PLACING THE HDSWG 1000 MECHANICAL UNIT
Remove the rain seal from the shaft of the HDSWG 1000. SAVE
IT! The rain seal will be used later. Next, remove the cover from the
HDSWG 1000 MECHANICAL UNIT by removing the 1/4 inch
diameter bolts on each side of the Unit and set it aside. It is one of the
last items that will be replaced at the completion of the installation.
The recommended procedure for attaching the HDSWG 1000
MECHANICAL UNIT to the concrete pad (for those installations
where the anchor bolts were not previously installed) is first to locate
and drill the hole for the mounting hole nearest to the gate post. Locate
this hole by referring to the diagram in Figure 6. After placing a bolt in
the hole, mark and drill the remaining three holes. This can be
accomplished with the operator in place.
Before inserting the concrete bolts, make sure the HDSWG 1000
MECHNAICAL UNIT is level. If any corners of the HDSWG 1000
are resting above the pad, flat washers may be inserted under the
MECHANICAL UNIT. Place the flat washers, lock washers and nuts
on the concrete bolts and tighten securely.
For previously placed anchor bolts, the procedure is the same except
that the bolts will already be in place. If 1/2" diameter anchor bolts
were set, the 3/4" mounting holes on the HDSWG 1000
MECHANICAL UNIT will allow some adjustment for desired
alignment. Washers can be used under the HDSWG 1000
MECHANICAL UNIT to accurately level the unit as above.
TO REVIEW: Make sure the correct position of the HDSWG 1000
MECHANICAL UNIT from the center line of the gate hinge pivot
point to the center line of the HDSWG 1000 is in accordance with the
drawing of Figure 6.
INSTALLING THE HDSWG 1000 ARM
Temporarily locate the Gate Bracket on the Gate with C-clamps or
by tack welding. Install the gate bracket to the gate so the gate
arm will be level when connected to the HDSWG 1000. See
Figure 9 for positioning of the Gate Bracket.
Loosen the adjustment nut of the Torque Limiter located on the top
of the Gear Box on the HDSWG 1000 MECHANICAL UNIT with
the 1-5/8 hex socket. This is done by removing the small set screw
on the large nut and loosening the nut.
For the installation shown in Figure 9, attach the Crank Arm
Extension to the Crank Arm with the (2) 1/4-20 x 1-1/2” long bolts
provided. The overall length of the cranking arm is now 33 5/8”
from the center of the Output Shaft to the center of the povot at the
“elbow.” Note that the cranking arm is adjustable to (5) possible
settings: 32-1/8”, 30-5/8”, 29-1/8”, 27-5/8” and 26-1/8” long.
Install the Crank Arm and Extension on the HDSWG 1000 main
shaft and make sure the Crank Arm swings freely from side to side.
Connect the Gate Arm to the Crank Arm Extension and the Gate
Bracket. With the Gate in the closed position, the "elbow" will be
up against the closed position stop on the Crank Arm Extension.
The Gate should be in the properly closed position. (See
Figurez9.)
Loosen the Stop Pall on the large output drive spocket located on
the output shaft on the HDSWG 1000 MECHANICAL UNIT. (See
Figure 10.) Move the Gate to the fully open, 90 degree position.
The Arm extension should fold back over the arm as shown in
Figure 9. If it doesn't, some adjustment of the gate bracket or
operator position may be necessary. With the gate in the fully
open position, adjust the stop pall on the sprocket against the stop
on the HDSWG 1000 frame and tighten the set screw. Open and
close the gate several times until you are satified that the arm
position is correct. Finish welding or bolting the Gate Bracket to
the Gate and remove the C-clamps.
