Abstract
An attachment for use with a skid loader for lifting and transporting stacks of strapped blocks which includes a frame having an upper and lower horizontal bar, a pair of arms pivotally mounted with the upper bar which are in sliding engagement with the lower bar. A drive member is carried by the frame between the arms for moving the arms between a disengaged and an engaged position. A foot assembly which includes first and second legs and a grabber foot is connected with each of the arms. Each grabber foot includes a planar inner face and is pivotally mounted with a second leg to extend substantially perpendicularly of the associated arm with its inner face canting slightly upwardly and outwardly.
Claims17
Apparatus, which is operative with a loader, for lifting and transporting stacks of strapped blocks comprising:
- a frame having a horizontally extending upper bar;
- a mounting assembly, adapted to be releasably engaged with said loader, secured with a first side of said upper bar;
- a grabber assembly, for engaging and securing said strapped blocks with said apparatus, including downwardly depending first and second arms pivotally mounted about generally horizontal axes with said upper bar, said first and second arms each having a longitudinally extending axis;
- a piston assembly arranged between and engaged with each of said first and second arms, said piston assembly being operative to pivot said first and second arms about said generally horizontal axes between an outwardly disengaged position and an inwardly engaged position;
- a foot assembly located generally forward of lower ends and in opposed outward positions of said first and second arms, each said foot assembly including a pivotally mounted grabber foot disposed transverse of the longitudinal axis of each respective first and second arm;
- whereby,
- said apparatus, with said arms moved to said disengaged position, may be moved into position adjacent a stack of strapped blocks with said foot assemblies located outwardly of opposed sides of said stack of strapped blocks, said arms may then be moved into said engaged position engaging said grabber feet with said opposed sides of said stack of strapped blocks, said apparatus may then be raised lifting said stack of strapped blocks, said apparatus may then be moved into a spaced position where said stack of strapped blocks may be deposited.
An attachment for a skid loader for lifting and transporting stacks of strapped blocks comprising:
- a frame having an upper and lower bar;
- said frame including a pair of arms pivotally mounted with said upper bar and supported in sliding engagement with said lower bar;
- a drive member carried by said frame between said pivotally mounted arms for moving said pivotally mounted arms between disengaged and engaged positions;
- a foot assembly including first and second legs and a grabber foot connected in opposed positions with each said arm above its lower end outwardly and forward, its longitudinal axis;
- each said grabber foot having a planar inner face and being pivotally mounted with said second leg to extend substantially perpendicular of said longitudinal axis of the associated of said pivotally mounted arms with said inner face canting slightly upwardly and outwardly;
- whereby,
- when said attachment is positioned adjacent a strapped stack of blocks with said pivotally mounted arms in said disengaged position, said pivotally mounted arms are moved inward to said engaged position where said faces of said grabber feet engage opposed sides of said strapped stack of blocks and are moved to substantially vertical positions causing said second legs to torque.
