摘要： PURPOSE:To bring a working device to an emergency halt when there occurs an emergency by connecting one end of a hydraulic cylinder to a load and the other end of the cylinder to a working device and consisting of a set of two devices where each cylinder chamber is connected with a pipeline and detecting fluctuations in s distributed load of each cylinder. CONSTITUTION:A hydraulic pressure load distributor 7 connects one end of hydraulic cylinders 41 and 42 to a load and the other end to a set of two working devices which lifts up and down the load 5 respectively and communicates and interconnects a hydraulic chamber of each cylinder by way of a pipeline 5 and seals a working solution inside. In the case when some emergency occurs or particularly when the load is tilted, and a piston 44 of one hydraulic cylinder 42 comes in contact with the upper end of the other cylinder tube 4c, the hydraulic pressure in the pipeline is decreased than a fixed value P while a distributed load W2 of one hydraulic cylinder 42 is increased than the other load W1. These troubles are detected with the hydraulic load distributor 7 and two load detectors 81 and 82. At least when it is determined that these exist fluctuations in one distributed load or in the hydraulic pressure in the pipeline, an operation controller will halt the working device 2 on an emergency.

摘要： PURPOSE:To obtain a chucking method making it possible to execute chucking of a test piece of a round bar material to a chuck part reliably and firmly without machining for chucking. CONSTITUTION:A chuck part 1 is provided with a heating part 3 which can heat the whole of the chuck part to a prescribed temperature and with a hole 2 for chucking bored to be of a diameter being smaller a little than the one of a test piece 4. At the time of chucking of the test piece 4, the diameter of the hole 2 for chucking is enlarged by thermal expansion by heting the chuck part 1 by the heating part 3 and the test piece is fitted in this hole 2 of the enlarged diameter. Thereafter heating by the heating part 3 is stopped, the chuck part 1 is cooled and the diameter of the hole 2 is restored to the original one. Thereby slippage is prevented by a so-called shrinkage fit effect without machining for chucking, and thereby the test piece can be fixed surely in the hole for chucking.

摘要： PURPOSE:To allow the easy and efficient execution of inverting operations by crimping and inverting iron structural members with two sets of 1st and 2nd inverting arms and constituting this device in such a manner that both arms can move downward of the iron structural members in the state in which the 2nd inverting arms extend in the longitudinal direction of the iron structural members. CONSTITUTION:The 1st and 2nd inverting arms 4, 5 are made into one set and the inversion of the iron structural members 2 is executed in such a manner that the iron structural members 2 can be crimped by these arms 4, 5. The device is so constituted that the iron structural members 2 can be crimped by the two arms in the state that the 2nd inverting arms 5 rotate and extend in the direction orthogonal with the longitudinal direction of the iron structural members 2 and that the two arms 4, 5 can move downward of the iron structural members 2 in the state that the 2nd inverting arms 5 rotate and extend in the longitudinal direction of the iron structural members 2. The space to be used at the time of the inversion operations is minimized in this way.

摘要： PURPOSE:To systematically perform all operations, such as the position adjustment of a test piece, loading of a weight, and shock absorption at the time of dropping the weight by means of the same hydraulic circuit. CONSTITUTION:This hydraulic device is constituted of an elevating/lowering hydraulic cylinder 4 which elevates/lowers a test piece P, shock absorbing hydraulic cylinder 5 which absorbs shocks when a weight 3 is dropped, hydraulic unit 6 which drives the cylinders 4 and 5, control valve 7 which switches the piston rod 4a of the cylinder from an elevating/lowering state to a fixed state, or vice versa, flow control valve 8 which controls the speed of the rod 4a at the lowering time, and relief valve 9 which absorbs a impact load when the weight 3 is dropped onto the piston rod 5a of the cylinder 5. All operations are systematically performed by means of the same hydraulic circuit by performing the position adjustment of the test piece P, loading of the weight 3, and shock absorption at the time of dropping the weight 3 by driving the cylinders 4 and 5 by means of the unit 6.

摘要： PURPOSE:To make the pulling speed of a test piece variable and to improve testing accuracy by using hydraulic motors for the actuator of a driving device for the test piece, and selectively using a plurality of the hydraulic motors. CONSTITUTION:A weight is loaded on one end of a test piece through a lever. The test piece is moved with a driving device 3 in the axial direction. A hydraulic motor 4 is used for an actuator for the driving device 3. A plurality of hydraulic pumps 6A and 6B having the different discharge quantities are juxtaposed in an hydraulic circuit 5. When the fact that the weight which is loaded on the test piece reaches the lower limit position is detected with a sensor in this constitution, a directional control valve 7 for speed which is provided on the side of the hydraulic pump 6B is opened and closed. The hydraulic pump 6A or the hydraulic pump 6B is selected, and the test piece is pulled down. Therefore, the pulling speed of the test piece can be changed in response to the elongating speed of the test piece readily, and the testing accuracy can be enhanced.

摘要： PURPOSE:To obtain a simple and inexpensive lifter for structures which can safely and securely carry out lifting works and easily conduct installation works. CONSTITUTION:A pair of jacks 1 which are extensible upward are temporarily equipped on the base frame 6 and a hanging rod 2 is transferably positioned at the middle between the jacks 1. A plurality of pin holes 2b are formed at every equal distance in the axial direction of the hanging rod 2. And upper and lower clamp pins 4B, 3B are provided at the upper and lower ends of jack 1 respectively. The upper clamp pin 4B and the lower clamp pin 3B are inserted in the pin hole 2b of the hanging rod 2 by turns to exchange the hanging of the rod 2. A structure M is intermittently lifted both by the extensive actuation of the rod by the jack 1 on hanging the rod 2 by the upper clamp pin 4B and the drawing actuation of the rod by the jack 1 on hanging the rod 2 by the lower clamp pin 3B.
