Abstract
A gripping arm for a clamping attachment for a forklift has a load engaging inner arm including portions defining a load face. The inner arm is pivotal about a first axis parallel to the load face and pivots about a second axis normal to the first axis to engage and secure a load.
Claims17
A gripping clamp for a forklift truck, the clamp comprising:
- (a) a first gripping arm including a first elongate block arranged to engage an elongate lower portion of a load, a longitudinal axis of said first block approximately parallel to a bottom surface of said load, and a second elongate block spaced apart from said first block in a direction normal to said longitudinal axis of said first block and arranged to engage a second elongate portion of said load more distant from said bottom surface of said load than any part of said lower portion, said first block and said second block fixedly defining a plane and arranged to pivot about said longitudinal axis of said first block and to pivot about a second axis substantially normal to said longitudinal axis of said first block and parallel to said plane defined by said first block and said second block;
- and
- (b) a second gripping arm including a third elongate block arranged to engage an elongate second lower portion of said load, a longitudinal axis of said third block approximately parallel to said bottom surface of said load, and a fourth elongate block spaced apart from said third block in a direction normal to a longitudinal axis of said third block and arranged to engage another elongate portion of said load more distant from said bottom surface of said load than any part of said second lower portion, said third block and said fourth block fixedly defining a plane and arranged to pivot about said longitudinal axis of said third block and to pivot about an axis substantially normal to said longitudinal axis of said third block and parallel to said plane defined by said third block and said fourth block;
- wherein said first gripping arm and said second gripping arm are movable together to clamp a load between said elongate blocks.
A load gripping arm for a forklift mountable clamping attachment, the load gripping arm comprising an inner arm having an elongate first load face portion movable to engage a lower portion of a load proximate a bottom surface of the load and a second load face portion spaced apart in a direction normal to a longitudinal axis of the first load face portion and fixedly arranged substantially coplanar with the first load face portion, the second load face portion engageable only with portions of the load more distal of the bottom surface of the load than any portion of the load engageable by the first load face portion, the inner arm arranged to pivot about a first axis parallel to the longitudinal axis of the first load face portion and arranged to pivot about an axis normal to the first axis and generally parallel to the plane of the first load face portion and the second load face portion.
A load gripping clamp for a forklift truck, the clamp comprising:
- (a) a first load gripping arm;
- and
- (b) a second load gripping arm movable toward the first load gripping arm to clamp a load therebetween, the first load gripping arm and the second load gripping arm each comprising:
- (i) an elongate first load face portion arranged to engage a lower portion of a load proximate a bottom surface of the load to be clamped;
- and
- (ii) an elongate second load face portion fixedly arranged substantially coplanar with and spaced apart from the first load face portion in a direction normal to a longitudinal axis of the first load face portion to engage another portion of the load to be clamped, all of said other portion of said load more distant from the bottom surface of the load than any part of the lower portion engageable by the first load face portion, the first load face portion arranged to pivot about a first axis approximately normal to the longitudinal axis of the first load face portion and substantially parallel to the plane defined by the first load face portion and the second load face portion and to pivot about a second axis substantially coincident to the longitudinal axis of the first load face portion.
