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.
1)
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
(→ fig. 3, page 9 for details).

Operation

Each model reel is spring-powered and sel-
fretracting. 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.
