X_LT = 0.84 Weight of Crab Girders excluding Crab( Tons) = 20 Factored Logitudinal Force (KN) = 12.15 This distance is the minimum hook approach distance obtained from the manufacturer’s literature. ISMC Section Class is : Plastic Actual Deflection (mm) = 8.3 Shape Factor Z_Z = 1.1 In case the top flange of the girder is laterally supported then the section is checked for the moment capacity of the entire section. Design Of Gantry Girder As Per IS 800 2007. The weight of the crab and the lift load is shared by the two gantry girders inversely proportional to the distances of the crab from the girders. In the usual situations the span of the gantry girder is considerably large compared with the wheel base distance. The rails over the gantry girder are firmly fixed to the girder by bolted clamps or hook at a spacing of 0.50 m to 1 m to prevent the rail from lateral dislocation due to lateral forces. The rail provided over the gantry girder is assumed to offer no assistance to the gantry girder in supporting the wheel loads. A gantry girder is the piece of a crane that contains the equipment allowing the crane to roll over during its operation. Crane Girder Design to BS 5950-1:2000 Features: File: ReadmeCRANEgirder20041110.doc Page 1/1 Crane Girder Design to BS 5950-1:2000 CRANEgirder is an Excel Contact Us 108 nos. GANTRY GIRDER WordPress com. In the case of quick acting cranes stresses in the gantry girder are introduced almost instantaneously while in hand operated cranes, which are slow moving cranes stresses are introduced gradually. A section consisting of an I-section with a channel section attached to the top flange is proposed. For the case of the girder whose top flange is laterally unsupported the design bending strength is determined as-, where, Mz = Total vertical factored moment, Myƒ = Maximum horizontal moment (resisted by top flange only), Mdz = Design bending strength about z-z – axis. Design by allowable stress method as per IS 800 1984. Indian national code IS:800 for the design of steel structures was revised in the year 2007 incorporating limit state method.
