Abstract
The present invention provides a lift system comprising a drum that rotates about an axis, a drive mechanism operable to rotate the drum about the axis, an elongate member (e.g., a cable) having a wound portion wound around the drum and a vertical portion extending downward to the article being lifted, and a low profile adjuster for adjusting a vertical length of the elongate member. The low profile adjuster comprises a first guide adapted to support the article to be lifted and including a first pathway, and a second guide movable relative to the first guide. The elongate member transitions from the vertical portion, through the first pathway to a non-vertical (e.g., horizontal) portion, and to the second guide. Adjustment of a distance between the first guide and the second guide results in adjustment of a vertical position of the first guide relative to the elongate member.
