Milton CAT 316E - Manual (Page 7)

Front Linkage
Made for high stress and long service life
Booms and Sticks
The 316E is offered with a reach boom and three stick
configurations: R3.1 m (10'2"), R2.9 m (9'6"), and R2.6 m
(8'6"). Also, a new thumb-ready stick with brackets to attach
a Cat thumb on the machine is an available option. Each boom
and stick is built with internal baffle plates for added durability,
and each undergoes ultrasound inspection to ensure weld
quality and reliability.
Reach configuration balances digging force and bucket
capacity. It covers all applications this size of machine was
designed to take on such as digging, loading, trenching,
and working with hydraulic tools.
Large box-section structures with thick, multi-plate
fabrications, castings, and forgings are used in high-stress
areas such as the boom nose, boom foot, boom cylinder,
and stick foot to improve durability. Also, the front linkage
pins’ inner bearing surfaces are welded with a self-lubricated
bearing used to extend service intervals and increase uptime.
