This bridge beam or single girder supports a lifting mechanism or hoist that 'runs' on the bottom flange of the bridge beam. Runway Flange Width (in) Runway Beam Depth Minimum Catalog Number Wheel Diameter (in) Max. If another manufacturers trolley is used and the wheel geometry is different, the girder may not react the same even though the capacity of the trolleys is the same. Single girder crane (SG): An overhead traveling crane that utilizes a single bridge beam attached to the two runway/end trucks. 21 Girders Selection for Single Girder Cranes. I work for an industrial crane manufacturer and we have pre-calculated girders, but they only apply to our trolley designs.
CRANE RUNWAY BEAM SIZE CALCULATOR SOFTWARE
The crane runways themselves are calculated according to. Bridge crane load calculation for load input to other structural analysis software for building structural analysis 2. I am not trying to discourage you from using existing results, but rather pointing out the value in knowing where they came from. The vertical and the horizontal wheel load on a crane runway beam is calculated according to EC1-3. This could lead to a catastrophic failure. Of the beam, support spacing, etc and these need to be factored into your selection and a chart may not detail what assumptions were made in its development. The wheel load, position of the load relative to the edge The size of an acceptable beam is a function of
CRANE RUNWAY BEAM SIZE CALCULATOR MANUAL
TheseĪre manual methods and I think preferable to some genericĬhart. There is some informationĬoncerning local flange bending in crane girders. A Beam the size of U/B762x267 (173kg/m) would be capable of taking the load you require 10,000kg, taking into account the dynamic load of 125 for the electric hoist, and that the hoist trolly would be running at worst on the edge of the lower flange. Two publications which you might consult. In Britain we use BS853:1957 to calculate the design of Runway Beams. I am not aware of any online chart per se but there are
