#CMT# #/CMT# The truck (1) has an automatic steering mechanism comprising two driving carriers (3) provided with guidable wheels for driving over a containerstack. A laser scanner (2) i.e. two dimensional laser scanner, measures a distance to a container wall from different angles, and supplies a measuring signal to an electronic controller. The laser scanner is arranged in the carrier, where the truck brakes automatically falls below a minimum distance to the wall. The controller computes a steering angle reference value for an electronically controlled vehicle steering mechanism. #CMT#USE : #/CMT# Portal stacker truck i.e. straddle carrier, for transporting and stacking of cargo containers, in a seas port. #CMT#ADVANTAGE : #/CMT# The design of the truck orients itself directly at the containerstack, reduces the burden of a driver from concentrated and fatigue steering, and offers collision protection, thus avoiding a large expenditure of complete navigation system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows perspective view of a portal stacker truck when traversing a container stack, and a laser scanner attached at a front left driving carrier in a ramming buffer. 1 : Portal stacker truck 2 : Laser scanner 3 : Driving carriers 4 : Cargo container. |
