Automated system for load acquisition and engagement
A method for automatically guiding a lifting device on a lifting apparatus to a lifting point on a load is disclosed. A beacon is associated with the lifting point on the load has a plurality of lights arranged in a predetermined pattern. A sensor on the lifting apparatus detects the lights and provides signals to a processor. The processor calculates location of the lifting point, and develops signals that directs the lifting apparatus, or an operator of the lifting apparatus, to engage the lifting point with a lifter on the lifting apparatus. The load may then be lifted and moved.
1. A method of locating and picking up a load, comprising:
associating a display comprising a plurality of lights with at least a location of at least one load lifting point on a load to be transported by a load lifting apparatus,
on said load lifting apparatus, using a computer to convert said light from said display into electrical signals representative of at least distance and direction from a load lifter of said load lifting apparatus to said load lifting point,
directing said load lifter of said lifting apparatus to said load lifting point using said electrical signals representative of at least distance and direction,
engaging said load lifter with said load lifting point,
picking up said load.
2. The method as set forth in claim 1 further comprising connecting an automated grapple to said load lifting apparatus, and connecting a receiver for said automated grapple to said load, said receiver being the lifting point associated with said display.
3. The method as set forth in claim 2 further comprising offsetting said display from said receiver.
4. The method as set forth in claim 2 further comprising using an electrically powered grapple to extend a plurality of latches into said receiver, locking said grapple into said receiver without assistance from a person.
