A method for, in particular completely or partially, disassembling a tower of a wind power plant, comprising the following steps: selecting suitable disassembly measures as a function of the tower location and the tower characteristics; preparing the disassembly, in particular of the tower and optionally the surroundings; carrying out the disassembly; and transporting the disassembled tower away.

An actuator pin incorporating a lateral stabilizer for an upper jaw of a demolition shear. The actuator pin includes a head. The head has an outer periphery configured to be receivable within a complimentary configured keeper attached to one side of the clevis end of the actuator such that the head is rotationally fixed with respect to the keeper. A pin cap is secure to a distal end of the pin. The pin cap has an outer periphery configured to be receivable within a complimentary configured keeper attached to another side of the clevis end of the actuator such that the pin cap is rotationally fixed with respect to the keeper.

A jaw assembly for a demolition tool is disclosed. The jaw assembly may have a support portion centrally disposed on a second jaw. The support portion may have a first contact surface and an aperture disposed thereon. A work plate may be mounted on the support portion and may have a plate member in abutting contact with the support portion. The work plate may also have a tooth member and a boss extending in a direction opposite to the tooth member. The boss may be engaged to the aperture. The jaw assembly may have a pair of seating portions disposed on the second jaw, each seating portion having a slot. The jaw assembly may also have a work module mounted in each seating portion. The work module may have a base, a tooth, and a mounting element extending in a direction opposite to the tooth and engaging the seating portion.

A replaceable tip for a demolition tool tip may include a first sidewall having a first contact side; a second sidewall having a second contact side; and a center wall connecting the first sidewall and the second sidewall. The center wall may have a third contact side provided with a recess, the recess may have first and second abutment surfaces, and the third contact side may have a third abutment surface adjacent the recess. A channel may be defined by the first, second and third contact sides, and the channel may be configured to receive an adapter of the demolition tool.

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.

A demolition system includes a frame, a plurality of outriggers, a demolition apparatus, and a water reservoir. The frame includes a frame base, a plurality of support members coupled to the frame base, a platform coupled to the plurality of support members, and one or more lifting ears extending from the platform. The plurality of outriggers are coupled to the frame base. The demolition apparatus is coupled to and supported by the frame base. The demolition apparatus includes a main body rotatably coupled to the frame base, an arm extending from the main body between two of the plurality of support members, one or more gripping members coupled to the arm, and a motor configured to selectively rotate the main body relative to the frame base. The water reservoir is coupled to and supported by the platform of the frame. Additionally, the water reservoir provides water to the demolition apparatus.

A pulverizing attachment for an excavator and a method of removably rigidly retaining teeth to one or more jaws of a pulverizer. A plurality of tooth members each have a longitudinal slot with a cross-sectional shape and a relief slot extending substantially transverse to the longitudinal slot producing a flexible end portion capable of deflection upon application of a longitudinal compression force. The tooth rails having a complimentary cross-sectional shape to the longitudinal slot slidably receive the tooth members. The complimentary shape of the longitudinal slot and tooth rail in cooperation with a longitudinal compression force applied to deflect the flexible end portions of each of the tooth members rigidly retains the tooth members on the tooth rails fixed to the pulverizer jaws.

A fluid discharger includes: a discharge nozzle configured to discharge fluid; a first rotation device configured to rotate the discharge nozzle; and a control device configured to control the first rotation device by remote operation. The control device includes a first mode control unit including a first automatic control unit configured to automatically perform reciprocating control of the discharge nozzle in a first rotation range set for each of the fluid dischargers; and a first switching unit configured to switch between a control signal to be outputted from the first automatic control unit and a control signal to rotate the discharge nozzle by a first rotation angle designated by remote operation. In a dust suppression system, this configuration can control the direction of the discharge nozzle by remote operation, and also can automatically reciprocate the direction of the discharge nozzle within a predetermined range.

A remote-controlled demolition robot has improved field of application The demolition robot includes a chassis, a base with a rotatable top, a moveable arm, a working tool, a controller, and a remote-control intended to be impacted by an operator. The demolition robot is arranged to give commands that are registered by the controller for operation of the remote-controlled demolition robot. The demolition robot also includes a broadcaster and an image sensor, which can register first image data and second image data of a scene of surroundings of the demolition robot from at least two different view directions. The broadcaster can communicate with an image display, which is arranged to show, in real time, an image area of the scene to an operator, who can control and operate the demolition robot through indirect viewing.
