: For estimating the overall height for a standard 4.0m HUB
G-Rail™ bridge crane that has a 7.0 m bridge span
and 6.0 m runway span.
For C250 bridge crane rail, 7.0m Bridge span, “HB” is 1020mm
For C250 bridge crane rail, 6.0m Runway span, “HR” is 805mm
Overall Bridge Crane Height = 4000mm + 1020mm = 5020mm or 5.02m
Maximum loaded bridge crane
rail overhangs can be increased in many cases, but only after approval from the engineers
at Givens Engineering. Maximum bridge span of 9m can also be increased in some cases, with engineering approval.
