Large excavators such as the mining dragline (Figure 10.1a) and shovel (Figure 10.1b) are used for surface mining to dig and transport overburden [110]. Their large size front-end structures can swing either left or right during working. The repeated loading induces the front-end to undergo fatigue loading as a result of significant cracking at welded connections [10,11] and fatigue failure as simulated in Figure 10.2. It is estimated that 90% of structural failures in large excavators are due to fatigue alone. Several decades ago, the boom of Peabody Coal Company's Marion 8750 failed during operation at the Black Mesa Mine (www.miningmayhem.com). The boom failure was caused by the dynamic stress loading coming through the tight drag and hoist ropes. In recent years, seven large shovel and three walking draglines had experienced some boom or tri-structure lacing cracking not long after going into service, which resulted in the maintenance casts ranged between $20 and $130 million [112]. Therefore, it is important to ensure the excavator longevity and reduce the high capital investment. Researchers had tried to find efficient analysis technologies to monitor the overall stress loading of front-end structure to avoid fatigue failure

The University of Eastern Londons School of Architecture, Computing, and Engineering (ACE) uses the Shake Table II in a number of study areas, including the determination of natural frequencies in multi-DOF structures, and the seismic response of building frames. The Shake Table II provides students with valuable, hands-on experimental experience along with a better understanding of the theoretical concepts presented in ACEs Civil Engineering courses. For researchers, it means expanding their work in such areas as the seismic response of base-isolated structures and soil-structure interaction

The proper operation and the life of the gear reducer mainly depend on the proper lubrication of the moving parts. Lubrication oil of a suitable viscosity is contained in the bottom of the housing to provide an oil bath for the gears, which carry the oil upward as they turn. Oil brought to the top of the gears is taken off by wipers; excess oil is directed to oil channels that lead the lubricant to every bearing. This works only with sufficiently high pumping speeds above 5 SPM when enough oil is carried upward by the gears. At speeds less than 5 SPM, an additional wiper has to be added to the high-speed gear to ensure proper lubrication. Regular inspection and change of the oil is a prime requirement for trouble-free operation
