There are walking wheels, and the walking frame is rolled and arranged on the sliding track.

Preferably, locking holes are provided on both the bow fixed wall frame and the stern fixed wall frame; the bottom of the arm frame of the walking lying-bar crane is hinged on two sets of arm frame hinge seats, and the arm frame hinge seats are hinged at the bottom. A locking hole is provided, and the locking pin is inserted into the locking hole of the hinge seat of the boom through the locking hole to realize locking.

Preferably, the front end of the boom hinge seat is provided with a traction pulley block, the traction pulley block seat provided on the working deck is located in front of the fixed wall frame at the bow, and the cable of the winch is connected to the traction pulley block through the traction pulley block seat. Drive for walking squat-bar cranes.

Compared with the prior art, the beneficial effects of the present utility model are:

The utility model replaces the conventional ship hull structure by the platform frame body, which greatly reduces the cost, and the platform frame body can freely navigate to the construction position for operation after the propulsion power component is installed, which greatly improves the construction convenience; Compared with the hull deck, the working deck of the pontoon structure of the platform frame has a larger and more regular working area, so it is possible to install working devices such as squatting bar cranes and slewing cranes at the same time. In addition, the hanging bar crane adopts a sliding structure, so that it is convenient to lower the center of gravity when sailing, and improve the safety performance.
