The tandem headblock, SingFlex®, is capable of handling multiple containers in a single hoist lifting operation and is electro-hydraulically operated with all functions of the headblock controlled from the crane operator’s cabin.
SingFlex can be retrofitted to most container handling cranes by ISO floating twistlocks connecting the tandem headblock to the spreaders.
Quick change over between single spreader to twin spreader is fully automated and is done within 2 minutes without assistance from support staff. The switch over takes place in the headblock's very own docking station.
