360° REVOLVING SUPER PILING BARGE FOR HARBOR CONSTRUCTION
Multi-functionality makes for a high level of safety and productivity in a variety of operations in the sea.
Three spuds are provided, on one either side and one at the stern of the ship. The one at the stern is variable through an angle of ±20°fore and aft, which is very effective in controlling the attitude of the hull while driving piles in diagonally.
Pump jets rotating through 360°are provided at the bow and stern, permitting speedy positioning of the ship and pile driving under conditions of tidal flow as well.
Sliding leader (18m slide) allows the leader to be slid up to 75m above the surface of the sea to faciliate operations under a variety of conditions. The bottom of the sliding leader reaches the sea surface even during diagonal pile driving at +25°.
Electrically operated gondolas (loaded weight 200kg, capacity 3 persons) are provided on the left and right sides of the sliding leader. The gondolas are always retained in a horizontal position irrespective of the angle of the leader, greatly improving safety.
Storage is possible on the leader rest with the leader and catch-fork attached, thus conserving energy and increasing safety.
The crane gantry is the folding type, so that the height of the vessel is no more than 20m above the surface of the sea, thus contributing to safe towing.
The operational platform is positioned on top of a hydraulic lock pile keeper, safety being improved by virtue of the fact that it is always kept horizontal with the aid of a hydraulic cylinder.
An automatic remote rebound measuring device eliminates human error and permits highly accurate measurement of rebound (patents pending)
A next-generation construction control system with GPS and automatic tracking TS serves both to conserve energy and increase accuracy, greatly improving performance.
By attaching a large-diameter fully rotating excavator to the leader it is possible to bore through hard rock layers and handle all types of soil.
This system has been developed with the aim of increasing the efficiency of steel tube pile-driving operations by pile-driving vessels. The position of the pile-driving vessel is measured with the aid of RTK-GPS by a fixed GPS station located at a reference point on land and two GPS’s located on board the vessel, thus allowing the position and direction of the vessel to be pinpointed. The positions of the piles are determined by establishing the positions of two points on the pile leader with the aid of automatic tracking TS located on board the vessel.
Reflecting mirrors are attached to the pile leader and hammer, making it possible to determine the three-dimensional position of the pile leader and the height of the pile head. Data measured by each instrument is relayed by a telephone or radio data relaying device to a control device(computer), and the position of the pile, direction of slope, angle of slope and height of the pile head are calculated.
Latest fitting allow work to be done speedily and accurately. Operating the steering-wheel causes a signal to be sent from the electronic circuit to an electro-magnetic valve, a hydraulic motor is driven by the pressure of the oil fed from the hydraulic pump,and the propulsion unit is driven by way of gears. The propulsion unit rotates and tracks automatically to the rotational angle (thrust direction) indicated by the tracking transmitter located on top.
