Designed to provide flexible long range operation
without the use of hose, 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
rail cars 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
bottom loader 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 connections on the side,
athe 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 rail car.
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. Available in 2", 3", 4", and 6"
sizes in steel, stainless steel, aluminium, and specialty
alloys and choice of flanged, threaded, or all welded
construction.
Counterweighted
Hose Loader
Installation
and operation is simple and efficient with OPW counterweighted
hose loaders. Adjustable counterweights mounted on a
pair of horizontal rails are simply moved until the
desired balance point is located. This design provides
for efficient handling and coupling to the tank truck
adaptor.
Available in 4" and 6" X 4" sizes, this
popular hose loader features a flange x flange base
joint for reliable performance and ease of maintenance.
A heavy-duty split flange base swivel (pg. 17) is standard
on 4" arms. Construction is carbon steel with composite
drop hose for maximum flexibility and easy handling.
Braided stainless steel hose is also available. Outboard
swivel, spacer spool, and API coupler are aluminum.
Standard
horizontal reach is 114" to fully cover the API
RP-1004 bottom loading envelope with up to four loading
arms spaced 18" apart. Reaches of 66", 78",
90" and 102" are also available, but full
coverage of the API envelope may require moving the
truck. Each loader should be mounted successively higher,
16" stagger recommended, to provide maximum crossover
capability for efficient simultaneous compartment loading.
Minimum recommended drop hose length is approximately
60".
