonality with other 800 series machines. The all-new upper structure houses a Tigercat FPT engine available with a Tier 4f clean diesel emission control system. A higher capacity cooling system improves performance in hot climate regions. The redesigned engine enclosure profile further improves all-important right hand side visibility.
The entire engine compartment is exposed with the independent power operated side platform and roof enclosures. Access to components and daily service points is excellent with ground level fueling and easy access to the hydraulic filters, hydraulic oil fill pumps, swing gearbox remote oil level tank, DEF injection pump, DEF tank, cooling system components and both sides of the engine. The redesign has also allowed for a larger standard fuel tank, increasing capacity to 585 L (155 US gal).
A new cab structure with narrower front posts and larger side windows further enhances visibility, with improved sight lines to both the right and left sides of the cab. The skylight has been replaced by a camera system providing the operator with a much wider field of view, and eliminating visibility inhibiting elements like snow and debris for year round capability.
The 822D is standard equipped with LED lighting for improved productivity in night shift operations and improved reliability.
The cab interior is quieter and instrumentation has been thoughtfully placed to optimize ergonomics. The electronic control system interface screen includes a seven inch (180 mm) touch screen colour monitor and there are multiple mounting points for additional electronic devices. Clever door hinge geometry allows the front door to swing level for easier opening and closing.
With tight tuck boom geometry and near zero tail swing, the 822D is a powerful, yet compact machine well suited to selective felling and clear fell applications.
