Subject - Crane
Dear all

We are having a 200MT crawler crane with lattice boom at site. There was a 4 fall rope in the crane. Now they extended the boom with 2 fall rope. My doubt is

1. Whether the load chart is mentioning only boom capacity?
2. If yes then how to find rope capacity?

crane operator is telling that load chart value only for boom angle and it's capacity. Rope is 28mm. Don't know what kind of rope exactly and he is telling 14 MT capacity per fall.

Pls reply.

Hi,

I saw your post and, if the crane is ok, all papers in order.... it´s all just fine!
It´s not easy is not easy to put another steel cable on the crane, other than the original, and that crane is prepared to lift much more weight!
Is it a LIEBHERR?
More than a load diagram you shoul have a lifting plan... anyway it´s a 14t lift, even in the worst scenario, it´s ok!....
The load chart has everthing in consideration: cable and all components!!!
I work with all kind of cranes, up to 1000 t.
If you need email me your questions: patricia.lj.vieira@gmail.com

Hi, Do you know the crane model. All your questions about the crane's capaitires and limitations will be answered when you review the crane manual. When a crane configuration is modified it needs to be re-inspected and recertified fit-for-use, the number of part lines will be specified in the certificate - this will be a great help (if the certifying oranization is reliable - beware of "mickey mouse" certification companies). To revent this (risk) from occuring again, it is good to do a comlete Risk Assessment for the whole operation starting from crane selection.

Maybe I have some info about the crane. What Model is it (Liebherr, American / Manitowok, etc). Hace you reviewed the third party fit-for-use certification?

To be able to know exactly if the rope lay is proper and the rope ? wire if of the forrect kind, more information is needed. It may not be a good ideat to relyy 100% on the Crane Operator's remarks unless he is the designated competent person of the company.
