INTRODUCTION
Long reach excavators are designed purposely for
light duty digging that requires reach capability well
above that of normal digging machines. To be able to
have high enough digging forces together with an
acceptable size bucket, the long reach excavators have a
smaller digging envelope than the ditch cleaning
machines. Long reach excavators are ideally suited for
deep digging in gravel or sand pits then feeding directly
into a hopper.
Caterpillar’s long reach hydraulic excavators use
purpose-built booms and sticks designed by Caterpillar
for maximum performance and durability in light duty
applications.
Long Reach Excavation Fronts include: boom, stick,
linkage cylinders (boom, stick, and bucket), hydraulic
lines, additional counterweight for stability over the
side and heavy duty wide undercarriage. Dimensions
include light excavation bucket.
