Advantages of a single girder design:

• Less expensive due to a simpler trolley design, reduced freight costs, simplified and faster installation, and less material for the bridge and runway beams
• Most economical option for light to medium-duty cranes
• Lower loads on the building structure or foundations due to a reduced deadweight. In many cases, it can be supported by existing roof structure without the use of additional support columns.
• Better hook approach for both trolley travel and bridge travel
• Easier to install, service, and maintain
• Ideal for workshops, warehouses, material yards, and manufacturing and production facilities
• Lighter load on runway rails or beams means less wear on the beams and end truck wheels over time
• Great for facilities with low headroom
