The pipe racker assembly (10) includes a mast (28), a dolly assembly (B) vertically slidably secured to the mast (28) for vertical movement, a handling arms assembly (C) rotatably secured to the dolly assembly (B) and having an upper handling arm (77) extensible to accommodate pipes of varying length and as long as 45 feet and lower arms (78) capable of gripping pipe either from a horizontal pipe rack (R) or from a carousel pipe rack turntable (T) when handling arms are rotated 90 DEG on the dolly assembly. A stabilizer (D) is secured to the ends of handling arms in order to allow the handling arms assembly (C) to be supported remote from the pipe racker assembly to reduce the structural strength requirements of the assembly. <IMAGE> |
