Axle Conduit
13. Verify that the pipe is level and secure the band clamp
to the underside of the second rafter using an FA4484
Tek screw. Pipe should remain loose in the band clamp.
Band clamps support the axle conduit at each rafter
except the end rafter where the gearbox is mounted.
14. Take a section of 131S075 pipe, attach it to the first,
and secure the connection using one Tek screw.
15. Slide another band clamp onto the tapered/swaged end
of the conduit, level the conduit, and secure the band
clamp to the underside of the next rafter.
16. Continue adding conduit and band clamps and work
toward the other end of the shelter. Verify that the axle
conduit remains level throughout the length.
Attach one
band clamp to the inside of each rafter.
17. Select the final section of plain pipe (131P0XX where
XX represents the length needed to reach the end of
your building. Consult side profile diagram for pipe
identification.)
NOTE:
Do not allow the free end of the axle to touch
the inside surface of the end wall. Trim pipe if needed.
Axle must turn freely.
18. After installing all sections of axle conduit for the first
drop-down curtain assembly, verify that the axle conduit
is level and that each conduit splice is secured with a
Tek screw (Step 14).
19. Move to the gearbox and test the assembly using the
crank handle.
NOTE:
The assembled axle conduit should turn freely
throughout the length of the shelter. Adjust the band
clamps as needed. Reposition clamps and screws if
these prevent smooth operation of the axle conduit.
20. After verifying that the axle turns smoothly, repeat the
procedure to assemble and attach the gearbox and
axle conduit
to the other side of the shelter.
21. Continue by preparing and attaching the drop-down
curtains to the frame and axle conduit of both drop-
down assemblies.
