A manually operated counterweight hoist including a batten operable to support a load, an arbor operable to support one or more counterweights, a hand line operable to move the batten or the arbor, a brake operable to prevent movement of the arbor and the batten by constricting movement of the hand line, a brake actuator operable to activate the brake, a sensor that measures a speed of the arbor, and a controller including an electronic processor. The controller is operatively coupled to the sensor and the brake actuator. The controller is configured to receive a measurement signal from the sensor, determine whether the speed of the arbor exceeds a threshold based on the measurement signal, and activate the brake actuator when the speed of the arbor exceeds the threshold.
