The controller should be arranged so that the driver can operate any two mechanisms at the same time.
Electrical equipment installed in the control room shall have no exposed points, and rain shield for electrical equipment installed on the trolley and the platform. Installation chassis of electrical equipment must be firm, its verticality is not more than 12/1000. The equipment should keep more than 500 mm channels as far as possible.
When the resistance box is superposed, it must not exceed the same frame. Otherwise, it should be fixed by another support, and corresponding heat dissipation measures should be taken. Resistor leads should be fixed.
Negative pipes for threading shall remove rust stains and burrs on the inner wall and be coated with anti-rust paint. The bending radius of the tube should be greater than five times its diameter (both ends of the tube are not limited). When installing pipes in a manufacturer, the nozzle shall be sealed and the pipe number shall be written according to the drawing when leaving the factory. The threading pipe is only allowed to saw and cut joints, the wire in the pipe is not allowed to have joints, and the nozzle of the pipe should be protected by a protective nozzle. Pipe and groove are fixed on the metal structure, but shall not be welded through. Pipe orifice position line groove should be able to prevent rainwater from entering directly.
Single sliding wire fixer, conductor and so on should be able to withstand AC voltage of 2,000 volts and one minute withstand voltage test.
All electrical equipment shall be reliably grounded without live housing or bracket. If grounding with installation bolts, good contact between bolts should be ensured. There should be reliable electrical connection between trolley and gantry, crane and crane track (the core of trolley power supply cable can be used as grounding wire to connect big and small trolley).
