An integral rescue accessory for forcible entry and core drill may include hydraulic wall saws, a rotating platform, and a coring claw. Two hydraulic wall saws are symmetry installed on rotating platform. The wall saws cut linearly with the rotation of rotating platform to open a rectangular tunnel on a reinforced concrete wall or floor. After the cutting process, coring process is finished by the wall saws and claw inclinedly mounted to ensure the security of rescue. The whole accessory is installed on a large engineering machine through a hydraulic joint. The present disclosure can transfer general large mechanical equipment into dedicated large mechanical equipment quickly.

This disclosure relates to a method of mining a rock formation using a disc cutter and a rock breaker tool. Several examples of rock breaker tool are provided, including mini disc cutters and a form of hydraulic striker. The tool is inserted into slits cut into the rock by the disc cutter and activated, causing crack initiation and propagation in the rock.

The present invention relates to a device (10) and a method for removing contaminated material from a wall, the device (10) comprising suction plates (26) which fix a support system (13) of the device (10) to the wall by means of negative pressure, and a first rotating tool (14) that has impact cutters (16) in the circumferential direction. Disc-shaped saw blades (20) are provided in a second rotating tool (18) mounted upstream of the first rotating tool (14) in the working direction.

A dividing groove forming device includes: a first cutter including a plurality of first rotary blades; a second cutter including a plurality of second rotary blades; a first rotation drive unit for rotationally driving the first cutter; a second rotation drive unit for rotationally driving the second cutter; a cutter support unit; and a phase adjustment unit. The cutter support unit supports the first cutter and the second cutter such that the first and second cutters are radially opposed to each other so that rotation axes of the first and second cutters are parallel to each other. The phase adjustment unit adjusts a phase of at least one of the first cutter and the second cutter such that the first rotary blades and the second rotary blades are opposed to each other in an opposing area in which the first cutter and the second cutter are opposed to each other.

A substrate cutting device includes: a first cutter including a plurality of first rotary blades; a second cutter including a plurality of second rotary blades; a first rotation drive unit for rotationally driving the first cutter; a second rotation drive unit for rotationally driving the second cutter; a cutter support unit; and a phase adjustment unit. The cutter support unit supports the first cutter and the second cutter such that the first and second cutters are radially opposed to each other so that rotation axes thereof are parallel to each other. The phase adjustment unit adjusts a phase of at least one of the first cutter and the second cutter such that each of the second rotary blades is located between two adjacent first rotary blades in an opposing area in which the first cutter and the second cutter are opposed to each other.

A cutting apparatus for cutting corner pieces formed of stone or other materials for use as building faces or for cutting flat pieces is disclosed herein. The cutting apparatus includes a frame with a first and a second conveyor operatively attached to the frame. The first and the second conveyors are configured to carry a workpiece from a first end of the frame to the second end of the frame. The first conveyor is disposed at an angle of about 45 degrees to a ground surface supporting the cutting apparatus. The second conveyor is disposed at an angle of about 45 degrees to the ground surface supporting the cutting apparatus, wherein the second conveyor is positioned perpendicularly to the first conveyor so as to form a V-shaped channel therewith. The cutting apparatus further includes a first cutting blade operatively attached to the frame and positioned generally parallel to the first conveyor and a second cutting blade operatively attached to the frame and positioned generally parallel to the second conveyor.

A brick cleaning system has: a frame; a first saw comprising a first motor and a first saw blade driven by the first motor, the first saw being connected to the frame; a second saw comprising a second motor and a second saw blade driven by the first motor, the second saw being connected to the frame; and a brick cart connected to the frame. The brick cart is configured to hold a brick. The brick cart selectively translates relative to the frame for feeding the brick in a space between the first and second saw blades such that the first and second saw blades remove mortar from opposite sides of the brick. A method for cleaning used bricks is also disclosed.

Machine (1) for machining slabs (L) made of stone, stone-like, agglomerate or ceramic material, comprising a pair of fixed support structures (12) intended to delimit a working area (A), a horizontal surface (8) for supporting the slabs (L) being machined, which is positioned within the working area (A), a fixed horizontal beam (14) supported by the fixed support structures (12) and a horizontal beam (18) movable with respect to the fixed horizontal beam (14) and comprising at least one spindle (20) slidably mounted on the movable horizontal beam (18) and designed for the mounting of at least one machining tool (22). Also provided are means (32) for moving the movable horizontal beam (18) with respect to the fixed horizontal beam (14) along a predetermined direction of advancing movement (Z) lying in a plane parallel to the support surface (8) and means (34) for rotation of the movable beam (18) with respect to the fixed beam (14) about a fixed rotation axis (R) arranged vertically. The invention also relates to a plant (100) for machining the slabs.
