Mainframe Strength. The D8T mainframe
is built to absorb high impact shock
loads and twisting forces.
Frame Rails. Full box section, designed
to keep components rigidly aligned.
Heavy Steel Castings. Adds strength
to the main case, equalizer bar saddle,
front cross member and tag-link trunnion.
Top and Bottom Rails. Continuous rolled
sections, with no machining or welding,
to provide superior mainframe durability.
Main Case. Elevates the final drives
well above the ground level work area
to protect them from impact loads,
abrasion and contaminants.
Pivot Shaft. The D8T pivot shaft runs
through the mainframe and connects to
the roller frames, allowing independent
oscillation. The full-length pivot shaft
distributes impact loads throughout
the case, reducing the bending stress
on the case.
Equalizer Bar. The equalizer bar features
limited slip seals and an oil-lubricated
joint for better oil flow. Large forged
pads reduce wear on the mainframe
and extend sealed joint life.
Tag-Link. The Tag-Link brings the blade
closer to the machine for more precise
dozing and load control.
The Tag-Link design provides solid
lateral stability and better cylinder
positions for constant break out force,
independent of blade height.
