Single Girder Overhead Crane is a kind of light and small material handling equipment with reasonable structure and strong rigidity. It is used in factories, warehouses, stockyards, and other busy and heavy work situations.
The single girder overhead crane or single girder bridge crane consists of one girder beam supported on each side by an end truck. The trolley and hoist are most commonly underhung, which means they run on the bridge’s bottom flange. In terms of design, the bridge can be either top running or under running.
For many applications and industries, single girder bridge cranes are the most cost-effective lifting solution. Single girder cranes use less material and are more compact and lightweight than double overhead girder cranes, resulting in significant material, freight, and installation cost savings. Furthermore, because only one bridge beam is required, these systems typically have less dead weight, allowing them to use lighter runway systems and tie into the existing building support structure.
