5.3 AM-SE - STRADDLE EXTENSION KIT –
SET-UP AND OPERATION
Straddle Extension - Components
The AM-SE Straddle Extension kit can be set up by one
person without tools. The AM-SE kit consists of eight (8)
structural components. Those eight (8) components are:
1. Two (2) extendable side lifting rails.
2. Two (2) end straddle supports on locking swivel
caster wheels, each with (hand cranked) lifting winch
and winch cables, outrigger interlock - retractable
cable reel and quick-release safety pins.
3. Four (4) short outrigger (pup) beams which intercon-
nect the straddle extension side lifting rails with the
AM/EL base outrigger sockets.
Mounting - Straddle Ext. to AM/EL Machine
(See Figure 5-3.)
1. Near work area find a suitable area large enough to
assemble the AM/EL machine to the Straddle Exten-
sion Kit. Assembly area should be a smooth, firm,
level surface on which the assembled straddle
extension and AM/EL machine can be easily
maneuvered.
2. Locate both extendable side lifting rails and the four
(4) (pup) outrigger beams.
3. Start with either side and install one (1) of the (pup)
outrigger beams into an outrigger socket in the AM/
EL base. Push it in until the locking pin secures the
(pup) beam in place.
4. Next pick-up one (1) of the side lifting rails (position
with the outrigger sockets on the bottom), align the
(pup) outrigger beam installed in previous step with
the appropriate side lifting rail outrigger socket and
slide the side lifting rail onto the (pup) outrigger
beam.
5. On the same side lifting rail install the remaining
(pup) outrigger beam into the side lifting rail socket
and align with the AM/EL base outrigger socket.
Push (pup) beam in until the locking pin in the AM/
EL base secures the (pup) beam in place.
6. Mount the remaining side lifting rail by repeating the
instructions in steps 4 and 5.
7. Next locate either end straddle support, (mount end
straddle support with the winch handle positioned to
outside), align the two vertical rails of the end strad-
dle support with the adjust bracket opening on ends
of lifting rails.
NOTE: Lock the castor wheels on the bottom of the end
straddle supports so they are parallel with the outrig-
ger sockets. This will help to keep the end straddle
support stable during assembly.
8. Insert vertical rails into the adjust brackets (in
against the slide pads), and insert an adjust bracket
end cap (with slide pad against vertical rail) into the
slot on the adjust brackets on both side rails.
9. Secure end caps with the quick-release pin wired to
the end cap, install pin into hole in adjust bracket
just above end cap. (See Figure 5-3. and 5-4.)
10. Repeat steps seven, eight and nine to mount other
end straddle support.
11. At both end straddle supports, attach the winch
cable clevis ends to the lifting lugs (on the side lifting
rail - adjust brackets), using the quick-release pins
attached to winch cables.
12. Turn winch handle clockwise just enough to start lift-
ing side rails. Observe winch cables, both cables
must be lifting evenly.
If not lifting evenly, adjust slack out of long cable
using the following steps:
a. Lower side rails by turning winch handles
counter-clockwise enough to remove any ten-
sion on the winch cables.
b. Remove the quick-release pin securing the
winch cable clevis to the lifting lug on the side
rail adjust bracket.
c. Loosen the jam nut on the threaded cable end
and turn the clevis end clockwise to shorten the
cable.
d. Before tightening the jam nut re-install the winch
cable to the side rail lifting lug with the quick
release pin.
e. Turn winch handle to start lifting side rails, again
observe winch cables. If cables are lifting evenly,
retighten jam nut on threaded end of winch
cable. If not lifting evenly repeat steps (a)
through (e) until properly adjusted.
13. Connect the outrigger interlock cable ends (male)
from the retractable reels (mounted on both end
straddle supports) to the connector ends (female)
mounted on the AM/EL base frame under the plat-
form.
