摘要： PROBLEM TO BE SOLVED: To provide a vehicle provided with a frame support structure so as to prevent increase of weight of the vehicle as far as possible in the vehicle having an upper part structure body provided with a swivel mast on a turn device and a frame support structure arranging a forward/rearward side movable core member in each lengthwise sideward of the vehicle, arranging this fixed side core member in a circular arc shape into contact with a lengthwise direction axial center of the vehicle in at least one part, extended from one lengthwise sideward of a contour of the vehicle to its central inner side, and extended to the other of the same lengthwise sideward of the contour of the vehicle. SOLUTION: A fixed side core members 23, 24, 25, 26 of a forward/rearward side movable core members 14, 15, 16, 17 in each lengthwise sideward of a vehicle are arranged mutually one after the other while having a common carriers 27, 28 so as to extend the movable core member from corresponding both ends 29, 30, 31, 32 of the carriers 27, 28.

摘要： PURPOSE: To provide a concrete pump which can minimize the amount of fine dust generated and allows a nozzle to use a compressed air in an amount necessary for the wet type injection process at any moment as applicable. CONSTITUTION: Concrete is fed by pressure to a mixing nozzle, where a compressed air, and if necessary, a solidification accelerator, are mixed, and the obtained concrete flow is spouted from the nozzle and solidified. In this concrete pump to perform the wet type injection process, a control step 20 is installed whereby the feeding amount of the pump 1 is formed so that the target amount for controlling the rate of flow of the compressed air flowing into the nozzle 3 corresponds to the target value representing the minimum amount of dust generated when the concrete is applied about the ratio of the concrete amount to be fed by pressure per unit time to the current value of compressed air amount mixed per unit time.

摘要： PURPOSE: To improve transfer equality by successively providing operation cylinders in a storage cylinder to drive itself and enabling the specification of the finish position of the operation cylinders in an article to transfer the viscous matter in a transfer pipe by means of the reciprocation of a piston in the storage cylinder. CONSTITUTION: A storage cylinder 4 is connected to the middle of a transfer pipe 3, and operation cylinders 7 are successively provided in this cylinder 4. A storage piston 10 fitted in the storage cylinder 4 through the piston rod 9 connected to an operation cylinder 8 by the operation of an operation cylinder 7 is driven. In order to control the operation of the drive cylinder 7, two sheet valves 12 and 14 are provided to be controlled by a 2/2 directional control valve 15. The final position of the drive piston 8 is controlled by the control valve 32 attached to the driving cylinder 7, and switch position is selected so that all of the contents in the storage cylinder is press-fitted.

摘要： PURPOSE: To provide a device for pneumatic discharge of concrete that is hydromechanically transported in a dense flow. CONSTITUTION: A device described comprises a concrete pump 1 for the hydromechanical transport, a solidification accelerator dosing device and a device for pneumatic discharge of the hydromechanically transported concrete 2. At least one additional additive dosing device 500, 501, 502 with a linear piston pump 470, 471, 472 is arranged. The linear piston pump is connected to a linear piston drive 34-37. In discharge lines 480, 481, 482 of each additional dosing device, a distribution valve 490, 491, 492 for the redirection of the dosing agent into each one dosing agent tank 460, 461, 462 or into the dosing agent discharge line 8, 81, 82 is installed. The distribution valves are loaded with the pressure of the hydraulic medium prevailing in the piston chamber of working cylinders 25, 26.
