UNIT WEIGHT OF CRANE RAILS

Dear Readers, Wish You a Happy Diwali - 2012

Crane rail shall be designated by the letters ISCR followed by the head width of the rail section.  For shop marking and drawing office purpose abbreviated reference symbol CR instead of ISCR may be used. It is designated as per Indian Standard IS:3443

 

It shall have a minimum tensile strength of 710MPa (72kgf /sq mm) and Unit weight shall be measured by Kg/meter. Some other non metric standard rails are available in market. It shall designated based on the weights per meter. Dimensions, Other properties and unit weight of non metric standards will  be followed my next post.  

 

Unit weight of standard Crane rails are as follows.

Torque for HT / HSFG Bolts

Dear Readers,Wish You a Happy Durga Pooja.

 

Based on my previous posts you may familiar with grades of bolt, torque of bolt, torque calculations and slip factors. However it is a real challenge in construction industry to determine the torque for bolts. Technically it is based on the applications. Some times client mentioned in drawings or you may get it from technical specifications but most of the times both are missed out. Given below is an ideal chart. This is one of my rare collections. Hope it will be very useful to all engineers.

Properties of ISJB

Dear Readers,

This is continuation with my earlier post "Unit Weight of ISJB", self would like to post the sectional properties of ISJB. This will be good alternate for ISMB and ISLB.

Properties of beams are having two parts. One part is Physical dimensions and another part is sectional properties of ISJB. Basically dimensional part contains depth and width of section, Thickness of Web and Flange and Root Radius. Where as sectional properties contains Moment of Inertia, Radius of Gyration and Section Modulus. These are useful for design engineers.
