Rubber-tyred gantry (RTG) cranes are the most popular equipment choice for container stacking at terminals around the world, especially where high-capacity stacking and good manoeuvrability are key requirements. How far you take automation will depend on your application requirements, and at Kalmar we give you the freedom to choose the mix that’s right for you, from fully manual to semi-automated or highly automated. Kalmar RTGs are the most efficient on the market in terms of both performance and energy consumption. We offer traditional, hybrid and electric models, as well as horizontal transportation with the Kalmar Terminal Tractors.

RTGs combine high stacking density with excellent manoeuvrability, making them a great fit for both medium-sized and larger terminals. The flexibility of RTG operation comes from the capability to change the operating stack, and with the safe Kalmar AutoRTG sideframe design, this can be done safer than ever. Safety is our first design principle in all automated solutions, and with modern technology, high level of automation is also available wirelessly.
Kalmar’s automation system Kalmar One enables job management and routing for RTGs. The onboard system guides the crane to its next position, either in semi-automated mode with the driver manually feeding in commands or automatically when interface to TOS has been set up. Safety can be further improved with 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).
