The step chain in the step system is responsible for transporting the passengers carried on the step pedals. The step chain is connected by step chain plates and pins. For the convenience of installation, the error of punching the escalator chain plates will be reduced as much as possible during the production of step chain plates. Therefore, when punching the escalator step chain plates, an escalator chain plate punching device is generally selected for the punching operation.
