Abstract
A method, device and system are provided that is a portable lifting system for easy movement of moderately heavy items, including a base member, a vertical support member connected to the base member and a load member slideably connected along the vertical support member. The system is typically small in size, allowing for ease of loading, lifting, transporting and unloading of moderately heavy objects of 25 to 100 pounds. The system is typically used in enclosed areas such as an office, home, workshop, garage or basement. The actual load member varies depending upon the type of load being lifted. A common type connector is used allowing interchangeability between the various load members. The system can further include a mechanical advantage member including a screw or a motor to control load member height. The mechanical advantage member may be controlled manually, or electronically.
