Milton CAT D6T - Manual (Page 10)

Frame and Castings. The D6T frame is
built to absorb high impact shock loads
and twisting forces. The frame has a
reinforced saddle and a welded front
cross-member that add strength to
the frame to better handle lateral and
twisting forces. Steel castings augment
the strength of the main case.
VPAT Frame. The D6T VPAT frame
has solid side rails to provide a stronger
structure. The trunnion joint is located in
the saddle to allow the dozer side loads to
go into the mainframe instead of through
the radiator guard. The reinforced
saddle accommodates additional loads
through the frame.
Pivot Shaft. The pivot shaft is bolted
to the mainframe and connects to the
rear roller frames to allow independent
oscillation. The pivot shaft distributes
impact loads through the case.
This design eliminates alignment
problems and the need for diagonal
braces on the roller frames. Equalizer Bar. The pinned equalizer bar
gives the roller frames the ability to
oscillate up or down independently
to better match ground contours while
providing maximum traction and operator
comfort. The redesigned equalizer bar
features bolted end pins to offer longer
life and reduce downtime. This design
also allows for improved serviceability
and reliability.
