An apparatus for handling pipes in a derrick and racking the pipes on a pipe racking assembly mounted on the derrick is provided to improve the stability of transferring pipes during a round trip operation. The apparatus includes a rotatable gate assembly mounted on the pipe racking assembly. The rotatable gate assembly includes a collar rotatably mounted to a first end of a shaft and an arm pivotably and rotatably mounted on a second end of the shaft. The collar defines a gate for securing an upper portion of the pipe stand. A first securing means mounted to a second end of the arm secures the mid-portion of the pipe stand and a second securing means mounted to the first securing means secures the lower portion of the pipe stand. After the arm secures the pipe stand from the derrick, a drive mechanism mounted to the shaft rotates the rotatable gaze assembly such that the arm may rack the pipe on the pipe racking assembly.
