Claims18
A gripping arm for a forklift truck, characterized in that:
- the gripping arm comprises an outer arm, a balance arm, an inner arm, and a rubber block;
- the rubber block is mounted on an inner surface of the inner arm, and mounting holes are disposed along a horizontal direction of an outer surface of the inner arm;
- a horizontal through-hole is provided along the horizontal direction of the balance arm, and on one side of the horizontal through-hole is provided a vertical through-hole;
- the balance arm can be mounted to swing vertically on the inner arm mounting holes by means of a horizontal pin passing through the balance arm horizontal through-hole, and the balance arm can be mounted to swing horizontally on a vertical through-hole of the outer arm by means of a vertical pin passing through the vertical through-hole of the balance arm.
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 first lower portion 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 arranged substantially coplanar with the first load face portion and engageable with the load distal of the lower first 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 load to be clamped;
- and
- (ii) an elongate second load face portion arranged to engage the load to be clamped and affixed spaced apart in a direction normal to a longitudinal axis of the first load face portion and substantially coplanar to 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 parallel to the longitudinal axis of the first load face portion.
