Quay crane system and operation process after upgrading and remodeling

摘要

In the quay crane system and operation process after upgrading and remodeling, the traditional quay crane girder is converted into two trapezoidal four-track girder (1), and the upper trolley ( 2) runs, and the low trolley (3) is hooked upside down on the outer low trolley running track (a8) on the 2 trapezoidal 4-track girder (1), while the upper trolley (2) holds the container (5) through the sling (4). Lift it so that it can pass through the low trolley (3). The quay crane system is based on one working trolley of the traditional quay crane, and one working trolley is added to the outside of the existing quay crane girder. , the two trolleys work independently, without interfering with each other; The two trolleys of the quay wall crane after the renovation intersect and pass spatially, overlapping in time, so that the unloading efficiency is doubled.
