Abstract: A heavy-duty demolition shear with a replaceable shearing tip has a lower jaw and an upper jaw piviotally connected to the lower jaw. The upper jaw has primary and secondary shear blades. A replaceable shearing tip is mounted to the upper jaw. The replaceable shearing tip has two L-shaped sections which engage the upper jaw between them. The replaceable shearing tip engages the upper jaw on at least three seats. The replaceable shearing tip is connected to the upper jaw by socket-head cap-screws.

Abstract: Concrete-crushing pincers comprise a first pincer jaw and a second pincer jaw which are swivelingly connected to one another via a joint and which are movable from an open position into a closed position for demolishing a concrete structural member reinforced with reinforcing irons. The first pincer jaw is formed by a frame body. The second pincer jaw is formed by a body. The first pincer jaw and the second pincer jaw have concrete-crushing sectors and cutting elements. The cutting elements are detachably fastened in the first pincer jaw and the second pincer jaw and can be exchanged.

Abstract: A mobile jaw crusher assembly for crushing objects is provided. The assembly includes a frame and a first crushing member that is configured to be moved and at least partially rotated by a vehicle. The first crushing member is configured to be attached to the vehicle. A second crushing member is also present and faces the first crushing member. The first and second crushing members define a crushing chamber that is used for crushing objects. The second crushing member is configured to be moved and at least partially rotated by the vehicle.

Abstract: A comminution machine is provided for comminuting crushable materials such as rock, masonry and reinforced concrete, or shreddable materials such as motor vehicle tires. The machine comprises a hopper having an open top (11) tapering to a narrower discharge opening (12). The hopper has a curved anvil wall (6) and a curved and reciprocally pivotable crushing jaw (7). Movement of the crushing jaw (7) is controlled by a two-way hydraulic ram (9). The shape of the crushing jaw (7) is generally that of a spiral away from its pivotal axis in a direction from the bottom to the top of the hopper, with the result that reciprocation of the crushing jaw (7) imparts a mixture of compressive and shear forces on comminutable material in the hopper, the sheer forces increasing in proportion nearer to the discharge opening of the hopper.

Abstract: Concrete-crushing pincers comprise a first pincer jaw (1) and a second pincer jaw (2) which are swivelingly connected to one another via a joint (3) and which are movable from an open position into a closed position for demolishing a concrete structural member reinforced with reinforcing irons. The first pincer jaw (1) is formed by a frame body (6). The second pincer jaw (2) is formed by a body (7). The first pincer jaw (1) and the second pincer jaw (2) have concrete-crushing sectors (9, 10, 13, 14, 15, 16) and cutting elements (17 and 20). The cutting elements (17 and 20) are detachably fastened in the first pincer jaw (1) and the second pincer jaw (2) and can be exchanged.

Abstract: The breaker comprises two breaker jaws (17, 19) adapted to be opened and closed hydraulically, with which building parts, concrete parts, brick walls and the like may be clamped. A hydraulic pulse hammer device (25) is mounted to at least one breaker leg (17), which, by means of a piston (29) strikes on the object in the holding area of the breaker and breaks or splits the same. Thus, the efficiency of the breaker is substantially increased.

Abstract: The present invention provides an apparatus that lifts, secures, splits and/or crushes tree stumps or other materials, particularly wooden materials and other materials that may be present at an excavation site. The apparatus is characterized in part by a two pivot point design. A first pivot point allows for the pivotable operation of an engaging unit which grabs and lifts the tree stump. The engaging unit further acts a durable and secure support member for the tree stump during the splitting and crushing process. The second pivot point allows for the pivotable operation of a cutting device which facilitates splitting and crushing of the stumps.

Abstract: An apparatus for fiberizing bales of pulp into substantially dry fibers and fiber aggregates. One embodiment includes: a bale support member for supporting a bale of pulp, the bale support member defining two openings; two rotatable fiberizing assemblies having disrupting elements protruding through the openings an adjustable distance above the bale support member to contact a surface layer of the bale of pulp, the surface layer having a dimension parallel to the longitudinal axis of the fiberizing assembly, a transportation assembly for moving the bale of pulp back and forth along the bale support member and over the openings so that the disrupting elements contact a surface layer in the bale, an adjustable reciprocating assembly permitting adjustment of the frequency by which the transportation assembly moves back and forth over the opening.
