It can move along rails with the ability to slew jib,which can change amplitude. The Cantilever of Bucket Wheel Reclaimer is evolves in the bucket-wheel excavator,and can make up the mechanized transport system with the Bucket-Wheel Staker and blet conveyor. With the progress of economy,the need of the Cantilever of Bucket Wheel Reclaimer is more and more. This paper is main about the designing of the structure of the bucket wheel and the slewing mechanism,which are all very important to the Reclaimer. In this paper,the driving between the pin gear and pinion is used to drive the bucket wheel run,this method have some advantage,for example,its structure is uncomplicated, so it is easy to manufacture,and the cost is lower. Also it is easy to take down and repair. In the slewing mechanism,the key is the rotor support. The theory
