Rubber Tyred Gantry Cranes for Container Terminals

RTG, the rubber tyred cranes are mobile cranes employed for lifting, moving and for staking the standard containers in stacking terminals in the specified staking areas. These cranes serve to stake many rows of containers in these container yards for rail or road, for achieving the maximum sorage density because of limited space in container terminals

Normally, a container loading crane moves on rails rather than rubber tyres. A RTG and a straddle carrrier are almost similar in appearance when viewed from the side. RTG has a moveable crane on its top. RTG, rubber tyred gantry cranes are especially used equipemt at the container yards for handling the normal 20 and 40 feet containers. These cranes are used almost all over the world at different largest container terminals for performing this specific job of handling the millions of containers annually. RTGs serve in most econoimical manner for straddiling of multi lane containers at rail or a road yard to get the maximum sorage density.

One example of well designed and successfully used RTG cranes is Konecranes which has been innovated very intelligently by its designers. The machine employs the components which have proven their performance and require the least amount of maintenance with utmost dependability. These cranes provide the performance consistent to the customers’ expectations.

Konecranes RTG cranes have many additional features over and above the standard specifications of these gantry cranes. These additioanl features add to the performance substantially and help to considerably reduce the maintenance costs and down time of this equipemtn

The additional features are as follows:

1. The crane has its exclusively designed sway prevention system that prevents the sway of spreader rather than only dampening the sway.
2. The spreader has a horizontal fine positioning that enables to move it 300 mm without movement of trolley in the direction of trolley movement.
3. Spreader trim along with its hoist mechanisam eliminates the need of an additional trim mechanism.
4. This gantry crane has sixteen wheels and reduces the cost of civil works in container yards by causing minimum damages in the area of operation.
5. Gantry drive is direct and there is no chain or wheels with sprokets. This feature imparts smooth movement to gantry and even the maintancne is lowest.
6. It does not have any hydraulic mechanism for even wheel steering or for micromotion of antisway spreader. These RTG machine mostly work in marine environment, they perform most reliably owing to this feature with least maintenance cost.
