PLC Control RTG Rubber Tyre Gantry Crane For 40ft 45ft Container
Rubber Tyre Gantry Crane Introduction
The rubber tyre container gantry crane (refered to “RTG” as below) is used to offload, stack and load 20ft and 40ft containers. The crane contains three mechanisms: hoisting, trolley travelling and gantry travelling. The trolley running along the track which mounted on gantry beam is capable to serve among legs. The crane is able to make straight movement along rails.
Full hydraulic drive for crane traveling mechanism with Step less speed change. The long traveling use hydraulic closed circuit with good transmission efficiency, less fault. There are safety indicator and overlord limiter to ensure safety of operators and products. All operation are controlled by CAN-BUS control.
The crane is equipped with appropriate container spreader, which should be able to handle single unit 20ft and 40 ft containers；Or twin-lift container;
Hoisting mechanism and trolley travel are able to work simultaneously or separately with load; the same applies to gantry travel and trolley travel.
Electrical drive of main working mechanism equipped with full digital AC frequency convertor, PLC speed governor and constant power adjustment device for hoisting mechanism.
