When your facility is short on space, there may be
a better solution than rebuilding or remodeling.
Shaw-Box® top-running double girder trolleys are
designed to make the most of a tight space. These
compact, low profile crane trolleys provide a
combination of lower headroom, higher hook lift
and closer end approaches.
Shaw-Box® top-running trolleys maximize your
building area by
providing
maximum
wallto-wall,
floor-to-hook
coverage with minimum
required clearance between roof trusses and
building columns.
Shaw-Box® top running trolleys deliver
exceptional performance. Rugged, heavy duty
frames and precision-cut heat treated gearing
provide superior wear-life with a minimum of
maintenance. Motors specially designed to
withstand the rigors of crane duty provide smooth
acceleration and pinpoint spotting. No other toprunning
trolleys combine the same high
performance, quality and value. Feature for
feature, Shaw-Box® trolleys come out on top.
Shaw-Box® DMR trolleys are ideal where low profile,
higher capacities, and faster speeds, are required.
Rated from 7-1/2 to 60 tons, DMR trolleys feature
welded steel one-piece frames, totally enclosed crane
duty motors, independent hoist motor and load brakes
and efficient oil bath-lubricated drive trains for
precision control with a minimum of maintenance.
