OSR45 - CONNECTING THE OSR45 TO A
SPREADER
To pick up the overheight frame from the storage
fixture the spreader needs to land on the overheight
frame and then do the twistlock ‘lock’ plus ‘unlock’
motion.
During this twistlock movement, a cam wheel in
the storage fixture will rotate to release a mecha-
nism which has been holding up a push rod in the
overheight frame. The push rod is connected with
a spring mechanism, which will push it downwards,
and as a result pull up the latches to engage on the
spreader lugs.
When the push rod comes into a down position, a
plunger will protrude into a hole in the frame, ensur-
ing the latch will stay in its hooked-on position.
The push rod gets an extra movement downward
through a connected spring mechanism, and will be
kept in position.
As the twistlocks will now be unlocked, and the
latches engaged on the spreader lugs, the overheight
frame can be lifted from the storage fixture. The
overheight frame will now only be hanging through
the latches holding on to the spreader lugs.
Once the overheight frame is lifted up from the
storage fixture, a spring mechanism will push up
the release mechanism in the storage fixture, for it
to function accordingly when the overheight frame
needs to be disconnected from the spreader.
