No, this isn’t used for clearing snow. The crawler-transporter that will carry NASA’s Space Launch System (SLS) and Orion spacecraft to Launch Pad 39B for launch on Exploration Mission-1 in 2017 recently passed the first phase of an important milestone test at Kennedy Space Center in Florida. Testing of new traction roller bearings on crawler-transporter 2 (CT-2) was completed in late January. The new roller bearing assemblies that were installed on one side of the crawler are visible in this Jan. 31, 2014 image.
For more than 45 years the crawler-transporters were used to transport the mobile launcher platform and the Apollo-Saturn V rockets and, later, space shuttles to Launch Pads 39A and B. Upgrades to CT-2 are necessary in order to increase
the lifted-load capacity from 12 million to 18 million pounds to support the weight of the mobile launcher and future launch vehicles, including the SLS and Orion.
