Adjustable mobile machine base systems and methods

摘要

An adjustable mobile base that accommodates machines of different effective footprints and allows them to be selectively moved from place-to-place or fixed at a given location. The mobile base assembly comprises a frame assembly comprised of corner members and side members. The side members are telescopically received within the corner members such that a width dimension and depth dimension of the base assembly can be changed to accommodate machines having different effective footprints. A lock system may be provided which employs one or more lock assemblies. Each lock assembly comprises a lock member that is slidably received within a lock housing and a drive member which is threadably received within the lock housing. Rotating the drive member in one direction elevates one or more wheels of the base assembly and thus frictionally engages the floor surface and prevents movement of the machine on the base assembly. Turning the drive member in the opposite direction allows the stop member to be retracted up into the housing assembly. In this unlocked position, the weight of the machine is borne by wheels that allow the machine to be rolled from one location to another.
