Abstract
A lift system having a first pulley and a biasing member having a first portion operatively coupled to the first pulley. A first tension member can be operatively coupled to the first pulley. The lift system may be configured to provide a constant force to the first tension member during a defined angle of rotation of the first pulley. Such a constant force can be used to counterbalance the weight of a display supported by a stand.
