摘要： This invention relates to a method for dismantling a cylindrical tank, comprising steps of separating the sidewall of the tank from its bottom plate, cutting the sidewall into portions along a spiral line provided on the periphery of the tank in the direction from the lower end to the upper end, and removing the portions while temporarily supporting the sidewall, said temporary supporting step being conducted so that the lower end of the removed portion is gradually lowered and the location to support the sidewall shifts as the removing step proceeds. According to this invention, one can safely and inexpensively dismantle a cylindrical tank. The method of this invention can be used even if some structures exist in the peripheral area of the cylindrical tank. Further, this method does not need a step for providing rotatably movable means or a step for rotating the upper part of the tank, resulting in a simple method that is easy to implement.

摘要： A crusher-is disposed at a distal end of an operating boom of a construction vehicle. The crusher permits the breaking of a crushed mass of natural stone by means of a breaking force occurring between a stationary jaw body and a movable jaw body as the movable jaw body is closed toward the stationary jaw body. A flat auxiliary member is replaceably disposed on the stationary jaw body opposing the movable jaw body so as to break the crushed mass into smaller pieces. The distal end of the stationary jaw body projects longer than the distal end of the movable jaw body to facilitate the raking out of the crushed masses obtained in a blasting operation.

摘要： A device for processing a concrete layer by water jets, comprising a jet tube on a carriage moveable to and fro along a guide. The jet tube is pivoted in planes substantially parallel to the guide and oscillates in planes making an angle with the guide. The jet tube is inclined in one direction along the extension of the guide during the movement of the carriage along the guide, and a control unit ensures that pivoting of the jet tube with an angular velocity leading to movement of a nozzle of the jet tube along the guide with a velocity substantially equal to the velocity of the carriage is initiated at the same time as the carriage is stopped in an end position, and the control unit starts the movement of the carriage in an opposite direction when the jet tube has finished its pivoting movement.

摘要： A demolition tool includes a carrier body and two tool blades mounted thereon to define a tool mouth for receiving material to be crushed. The demolition tool further has a hydraulic cylinder including a cylinder housing as well as first and second chambers defined therein. A piston rod is received in the cylinder housing and projects therefrom for moving at least one of the blades. First and second pistons are spacedly affixed to the piston rod and bound the first and second chambers, respectively. Hydraulic fluid is introducible into the first and second chambers for exposing the pistons to pressure to generate a force for moving the piston rod in a working direction. A control unit is operatively connected to the chambers for controlling admission of hydraulic fluid thereto. The control unit has a first position in which the control unit admits hydraulic fluid solely to the second chamber and a second position in which the control unit admits hydraulic fluid under pressure to the first chamber.

摘要： A working machine comprises a machine body provided with a pair of arms which are arranged for movement toward and away from each other. The machine body is disposed for rotation, relative to a bracket mounted on the machine body, about an axis. A hydraulic cylinder assembly has a single cylinder defining therein a hydraulic chamber, and a single piston mounted to a piston rod extending through the hydraulic chamber, the piston rod having opposite ends thereof, which extend respectively from opposite ends of the hydraulic chamber, and which are fixedly connected to the bracket. Upon introduction of hydraulic fluid into the hydraulic chamber, the cylinder and a rack fixedly mounted to the outside of the cylinder are moved in the direction perpendicular to the axis, so as to cause a pinion meshing with the rack and the machine body connected with the pinion to rotate about the axis, thereby changing the direction of the plane in which the arms mounted on the machine body are moved.

摘要： The breaking tongs with a tong body (7) for receiving two tong parts (1, 1'), each pivotable about its own rotation center (2, 2'), and spaced from the rotation center the tongs are subdivided into a tong lever (3, 3') for the force action and a cutting lever (4, 4') for exerting the breaking force. The tong protuberances (12, 61, 63) are detachably mounted on the cutting levers. In the vicinity of the tong cutting edge (4, 4') separating blades (6, 6') can be provided for cutting reinforcements. The detachable tong protuberances (61, 63) can be detachably fixed in a protuberance bed (60), which is detachably arranged or shaped on to the cutting lever (4, 4'). A plurality of tong protuberances can form a working profile, which differs as regards the breaking action from another working profile formed from the same or a different number of tong protuberances.

摘要： The invention relates to an apparatus for demolishing a reactor shield wall. The apparatus has a pillar (2) extending from the top side of the reactor toward the bottom of the reactor, an upper support device (3) for supporting the upper portion of the pillar (2) at the top side of the reactor, and cutting devices (5, 6) mounted to the pillar so as to be upwardly and downwardly movable along the pillar (2). The pillar (2) is rotatably supported by the support device (3). The upper support device (3) has drive devices (30, 31, 32) for rotating the pillar (2). The cutting devices (5, 6) are caused to swing in the reactor interior by rotating the pillar (2). The drive devices are disposed at the top side of the reactor, and this permits easy maintenance and inspection.
