  2. A LITTLE ABOUT SARENS…

  3. BRIDGES ON THE MOVE… FIRST BRIDGE MOVE COMPLETED IN 1980 SINCE THEN WE COMPLETE ON AVERAGE 70 BRIDGES EVERY YEAR BRIDGE MOVES VARY FROM CONCRETE DECK ON STEEL, CONCRETE DECK ON CONCRETE GIRDERS, STEEL TRUSS BRIDGES, ETC. HEAVIEST BRIDGE MOVED IN U.S.- SAM WHITE BRIDGE IN LEHI, UT 354 FEEL LONG AND WEIGHING 4,200 KIPS

  4. SELF-PROPELLED MODULAR TRANSPORTERS (SPMT’s) • USUALLY SEE 4 KINDS OF SPMT’S USED IN THE US. • KAMAG (SARENS CHOICE) • GOLDHOFER • SCHEURLE • NICOLAS

  5. WHAT THE DESIGNER SHOULD KEEP IN MIND • SPMTS (KAMAG) COME IN CONFIGURATIONS OF 4 AND 6 AXLES. • EACH AXLE HAS A MAXIMUM CAPACITY OF ROUGHLY 79 KIPS • MUST CONSIDER SUPPORT STRUCTURE WHEN DETERMINING SPMT QUANTITY (WEIGHT). • SPACE CONFINEMENTS…..DO THE SPMT’S WORK WITH THE SPACE PROVIDED. • GROUND BEARING CONCERNS.

  6. SPMT BENFITS INCLUDE: COUPLING SIDE BY SIDE OR END ON END. FLEXIBLE STEERING. ACCURATE ALIGNMENT. CENTRAL CONTROL UNIT. DIAGONAL/CRAB DRIVE FROM 0°TO 110° CIRCLE DRIVE “CAROUSEL” AROUND THE CENTER OF THE CONFIGURATION.

  7. WHY SPMT’s OR ABC REDUCE USER COST ALLOW BRIDGE ERECTOR TO BUILD OFF SITE AND OUT OF TRAFFIC. MINIMIZE TRAFFIC IMPACT. FASTER COMPLETION TIME. INCLEMENT WEATHER HAS LESS IMPACT ON CONSTRUCTION SCHEDULE. GOOD INVESTMENT EVERY $1 SPENT ON ABC THER IS A $5 SAVINGS ON USER COSTS.

  8. HOW SARENS MOVES BRIDGES SUPPORT BEAMS CROSS-BRACING FOR LATERAL SUPPORT 610mm SUPPORT SPOOLS 12-AXLE LINES
