FOREWORD
This Indian Standard (Part 1)was adopted by theBureau ofIndian Standards, after the draft finalized by the
Continuous Bulk Conveying, Elevating, Hoisting, Aerial Ropeways and Related Equipment Sectional
Committee hadbeenapproved bytheMechanical Engineering Division Council.
Amusement parks in India are becoming quite common and people visit these parks quite often. In order to
