Abstract
A mobile floor crane has a tubular, rigid stanchion that supports a boom pivotally connected to the top end of the stanchion. The base end of the stanchion is disposed between the adjacently disposed mid portions of the tubular, rigid legs of the crane. A support member extends transversely through the mid portions of the legs and the base end of the stanchion and supports the stanchion. In an alternative embodiment, the legs have telescoping members, and a rolling member is provided on the base end of the stanchion to provide mobility for the crane when the telescoping members are detached for storage.
