Abstract:
1. A wireless lift system for coordinated lifting of a structure and comprising: (a) a first lift mechanism and a second lift mechanism; (b) each of said first and second lift mechanisms including an elongated vertical guide member, a carriage slidingly engaged with said guide member and adapted to supportively engage a structure to lift and/or lower the structure, an actuator engaged between said guide member and said carriage, a controller coupled to said actuator and enabling selective activation of said actuator to thereby move said carriage along said guide member, and a rechargeable battery coupled to said actuator by way of said controller to thereby selectively provide operating power thereto; (c) each lift mechanism including a radio-frequency transceiver coupled to the controller associated therewith to enable wireless communication between controllers of said lift mechanisms; and (d) the controllers of said lift mechanisms enabling cooperation of said lift mechanisms by way of said wireless communication between said controllers to thereby enable coordinated lifting and/or lowering of said structure.
