Kalmar unveils new auto selfloader

The so-called one-over-one Autoshuttle is claimed to be better than automatic guided vehicles (AGVs) as it can allow for the “decoupling” of ship and yard operations, reduce traffic congestion, optimise the space behind a STS crane, provide higher buffer capacity in front of yard stacks, and eliminate the need for a second STS trolley due to the buffer zone created on the quay. Only two to three of these units are needed to serve one STS crane, compared with five to seven AGVs. Each unit is capable of handling 20ft and 40ft containers, as well as two 20ft boxes in twin lift operation with load ratings of 40t (single) and 50t (twin). An onboard automation system controls the unit according to the routes specified by the terminal logistic system. The automated vehicle then continuously measures the distance and direction travelled with “odometric” information like wheel revolutions and steering angles. The unit’s position is formulated by passive, maintenance-free magnetic markers embedded in the terminal surface and magnetic measurement sensors located on the unit’s side frames. Fine positioning of the spreader is achieved by intelligent sensor technology installed on the spreader. The unit can also be remotely controlled when required.

Auto-shuttle parameters:

Capacity 50t (twin)/40t (single)
Max driving speed 30km/h
Max hoisting speed 20m/min – 13m/min
Min turn radius 9000mm
