Rotary Table & Kelly Bushing

3d model of a Rotary Table & Kelly Bushing for technical graphics purposes.

Available in 3Ds Max, 3Ds, IGES, FBX and OBJ

The rotary movement from the rotary table is transmitted to the bushing through the pins, and then to the kelly itself thru the rectangular or hexagonal flat surfaces between the kelly and the kelly bushing. The kelly then turns the entire drillstring due to the fact it is screwed into the top of the drillstring itself.
