The South African Institute Of Materials Handling

SAIMH

The South African Institute of Materials Handling (SAIMH) is a Non-Profit organisation set up with an objective to encourage the transfer of knowledge associated within the fields of Bulk Materials Handling (conveyors, stacker, reclaimers, tipplers, train loading systems, etc.) through a combination of seminars and networking sessions. The SAIMH is made up of professional engineers, each practising their trade in a variety of organisations who volunteer their time to execute the SAIMH’s objective. The main aim is thus to promote the advancement of the art, science, theory and practice of the Bulk Materials Handling principles and techniques.

For the SAIMH and the industry as a whole to prosper requires the support of companies such as yours and key individuals from within your organisation who share the same passion and vision within the Bulk Materials Handling industry. The advantages of being a corporate member of the Institute are as follows: • To make the industry aware of the professional standards that our members provide, • To encourage the interchange amongst members of the institute of knowledge, experience relating to all aspects of the bulk materials handling, • To promote education, training to all levels of employees within the industry, To introduce and encourage the utilisation of leading world class material handling methods and techniques, • To be able to transfer and obtain additional knowledge at the bi-monthly joint Forum lectures, • To be able to communicate through the monthly official journal (which is sent to member free of charge).

These are just a few of the advantages that you will benefit from by being a corporate member. Just give us a few minutes of your valuable time and view our website, www.saimh.co.za, or email us on saimh@global.co.za and we will assist with your enquiry.
