Front Linkage Options. The Reach Boom
allows excellent all-around versatility
and a large working envelope. It can
be equipped with the following
three sticks:
• R2.9B1 – performs well in a mid-
range working envelope
• R2.5B1 – a good match when the job
requires a larger bucket or a hammer
Boom. The boom has a large cross-section
and internal baffle plates to provide long
life durability.
Sticks. The sticks are made of high tensile
strength steel using a large box section
design with interior baffle plates.
Heavy-Duty Reach Boom. Provides
additional strength recommended for
tough applications.
Bucket Linkage. The power link improves
durability, increases machine-lifting
capability in key positions and is easier
to use than compared to the previous
power link. Lifting from the power link
lift eye gives you the optimum lift
performance. It allows you to lower
the load point, which maximizes the
use of the boom cylinders.
