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

    I'm no expert on high rise

    I'm no expert on high rise but it would be worth speaking to the crane hirer and manufacturer.To get a good balance, I would speak to manufacturers of similiar capacity machines too.Let me know how you get on

    My other question would be

     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

    The best tool to use is a

    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
