Optimal motion planning for overhead cranes [PDF]
Overhead cranes are widely used in industrial applications for material displacing. Many linear or non‐linear control schemes have been proposed for overhead cranes and implemented on electronic systems, but energy efficiency of transportation has seldom been considered in motion planning.

The Unsung Hero Towards Net Zero: The Role of Community Engagement in Circular Economy Capabilities
Abstract Prior circular economy (CE) literature has predominantly focused on technological knowledge in the development of firms’ CE capabilities. However, since CE represents a sustainable way of life that intricately links materials, technology and affected communities, technological knowledge alone is only partially useful.

Straddle carrier routing optimization at container terminals utilizing telemetry‐based prediction
Abstract Efficient vehicle routing and scheduling for horizontal transport means on container terminals can reduce lead times and travel distances, resulting in fuel savings and productivity gains. We apply machine learning to emulate operational processes, bridging the gap between theoretical optimization models and real‐world practices at container ...

Computational Model for Calculation Horizontal Forces on Crane Runway [PDF]
During a motion of an overhead bridge crane horizontal forces between wheels of the crane and the crane runway occur. These forces can be caused by skewing, acceleration or braking of the crane.

Failure of two overhead crane shafts
The failure analysis of two overhead crane shafts is presented: the failure of an overhead crane drive shaft and the failure of an overhead crane gearbox shaft, due to rotating-bending fatigue. The fracture of the overhead crane drive shaft originated in small radius fillet between two different diameters of the shaft.
