INTRODUCTION
Super long reach excavators are designed specifically
for those jobs requiring maximum reach well beyond
the range of normal excavators. Those machines are
designed to drag a small bucket at about 90 degrees
over the side of the tracks towards the excavator; they
are not suited for digging work. Caterpillar offers the
Long Reach excavators for light digging applications
with a much larger digging envelope than normal exca-
vators. Super long reach excavators are suited for ditch
cleaning, slope finishing, river conservation and other
work formerly reserved to draglines.
Caterpillar’s super long reach hydraulic excava-
tors use purpose-built booms and sticks designed by
Caterpillar for maximum performance and durability
in dragging applications.
Super long reach fronts include: boom, stick, linkage
cylinders (boom, stick, and bucket), hydraulic lines and
additional counterweight for stability while working
over the side. Dimensions include bucket.
