Abstract
Immense pressure on environmental impact of yard machinery as part of operating system in container handling industry has led to the introduction of hybrid straddle carrier (HSC). This study attempted to examines operational activity of HSC to distinguish major factors that embroiled in high energy cost and develop appropriate method to measure it. The proposal includes combination of data logging system, spatial data acquisition and visual motion analysis. Motion based analysis was introduced to improve the accuracy of energy analysis, and impact of various motions on HSC performance is explained. Energy analysis from measurement result was able to show that height of stack has impact on battery state of charge during lowering and traveling motion covers 52% from total fuel consumption. Some counter measures are proposed to increase efficiency as well as exploit full potential of HSC.
