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 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 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 power tool having a housing, a motor, a tool holder driven about an output axis by the motor, and an output element for performing an operation on a workpiece. The tool holder has a locating feature including a tapered portion becoming narrower in a direction away from the surface of the tool holder. The output element has an aperture for receiving the locating feature and a face facing the surface of the tool holder when the locating feature is received. The power tool also includes a flange for transferring a clamping force for urging the output element towards the tool holder and a tab projecting from the flange for finger tightening the flange. A biasing member provides the clamping force toollessly. A gap is defined between the surface of the tool holder and the face when the tapered portion of the locating feature is fully received in the aperture.

Abstract: A stand-alone motor unit for use with a piece of power equipment includes a housing and a flange coupled to the housing on a first side thereof. A plurality of apertures through the flange defines a first bolt pattern that matches an identical, second bolt pattern defined in the piece of power equipment. An electric motor has a power output of at least about 2760 W. The motor includes a stator having a nominal outer diameter of up to about 80 mm and a rotor supported for rotation within the stator. A power take-off shaft receives torque from the rotor and protrudes from one of the flange or a second side of the housing. A controller is positioned within the housing and electrically connected to the motor. A battery pack for powering the motor has battery cells having a nominal voltage of up to about 80 V.

Abstract: A reciprocating saw includes a housing defining a motor housing portion, and a motor positioned in the motor housing portion, the motor having a motor output shaft defining a rotational axis, and a motor activation switch within the motor housing portion and adjacent the motor. The reciprocating saw also includes a transmission is positioned downstream of the motor and has a sawbar connectable to a saw blade. The transmission converts a rotational input provided by the motor shaft to a reciprocating output of the sawbar along a reciprocating axis that is either coaxial or parallel with the rotational axis.
