CASING ROTATOR
Disclosed herein is a casing rotator capable of distributing loads applied to bearings to protect the bearings even though verticality of a casing is not matched with verticality of an intermediate frame or an upper frame of a rotator. The casing rotator includes a lower frame unit, an intermediate frame unit, an upper frame unit, a clamping cylinder, and a post unit. The lower frame unit includes a lower frame, an outrigger, and a retainer portion. The intermediate frame unit includes an intermediate frame, a drive motor, a clamp body, and a drive bearing. The upper frame unit includes an upper frame, a wedge clamp, and an upper bearing. The clamping cylinder is configured to be stretchable. The post unit includes a guide post, a lower guide, a crowd cylinder, and an upper guide.
