RTG has a moveable crane on its top. RTG,rubber tyred gantry cranes are especially used equipemt at thecontainer yards for handling the normal 20 and 40 feet containers. Thesecranes are used almost all over the world at different largestcontainer terminals for performing this specific job of handling themillions of containers annually. RTGs serve inmost econoimical manner for straddiling of multi lane containers atrail or a road yard to get the maximum sorage density.
One example of well designed and successfully used RTG cranesis Konecranes which has been innovated very intelligently by itsdesigners. The machine employs the components which have proven theirperformance and require the least amount of maintenance with utmostdependability. These cranes provide the performance consistent to thecustomers’ expectations.
Konecranes RTG cranes have many additionalfeatures over and above the standard specifications of these gantrycranes. These additioanl features add to the performance substantiallyand help to considerably reduce the maintenance costs and down time ofthis equipemtn
- The crane has its exclusively designed sway prevention system thatprevents the sway of spreader rather than only dampening the sway.
- The spreader has a horizontal fine positioning that enables tomove it 300 mm without movement of trolley in the direction of trolleymovement.
- Spreader trim along with its hoist mechanisam eliminates the need of an additional trim mechanism.
- This gantry crane has sixteen wheels and reduces the cost of civilworks in container yards by causing minimum damages in the area ofoperation.
- Gantry drive is direct and there is no chain or wheels withsprokets. This feature imparts smooth movement to gantry and even themaintancne is lowest.
- 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.
