SUMMARY

The discussion focuses on selecting the appropriate IPE profile for jib cranes in the crane production industry. Key considerations include calculating deflections and identifying problematic stresses in the IPE profile. The standard yield strength (Sy) of RS37 grade steel is crucial for comparison during the selection process. Understanding these engineering principles is essential for making informed decisions in crane design.

PREREQUISITES
  • Understanding of IPE profiles and their applications in crane design
  • Knowledge of deflection calculations in structural engineering
  • Familiarity with yield strength concepts, specifically RS37 grade steel
  • Basic principles of stress analysis in engineering
NEXT STEPS
  • Research the calculation methods for deflections in structural beams
  • Study stress analysis techniques specific to IPE profiles
  • Learn about the mechanical properties of RS37 grade steel
  • Explore design guidelines for jib cranes and their structural requirements
USEFUL FOR

Engineers in the crane production industry, structural designers, and anyone involved in selecting steel profiles for construction projects.

So,I started to work in crane production industry . I suppose to choise the correct IPE profile for my jib crane (which looks like this one http://www.eotcranes.org/wp-content/uploads/2015/05/Post-Mounted-Jib-Crane.jpg ) , but no one in engineering department wants to explain me how to choose correctly (they all extra busy :( ) .
First of all , I see that they calculate deflections ,which I don't get why ? Why deflections are a factor ?

But anyway,my main question is how I choose the correct profile in my crane ? Ok,I suppose to find the most "problematic" stresses . How do I find them in IPE profile ? And then , I compare them to standart Sy of steel (RS37 grade) ?

Your questions cannot be answered in a few brief postings .

You'll need to learn the principles of engineering in depth before you can really understand and solve even a very simple problem like this one effectively and safely .
