Crane - Telescopic boom calculation
Crane - Telescopic boom calculation
(OP)
Hi All,
I've been asked to calculate the bending moments of a 4 stage telescopic boom. I've looked at the BS ISO standards for crane design but there's nothing about a telescopic crane. The crane has to pickup 500kg's using a grab at the max extension of 4m (horizontal).
Can someone please direct me to some relevant info (examples, standards, etc) please.
Regards
Muon.

I spoke to a stress engineer today, and he's given me a rough idea how to tackle the problem. I was having trouble of how to work out the bending moments on the sliding joints (were the stages overlap). It seems that the stages can be modeled as lever arms. All I need to do now is work out if the stainless steel rectangular hollow sections (the stages) will take the 500kg load.
