Booms and Sticks
The 349E is offered with a range of booms and sticks.
Each is built with internal baffle plates and stress­relieved for
added durability, and each undergoes ultrasound inspection
to ensure quality and reliability. Large box­section structures
with thick, multi­plate fabrications, castings, and forgings are
used in high­stress areas such as the boom nose, boom foot,
boom cylinder, and stick foot to improve durability. Also, the
boom nose pin retention method is a captured flag design for
enhanced durability.
Selections
Two boom types are offered:
HD = Heavy Duty Reach. HD is designed for general
excavator applications such as multipurpose digging and
loading, and it includes additional steel to make it more
durable and better suited for more demanding applications
like moving rock or using a hammer.
ME = Mass Excavation. ME is best used for quarry, high­
volume loading, and other demanding applications. The ME
front provides higher digging forces due to the geometry of
the boom and stick relationship. Bucket linkage and cylinders
are also built for greater durability.
