The invention discloses a bendable combined arm frame for hoisting machinery. The bendable combined arm frame comprises a tractor, wherein the tractor is provided with a mounting seat; the mounting seat is used for overall rotation of the device; a rotating wheel seat is arranged at the upper end of the mounting seat; a limiting clamping strip is welded at the upper end of the rotating wheel seat;the limiting clamping strip is in sliding connection with one end of a pneumatic supporting column; the other end of the pneumatic supporting column is rotationally connected with a main hoisting frame; one end of the main hoisting frame is rotationally connected with an auxiliary hoisting frame; a hoisting rod is welded at the upper end of the main hoisting frame; and the main hoisting frame, the hoisting rod and the auxiliary hoisting frame form a crane main body. According to the bendable combined arm frame disclosed by the invention, the main hoisting frame is rotationally connected withthe auxiliary hoisting frame, and the auxiliary hoisting frame can rotate by 180 degrees, so that the aim of rotating the combined arm frame is achieved, and a wider working range is realized. Moreover, the main hoisting frame, the auxiliary hoisting frame and the hoisting rod are connected into a triangular structure by virtue of a suspension cable, so that the whole device is stable and balanced, and heavy goods can be hoisted.
