III. SPRINGING THE BED
1.
Springing the Bed
A.
Decide which end of the bed will be used as the "take off"
end. Start springing the bed on this end.
**The
“take-off
end
” is where the athletes dismount onto a mat.
B.
Hook two spring ends on the
first
D-ring (the silver rings
that are sewn along the edges of the bed). Take the first
spring in the first D-Ring and attach to the first hole in the
rail. You will then take the second spring in the first
D-Ring and attach it to the second hole in the rail. (See
Fig. 5)
C.
The third spring will attach to the
second
D-ring and hook
to the
third
rail hole.
ALWAYS ATTACH HOOKS DOWNWARDS!!!
(See figure 8 at bottom)
D.
Repeat on the other side. Use the Springing Tool if necessary (See Section 2 for Springing Tool
instructions).
E.
Springing the bed will be much easier and quicker if you have another person hand springing the
opposite side
first
on the Porta Trak while you are using the Springing Tool to spring your side.
When hand springing the opposite side of the Porta Trak, be sure to stay at
least
4-5 springs
ahead of the person using the Springing Tool
.
It will be
necessary to
skip
a
Rail Hole
(not a D-
ring) within the first 15-20 holes to keep the bed wrinkle free.
The
D-Ring
(not rail hole) on the
bed across from the hinge will be
skipped,
to allow the Porta Trak to fold. (
Figure 8
). If you are
setting up the Porta Trak by yourself, hand spring 4-9 springs on one side then alternate to the
other side and continue to use the Springing tool to spring 2-7 springs before you alternate to the
other side again. By continuing down the bed further on the hand sprung side, the amount of
effort to hand spring will remain low. When the bed is attached properly, it should be smooth
and tight.
H.
The last 2-3 springs will attach to the frame at an
angle
. This will keep the bed tight.
I.
After all D-rings have springs attached to them,
double spring
the last d-rings on each side of
the frame. The springs may be difficult to hook, but will provide extra support for the end of the
bed.
For Safety and liability reasons, the Porta Trak’s polypropylene bed should be replaced every 5-6 years
Because of the manufacturer’s variance in the length of Porta Trak beds, your bed may be slightly shorter or longer than
the length of the Workstation frame.
