“…Fig. 2.a and 2.c show the wheel tread (rolling surface) with clearly distinguishable lighter surfaces with metal glitter from the corroded surfaces, [10,11]. The difference among the conditions of these surfaces indicates that the crane doesn't use the whole width of the wheel tread.…”

“…Using the finite element method, Wu [24] and Zrnić et al [25] constructed multi-degree-of-freedom vibration models for crane structures to analyze the effects of the length of wire rope, the damping ratio, and the tilt angle of the sling load on the structural vibration. Other studies on crane vibration have focused mainly on the structural fatigue [13,[26][27][28] and dynamic properties [29,30] of cranes.…”

The operators of overhead traveling cranes experience discomfort as a result of the vibrations of crane structures. These vibrations are produced by defects in the rails on which the cranes move. To improve the comfort of operators, a nine-degree-of-freedom (nine-DOF) mathematical model of a “human–crane–rail” system was constructed. Based on the theoretical guidance provided in ISO 2631-1, an annoyance rate model was established, and quantization results were determined. A dynamic optimization design method for overhead traveling cranes is proposed. A particle swarm optimization (PSO) algorithm was used to optimize the crane structural design, with the structure parameters as the basic variables, the annoyance rate model as the objective function, and the acceleration amplitude and displacement amplitude of the crane as the constraint conditions. The proposed model and method were used to optimize the design of a double-girder 100 t–28.5 m casting crane, and the optimal parameters are obtained. The results show that optimization decreases the human annoyance rate from 28.3% to 9.8% and the root mean square of the weighted acceleration of human vibration from 0.59 m/s2to 0.38 m/s2. These results demonstrate the effectiveness and practical applicability of the models and method proposed in this paper.

“…The crane track damage and the remaining life of workshop rail crossbeam during crane operation are introduced and the necessary measures is proposed in (Kulka J et al, 2015). Through the measurement of track geometric deviations and the determination of skew motion caused by eccentric load, the failure problem of 200t casting crane caused by the rail wear is discussed in (Kulka J et al, 2016). Veronika (Vašková V et al 2017) analyses the crane operation failure attributed to the deformation of the track caused by the insufficient rigidity of crane track girder.…”

For the safety problems caused by abnormal changes of stress-time history at fatigue risk points of casting crane metal structure due to the vertical impact effect of track defects, the forecast method of fatigue residual life of casting crane under track defect model is proposed. Guided by the kinematics and dynamics theory, the kinematic-dynamic model of dynamic load resulted from crane travelling on defective track including the highlow dislocation and horizontal gap is established. The influence of track defects on the vertical impact effect of operation crane is analyzed. Furthermore, combining with the collection of technological process and usage of casting crane, the characteristic parameters needed in the process of stress spectrum acquisition are determined. The allowable stress method combined with finite element simulation is used to get the fatigue risk cross-sections and points of crane metal structure and the first principal stress-time histories of dangerous points are obtained. The double parameter stress spectrum of dangerous points is extracted by rain flow technology. Based on fracture mechanics and damage tolerance design, the fatigue residual life of dangerous points is estimated by Paris formula. Taking the 100/40t-28.5m casting crane as an example, the feasibility of the above model and method is verified.
