Abstract
A ladder lift is provided. The ladder lift may include a foldable platform, a frame, a motorized gear mechanism, a gear channel and a toggle switch. The gear channel may extend upwardly from a supporting surface along the length of the frame. The gear channel may house a belt track extending along the length of the gear channel. The foldable platform may be rigidly connected to the motorized gear mechanism. The motorized gear mechanism may selectively engage the belt track for causing the foldable platform to move in a specified direction along the length of the gear channel. The toggle switch may be used to engage and disengage the motorized gear mechanism. The frame may support the gear channel, the foldable platform, the motorized gear mechanism and a user. The user may be accommodated on the foldable platform. Then the user may activate the toggle switch so that the foldable platform moves in a specified direction along the length of the gear channel for a predetermined distance.
