BOTTIOM DING
Unsupported
Boom-Type
Bottom Loader
Designed to provide flexible long-range operation,
this heavy-duty configuration is both reliable and
easy to use. A minimum of five swivel planes of
rotation offer complete flexibility in making tight
connections for loading and unloading railcars
and tank trucks, and servicing aviation
refuelers. The outboard swivel and
arm adjusts for any changes in
elevation or tilting that may result
as the vehicle is loaded or unloaded.
The unsupported boom-type loader 局
is extremely versatile and many
variations are possible. It can be equipped with
dry-disconnect coupler, union, quick coupling, or
other customer-specified end fitting to make con-
nections on the side, at the rear, or underneath the
vehicle. The intermediate swivel is often inverted
to achieve the low profile and clearances needed
to connect to the underside of a railcar. Typically
installed at or near ground level, arms of varying
lengths can be mounted on staggered risers to
achieve crossover and neat compact storage of
multiple arms in a confined space.
