ABSTRACT:
The pipe racker assembly includes a mast, a dolly assembly vertically slidably secured to the mast for vertical movement, a handling arms assembly rotatably secured to the dolly assembly and having an upper handling arm extensible to accommodate pipes of varying length and as long as 45 feet and lower arms capable of gripping pipe either from a horizontal pipe rack or from a carousel pipe rack turntable when the handling arms are rotated 90.degree. on the dolly assembly. A stabilizer is secured to the ends of the handling arms in order to allow the handling arms assembly to be supported remote from the pipe racker assembly to reduce the structural strength requirements of the assembly.
