Abstract
A trolley for use in a cable lift having a mast with a generally rectangular hollow cavity forming a track in which the trolley may be reciprocated upwardly and downwardly. The trolley is connected to a cradle outside the mast upon which an object to be lifted may be placed. The trolley has trolley wheels which make rolling contact with a front and back side of the track to resist a forward bending moment in down direction on the cradle. The trolley has spacer wheels which make rolling contact with a right and left sides of the track to resist a lateral bending moment on the cradle such that the cradle may be mounted on the mast offset from centerline.
