Device for determining weight of objects being moved
First Claim
1. A loading device for engaging an object to be moved at two points on the object and determining its weight while lifting it comprising:
- (a) a boom pivotally mounted on a base for horizontal and vertical movement;
(b) means operatively connected to said boom to cause said vertical movement;
(c) grapling means for grasping the load to be moved by said device at a point intermediate its ends;
(d) load cell means responsive to the weight of the load lifted by said device pivotally interposed between and interconnected with said grapling means and one end of said boom for measuring the weight of said load when lifted vertically by said device;
(e) means disposed on said boom intermediate of said grapling means and said base for engaging an end portion of said load engaged by said grapling means when said load is lifted;
said engaging means being connected to said boom by load pin means for measuring the pressure exerted against said means during said lifting;
(f) respective load indicator means remotely connected to said load cell means and said load pin means to register respectively the downward force on the load cell means and the upward force on said load pin means during lifting; and
means for determining the weight of load being lifted from the combination of said registered downward and upward forces.

Abstract
A device is described for determining the weight of objects being moved or loaded either individually or cumulatively. The device of the invention is particularly adapted for use with loaders such as the knuckle boom loader used for moving logs, poles and beams. An advantage of the invention is that it can be employed in conjunction with current models of loaders without requiring extensive modification of the loader device and can quickly and easily be removed when not needed. In one embodiment of the invention, heel means are provided for assisting in the moving and simultaneous weighing of large irregularly shaped objects such as logs and poles.
