Kalmar launches its fully-automated Shuttle Carrier®

Kalmar launches its fully-automated Shuttle Carrier®

The one-over-one Autoshuttle™ boasts major benefits over its older rival, automatic guided vehicles (AGVs). Advantages include the decoupling of vessel and yard operations, reduction of traffic congestion, better space utilisation behind a STS crane, higher buffer capacity in front of yard stacks, and the elimination of a second STS trolley due to the buffer zone created on the quay.

According to the company, only two to three Autoshuttle™ units, compared to between five and seven AGVs, are needed to serve one STS crane, resulting in faster, more efficient terminal operations and offers the “ultimate productivity boost to terminal operations when combined with an automatic stacking crane system – also available from Kalmar.”

Like its manually operated counterpart, the Autoshuttle™ is capable of handling 20ft and 40ft containers, as well as two 20ft boxes in twin lift operation with load ratings of 40 tonnes (single) and 50 tonnes (twin). Engineered with 7th generation Kalmar straddle and shuttle carrier technology, the Autoshuttle™ also features an enhanced PLC diagnostics system.

The onboard automation system controls the Autoshuttle™ according to the routes specified by the Terminal Logistic System. The automated vehicle continuously measures the distance and direction travelled with odometric information like wheel revolutions and steering angles.

Navigation of the Autoshuttle™ is based on patented Magnetic Measurement System (MMS) technology. The unit’s position is formulated by the magnetic markers embedded in the terminal surface and MMS sensors located on the Kalmar Autoshuttle™’s side frames. The passive, maintenance-free magnetic markers are an affordable, controllable and reliable alternative compared to more complicated solutions such as transponders.

Fine positioning of the spreader is achieved by intelligent sensor technology installed on the spreader. The unit can also be remotely controlled when required.
