摘要:
An improved brake for winches. The brake has a main brake and an emergency brake. Both brakes are solenoid operated and brake when the power is turned off or fails. Means are provided for slightly delaying the operation of the emergency brake compared to the main brake so that the braking force is applied in stages in an emergency. The brakes are mechanically linked together so that either of the main or emergency solenoids operate both brakes if one of the solenoids fails.
