Comprehensive Insights into Single Girder Gantry Cranes
Single girder gantry cranes are characterized by their simple yet robust design. They consist of a single main girder supported by two legs, which run on ground rails. This eliminates the need for an overhead runway system, making them ideal for open areas or where overhead structures are limited. Their compact design allows for easy maneuverability and efficient material handling in various spaces. Capacity varies significantly depending on the specific design and manufacturer, ranging from a few tons to over 30 tons in some cases. The span, or the horizontal distance between the legs, is also customizable to suit the application.
