Abstract:
1. A lift system comprising: a backbone; a motor assembly; a drive shaft; and a first drum section; wherein: the motor assembly includes a universal joint connector and backbone connector hardware; the backbone connection hardware mechanically connects the motor assembly to the backbone; the drive shaft includes a first universal joint connector and a second universal joint connector; the first universal joint connector of the drive shaft is directly mechanically connected to the universal joint connector of the motor assembly so that rotation of the universal joint connector of the motor assembly will drive rotation of the drive shaft about an at least substantially common axis of rotation; the first drum section includes a first universal joint connector and a drum surface; the drum surface of the first drum section is sized, shaped, structured and/or located to wind and unwind a cable therefrom; and the second universal joint connector of the drive shaft is directly mechanically connected to the first universal joint connector of the first drum section so that rotation of the drive shaft will drive rotation of the first drum section about an at least substantially common axis of rotation.
