    Abstract: A zero-gravity hoist system including a chain fall, a motor coupled to the chain fall and configured to drive the chain fall in one or more directions, a power supply configured to provide power to the motor, and a controller having one or more electronic processors. The one or more electronic processors are configured to measure a first force of a load in response to receiving an input, store the measured first force in a memory of the controller, measure a second force of the load, determine a difference between the second measured force and the first measured force, and adjust a height of the load based on determining that the second force differs from the first force by a predetermined threshold.
