Milton CAT 990H - Manual (Page 7)

Structure Construction. Is more
than 80 percent robotically welded.
This provides highly consistent welds
with deep plate penetration and excellent
plate fusion. The benefit is greater fatigue
strength and longer life than with
conventional welding methods.
1 Box Section Rear Frame. Absorbs
torsional forces generated in a loading
cycle, maintaining alignment for hitch
pins and driveline.
2 Four-Plate Loader Tower. Resists shock
and torsional loads maintaining hitch
and loader linkage pin alignment.
3 Design. Is for optimum strength.
The 990H is equipped with a single-tilt
Z-bar loader linkage with cast cross tube,
cast tilt lever, solid plate lift arms,
serviceable grease B-pin and center-
point frame articulation. 4 Computer-Controlled Machining.
At the top level allows structures to remain
in their fixture throughout the machining
process to ensure pin bore, axle pad and
engine/transmission alignments.
Optional High Lift Linkage Configuration.
Is available as a standard attachment.
The High Lift configuration offers
565 mm (22.3 in) more dump clearance
and 293 mm (11.5 in) additional reach
at full lift and 45° dump. This gives the
ability to load the 777 in six passes.
