Abstract

See full text

A lift assembly comprises a base, a drive mechanism, a flexible drive element extending from the drive mechanism along a fleet axis, and a sheave directing the drive element from the fleet axis to an output axis. The sheave is coupled to the base at a first sheave mount aligned with the fleet axis. The assembly can further include a second sheave mount aligned with the fleet axis and configured to be coupled to the sheave to allow the sheave to be de-coupled from the first sheave mount and coupled to the second sheave mount, resulting in substantially no change in a fleet angle of the fleet axis. Preferably, the sheave is positioned on a first side of the fleet axis when coupled to the first sheave mount, and the sheave is positioned on a second side of the fleet axis (e.g., opposite the first side) when coupled to the second sheave mount.
