摘要： A powered threaded rod cutter includes first and second cutting dies, an electric motor, a planetary transmission positioned downstream of the motor, a drivetrain for converting a rotational output of the transmission to a pivoting movement of the first cutting die, and a clutch mechanism for redirecting torque from the motor away from a drivetrain and the first cutting die in response to the first cutting die seizing during a rod-cutting operation. The clutch mechanism includes a ring gear in the planetary transmission, and a spring that rotationally affixes the ring gear below a predetermined threshold of reaction torque through the drivetrain and permits rotation of the ring gear above the threshold.

摘要： A core drill includes a housing, a first handle extending from the housing and defining a gap between the handle and the housing, a motor supported within the housing, and a battery removably coupled to the housing and configured to provide power to the motor. The battery has an output voltage greater than 40 volts. The core drill further includes a spindle configured to rotate about a rotational axis in response to torque received from the motor and a fluid delivery system configured to supply fluid to the spindle. The fluid delivery system includes a valve operable to regulate a flow of fluid to the spindle and an auxiliary handle removably coupleable to the housing at each of a first mounting point and a second mounting point.

摘要： A magnetic drill press includes a main housing, a drill unit supported by the main housing for relative movement therewith in a direction of a rotational axis of the drill unit, and a base coupled to the main housing for selectively magnetically latching to a ferromagnetic workpiece. The base includes a magnet holder, a fixed magnet assembly supported within the magnet holder, a rotatable magnet assembly supported within the magnet holder, and a transmission. The transmission includes an input, an output coupled to the rotatable magnet assembly for rotating the rotatable magnet assembly relative to the fixed magnet assembly through a predetermined rotation angle, and a gear train positioned between the output and the input. The gear train is configured to provide a variable gear ratio between the output and the input during at least a portion of the predetermined rotation angle.

摘要： 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.
