 Section 2. HOSE REEL TRAILER
4.2.1 POWER-ASSIST LOADING. Navy shore establishments that support large
numbers of active Navy vessels will find sewage hose deployment and retrieval
techniques greatly enhanced by using a hose reel trailer. The following
steps discuss power-assist procedures which may be followed for both col-
lapsible and noncollapsible sewage hoses, stored in straight lines or in
coils.
a. Loading/Sewage Hoses Stored in Straight Lines. The procedure for
loading the hose reel trailer is identical for both collapsible and noncol-
lapsible sewage hoses stored in straight lines. In addition, the steps for
loading are similar whether the hoses are stored on a rack or on the ground.
A trailer mounted, pneumatic powered hose reel, described under purchase
description 4630-1562B-79-2 of 11 June 1979, is under central procurement by
NAVFACENGCOM. This hose reel trailer permits power-assist loadings of sewage
hoses stored in straight lines. The loaded trailer then is transported to
the pier site by a truck equipped with 2 5/16-inch ball hitch. At the pier
the hose is payed out and lifted aboard ship. Power for the hose reel is
supplied by a gasoline-driven air compressor which powers an air motor.
The motor engages a gear reduction mechanism which rotates the hose reel at
5 rpm. The reel has a 500-foot storage capacity that accommodates 4-inch
sewage hoses. Alternative air supply pressure, from either pier supply or
portable compressor, must have a minimum rating of 50 pounds per square inch
for quantities of over 50 standard cubic feet per minute. See Figure 4-1.
(1) Loading the Reel from Shelves. When the hoses are stored on
shelves, they are removed and laid in straight lines on the pavement
adjacent to the storage unit with the male fittings facing in one
direction. The transport vehicle is brought as close as possible to the
male ends "of the hoses. The first hose is pulled to the vehicle and
connected to a hose cap which is attached to the reel. The reel is rotated
under power to pull the length of hose aboard. One member of the two-man
shore crew operates the reel, while the other guides the hose onto the reel.
The first 50-foot length of hose is guided onto the reel until its
female fitting is positioned in line with the male fitting of the next
length of hose to be loaded. Then the reel is stopped, the couplings are
joined, and the reel is started again so the second length can be loaded.
The steps are repeated until the reel reaches its capacity.
(2) Loading the Reel from the Ground. If the hose is stored in
straight lines on the ground, the procedure is the same as above, except
that the hoses do not need to be removed from storage shelves.
b. Sewage Hoses Stored in Coils. The procedures for transporting
hoses when no hose reel trailer is available are listed below.
(1) Collapsible Rubber Hoses. For power-assist loading of col-
lapsible rubber hose coils, the hoses must be stored on pallets. Two
50-foot coils of collapsible rubber hose are stored on each pallet. The
following steps should be taken for mechanized loading of coiled rubber
hoses aboard the transport vehicle. See Figure 4-2.
