process ensures every structures are consistently built to high quality. Deep penetration and consistent welds throughout the
frame ensures structures are solidly fused to provide sturdy platform for the linkage and the axles. The bores and the surfaces
are precisely machined for perfect alignments for the pins and precision mating surfaces for major components resulting in
durable frames that allow complete machine rebuild for 2nd or 3rd life.

Z-Bar Loader Linkage

Proven Z-Bar loader linkage geometry generates powerful breakout force and an increased rack back angle for better bucket
loading and material retention. Heavy duty steel lift arms with cast steel cross tube ensures extreme loads encountered during
loading and tramming are efficiently dissipated for long service life.

Sealed Pins
Sealed colleted pins are fitted to all bucket and lift arm hinge points for longer pin and bushing life. This reduces maintenance
costs and extends service intervals. The sealed joints retain lubrication and prevent contaminant entry.

Hitch
Spread hitch design widens the distance between upper and lower hitch plates to distribute forces and increase bearing life.
Thicker hitch plates reduce deflection. The wide opening provides easy service access. Upper and lower hitch pins pivot on roller
bearings to distribute horizontal and vertical loads over a greater surface area. Shim adjusted preload reduces maintenance
time. An on-board steering frame lock pin is fitted to prevent articulation during maintenance and service.

Gradeability/Speed/Rimpull
To determine gradeability performance: Read from gross weight down to the percent of total resistance. Total resistance equals
actual percent grade plus rolling resistance. As a general guide use 2% for rolling resistance in underground application or refer to the
Caterpillar Performance Handbook. From the total resistance point, read horizontally to the curve with the highest obtainable gear,
then down to maximum speed. Usable rimpull will depend upon traction available and weight on drive wheels.
