wall jib crane

[attarther]

Hi
I have to design wall jib crane 5 Tonn arm 10 m and 8 m I use WF 500x300x11x15. I checked the stress, it's OK. but the deflection is to large about 120 mm. I dont have the relevant standard to be compare and I not sure that I can use L/150 for this case.
Pls give some standard such as CMAA, BS or FEM rule

You should be using relevant crane standards for this type of design work! If you don't have them, purchase them.
