TOC Europe 2018 in Rotterdam played host to a talk by Cameron Hay on the trends in tandem lifting that show an increase in ports and terminals using single hoist tandem.
The talk began by making reference to published technical article by SIPG revealing some design and complexity issues with dual hoist operations and that dual hoist operations consume a high amount of energy, which as a result are not generally in high use. Also discussed was the fact that new terminals are not selecting dual hoist cranes, but instead opting for more economical single hoist dual spreader cranes.
The results of an independent review showed the Ship to Shore crane headblock for single hoist cranes, known as SingFlex was the most superior headblock. Cameron commented
“The industry is clearly moving toward higher TEU ratios and tandem 40 will be the norm. Terminals using SingFlex are achieving greater than 40% of all moves in tandem with its flexible design.”
