摘要： Inner surfaces of two guard plates (11a) forming a piping guard (11) abut against end surfaces of nut bodies (13) fixed to opposite left and right side surfaces of an arm (8), and bolt through holes (11c) made in the guard plates (11a) are opposed to attachment positions of the nut bodies (13) corresponding thereto, respectively. Then, front end portions of the bolts (12) penetrating the bolt through holes (11c) are screwed into the nut bodies (13). Thus, the piping guard (11) is attached to the arm (8). Stoppers (14) are attached to places of the inner surfaces of the guard plates (11a) to abut against a front end portion of the arm (8) or against the nut bodies (13), to thereby prevent a shearing force from acting on the bolts (12). Thus, it is possible to provide an attachment structure of a piping guard in which the piping guard can be attached to an arm stably without any shearing force acting on bolts attaching the piping guard to the arm.

摘要： Provided is an arm for a construction machine, including an arm top formed by casting, being easily produced with high dimensional accuracy. The arm includes an arm body 14 and an arm top 25. The arm top 25 is formed of left and right arm top pieces P1, P2 individually formed by casting and joined together. The left and right arm top pieces P1, P2 include first left and right bosses 28a, 28b constituting a fist connection section 28, second left and right bosses 29a, 29b constituting a second connection portion 29, and left and right projecting wall portions 30a, 30b constituting a connection wall 30 connecting the first and second connection portions 28, 29 to each other, respectively. The left and right arm top pieces P1, P2 are joined together by welding at respective opposing surfaces of the first left and right bosses 28a, 28b, those of the second left and right bosses 29a, 29b and those of the left and right projecting wall portions 30a, 30b, thereby forming the arm top 25.

摘要： The present invention relates to an excavator arm having a rotation device. The excavator arm is connected to a boom of an excavator to be operated by a cylinder, connected with a bucket for excavation at the lower end through a quick coupler, and connected with a bucket cylinder for operating the bucket over the arm. The arm is divided into an upper arm and a lower arm and a rotation device that selectively rotates the lower arm at predetermined angles over 360° in both directions is fixed between the upper arm and the lower arm.
