This paper deals with the backward stability of a truck crane the carrier of which is supported by outriggers during crane working. Assuming the carrier to be supported elastically by four outriggers on the ground and the carrier frame to be deformed elastically, the behaviour of the truck crane overturning in the backward direction while in the unloaded condition has been theoretically analyzed. Further, an equation of motion of one degree of freedom has been made for a simplified model of the truck crane, and an approximate solution has been obtained. Thus the minimum acceptable backward stability of a truck crane can be easily determined for any carrier dimension and specification.
