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 hand tool for driving a fastener is provided. The hand tool includes gearing that interconnects a splined socket to a rotatable or trigger actuator and increases a rotational speed of the splined socket relative to the actuator. The hand tool may include a power tool receiver 38 or an independent motor to drive rotation of the splined socket to advance or retract a fastener from a threaded shaft. By increasing the speed and conserving rotational inertia, the hand tool reduces the time to secure a fastener on a threaded shaft. A rotatable nut is provided. The rotatable nut can slideably orient along a first axis and threadedly orient along a second axis to fasten to an adjacent surface.

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 wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: A reciprocating saw (10) includes a housing (14) defining a motor housing portion (18), and a motor (22) positioned in the motor housing portion (18), the motor (22) having a motor output shaft (26) defining a rotational axis (30, 89), and a motor activation switch (50) within the motor housing portion (18) and adjacent the motor (22). The reciprocating saw (10) also includes a transmission (54) is positioned downstream of the motor (22) and has a sawbar (58) connectable to a saw blade (62). The transmission (54) converts a rotational input provided by the motor (22) shaft to a reciprocating output of the sawbar (58) along a reciprocating axis (86) that is either coaxial or parallel with the rotational axis (30, 89).

Abstract: A handheld punch tool includes a housing defining a first axis, a motor contained within the housing, the motor having a motor shaft defining a second axis, and a head coupled to the housing and rotatable relative to the housing about a third axis. The head includes a drive member reciprocable along the third axis in response to rotation of the motor shaft about the second axis and a punch coupled to the drive member and reciprocable along a fourth axis in response to reciprocation of the drive member along the third axis. The third axis is perpendicular to the first axis, and the fourth axis is parallel to the third axis such that rotation of the head about the third axis varies a position of the punch relative to the housing.
