Since it is held in place, it does not require a reader as in conventional work, and the capacity of the floating crane can be further reduced. Further, since the catch forcibly holding portion is rotatably mounted via the rotary bearing 24 and the cylinder 23 as in claim 2, the position of the catch fork in the circumferential direction can be easily adjusted. Further, according to claim 3,
A large number of piles can be driven by simply sliding the hanger 25 with the cylinder 27 without moving the platform A, which is efficient. Furthermore, since the base portion is pivotally supported by the pin 28 as in claim 4, the cylinder 29 can be horizontally rotated, and the position adjustment becomes easier.
