Abstract: A stretcher supporter, and a method of balancing a stretcher supporter for a patient lifting device, are disclosed. The stretcher supporter includes an open frame, wherein said open frame provides for secure attachment of a stretcher to said open frame and an adjustable lifting point connected to said open frame, wherein said adjustable lifting point suspends said open frame and rotatably shifts to substantially balance said stretcher respective to said open frame. The method of balancing a stretcher supporter for a patient lifting device, includes the steps of securely attaching a stretcher to an open frame of said stretcher supporter and adjusting a lifting point connected to said open frame, wherein said adjusting a lifting point suspends said open frame and linearly and rotatably shifts to substantially balance said stretcher respective to said open frame.

Abstract: A computerized controller that limits the movement of a patient lifting device, wherein the controller is operated in a normal mode to sense the lateral rotation of a lifting arm that lifts patients and the linear displacement of extendable support legs for said lifting device and the angular diversion of said support legs. The controller inhibits movement of said lateral rotation of a lifting arm in response to the linear displacement and the angular diversion of the support legs to prevent tipping the lifting device. The same controller may be operated in a bypass mode to override the normal mode wherein the patient lifting device may be operated during a setup and breakdown operation to permit construction and disassembly of the patient lifting device.
