Abstract: A motor lifting device may include a base member, a vertical guide column coupled and extending upward from the base member in a vertical direction, a carriage coupled to the vertical guide column. The carriage may including a carriage base engaged with and movable along the vertical guide column, and a carriage plate defining one or more slots configured to receive a motor shaft. The motor lifting device may further include one or more transverse actuators structurally configured to move the carriage plate in a direction transverse to the vertical direction with respect to the vertical guide column.

Abstract: A method for removing a fin fan motor from a heat exchanger includes positioning a motor lifting device beneath the fin fan motor, moving a carriage of the motor lifting device upward in a vertical direction with respect to a base member of the motor lifting device along a vertical guide column, moving one or more vertical support members into a locked position, the one or more vertical support members spaced apart from the vertical guide column and extending between the carriage and the base member, where the one or more vertical support members restrict vertical movement of the carriage with respect to the base member in the locked position, and moving the fin fan motor to the carriage of the motor lifting device.

Abstract: An assembly for separating a coupling hub from a shaft of a rotating machine includes a support frame sub-assembly that structurally supports the assembly and the coupling hub. A vertical adjustment sub-assembly is structurally supported by the support frame sub-assembly. The vertical adjustment sub-assembly adjusts the elevation of a puller sub-assembly from the surface of the Earth. The puller sub-assembly couples to the coupling hub and separates the coupling hub from the shaft.
