(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?
(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.
Hi All
I am currently working on tendering for a job which will use a 160T crane. My problem is ( New to the tendering game) i am struggling to work out what the hook time is and if we require 2 cranes for the duration of the job, Production percentages etc
Is there a excel spreadsheet or any examples that somone could help me with? How would i work out the hook time etc

The best tool to use is a Multi-Activity Chart to work out key cycle times then its a process of extrapolating the cycle times to various quantities and looking at alternatives (eg, using a pump instead of a crane for lifting concrete). Multi-Activity Charts are described at: https://www.mosaicprojects.com.au/WhitePapers/WP1025_Multi-Activity_Charts.pdf
My other question would be is there a basic formula to work out the number of lifts required per day from the tonnage of steel in each wall/base.
I seen something on another thread for tower cranes tha had an example:
Maerial Type Volume Container Capacity Hooks Programme Tasks Hour per day work day hook per day
Rebar in slab 69T Sling 1.2 58 5 12 3 4
I was wondering what the work day value was and how that relates to hook per day
