Since the ports are close to the sea or river, we must consider the waterproof of power plug-in, the international specificity of transportation tools such as containers, the mobility of some temporary loading and unloading equipment and the convenience of equipment maintenance power supply.

1 power supply for shipping containers

The power supply facilities of the port and wharf must be matched with the international shipping. In order to maintain the freezing temperature in the refrigerated container during transfer, it is necessary to plug in the power supply on the wharf to continue cooling. This determines that the storage yard must be equipped with sockets of the same specification as the container. That is, 380V 32A ground pole 3h, 4 pole, anti immersion industrial plug socket should be used.

2 power supply for Wharf mobile equipment

There are some loading and unloading equipment that often need to be moved on the wharf, so it is more convenient to use plug-in power supply for equipment movement and operation. For example, the buried scraper conveyor and its auxiliary facilities generally adopt the 6h immersion proof industrial plug socket.

3 maintenance of wharf equipment

The yard used for transferring and stacking goods at the wharf is usually large. There are various loading and unloading equipment, including large gantry crane, crane, conveyor, conveyor belt, etc. However, whether it is a large gantry crane or a long coal conveyor belt, sometimes it needs to be overhauled. For the convenience of maintenance, a power socket or power box shall be set beside the equipment. The electric welding machines and other equipment repaired in this way can be used immediately after they are plugged in. Similarly, the maintenance workshop also needs to be equipped with power sockets or socket boxes to make the equipment have power. The maintenance power box is generally equipped with a variety of 6h earth poles and splash proof industrial sockets.
