Abstract
A railway nipper machine is provided that includes a nipper frame having a pair of nipper hooks for performing a nipping operation, and a position feedback device having a central control module configured for controlling the nipping operation based on a depth signal and a time signal. Further included in the nipper machine is a depth sensor connected to the position feedback device for generating the depth signal relative to a nipper actuator connected to the nipper frame, wherein the depth sensor transmits the depth signal to the position feedback device. A timer is provided for generating the time signal, and the nipper machine is actuated by the nipper actuator in response to a determination value generated by the position feedback device based on the depth signal and the time signal.
