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.
