Abstract
A lift assembly comprising a plurality of elongate members (e.g., cables) positioned for movement in a longitudinal direction, a drive mechanism (e.g., a drum) coupled to move the elongate members in the longitudinal direction, and a loft block including a sheave located to redirect at least one of the elongate members to a non-parallel path that is not parallel to the longitudinal direction, wherein a remainder of the elongate members travel along a parallel path that is above the sheave. The loft block can include an idler bar having an upper surface that is higher than an upper surface of the sheave. For example, the idler bar can be positioned directly above the sheave.
