A winch is disclosed having a drive cylinder, configured to be rotated by an applied force about its longitudinal axis and having at least three drive grooves. The winch also includes an idler with a longitudinal axis spaced apart from the longitudinal axis of the drive cylinder. A line is fed onto the winch by passing it over a first of the at least three drive grooves then around the idler and then around a second of the at least three drive grooves. The line is attached to one of a fixed object or the object to be moved. The winch is attached to the other of the fixed object or the object to be moved. As the applied force is applied to the drive cylinder, the line is gripped by the at least three drive grooves and a length of the line between the fixed object and the object to be moved is shortened, whereby the object is moved.

An embodiment of a method of moving a motor within an enclosure of an air handler of a climate control system includes (a) suspending the motor from a first lifting support and a second lifting support via lifting line, the first lifting support being laterally spaced from the second lifting support in the enclosure. In addition, the method includes (b) shortening the lifting line extending between the motor and the second lifting support. Further, the method includes (c) lengthening the lifting line extending between the motor and the first lifting support. Still further, the method includes (d) moving the motor laterally within the enclosure as a result of (b) and (c).

A method of controlling operation of equipment that spools cable on and off a rotatable drum, in one or more embodiments, includes obtaining video data of a position of the cable on the rotatable drum. The method can also include feeding data into a trained artificial neural network and processing the data fed into the trained artificial neural network to determine at least one of a calculated position of the cable on the rotatable drum, a calculated fleet angle, or both. The method can also include actuating the rotatable drum to one of spool cable on and off the rotatable drum.

A portable self-tailing winch and rigging bollard device that contains a self-tailing winch and a rigging bollard that are permanently fixed on a rigging plate. Other options include fairleads for rigging lines and ports for additional rigging attachments. The rigging plate is portable and can be easily anchored to any suitable structure located either inside or outside of a building. The self-tailing winch and rigging bollard can be operated by a single individual to control the tension of rigging lines for safely re-positioning or holding a load. For optimal safety, both the self-tailing winch and rigging bollard are fastened to the load and synchronously operated with fairleads to maintain or alter position of the load to a desired location.
