摘要： PROBLEM TO BE SOLVED: To turn a bow around in an optimum mode by controlling the flow rate and flow direction of oil according to azimuth deviation that is the difference between set azimuth and bow azimuth. SOLUTION: On the basis of a signal from an azimuth sensor 11, an azimuth deviation computing means 15a of a control unit 15 computes azimuth deviation that is the difference between set azimuth and bow azimuth. On the basis of the computed result, a valve control means 15b controls a proportional valve unit 14 according to the direction and size of the azimuth deviation so as to switch the flow direction of oil and to change the flow rate of oil, thus holding the bow azimuth to the set azimuth.

摘要： PROBLEM TO BE SOLVED: To rescue an underlaid person by easily raising a beam and a column or the like by a small number of people by providing a screw type support tool which extends and contracts by rotating one to the other and by which one support seat can be connected to one end of a hydraulic cylinder by a connecting metal fitting. SOLUTION: A leg part is put below, and a lifting-up jack is self-sustained, and a lifting-up claw is inserted under a column and a beam to be raised. A piston rod of a hydraulic cylinder is elongated by vertically, repeatedly and swingingly operating an operation lever, and a lifting-up part is raised, and the beam or the like on the lifting up claw is raised. In a condition where the beam or the like is raised up to a prescribed height, a support base 20a of a screw type support tool 19 is arranged so as to be put below, and a screw lever 21 is rotated and elongated, and is supported by bringing a screw base 21a into contact with a lower part of the beam or the like. Here, an opening- closing handle of a hydraulic pump is rotated to the opening side, and pressure oil of a hydraulic cylinder of the lifting-up jack is discharged to the pump side, and the lifting-up part is lowered, and the lifting-up jack is pulled out.

摘要： PROBLEM TO BE SOLVED: To greatly shorten an allowance for hoisting and to safely perform the lifting work even at a narrow work site of a low ceiling by providing a pair of U-shaped cargo taking arms which scoop a workpiece in such a manner that they can be opened and closed. SOLUTION: A glove 1 is lowered in a condition of holding a cargo taking arm 10 at a previous turn position by an electric cylinder 30 and its position is aligned to an adequate height for a segment W. Next, the cargo taking arm 10 is closed by the electric cylinder 30. Then, an end part of the segment W is received into an opening part 10a of the cargo taking arm 10, and a horizontal bar 12 at a lower end of the cargo taking arm 10 is inserted into a lower side of the segment W to scoop the segment W up. Consequently, by winding up a lifting machine in this condition, the segment W is hoisted up and conveyed in this condition.

摘要： PROBLEM TO BE SOLVED: To facilitate the steering by setting a quantity of the hydraulic oil to be discharged from a hydraulic piston pump, and moving a piston rod in right and left at an equal distance in response to the number of revolution of a steering handle even if the steering handle is rotated in any direction. SOLUTION: When hydraulic oil is discharged from a B-port 16 of a pump 1 to a right cylinder 31a-R, a flow control valve 14 with pilot receives the pilot pressure from a right side, and moves left at the maximum distance, and the hydraulic oil is discharged from the B-port 16, and while the hydraulic oil is sucked from an A-port 15 to a cylinder and a tank 8. A remote control steering system 30 provided with a hydraulic piston pump 1 is easily obtained by exchanging a manual hydraulic piston pump in a conventional remote control steering system using a one-rod cylinder, and the piston rod of the one-rod cylinder 31 is moved at the same distance for steering by turning a steering handle 40 at the same number of rotation in both right and left direction. With this structure, steering operation is facilitated.
