Autoquip BASCULE BRIDGE - DOUBLE LEAF - Manual (Page 14)

DANGER!
INSTALLATION INSTRUCTIONS
NEVER go under the bridge until the load is removed and the bridge is
securely blocked. See “Blocking Instructions” section in this manual.
BRIDGE (See Figures 9 through 13)
1. Set the bridge in the correct horizontal position (on “horses” or temporary welded
supports). Line up accurately with the dock and hinge channel.
NOTE: Hinge channel and clevis channel MUST be set plumb, square, and parallel
by the pit contractor.
2. Tack-weld the male hinge clevises securely in place. Remove the hinge pins and
raise or lower the bridge enough to expose the clevises for full welds. Weld securely
5/16” inch fillets all around (shim between the imbedded channel and the clevises, if
required).
3. Grease the hinge pins and reset the bridge on the hinges.
LIFTING CYLINDERS (See Figure 14)
4. Bolt the cylinder base clevis to the tapped clevis block using only two of the ¼”
thick shim plates between them. Connect the cylinder to the bridge clevis and the
base clevis.
5. Line up the clevises and rams accurately, with the bottom clevis-pin-centerline
exactly 15 ¾” out from the hinge channel face. Weld the clevis blocks to the base
channel, 5/16” fillets all around.
POWER UNIT (See Figures 15 and 16)
6. The power unit can be mounted in any area that is less than 12 feet above the
bridge and less than 30 feet away from the bridge, and is protected from the
elements. The power unit must be lagged down. The electrical work is to be done
in accordance with local codes by a qualified electrician. See the electrical
schematic in the Maintenance section of this manual for proper electrical installation.
7. Check the motor rotation for proper direction. Switch the leads if necessary to
change the motor direction. NOTE: Precautions must be taken to collect fluid
pumped from the reservoir when checking the motor rotation.
8. Fill the power unit reservoir with fluid as per the instructions in the “Maintenance”
section.
