A stage hoist motor assembly includes a first electric motor including a first brake and a second electric motor including a second brake. The first electric motor and the second electric motor are stacked one atop the other within a common plane. A cable winch is rotatable about a winch axis and includes a cable winch shaft that is driven by the first and second electric motors through respective ones of a first drive coupling and a second drive coupling. A width of the motors is less than a width of the winch. Moreover, the motors are stacked one atop the other within a common plane to provide a compact foot print that is favorable to use in performance venue environments.

Described herein are methods and systems for picking up, transporting, and lowering a payload coupled to a tether of a winch system arranged on an unmanned aerial vehicle (UAV). For example, the winch system may include a motor for winding and unwinding the tether from a spool, and the UAV's control system may operate the motor to lower the tether toward the ground so a payload may be attached to the tether. The control system may monitor an electric current supplied to the motor to determine whether the payload has been attached to the tether. In another example, when lowering a payload, the control system may monitor the motor current to determine that the payload has reached the ground and responsively operate the motor to detach the payload from the tether. The control system may then monitor the motor current to determine whether the payload has detached from the tether.

Embodiments of the present disclosure describe methods and apparatuses for a load lifting system.

A power winch dual-spring brake device is a brake device installed in a rope wheel of a power winch includes a brake spring composed of a first brake spring and a second brake spring for producing a braking effect and a dual-spring mode of the mutual embedment in the dual-spring wire interval can reduce the possibility of deformation when force is exerted on a latch end, while reducing the possibility of generating high temperature and elastic fatigue, being broken or getting stuck to significantly improve the safety of use of the power winch.

A vehicle winch control assembly includes, among other things, a winch, and a vehicle input device that is reassigned to control the winch. The vehicle input device can be an accelerator pedal. A vehicle winch control method includes, among other things, reassigning a vehicle input device, and, after the reassigning, controlling a winch using the vehicle input device.
