Crawler - Transporter
Traveling 1 mph, the crawler carries the launch vehicle with its mobile launcher platform to the launch pad using a laser guidance system and lowers them both onto the pad pedestals. After the launch, the crawler re-lifts the mobile launcher and returns it. Each transporter travels on eight tracked tread belts containing 57 tread belt "shoes."
One crawler houses 16 traction motors, two AC and two DC generators, and two control cabs that drive the vehicle forward and backward. The jacking, equalizing, and leveling (JEL) system keeps the upper deck and pickup points level at all times, even when traveling at an incline, to prevent the payload from toppling.
NASA's Ground System Development and Operations Program (GSDO) has been refurbishing the crawlers since the last space shuttle
