1. A beehive lifting device (10) which comprises:
- first (72a) and second (72b) lifting lugs intercepting a first plane (86), and being spaced apart a first distance (88) in said first plane;
a load attaching member (16) having a load lifting point (51) and an attaching portion (50);
folding frame means (12), being operatively attached to said lifting lugs, and being operatively attached to said attaching portion of said load attaching member, for placing said load lifting point substantially in a second plane (90) that is orthogonal to said first plane and that bisects said first distance, for spacing said load lifting point distally from said first plane, for selectively adjusting said first distance between said lifting lugs, and for maintaining said load lifting point substantially in said second plane irrespective of said selective adjustments to said first distance; and
said beehive lifting device includes resilient means for resiliently urging a reduction in said first distance.

Abstract
A beehive lifting device (10) lifts beehives (106) by engaging handholds (124). As the beehive (106) is lifted by the lifting device (10), the relationship between the load lifting point (51) and the center of gravity (110) of the beehive (106) causes the beehive lifting device (10) to tilt backward, and causes the beehive (106) to tilt backward toward, or against the folding frame (12) of the beehive lifting device (10). The beehive lifting device (10) is foldable either into a flat package that is disposed parallel to a fourth plane (94) or into a compact bundle that is disposed substantially around an axis (98).
