Abstract: A drive mounting for an elevator of a scraper vehicle having a main drive shaft carrying a pair of driving sprockets coupled to an elevator drive unit at one side of the frame, in which the drive unit is mounted in a spherical type joint at one end thereof and is carried at the other end thereof by a resilient mounting carried in a vertical socket capable of limited swivel and pivotal movement. The resilient mounting also has a pivot along a horizontal axis offset from the drive shaft axis. This mounting prevents stresses from being set up therein when the drive unit is mounted, and also absorbs shock during operation. Means are also provided for holding the main drive shaft in place separate from its associated motor and gear drive to facilitate assembly and motor maintenance.
