ENSURE CANTILEVER ARMS ARE SQUARE AFTER
TIGHTENING.
If supplied, attach the under-platform obstruction sensor plate to the cantilever arms. Use
the four (4) 1/4" (6 mm)-20 x 1 3/4" (44 mm) bolts, flat washers, plastic spacers, spring
nuts and lo
4)
ck nuts provided. See Figure # 6.
5) To ensure that the under-platform obstruction sensor does not contact the switches on
the cantilever arms, use the mounting bolts to adjust the sensor. The sensor plate should
clear the sensor switches by 1/8” (3 mm).
NOTE
The under pan obstruction sensor plate attaches to the cantilever arms, not to the platform.
Install the plate before the platform.
6) Install the platform onto the sling. The platform and cantilever support arms are furnished
with an adjustable mounting plate, allowing adjustment of the platform to match the site
conditions. The mounting plate is located between the two sets of cantilever arms,
equipped with 1/4" (6 mm)-20 clinch nuts. Access the nuts through slotted holes in the
upper flange of the cantilever arms. The slots should provide approximately 1/2" (12 mm)
of movement in or out from the tower to align the platform with site conditions. Insert the
two (2) bolts underneath the control wall into the two holes in the sling assembly. See
Figure # 8.
7) For shipping purposes, the adjustable mounting plate is held in position by six (6) 1/4"
(6 mm) hex-head bolts. Remove and discard the bolts before positioning the platform.
Position the platform by aligning the threaded holes with the platform hole pattern. Install
six (6) 1/4” (6 mm) x 3/4” (19 mm), stainless steel, flat head mounting screws sent with
the shipment.
DO NOT TIGHTEN MOUNTING SCREWS UNTIL THE
PLATFORM HAS BEEN PROPERLY ALIGNED WITH
LANDING SILL AND/OR HOISTWAY WALLS.
NOTE
A) Make sure the platform is square to the landing sills, and running clearance is in
accordance with local code requirements.
B) If the tower has been installed plumb and square, the platform will be level unless there is
excessive play in the guide shoes. Shim the guide shoes, if required. Shimming the
platform is not recommended.
C) If an automatic ramp is attached to the p , see the “AUTOMATIC RAMP” section of latform
this manual.
