6. BASIC CONSTRUCTION The traverse frame is of rolled steel welded construction The frame consists of two trucks rigidly bolted to the hoist The traverse is driven by a motor and gear box attached to one truck This drives the truck axle by a hollow shaft keyed to the axle INSTALLATION GENERAL Bridge girders on which these traverses will operate must be amply strong to support traverse hoisting equipment and rated load Traverse rails should be level and parallel within 1 4 Rail joints must be smooth and held firmly in alignment either by bolted splice bars or welding Rails should be securely fastened to the bridge girders INSTALLING The installation of the traverse on the crane shall be performed only by qualified installer For information regarding attaching lifting and moving the loads during installation refer to ANSI B30 2 0 Section 2 3 2 and other applicable codes Page 6 Consult the Manufacturer for the traverse weight and other required information before attempting installation Before installing traverse on bridge lock runway conductor disconnect switch in open power off position Total weight of traverse and hoist should be checked against lifting equipment selected for erection of traverse Immediately after traverse is placed on the traverse rails check wheel flange clearances to the rail Clearance between side of rail head and inside flange of wheel will be 1 4 for a 25 ASCE traverse rail
