A vertical lift system having a safety brake assembly (10) employing a pair of brakes attached to cables running vertically on each side of a guiderail (1). Each brake has a series of wedges (13, 14, and 15), including a braking wedge (14) that presses against the guiderail to brake downward motion of an elevator or lift basket upon an interruption in cable tension. A cable tension adjustment mechanism (3, 4 and 6) to equalize tension in the cables is also incorporated into the safety brake assembly. An electrical sensor (18) is also provided to disrupt power to the lift system upon slackening of a cable.
