Abstract
A yoke assembly for suspending an elevator car or a counterweight in a shaft of an elevator has a yoke adapted to be mechanically coupled to the elevator car or the counterweight. The yoke has a height with respect to a height axis and a length with respect to a longitudinal axis orthogonal to the height axis; a pulley for suspending the yoke, wherein the pulley has a diameter equal to or less than the height of the yoke and is attached to the yoke so as to be rotatable about an axis of rotation whose position with respect to the height axis is such that the pulley does not protrude beyond the yoke in either direction of the height axis; wherein, when the yoke is suspended in the shaft, the height axis is a vertical axis and the axis of rotation is a horizontal axis.
