Abstract
A self-balancing synchronization assembly has a support beam pivotally mounted on a guide rail adjacent a hydraulic elevator jack. A synchronization bracket is pivotally mounted at one end of the beam and a pair of synchronization cables is connected between the bracket and a telescoping part of the jack. A return cable is connected between the other end of the beam and the hoistway pit to balance the load and includes a turnbuckle for retensioning the synchronization cables. A second synchronization bracket can be pivotally mounted at the one end of the support beam to synchronize a three-stage jack.
