CEILING CLOSURE HINGE INSTALLATION
Figure 8a. Figure 8b. Figure 8c.
Mounting the Hinge and the ceiling closure to the ceiling:
The hinge should be mounted to the
underside of the ceiling, 10” back from the
boom pivot point. See figure 9 for an
elevation view. The proper installed height
of the lift should be 2” from the bottom of
the boom to the inside of the framework and
ceiling closure. This allows the closure-
lifting arm to be adjusted for proper closure.
The hinge mounting position should be set to
allow a snug fit at the back of the ceiling
closure, but not so tight as to bend or pull the
ceiling closure when closing. Care must be
taken when mounting the hinge onto a solid
support. The lift will exert a forward pull on
the closure when closing since it is not
directly connected to the lift. Use all holes
on the hinge with bolts that cannot be
loosened.
Figure 9
Step 3: After the hinge is attached, connect the two pull-up arms (already attached to the boom) to the
ceiling closure with four (4) 4/20" x 1" flathead bolts and nuts. The Two (2) 3/8" pivoting bolts should
be loose enough to pivot easily when the lift is in motion.
1. The closure and pull up arms are adjusted by loosening the four bolts and nuts on the slotted part of the
pull up arms just enough to slide when the closure contacts with the ceiling. (A lip or beveled edge is
suggested around the opening.)
2. Slowly close the lift to allow the slider to adjust to the proper height when the up closure hits the lip and
stops. The boom will continue to raise until it reaches the the limit switches , which will shut the motor
off.
3. Next, lower the lift until a 1" gap is showing from the ceiling and check the left and right sides to level
the closure. If a correction is needed then readjust the pull-up arm(s) to correct the height/level (by
loosening the bolt to drop or raise one side from the other). Then tighten all four slider bolts and nuts.
4. Check your closure position when the lift is in a closed position The ceiling closure should close tightly
but not bent or distorted.
