Advantages of a single girder
design:
1)Less
expensive due to a simpler trolley design, reduced freight costs, simplified and
faster installation, and less material for the
bridge
and runway beams.
2)Most
economical option for light to medium-duty cranes
3)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.
4)Better
hook approach for both trolley travel and bridge travel
5)Easier
to install, service, and maintain
6)Ideal
for workshops, warehouses, material yards, and manufacturing and production
facilities
7)Lighter
load on runway rails or beams means less wear on the beams and end truck wheels
over time
8)Great
for facilities with low headroom
