Welcome to The ME2045 Group J Crane Project Blog page!


This entire site is to give a guide to Group J`s efforts to design a small portable crane for use in disaster relief before our final submission of work and our presentation.

Following our first meeting (See the Minute Meetings Topic for reference) the following positions have been allocated;

D.Scriven Project Manager
R.Sidhu Chief Designer
H.Singh Sall Finnance Officer
J.Sidhu Materials Specialist
R.Shukla Stress Analysis

For Our Progress up to date please see the Project Plan below and then head to the relevant topic and we hope you find our work interesting!

Forces/Stress Calculation (i)













To find the counter balancing weight required for the crane beam to lift 1500kg and the total force going through to the boom, we use moments -

Equate the clockwise and anticlockwise moments:

(About C clockwise) - Xg x 1 = 55.2g x (1.5 - 1) + 1000g x 2

Xg = 27.6g + 2000g = 2027.6Kg mass required for balance

2027.6 x 9.8 = 19870.48N force required for balance

Equating the forces in a vertical direction:

R = Xg + 55.2g + 1000g = 2027.6g + 55.2g + 1000g = 3082.8Kg Mass

4582.8 x 9.8 = 30211.44N Force - Both of which is the total amount acting through to the boom.
