Abstract
Abstract A support mechanism for a selectively positionable control module for a load handling device such as a crane is provided. The support includes articulated inner and outer members and a parallelogram linkage. The control module may be raised, lowered, extended and retracted with respect to the crane body by manipulation of appropriate controls in the control module. The support mechanism is carried on a sub-frame which is pivotally mounted on the crane frame so that the control module may also be rotated with respect to the crane body. The control module may be lowered to the ground or onto a transport mechanism and can be quickly detached from the support mechanism.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
206 words
A support Mechanism for a selectively positionable control module for a load handling device having a frame on which a movable, load handling boom is mounted comprising, in combination: a subframe attached to the frame independent of the boom; an articulated support having inner and outer members pivotally connected at their remote ends to said subframe and the control module, respectively; means including a parallelogram linkage pivotally connected at its ends to said subframe and the control module, respectively, for maintaining said module substantially horizontally disposed as said support is raised, lowered and articulated; means including a first linear actuator pivotally connected at one end to said subframe and at the other end to said inner member for raising and lowering said articulated support and control module as a unit; and, means including a second linear actuator, a rocker arm and a link interconnecting said remote ends of said articulated support for folding said outer member and control module in and out with respect to said inner member, said rocker arm being interposed between said second actuator and said link and pivotally mounted on said inner member; whereby movement of said load handling boom may be controlled by a person operating controls in said control module.
Claim 2
Dependent Claim
206 words
A support Mechanism for a selectively positionable control module for a load handling device having a frame on which a movable, load handling boom is mounted comprising, in combination: a subframe attached to the frame independent of the boom; an articulated support having inner and outer members pivotally connected at their remote ends to said subframe and the control module, respectively; means including a parallelogram linkage pivotally connected at its ends to said subframe and the control module, respectively, for maintaining said module substantially horizontally disposed as said support is raised, lowered and articulated; means including a first linear actuator pivotally connected at one end to said subframe and at the other end to said inner member for raising and lowering said articulated support and control module as a unit; and, means including a second linear actuator, a rocker arm and a link interconnecting said remote ends of said articulated support for folding said outer member and control module in and out with respect to said inner member, said rocker arm being interposed between said second actuator and said link and pivotally mounted on said inner member; whereby movement of said load handling boom may be controlled by a person operating controls in said control module.
Claim 3
Dependent Claim
48 words
A support mechanism as defined in claim 1 wherein said subframe is mounted on a vertical pivot carried by the frame and means interconnecting the frame and said subframe is provided for swinging said articulated support, parallelogram linkage and control module as a unit about said vertical pivot.
Claim 4
Dependent Claim
40 words
A support mechanism as defined in claim 1 wherein said inner and outer articulated support members each include a pair of laterally spaced beams interconnected by cross-braces and said first and second actuators each include a pair of hydraulic cylinders.
Claim 5
Dependent Claim
44 words
A support mechanism as defined in claim 1 including a plurality of control conduits extending from the control module to said first and second actuators, and wherein said parallelogram linkage includes inner and outer channel-shaped members adapted to house and shield said control conduits.
Claim 6
Dependent Claim
24 words
A support mechanism as defined in claim 4 wherein a plurality of rollers are journalled within said channel-shaped members for supporting said control conduits.
Claim 7
Dependent Claim
42 words
A support mechanism as defined in claim 4 wherein said inner and outer channel-shaped members are pivotally interconnected to one end of a spacing link the other end of which is pivotally connected to said articulated support at the articulation point thereof.
Claim 8
Dependent Claim
36 words
A support mechanism as defined in claim 1 wherein said articulated support and parallelogram linkage are connected to said control module by a carrier frame and said carrier frame is detachably connected to said control module.
