    Abstract: A working element operable to expand an end of a tube includes a main body configured to rotate about an axis, a plurality of roller supports movably coupled to the main body, the roller supports movable relative to the main body between a retracted position and an expanded position, and a plurality of rollers coupled to the roller supports such that a distance between a first roller of the plurality of rollers and a second roller of the plurality of rollers increases when the roller supports move toward the expanded position. The rollers are configured to be inserted into the end of the tube when the roller supports are in the retracted position, and the rollers are engageable with an inner circumference of the tube when the main body rotates about the axis to expand the end of the tube.

    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.

    Abstract: A power tool that includes an electric motor. The electric motor includes a plurality of stator windings, a plurality of switches for selectively coupling the plurality of stator windings in a first configuration or a second configuration, and a controller connected to the plurality of switches. The controller is configured to control the plurality of switches to configure the plurality of stator windings in the first configuration, monitor a condition of the power tool, and control the plurality of switches to configure the plurality of stator windings in the second configuration based on the condition of the power tool.
