CONCEPTUAL CONSTR. SEQUENCE

SHEET 3 OF 3

NOT FOR CONSTRUCTION

CONCEPTUAL CONSTRUCTION SEQUENCE:

1.) ENSURE TRAVELER EXTENSIONS ARE LOCKED IN THE FULLY

RETRACTED POSITION, AND SECURE EXTENSIONS TO ENSURE

THEY DO NOT MOVE IN FUTURE STEPS. MOVE THE TRAVELER

AND POSITION IT DIRECTLY BENEATH THE FLOORBEAM

NEAREST TO THE ANCHOR PIER (SEE IMAGE, THIS SHEET).

2.) TEMPORARILY SUPPORT THE TRAVELER BY FIXING THE MAIN

TRUCK CHANNELS TO THE TRAVELER RAILS AT THE ENDS OF

EACH TRUCK (FOUR LOCATIONS TOTAL) USING THE

TEMPORARY SUPPORT DETAILS SHOWN ON SHEET 2. TIGHTEN

NUTS TO RELIEVE LOAD FROM THE WHEEL ASSEMBLIES.

3.) REMOVE THE WHEELS, WHEEL BEARING ASSEMBLIES, AND

MOTORS BY REMOVING THE 1 1/2" DIAMETER THROUGH-BOLT

(SEE IMAGE, THIS SHEET). DO NOT DAMAGE TROLLEY PLATE

DURING REMOVAL OPERATIONS.

4.) REMOVE STOP BLOCKS (SEE IMAGE, THIS SHEET).

5.) INSTALL CABLE SYSTEM AND ASSOCIATED HARDWARE

SHOWN ON SHEETS 1 AND 2.

6.) ONCE CABLE SYSTEM IS ATTACHED, LIFT SLIGHTLY TO

RELIEVE LOAD FROM TEMPORARY SUPPORTS. REMOVE

TEMPORARY SUPPORTS.

7.) SLOWLY AND CAREFULLY LOWER TRAVELER TO GROUND

USING CABLE SYSTEM.

8.) DISCONNECT CABLE SYSTEM FROM TRAVELER AND BRIDGE.

DISCARD TRAVELER. FILL ABANDONED HOLES IN BRIDGE WITH

PRETENSIONED HIGH STRENGTH BOLTS.
