Description
Mounting
High-capacity reel models 7340 and 7341 are
designed for severe environments, such as a lubrication
truck. They can also mount to a ceiling* or wall.
NOTE: The Hose Guide Arms can attach
to the Base Assembly in five (5) different
positions.
These reels mount as a single unit or in banks of as
many as required. See Figure 4 for details.
Operation
Each model reel is spring-powered and self-
retracting. When the hose is extended, the reel can be
latched on either of two ratchet sections per revolution
of the sheave. A pull releases the latch from the ratchet
and allows the hose to retract onto the reel.
Reel Models 7340 and 7341
Reel model 7340 contains a high-pressure swivel
assembly. The reel is designed to dispense grease
through a 3/8 " ID two-wire braid delivery hose.
A medium-pressure swivel assembly is included
with model 7341. This reel is designed for 1/2 " ID
hose to dispense fluid lubricants (such as motor and
gear oil and automatic transmission fluid) and air.
Delivery Hose
Each model reel manages a maximum length of
delivery hose as indicated in Table 1.
