Abstract: A lifting device includes a base, a mast coupled to the base, a carriage coupled to the mast, and a lifting assembly configured to move the mast and carriage in a first direction to a desired elevation relative to the base. The lifting device includes an electric motor, a battery pack for providing electrical power to the electric motor and a spool with a cable to alternately raise and lower the carriage in the first direction. The lifting device includes means for detecting a weight and/or a center of gravity of a load to be lifted by the lifting device, and a user interface operable to communicate information about the weight and/or the center of gravity of the load to a user of the lifting device.

Abstract: A cable puller has a frame, a capstan rotatably mounted on the frame, a motor which drives the capstan to rotate, a power supply which supplies electrical current to the motor, a transmission which transfers torque from the motor to the capstan, a display mounted to the frame, a sensor operable to generate a signal, and a controller. The transmission can operate in a low-speed configuration and a high-speed configuration. The controller is electrically coupled to the motor, the power supply, and the display. The controller includes computer executable instructions stored in a computer readable medium for controlling operation of the cable puller to receive the signal from the sensor, determine a torque of the capstan based on the signal, determine a tension of a cable being pulled based on the torque of the capstan, and generate a control signal when the tension of the cable approaches a predetermined tension.

Abstract: A lifting device includes a base, a mast coupled to the base, a carriage coupled to the mast, and a lifting assembly configured to move the mast and carriage in a first direction to a desired elevation relative to the base. The lifting device also includes an electric motor, a battery pack for providing electrical power to the electric motor and a first spool with a first cable to alternately raise and lower the carriage in the first direction. The lifting device further includes an auxiliary drive unit including a second spool with a second cable to raise and lower the lifting device in a second direction different than the first direction.
