HOW TO PULL THE HOIST ROPE OF GUY TYPE DERRICK CRANE MODERATELY AND IN AN INCLINED ANGLE WITH A DRAG ROPE

Jinrui Chen

Open publisher page 0 citations

Abstract

This paper briefly describes the structure and principle of the cable type derrick crane with a drag rope operating with the hoist rope for increasing the working range,The loads on its main components are analyzed and the formulas are obtained for determining their loads.The calculation and comparison indicates that pulling the hoist rope in an inclined angle within the permitted limits in operation is feasible and safe. The appropriate parameters for this kind of cranes are suggested for design.
