This electric hoisting machine comprises: a motor driven by single-phase current; a cylindrical motor housing; a starting capacitor; a operating capacitor; a starting capacitor disconnecting switch; a control unit which controls the operation of the motor and which is covered by a control housing; and a housing case in which small-diameter cylindrical portions for accommodating the starting capacitor, a large-diameter cylindrical portion for accommodating the operating capacitor, and a large-diameter cylindrical portion for accommodating the starting capacitor disconnecting switch are integrally provided in a state of continuing in a horizontal row, the housing case being mounted on the outer periphery of the motor housing in such a manner that the cylindrical portions are oriented parallel to a rotation axis.

A winch and method for operating the winch includes a winch body having a first drum support, a second drum support and a drum rotatably coupled to the first drum support and the second drum support. The winch further comprises a plurality of gears coupled to the second drum support and the drum. A motor is coupled to the drum through the plurality of gears. A motor cover is coupled to the first drum support. A gear cover is coupled to the second drum support and houses the plurality of gears therein. A supplemental cover covers at least a portion of the motor cover or a portion of the gear cover or both.

Devices, systems, and methods for varying rotational speeds is disclosed. A battery pack has a plurality of batteries and a switch. The battery pack has an overall voltage. The switch varies the overall voltage in discrete steps by combining the plurality of batteries in series, in parallel, or in a combination thereof. A motor drives a shaft at a rotational speed. The motor is powered by the battery pack. The rotational speed varies proportionally with the overall voltage.

A control system for a component of a rescue hoist attached to an aircraft is disclosed. In various embodiments, the control system includes a first bus extending between a control module of the rescue hoist and a control input device; a second bus extending between the control module of the rescue hoist and the control input device; and a hardwire extending between the control module of the rescue hoist and the control input device.

Disclosed herein is a controller of a hoist. The controller of a hoist includes a lift up button which is adjustable in a pressed degree; a lift down button which is adjustable in a pressed degree; lift up button contacts configured to allow ascending direction control power to flow to a motor when the lift up button is pressed; lift down button contacts configured to be in contact when the lift down button is pressed and allow descending direction control power to flow to the motor; a magnet accommodated in each of the lift up button and the lift down button; and a Hall sensor disposed to detect a descending degree of the magnet accommodated in each of the lift up button and the lift down button.

Embodiments of the present disclosure disclose a drive for an electric clutch if a winch. The drive comprises a pusher block having a first end, a second end, and a transmission component arranged on a central portion of the pusher block to drive a transmission shaft; a first driving unit connected to the first end to drive the first end to reciprocate between a first position and a second position; and a second driving unit connected to the second end to drive the second end to reciprocate between a third position and a fourth position. The drive enables switching of the transmission shaft between a high speed mode, a low speed mode, and an idle mode. A winch including the drive is also disclosed.

A portable winch system includes a frame, a pair of wheels, a motor that is secured to the frame; and a capstan that is secured to the frame and that is rotatable via the motor. A rope is wound about the capstan in a manner that enables a user to grasp a tail end of the rope and induce friction between the capstan and the portion of the rope that is wound about the capstan. A tow end of the rope is attachable to an object to be pulled by the winch. An input guide attached to the frame is configured to receive the rope and direct the rope toward the capstan as the object is pulled toward the winch. An alignment guide attached to the frame is configured to contact the rope and align the rope about the capstan as the rope is wound about the capstan.
