MULTI-BOOM TYPE WORK MACHINE
To provide a multi-boom type work machine improved in connection efficiency of adjacent booms.SOLUTION: A multi-boom type work machine has a machine body, a boom device (40), an arm device, an attachment, and a connection device (70). The connection device includes right and left first brackets (72b), upper and lower first pin insertion holes, right and left second bracket (74b), upper and lower second pin insertion holes, upper and lower connection pins (76e), upper and lower pins inserting/withdrawing device (78a), right and left upper centering members (80c, 80e) supporting the upper connection pin from an above side so that an axial line of the upper connection pin aligns with the hole axial line of the upper second pin insertion hole, and right and left support members (90e) provided to a first boom (42) so as to support the upper connection pin from a down side. Each of the right and left support members is arranged separating from the right and left first brackets more than the distance in the right and left direction of the right and left first brackets and the right and left upper centering members.SELECTED DRAWING: Figure 4
