RTGs combine high stacking density with excellent manoeuvrability, making them a great fit for both medium-sized and larger terminals. Although RTGs are usually fed by terminal tractors, it is also possible to use the Kalmar AutoShuttle for horizontal transportation between the quay and the stack. By automating horizontal transportation, you can make operations safer by removing the need for people to be in the handling lane under the crane.
Although automation is more straightforward at greenfield terminals, it is possible to convert existing – or brownfield – terminals to partial or full automation.
Kalmar’s equipment control system TLS enables automated positioning for RTGs. The system guides the hoist to its next position, with the driver manually feeding in commands in semi-automated mode. Safety can be further improved with automated gantry steering, anti-truck lifting (which prevents a locked chassis from being accidentally lifted), and stack profiling (which eliminates the risk of containers being accidentally knocked off the stack).
All Kalmar RTG models have an industry-leading maintenance interval of 1,000 hours for both crane and engine.
