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: Bi-directional motor (36) for gas engine replacement device (10). One embodiment provides a gas engine replacement device (10) including a housing (14), a battery receptacle (54), a motor (36), a power take-off shaft (38) receiving torque from the motor (36), a power switching network (310) configured to selectively provide power to the motor (36), and an electronic processor (302) coupled to the power switching network (310). The electronic processor (302) is configured to rotate the motor (36) in a first direction and receive an input to switch a rotation direction of the motor (36). The electronic processor is also configured to control the power switching network (310) to stop the motor (36) and rotate the motor (36) in a second direction after controlling the power switching network (310) to stop the motor (36).
