Provided is an apparatus including an image capture device mounted on a flying object to support work by a work machine, including an information acquisition unit, an image capture target position calculation unit, an image capture condition setting unit that sets an image capture condition including at least one of an image capture view angle and an image capture direction, a flying object control unit capable of hovering control of the flying object, and a flight control command unit that imparts a control command to the flying object control unit. The flight control command unit makes the image capture condition setting unit change the image capture condition to make the image capture target position contained within the image capture area while maintaining the target flight state when the image capture target position is deviated or predicted to be deviated from the image capture area during the hovering control.

An attachment that is configured for attachment to an arm of a piece of heavy construction equipment. The attachment is configured to rotate a section of pipe during break-out (i.e. disconnection or disassembly) from another section of pipe and/or make-up (i.e. connection or assembly) with another section of pipe. The attachment is configured to break the joint or torque the joint, unthread or thread pipe, and lift the pipe under the power of the heavy construction equipment.

Extraction tongs with replaceable jaw tips include jaw tips with mating gripping projections. Each extraction tong includes a plurality of inward extending teeth. A thickness of the extraction tong is reduced at a bottom to form a jaw tip extension. A substantially triangular projection extends outward from opposing sides of the jaw tip extension. A plurality of holes are formed through the jaw tip extension. Each jaw tip includes a tong slot, which is sized to receive the thickness of the jaw tip extension. A substantially triangular slot is formed in opposing walls of the tong slot to receive the two substantially triangular projections. A plurality of counterbore holes are formed in opposing sides of the jaw tip. A first lengthwise projection is formed on a gripping surface of the first jaw tip. A pair of second lengthwise projections are formed on a gripping surface of the second jaw tip.

A demolition apparatus and an adapter frame of the demolition apparatus are disclosed. The adapter frame may be formed with coupling seats which engage pins on a jaw set to assemble the demolition apparatus. The openings of the coupling seats face different directions for quick and simple assembly of the demolition apparatus. A rotatable locking element may be provided on the adapter frame to lock a pin on the jaw set.

There is disclosed a system and methods of use for quickly and efficiently excavating, cross-cutting, splitting, and loading or stockpiling tree stumpage and other tree or organic materials, as well as for performing ground cleanup operations. One embodiment provides a stump harvester for attachment to a distal end of an excavator arm. The stump harvester may include front and back jaw assemblies configured to pivot between open and closed positions. The back jaw assembly may include a knife arm having a cutting blade that extends along a majority of a front side of the knife arm. A centerline plane may bisect a cutting edge of the blade. The front jaw assembly may include a planar-aligned dual anvil configured to sheath the cutting edge of the blade when the front and the back jaw assemblies move into the closed position. Other embodiments are disclosed.

The invention relates to a hydraulic cylinder, for example for use with a hydraulic tool, which hydraulic tool is provided with a frame and an element which is movable with respect to the frame by means of the hydraulic cylinder.

A hydraulic tool which is operated by means of a hydraulic cylinder as described above is known from, for example, European patent no. 0641618. This patent discloses a frame which is coupleable to a jib of an excavator or the like and to which an assembly of two jaws can be coupled. One of the jaws is pivotable with respect to the other jaw by means of a hydraulic adjusting cylinder (a double-acting piston/cylinder combination).

As shearing blades of a first jaw portion, a shearing machines includes: a tip blade; a pair of first parallel shearing blades bent at an obtuse angle to the biting direction of the tip blade and disposed both sides of the blade width; and a pair of second parallel shearing blades bent at an obtuse angle to an attaching portion of the first parallel shearing blades and disposed on both sides of the blade width. As a tip blade, the shearing machine includes: a point blade a pair of tip tapered blades disposed on both sides of an end portion and whose blade width is increased toward the rear end; and a pair of tapered blades bent at an obtuse angle to an attaching portion of the rear end portion of the tip tapered blades and disposed toward the first parallel shearing blades.

A shovel includes a lower travel body, an upper swivel body that is swingably installed on the lower travel body, an attachment that is installed on the upper swivel body, and a posture detecting device that detects a posture of the attachment, wherein a virtual plane is generated by utilizing information about a position of a predetermined portion of the attachment obtained from an output of the posture detecting device.

A core drill control device is coupled to an excavator via a fixed-type mounting part and a rotation-type mounting part. The core drill control device comprises: a power button for outputting a hydraulic provision signal; a first motor button for outputting a first motor operation control signal for causing the first motor to operate; a cylinder button for outputting a cylinder operation control signal for causing the cylinder to operate; a second motor button for outputting a second motor operation control signal for causing the second motor to operate; and a control unit for controlling so that a hydraulic pressure is provided from the excavator to a core drill module depending upon the hydraulic provision signal.

A cutting device capable of efficiently cutting an object with a simple configuration includes a grasp unit including a first grasper and a second grasper movable in an opening and closing directions to grasp the object, a cutting unit disposed side by side with the first and second graspers and moved in a cutting direction along the opening and closing directions to cut the object, and a position setter setting a cutting start position and a cutting end position based on respective positions of the first and second graspers that are grasping the object, respectively.
