It is understood that there are two types of gantry cranes: single main beam type and double beam gantry type. When applying, first select a suitable type according to the actual situation to meet the lifting requirements. Only then can the safety distance be set on this basis to ensure the safety and stability during the operation. What principles should be observed when setting the safe operating distance of the gantry crane?
In order to meet the stability requirements of the mast along the direction of the crane track, first determine the wheelbase of the crane, basically based on the principle that the overall size of the cargo can smoothly pass through the flat steel frame of the outriggers. At the same time, there should be a certain space size between the external dimensions of the gantry crane and the cargo and transportation vehicle passages of the yard to facilitate loading and unloading operations.
When the vehicle is loaded and unloaded within the span, it should maintain a distance of more than 0.7m from the door legs of the crane; the spreader should maintain a distance of more than 0.5m from the vehicle when it is not in operation; when the goods pass through the door legs, there should be a distance of more than 0.5m. We must keep these three data in mind.
