First, please park your truck in the designated parking area. Then, cross the street to reach the office. Inside the office, you'll need to use a computer to register your operation. Once you've completed the registration, you'll receive a printout with a barcode on it.
Next, drive to the gate and use the barcode to open it. After entering the gate, wait for further instructions from the crane operator. They will guide you to either stop 1 or stop 2, depending on whether you need to drop off or pick up your container.
