Assemble 10-Mile Hoseline Segment.
(1) Assembly of the 10-mile hoseline segment requires the equipment and personnel outlined in paragraph 2-8.a.
These requirements generally remain the same in each situation. However, the number of components
required for assembly will vary depending on the route and terrain being crossed, as well as the assigned
mission.
(2) Hoseline is packed in crates marked HOSE ASSEMBLY, 6 INCH, 500 FEET.
(3) One 6-inch boltless coupling is required for each 500 ft (152.5 m) hoseline assembly used. One swivel joint is
required for every 1000 ft (305 m) of hoseline.
(4) Road crossing guards and suspension kits are used when the hoseline crosses roads or obstacles in the terrain
(such as streams, rivers, gullies, and ravines). Each road crossing guard is 5 ft (1.5 m) in length. If the width
of a road being crossed is 15 ft (4.58 m), for example, then three or four road crossing guards are required to
protect the hoseline. Each suspension kit contains enough wire rope to construct a span of 200 ft (61 m).
Therefore, one suspension kit is required to cross a 150 ft (45.75 m) wide ravine; or one suspension kit can be
used to construct spans across two 75 ft (22.88 m) wide gullies.
(5) The pressure-reducing valve is needed when pressure at a certain point in the hoseline is expected to exceed
225 psi (1551.15 kPa). If the hoseline crosses over a steep hill or ridge, then a pressurereducing valve may be
required on the "downhill" side of the hoseline route.
(6) Other components contained in the 10-MILE SEGMENT crate are used for various purposes. The end cap is
used when dead-end service is required (end of hoseline route does not connect to a storage and/or distribution
assembly). The repair kit is used to repair damaged hoseline. The displacement and evacuation kit is used to
recover and pack hoseline.
(7) Contact unit maintenance and load tricons on trucks as follows:
WARNING
Make sure crane or forklift has minimum lifting capacity of 6000 lb (2724
kg). DO NOT stand under load being lifted. Death or serious injury may
result.
(a) Using crane or forklift with 6000 lb (2724 kg) lifting capacity, lift and stack tricons with hoselines on truck
bed.
(b) If truck does not have sidewalls, use lifting devises as attachment points and securely tie tricons to truck.
(c) Refer to applicable technical manual for preparing tricons for hose-laying operations.
(8) Lay out and install hoses as follows:
CAUTION
After removing components from boxes, be sure to protect them from
sand and grit. Sand and grit may cause equipment failure.
