Abstract
A mechanical lift includes a housing defining a series of vertical adjustment notches, an adjustment block disposed within the housing, a hook extending from the adjustment block and configured to support a hanging load, a stopper supported by the adjustment block and movable between retracted and extended positions, and a spring disposed within the housing and exerting an upward force against the adjustment block to mechanically lift the adjustment block and the hook extending therefrom from a first vertical position at a first notch of the series of vertical adjustment notches to a second notch of the series of vertical adjustment notches when the stopper is in the retracted position. In the retracted position, the stopper is disengaged from the housing. In the extended position, the stopper is engaged with a selected notch to lock a vertical position of the adjustment block and the hook extending therefrom.
