Side Arm Charger

Side arm charger is a marshalling device to position the loaded wagon on tippler platform one by one for unloading operation by tippler. Operation: the full rake of 58 wagons shall be brought in by locomotive and stopped with the leading wagon within range of the side arm charger. The locomotive is then taken away. The charger shall be driven to the leading wagon, its arm is lowered and it is coupled to the first wagon of the rake. The charger then hauls the rake forward until the front of second wagon is about one wagon length away from the tippler platform. The charger then stops and the first wagon is decoupled from the rake manually. The charger then propels the leading wagon on to the tippler, and then automatically decouples and clears off the tippler. Now the wagon tippler is ready for operation. In the meanwhile, the side arm charger is moved back to initial position for next cycle. In next cycle, the rake is drawn up by the wagon length, and the previously tippled wagon is ejected simultaneously. After tippling of the last wagon, the charger is used under manual control to eject the last wagon from the tippler, if the next wagon is not already in position. Special features: hydraulically operated for movement and arm hoisting/lowering; brake integral with hydraulic motor; robust and reliable; and suitable for continuous duty. Main components: hydraulic power pack, electric supply system, supports, rack and pinion, buffer stop, etc. The side arm charger is mounted along side the main rail track and is run on its rail track parallel to the main track. The pulling capacity is 35 tonnes for full rake of 58 loaded wagons of 110T capacity.
