摘要： PURPOSE:To transfer cargos between a quaywall and the deck of a ship so as to shorten a cargo handling time and attain a safe operation by appropriately arranging transport passages for horizontal movement of cargos connecting togther a cargo terminal, the quaywall, transport passage bases, and the deck of a ship. CONSTITUTION:After leading a ship to a predetermined mooring position, the hull is lifted by means of a hull elevator device 3, and then a movable pontoon 4 is moved and fixed so as to be in response to the size and the construction of the ship. The transport passage 11 on transport passage bases 10, 13 on one side or both sides of the ship is conformed to the transport passage 15 on the deck 14 of the ship in height. A cargo is previously put in stand-by on one transport passage base with the elevator device, and unloading of the cargo loaded on the ship and loading of the cargo in stand-by are simultaneously performed. The transport passage 11 on the transport passage bases with the elevator devices loaded with the cargo having been loaded on the ship are conformed again to the transport passages 51, 52 of the quaywall 1 in height, and the cargo is moved to a terminal.

摘要： PURPOSE: To provide great destruction force and to ease a shock transmitted to a main body in an impact application time by connecting an accumulator communicated with a small cross section area part formed in the rear part of a piston, which can be moved forward/backward freely in a cylinder, to an intake pipe in a compressed air source via a check valve. CONSTITUTION: Based on a cross section area difference between the front and rear cross sections of a piston 3, which is moved forward/backward in a piston and provided with a small cross section area part in the rear part, the piston 3 is moved backward and pressurized air is accumulated in an accumulator 10. Then, a three-way selector valve 5 is opened when a stroke end of the piston 3 is detected, and air in front of the piston 3 is discharged from an air intake/exhaust port 6. Simultaneously, the piston 3 is suddenly advanced by means of air pressure accumulated in the accumulator 10 so as to hit a bit 1, and a hard rock-bed 13 is destroyed by means of the bit 1 with great destruction force. When the bit 1 is advanced according to this destruction of the rock-bed 13, the air intake/exhaust port 6 is closed, and empty hitting can be prevented automatically. A reaction force after hitting is absorbed by the air pressure connected to the air pressure accumulator 10. Consequently, a shock in the rock drill main body can be reduced.

摘要： PURPOSE:To make it possible to excavate and dredge the seabed in correspondence with variations in soil-cover of a seabed buried pipe without applying excessive load and to enable the trench dredging of the seabed buried pipe efficiently in the open sea, etc., having high waves by using a self-moving dredger without being drawn with a mother ship. CONSTITUTION:The front drum section A equipped with a dredging device 10 is connected to the rear drum section B having a posture holding device (11) through an expansion mechanism (13) and, at the same time, grippers 14 and 15 are provided respectively to the front drum section A and rear drum section B. The expansion mechanism 13 is expanded to advance while grasping a seabed buried pipe 16 with the front drum gripper 14 and rear drum gripper 15 alternately.

摘要： PROBLEM TO BE SOLVED: To make it possible to quickly and accurately adjust a horizontal position when an immersed tube is settled. SOLUTION: A settled structure A is suspended to pontoons 20a-20d floated on the surface of the water through hanging wires 31 controlled by winches and, at the same time, horizontal controlling wires 38a-38d, 39a and 39b fixing their ends to the bottom of the water are interlocked with the settled structure A in the plural directions. Hanging wire winches 30 for winding and drawing out the hanging wires 31 and horizontal controlling wire winches 35a-35d, 36a and 36b for winding and drawing out the horizontal controlling wires 38a-38d, 39a and 39b are mounted on the pontoons 20a-20d. The horizontal wires 38a-38d, 39a and 39b drawn out from the horizontal controlling wire winches 35a-35d, 36a and 36b are fixed to the bottom of the water through pulleys borne on the settled structure A, and a horizontal position of the settled structure A is adjusted with the control of the horizontal controlling winches in a state to hang down the settled structure A in the water with the hanging wires 31. When the hanging wires 31 are drawn out to settle the settled structure A, the horizontal controlling wires 38a-38d, 39a and 39b are synchronized with the setting velocity of the settled structure A and are drawn out by the same length as that of the hanging wires 31 to be drawn out.

摘要： PURPOSE:To effectively operate a vessel on a medium or small river having many bridges by outputting an instruction for the change of draft and an instruction for a navigation standby to the vessel based on data about navigation for the river on which the vessel is to be navigated. CONSTITUTION:The data about the navigation for the river on which a barge 1 is to be navigated, which are composed of a depth H of water, a height C of the girder of a bridge 2, etc., and vessel data composed of a height (h) of a hull highest part obtained from draft D and a water level W.L of the barge 1, etc., are processed in a CPU 3. According to the processing, the CPU 3 outputs an output to instruct ballast adjustment for the ballast tank of the barge 1. Further, the CPU 3 outputs an output of the instruction for confirming the clearance between the barge 1 and a river bed B based on draft data, etc., from a draft gauge 16 of the barge 1, executing the ballast adjustment so that the barge 1 never collides with the bridge 2, and changing the draft D. Further, when the depth H of water is insufficient by any chance, the output of the instruction for the standby is outputted from the CPU 3.
