Today, Shandong crane manufacturers will share with you what precautions should be taken for the safe use of gantry cranes.

Portal crane is a variant of bridge crane, also known as gantry crane. Its metal structure is like a portal frame, with two legs installed under the main beam, which can walk directly on the ground track. The two ends of the main beam can have outward overhanging cantilever beams, mainly used for loading and unloading operations of outdoor cargo yards, material yards, and bulk cargo.

In work, there should be a certain amount of space between the external dimensions of the gantry crane and the cargo and transportation vehicle channels in the yard to facilitate loading and unloading operations. When general transport vehicles are loaded and unloaded within the span, they should maintain a distance of at least 0.7m from the door legs. When the lifting device is not working, there should be a distance of at least 0.5m between it and the transport vehicle. When the goods pass through the door legs, there should be a distance of at least 0.5m.

Portal cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port cargo yards.
