Technical and Operational benefits

In addition to the traditional RTG Crane specifications, our RTG Crane includes as standard several extra features which significantly increase the performance and reliability as well as decrease the maintenance cost of the cranes. Such features are for example:

• Unique sway prevention system that really prevents the sway of the spreader instead of only dampening the existing sway.
• Horizontal fine positioning of the spreader (the spreader can be moved up to 300 mm in trolley/gantry travel direction without moving the trolley/gantry).
• Spreader trim with hoist machinery units eliminating separate special trim mechanisms.
• Sixteen gantry wheels with low wheel loads making significant savings in civil works costs of the container yard possible.
• Direct gantry drive without any chains and sprocket wheels resulting in smooth and accurate gantry travel motion and minimum maintenance.
• Wheel turning with the crane travel machinery eliminating the maintenance intensive separate hydraulic mechanisms for wheel turning.
• No hydraulics on the crane, only on the spreader. This means better reliability and less maintenance

Very important feature of Konecranes RTG Crane is that the Crane does not have any hydraulic systems, not even for gantry wheel turning, anti-sway or spreader micro motions. Because the RTG Cranes are operating in harsh marine conditions, this is a very big advantage resulting in high reliability as well as low maintenance and spare parts cost.
