A hydraulically-operated actuator for a braking mechanism on a cable drawworks is provided. The actuator can have an enclosed tubular main body capable of being connected to an external hydraulic system. The main body can further contain a spring-opposed hydraulic piston connected to an actuator rod. The actuator rod can extend out of the main body and can connect to a braking system for the drawworks. In operation, the springs can push on the hydraulic piston and hold the actuator rod in a fully extended position to engage the braking system. When pressure from the external hydraulic system is applied to the hydraulic piston, the hydraulic piston can compress the springs and retract the actuator rod into the main body, which can disengage the braking system.
