Abstract

PURPOSE: To reduce weight of a boom and further the cost of manufacture by forming both side face plates of the boom of a steel plate with a U-shaped section, making the plates opposite to each other at a space connecting them fixedly through a base end boss and a point end bracket of the boom.
CONSTITUTION: A pair of right and left side face plates 27R, 27L of a boom in a work attachment 17 are formed out of a steel plate whose sections in the lengthwise and the right-angular direction are formed in a C shape. Both the side face plates 27R, 27L are opposed, so that the side ends of upper and lower cross plate parts 29, 29', 30, 30' are placed respectively at spacers from each other, and fixedly connected through a base end boss 20 and a point end bracket 22 of the boom 16. Tightening metal fixtures of pipes 19 are arranged in an interior side of the boom 16 by arranging the pipes 19 for the work attachment through the interior of the boom 16. In this way, necessity for upper and lower face plates over a total length of the boom 16 is eliminated, and further external appearance can be orderly arranged.
