    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.

    Abstract: A charging module is configured to be removably coupled to a mobile work cart. The charging module includes a housing having a first end, a second end, a front side, and a rear side. The housing defines a cavity in the front side and includes a charging bay located within the cavity. The charging bay is configured to removably receive a battery pack to electrically connect the battery pack to the charging module. The charging module also includes a clamp coupled to the rear side of the housing. The clamp includes a handle portion and an arm. The clamp is movable relative to the housing between a deployed position and a retracted position. The clamp is biased toward the retracted position. The housing defines a recess in the rear side. When the clamp is in the retracted position the arm is received within the recess.
