Draglines are used extensively for removal of overburden in the coal mining industry. Draglines with tubular booms are among the structures most susceptible to fatigue cracking due to the large number of high load cycles to which they are subjected d

‘Hot spot stress’ is an approach often used to consider fatigue loadings in heavily welded tubular joints. This article reports the determination of hot spot stresses in mining dragline booms, which are often ≥100 m in length, using strain gage

Mining dragline joints are observed to develop fatigue induced cracks in operation in field, which are further compounded by the effects of weld-generated residual stresses. A typical dragline used in the Australian coal mining industry is fabricated

Failures in hoist and drag ropes are studied and described based on site inspections on Marion and BE draglines. Causes of the failures are discussed. Some of the analyses of the wire rope failures centres on the wire rope accessories through which t
