Introduction

I. INTRODUCTION

Electric overhead Travelling crane is a machine which is  lift, lower and move heavy material from one place to another in a precise manner in industry or construction sites. It is equipped with hoist mechanism contains motor, pulley, rope drum, coupling gear and motor shaft, etc. Electric overhead Travelling crane are widely used in many industries under safe working load. capacity of cranes depend on the types of crane and purpose of industry. Cranes are used in manufacturing industry, construction sites, transport industry for loading and unloading. Due to this random loading and unloading Crane hook, Rope, Rope Drum, Coupling, Gear and Motor Shaft failure occurs in EOT Crane. Various type of overhead cranes used in industry are single girder cranes, double girder crane, gantry crane and monorail, etc. Basic component of electric overhead crane are girder, end carriage, hoist, hoist cable, crane hook, rack and pinion mechanism, pulley, runway, runway rail, trolly, motor, etc.

It has high carbon steel. After investigation of wire rope the reason of failure occurs due to broke strands with dry damaged core and inner core strands nicking along its length. Insufficient lubrication provide to wire rope results in dry core. The fracture point of wire rope exhibited chisel shaped marks. This chisel shaped marks showed using SEM in Fractography. The assign bending fatigue consideration of rope diameter, sleave diameter, co-efficient of sleave shape, factor of safety, metallic area and working load would be check in the six month of span. Microstructural investigation also draw pearlite in the matrix. Irregular lubrication led to fretting wear between the internal wires.
