Abstract
A hoist system includes a hook; a cable connected to the hook; a motor configured to move the hook and the cable; an overload protection device (OLPD) configured to limit loads imparted on one or more of the hook, the cable, and the motor. The hoist system further includes an emergency brake system configured to stop movement of at least the cable, where the emergency brake system is configured to operate in response to a manual control or automatically in response to a controller.
Claims15
A hoist system comprising:
- a hook;
- a cable connected to the hook;
- a motor configured to move the hook and the cable;
- an overload protection device (OLPD) configured to slip at a certain torsional range and allow the cable to reel out in order to limit loads imparted on one or more of the hook, the cable, and the motor;
- and
- an emergency brake system configured to stop movement of at least the cable,
- wherein the overload protection device (OLPD) comprises an OLPD activation sensor configured to generate an activation signal;
- wherein the emergency brake system is configured to be actuated by an actuation mechanism in response to one of the following:
- a manual control by a pilot and/or a crew in response to the activation signal or automatically by a controller in response to the activation signal;
- and
- wherein the emergency brake system includes brake components;
- wherein the overload protection device (OLPD) is configured to receive a torque from the motor and at the certain torsional range, the Overload Protection Device (OLPD) prevents torque from being delivered to the cable;
- and
- wherein the emergency brake system is configured to operate only when aircraft flight is detected.
