摘要： PROBLEM TO BE SOLVED: To provide a shaft excavator capable of making widening excavation for widening in the horizontal direction and being efficiently excavated even if it is a shaft having a large section. SOLUTION: A vertically pivoting boom 6 is mounted on an operatable swivel base 3 swinging on a traveling truck 2, and a rotational excavation head 22 having a conical trapezoid is put downward on the front end of the boom 6 so as to enable it to oscillate in front and behind by a tilt driving mechanism 8. A plurality of picks are spirally arranged and are projected to the lower surface and the circumferential surface of the rotational excavation head 22. The ground can be excavated in the vertical direction by the rotational excavation head 22, at the same time, the widening excavation can be made in front and behind by oscillating the rotational excavation head 22 in front and behind by the tilt driving mechanism 8, and the boom 6 is rotated with the rotation of the operatable swivel base 3 to enable the widening excavation to sideways carry out by the rotational excavation head 22.

摘要： PROBLEM TO BE SOLVED: To prevent the end part sides of a thrust member from being opened to excess by detecting the case where the end parts of the thrust members exceed the permissible limit positions in the separating direction by a sensor to stop the supply of oil pressure. SOLUTION: The front end surface of a base end member 11 is provided with two sensors 12 opposite to the rear ends 2a of thrust members 2. When the rear ends 2a are in the range from the standby position to the permissible limit position to the sensors put in the permissible limit position, the end surfaces of the rear ends 2a overlap the sensor 12 to be detected to be present, and a detection signal is output. A rock cracking device 1 is provided with a stop device 13 for stopping the supply of oil pressure to a rubber tube if necessary, an output signal is dispatched from the sensor 12 to the stop device 13, whereby when a detection signal of the presence is received from the sensor 12, the operation of an oil pressure supply source is not stopped. Thus, the supply of oil pressure can be stopped by the operation of the stop device 13 so as to prevent burst of the rubber tube.

摘要： PURPOSE:To make it possible to cut off the internal surface of a tunnel safely and efficiently by providing a movable stand on a base capable of moving in the direction of the tunnel, and providing a cutter head to a cutting arm section mounted to a turning head capable of rotating around the directional of the tunnel. CONSTITUTION:The height is controlled by an outrigger 35 of a cutting device, and the cutting is stabilized by a side jack 36. After that, a cutter head 1 is fitted to a cutting position by expansion of a positioning jack 30, and after the direction is controlled by expansion control of a cutter head correction jack 29, an arm turning board 31 is rotated to cut off the internal surface. Then, after the cutting off of one cycle in the circumferential direction is completed, a movable stand 39 is moved forward by expansion of a hydraulic cylinder 37, and cutting off operation is repeated. The positioning jack 30 and movable stand 39 are operated simultaneously to correspond with the variation in curvature. According to the consitiution, the internal surface of the tunnel can be cut off with a high degree of accuracy.

摘要： PURPOSE:To obtain an ample pressing force with a comparatively low hydraulic pressure without using a hydraulic cylinder by expanding two thrust members through a wedge abutting on the outer peripheral surface of a rubber expanded by hydraulic pressure. CONSTITUTION:In a pressing operation, an object to be pressed is inserted between an active plate 2 and a passive plate 3 and hydraulic pressure is supplied uniformly from a hydraulic pressure generating device to the rubber tube 6 through a manifold 9 and a hydraulic pipe 8. The rubber tube 6 having a closed top end is expanded by this hydraulic pressure and pushes the wedge 7 in contact with the tube sides forward. As a result, each wedge 7 bites between the thrust members 5 in the shape of a wedge and expands the thrust members 5. Since in one of these thrust members 5 its displacement is regulated by a base 10, the other thrust member 5 is pushed up as a result and the object is pressed between the active plate 2 supported by this thrust member 5 and the passive plate 3.

摘要： PURPOSE:To enable drilling a trench even at a vicinity of an obstacle by supporting a cross rail guiding a guide to a lateral direction with an arm, and sliding the guide toward an extension part of the cross rail protruded to a side part from a vehicle body. CONSTITUTION:A cross rail 3 is joined to a tip of an arm 2, and vertically rotated according to expansion and contraction of a derricking cylinder 4 in a space with a back hoe main body 1. A guide 7 is made to slide in a lateral direction to the cross rail 3 via a slide plate 8. A trencher main body 6 is supported in an inner side of the guide 7 to be slid with the derricking cylinder 4 contractedly driven. Moreover the trencher main body 6 is moved to a drilling position, an elevating cylinder 21 is contracted by toroidally winding a bit 17 with a mounted special chain 16 with a motor 18 driven, and drilling trench is made with the rotating bit 17. This enables efficient drilling in a vicinity, etc., of a building.
