Rugged main frame design
maximizes durability.
• Outer frame utilizes curved side
rails, which are di-formed for
excellent uniformity and strength.
• Box-section channels improve upper
frame rigidity under the cab.
• Inverted U-channels span the width
of the main frame and are formed,
rather than fabricated, for superior
strength and reduced weight.
• Boom tower and main rails are
constructed of solid, high-tensile
strength, steel plates.
• Boom foot and engine mount areas
are reinforced for additional strength.
• Sheet metal supporting structure is
improved by integrating the mounting
into the upper frame structure.
Carbody Design. Advanced, reinforced,
purpose-built carbody design stands up
in the toughest forest applications.
Carbody Structure. Wide, tall, and thick
carbody structure provides operating
stability and durability while improving
operation’s effectiveness.
• Upper structure weight and stresses
are distributed evenly across the full
length of the track roller frame.
• Smooth transitions and long welds
help reduce stresses at the carbody-
to-roller frame junctions for
excellent durability.
• Robot welding helps ensure consistent,
high-quality welds throughout the
manufacturing process.
