ARM, SWIVEL, SINGLE PROBE RECEIVER

DESCRIPTION
The Single Probe Receiver Swivel Arm is a welded
high-strength steel assembly. It consists primarily of
a main body or arm to which other components are
attached. Attached to one end of the main arm are
two side plates that provide the means of attaching
the assembly to the Probe Receiver using throughbolts.
The side plates provide the support for a
pelican hook that is also through-bolted to the
plates. A pin is permanently installed between the
side plates and provides a positive stop to limit the
open position of the pelican hook. A bale, or latch,
for the pelican hook is through-bolted to the main
arm. The pelican hook can be locked in the closed
position by closing the bail over the end of the hook
and inserting a 3/16-inch diameter by 3-inch long
steel cotter pin through a hole in the free end of the
pelican hook. The main arm is lightened by four
holes. A hole, with bronze bushing, penetrates the
other end of the arm and provides the means of
connecting the assembly to the Probe Swivel joint
again using a through-bolt. This
through-bolt is the pivot point for vertical swing of
the assembly.
FUNCTION
The Single Probe Receiver Swivel Arm is required
to provide the means of attaching the Probe
Receiver to the Probe Swivel joint. The pelican
hook of the assembly provides a quick-release
means of attaching the end of the spanwire to the
