Compared
to hydraulic hammers, cutter head attachments and cutter-bucket
combinations have a more narrow trench with smaller footprint
which requires
less
fill.
Trenching
with
cutter head attachments and cutter-bucket combinations creates
smooth, safe walls, and has lower vibrations. It makes much less
noise
which
makes
for
better
operation
in sensitive
areas. The cut material is suitable for backfill and pipe bedding
which means about 50% less backfill is required, creating significate
concrete savings. Lastly, trenching with a cutter head attachment
or a cutter-bucket combination gives the contractor a higher
rate
of production for
most material. |
