Front Linkage

Made for high stress and long service life

Booms and Sticks

The 312E is offered with a reach boom and three stick congurations: R2.5 m (8'2"), R2.8 m (9'2"), and R3.0 m (9'10").

Also,anew thumb-ready stick with factory brackets and structural reinforcement to attach a Cat hydraulic thumb to the

machine is an available option. Each boom and stick is built with internal bafe plates for added durability, and each undergoes

ultrasound inspection to ensure weld quality and reliability.

Reach conguration 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.
