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.

Wireless hoist system

A method for expanding features of a gas engine replacement device that drives power equipment including controlling, by an electronic processor of the gas engine replacement device, a power switching network to selectively provide power from a battery pack to rotate a motor of the gas engine replacement device. A module interface of the gas engine replacement device receives an external electronics module. A type of the external electronics module received by the module interface is detected by the electronic processor of the gas engine replacement device. The gas engine replacement device is configured by the electronic processor based on the type of the received external electronics module. The electronic processor communicates with the external electronics module via the module interface.

Bi-directional motor for gas engine replacement device

A concrete vibrator includes a frame, a strap coupled to the frame, a main housing supported upon the frame, and an electric motor coupled to the main housing. The concrete vibrator further comprises a flexible shaft having a first end coupled to the motor and an opposite, second end. The concrete vibrator further comprises a vibrator head coupled to the second end of the shaft, the vibrator head configured to receive torque from the motor and the shaft to cause the vibrator head to vibrate. The concrete vibrator is operable in a backpack configuration in which the strap is used to carry the concrete vibrator with the frame in a vertical orientation, and in a briefcase configuration in which the frame is supportable in a horizontal orientation.

Concrete vibrator for use in backpack and stationary configurations

A concrete vibrator includes a housing, a handle, an electric motor, a flexible shaft, a vibrator head, and a battery pack. The handle extends from the housing. The electric motor is coupled to the housing. The flexible shaft has a first end coupled to the motor and an opposite, second end. The vibrator head is coupled to the second end of the shaft. The vibrator head is configured to receive torque from the motor and the shaft to cause the vibrator head to vibrate. The battery pack is coupled to a battery receptacle defined on the housing. The battery pack is configured to provide electric power to the electric motor to drive the motor and the shaft. The concrete vibrator is operable in a briefcase configuration in which the handle is used to carry the concrete vibrator with the housing supported in a horizontal orientation.

A cut-off saw configured to remove material from a workpiece, the cut-off saw includes a motor, a blade, a drive assembly, a handle, and a coating. The blade is capable of removing material from the workpiece upon contact between the blade and the workpiece. The drive assembly is coupled to the motor and the blade and is configured to transmit torque from the motor to the blade. The handle is configured to be grasped by a user, and includes a surface and a first material having a first surface resistivity. The coating covers at least a portion of the handle. The coating is configured to distribute static electricity away from the surface. The coating is made of a second material having a second surface resistivity less than the first surface resistivity.

Static discharge mitigation of power tools

One embodiment provides an adapter for configuring device settings of a gas engine replacement device. The adapter includes a transceiver, a user interface, and an electronic processor. The electronic processor is configured to connect the adapter to the gas engine replacement device and generate a graphical user interface showing a plurality of configurable device settings. The electronic processor is also configured to receive user input to choose one or more device settings to configure and receive user input to configure the one or more device setting chosen and generate changed device settings. The electronic processor is also configured to transmit the changed device settings to the gas engine replacement device. The gas engine replacement device is then used to drive power equipment in accordance with the changed device settings.
