Abstract: An object of the present invention is to perform excellent crushing on an SRC object to be crushed or RC object to be crushed (pillar, beam or the like). In the crushing machine of the present invention, a crushing machine outer case is provided with movable jaw main bodies, base portions of the movable jaw main bodies are provided at the pivotally supporting portions that are separated from each other by a predetermined space, crushing bodies are fixed to the pointy ends of the movable jaw main bodies, the movable jaw main bodies being configured so as to be able to perform opening and closing movement by means of hydraulic cylinders, and crushing blade lines of the crushing bodies are formed so as to follow the longitudinal direction of the movable jaw main bodies.

Abstract: The present invention provides an industrial waste cutting apparatus for cutting finely the industrial wastes generated from such as industrial products of a great variety of types and domestic products such as used materials and old furniture, regardless of whether they are soft or hard, so that they can be easily disposed off, and it is an object thereof to cut soft materials, which are especially difficult to cut, with a very high efficiency.

Abstract: A crushing machine having enhanced crushing efficiency. The crushing machine includes an outer casing having a fixed jaw and a movable jaw each having a crushing blade for crushing reinforced concrete. The movable jaw includes a crushing blade having a rear-side edge formed in a substantially right-angled shape with a small arcuate edge portion located at an angled edge portion thereof, and a front-side edge generally formed by a large arcuate edge portion. The rear-side edge of the movable jaw crushing blade is oriented to face in a longitudinally inward direction away from a distal end of the movable jaw. The inward orientation of the rear-side edge along with its substantially right-angled shape allow the movable jaw crushing blade to concentrate the load of the crushing machine to the small point of contact between the movable jaw crushing blade and the reinforced concrete, thereby maximizing the crushing efficiency of the crushing machine.

Abstract: A crushing machine for crushing such as concrete structural members of buildings includes: a crushing machine outer casing; a fixed jaw body provided fixedly on the crushing machine outer casing; and a movable jaw body provided movably on the crushing machine outer casing to effect an opening and closing operation in cooperation with the fixed jaw body; wherein a crushing blade formed substantially in a shape of a semicircular cutting blade is provided at a distal end of the movable jaw body. The crushing blade includes a rear-side edge which is formed in a substantially right-angled shape with a small arcuate edge portion located at an angled portion thereof and a front-side edge which as a whole is generally formed by a large arcuate edge portion. The rear-side edge is located at a position closer to a longitudinally inward direction side of the movable jaw body relative to the front-side edge.

Abstract: 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.

Abstract: A rotation adjusting apparatus in a crusher is disclosed which even if siding members of a rotational mechanism of the crusher wear in use, the wear is adjusted easily and rapidly. In the crusher, a rotational housing with a pair of pawls which crushes or cuts an object, such as a reinforced concrete or a steel frame, to be crushed or cut is held to a fixing member by a holding member such that a wear is adjustable, and the housing can be rotated to a desired rotational angle and fixed there by rotation restricters and a rotation stopper.

Abstract: A crusher is disclosed, which comprises a stationary blade and a movable blade, the movable blade being capable of being rotated by a driver, e.g., an oil hydraulic cylinder, toward the stationary blade to clamp an object to be crushed between the stationary and movable blades and crush the object. The movable blade has tip projections projecting outwardly so that an object projecting from a road or ground surface can be clamped at its stem between the tip projections of the movable blade and the tip of the stationary blade. The object thus can be crushed from the stem. The stationary blade has a hollow frame to reduce the weight of the crusher.
