摘要： A wear amount measuring device includes an image display unit, an image processing unit, and a wear amount computing unit. The image display unit displays a real object image based on real object image data containing a wear amount measurement target and a reference part, and displays a plan image based on design plan data containing the wear amount measurement target and the reference part. The image processing unit executes an image processing of overlapping the real object image and the plan image at an equal scale on a corresponding positional relation when the reference parts are matched. The wear amount computing unit computes a wear amount based on a magnitude of an interval between a measurement contour line drawn along a contour of the wear amount measurement target in the real object image and a plan contour line in the plan image.

摘要： A bucket tooth for a construction vehicle includes a through-hole formed in a side wall part and passing through to a cavity. The through-hole has on a cavity side a rotating body hole having a shape of a truncated and rotated cone that remains after removing a large diameter side portion obtained by cutting diagonally to a rotational axis of the truncated and rotated cone with a large diameter side of the truncated and rotated cone being disposed on the cavity side, and with the rotational axis of the truncated and rotated cone being inclined outwardly toward the distal end portion of the bucket tooth from the cavity along a width direction of the bucket tooth.

摘要： A work implement includes a ground engaging tool with a first through-hole, an adapter with a second through-hole, a retaining pin, a metal bushing and a metal retainer. The retaining pin is inserted into the first and second through-holes disposed in a state in which the ground engaging tool is in contact with the adapter. The retaining pin is inserted in an inside of an cylindrical member of the bushing, which is disposed at an end portion of the retaining pin inside the first through-hole. The metal retainer prevents the bushing from coming loose from the retaining pin by sandwiching the bushing between the metal retainer and the adapter at the end of the retaining pin. The bushing is disposed in a state that allows movement in an axial direction of the retaining pin between the adapter and the retainer on an outer peripheral face of the retaining pin.

摘要： A crawler belt and a master link for use in the crawler belt enable easy connection and disconnection of the crawler belt. The crawler belt has a track chain, in which a plurality of regular links are pivotally connected at their ends, the master link for connecting the ends of the track chain to form the crawler belt into a loop, and track shoes attached to the regular links and the master link respectively. The crawler belt has a slit aperture which leads only to a pin insertion hole formed at the other end of the master link and is configured such that a clamping force, generated by tightening a master bolt that imparts a tightening force to the master link to narrow the slit aperture, is allowed to work on only the regular pin inserted into a pin insertion hole leading to the slit aperture.

摘要： A bucket tooth assembly is mounted to an adapter provided to a distal end part of a bucket of construction equipment. The bucket assembly includes a bucket tooth and a latching member. The bucket tooth has a cavity for inserting the adapter and a through-hole that is provided to the side face and communicates through to the adapter when the bucket tooth has been mounted to the adapter. The through-hole has a center axis. The latching member is fitted inside the through-hole and having a rotational axis disposed along a direction of the center axis and a bottom part provided to an end on an adapter side in an axial direction. The latching member is rotated to switch between a first state in which the bottom part is held inside the through-hole and a second state in which the bottom part protrudes toward a concave portion on the adapter side.

摘要： A bottom surface part of a bucket includes first and second curved surface parts. The second curved surface part is positioned closer to a back surface part than the first curved surface part. A second curvature radius of the second curved surface part is shorter than a first curvature radius of the first curved surface part. The center of the first curvature radius is positioned to the outside of a main bucket body when viewed from the side. In a horizontal state, the first curved surface part is arranged along or above a reference curved surface when viewed from the side. A connecting part between the first curved surface part and the second curved surface part is positioned more towards a lip part than the portion of the bottom surface part that is positioned lowest in the bottom surface part in the horizontal state when viewed from the side.
