1. A hoist device, comprising:
a power source;
a motor having an output shaft;
a transmission coupled to the output shaft and configured to interface with a workpiece;
a controller configured to wirelessly communicate with a wireless transceiver of the hoist device, the controller configured to:
control an operation of the motor,
determine a magnitude of a load associated with the workpiece; and
control a rate of acceleration of the motor based on the determined magnitude, and
a load detection device in communication with the controller, wherein the load detection device is a hydraulic cylinder coupled between the hoist device and a hoist support point, the hydraulic cylinder including a pressure sensor in communication with the controller,
wherein the rate of acceleration is reduced in response to an increase in the magnitude of the load, and
wherein the hoist device is configured to raise and lower the workpiece based on a user command signal received at the controller.
