What protective measures should be taken for port cranes in high-temperature conditions?
Thread Content
As is well known, most port cranes operate outdoors at docks and ports. When exposed to high-temperature environments frequently, what protective measures should port cranes operating in such conditions take? 1. If port cranes are frequently exposed to the sun, protective measures must be taken for their electrical control equipment. At the same time, it is important to ensure that the protective measures are safe and reliable. If working with electronic devices, since it cannot be guaranteed that these devices will function properly, it is best to install air conditioning. 2. For the parts of port cranes that are frequently exposed to thermal radiation, such as wires and cables, the following measures need to be taken. It is necessary to use heat-resistant thermoelectric tubes made of mica for threading the wires, and a heat-resistant material must also be placed under the metal tube. 3. If a port crane operates indoors, and the electrical equipment mounted on its bridge deck has no exposed or live parts, its protection rating must be at the level specified in GB4942.2.
