A random vibration system model of "road-crawler type vehicle-operator" is needed for the analysis of dynamic characteristics of new type viscoelastic crawler construction machinery.

The trip from the Vehicle Assembly Building to the launchpad takes about five hours, and the crawler burns about 150 gallons (570 liters) of diesel fuel every mile.

Products include excavators, vehicle cranes, crawler cranes, loaders, motor graders, bulldozers, rollers, forklifts, such as hanging harbour.
