| Abstract: | In order to ensure the gantry crane reaching correct lift height, it is necessary to make a calculation of reset value. Taking FUJI gantry crane as an example, this paper introduces the working principle of the protection system. It analyzes the system from three aspects, such as judgement on infrared senser switch quantity, position limit by cam and logic calculation by PLC. Also it introduces the reset method. This method enhances the safety guarantee of the gantry. |
