Abstract

A large self-propelled heavy duty mobile crane comprises a triangular support frame having a pair of spaced apart drivable steerable double bogies at its wide front end and a pair of spaced apart drivable steerable single bogies at its narrow rear end. The pair of front bogies are connected by an adjustable telescopic tie rod which maintains them either parallel or inwardly-toed, depending on the type of crane traverse and steering motion desired. A vertically swingable A-frame boom has its two spaced apart lower ends pivotally connected to the wide front end of the support frame directly above the attachment points of the front bogies to concentrate the load thereat. A vertically swingable inverted U-frame boom support mast has its two spaced apart lower ends pivotally connected to the wide front end of the support frame as close as possible to the boom attachment points.

Primary Examiner-Robert J. Spar Assistant Examiner-Lawrence J. Oresky Attorney, Agent, or Firm-James E. Nilles 57 ABSTRACT A large self-propelled heavy duty mobile crane comprises a triangular support frame having a pair of spaced apart drivable steerable double bogies at its wide front end and a pair of spaced apart drivable steerable single bogies at its narrow rear end. The pair of front bogies are connected by an adjustable telescopic tie rod which maintains them either parallel or inwardly-toed, depending on the type of crane traverse and steering motion desired. A vertically swingable A-frame boom has its two spaced apart lower ends pivotally connected to the wide front end of the support frame directly above the attachment points of the front bogies to concentrate the load thereat. A vertically swingable inverted U-frame boom support mast has its two spaced apart lower ends pivotally connected to the wide front end of the support frame as close as possible to the boom attachment points.

2. A self-propelled mobile crane comprising: a triangular support frame having a wide front end and a narrow rear end and a transverse beam attached at said narrow end; a pair of drivable and steerable front bogies connected to said frame at spaced apart connection points near the corners of said wide front end of said frame; a pair of drivable and steerable rear bogies mounted at opposite ends of said transverse beam; driving means and steering means for said front and rear bogies; and adjustable telescopic tie rod connected to and between said pair of front bogies to maintain them in specific relationship with each other for steering purposes; means for locking said tie rod in extended or retracted positions; a vertically swingable boom having two spaced apart lower ends pivotally connected to said front end of said support frame at boom attachment points above said connection points of said front bogies to concentrate a load thereat; and a boom support mast having its lower end connected to said front end of said support frame adjacent a line between said boom attachment points.
3. A crane according to claim 2 wherein said boom support mast comprises two spaced apart lower ends pivotally attached to said frame at mast attachment points adjacent said boom attachment points.
4. A self-propelled mobile crane comprising: a support frame having a center of rotation; a first pair of drivable and steerable bogies connected at spaced apart connection points near one end of said frame; each bogie in said first pair having a center of rotation; a second pair of drivable and steerable bogies connected at spaced apart connection points near another end of said frame; driving means for said first and second pairs of bogies; and adjustable telescopic tie rod connected to and between said first pair of bogies to maintain them in specific relationship with respect to each other for steering purposes; means for locking said tie rod in extended or retracted positions; a vertically swingable boom having two spaced apart lower ends pivotally attached to said frame at boom attachment points substantially directly above said connection points of said first pair of bogies; a boom support mast having its lower end attached to said frame adjacent a line between said boom attachment points, and steering means for said first and second pairs of bogies to enable said crane to be steered for rotation either about the center of rotation of said crane or about a center of rotation between said bogies in said first pair.
5.
