Construction machine boom mount device
Provided is a construction machine boom mount device that can easily position both an upper frame and a boom of a construction machine when mounting the boom to the upper frame. An upper frame (31) has a center section (4) that includes a pair of right and left vertical plates (43L, 43R). The vertical plates (43L, 43R) have exterior faces that face to the outside, and guide units (431L, 431R) that are disposed on the exterior face and have guide holes formed therein. An adapter (7) that links the basal end of a boom and the basal end of a boom cylinder so that each can rotate is mounted to the basal end side of the boom. The adapter has a pair of right and left guide pins (75L, 75R). When the boom is mounted to the upper frame, the pair of right and left guide pins are inserted in the guide holes of the pair of right and left guide units.
