Abstract: A working machine including front and rear wheels or a pair of endless tracks supporting a body. A first working arm with a first implement mount is connected to the body. An apparatus with a collector having a first opening and a sweeper trailing the collector is mounted to the first implement mount. A second implement mount connected to the body, and a milling device is mounted to the second implement mount. The sweeper is configured and arranged to move surface material broken up by the milling device into the collector via the first opening.

Abstract: Provided is a vibration-type nipper. The vibration-type nipper comprises a body including a vibration space and a coupling unit for coupling with a boom positioned at an upper portion or a fixing bracket of heavy equipment, a housing positioned in the vibration space and including a vibrator, a plurality of supporting means supported to opposite sides of the housing and the body corresponding to the housing and supporting the housing allowing the housing to vibrate, a nipper blade installed on the housing and extending downwards, and vibration-dampening means mounted on the body at an upper portion of the vibration space and distributing vibration generated when the housing collides with the body due to elevation of the housing.

Abstract: A blade assembly for an earthworking implement has a set of teeth that are independently slideable within guides. The teeth slide to conform to an undulating surface and permit scraping of the surface.

Abstract: The quad track vehicle includes a chassis including a front end, a rear end and a left side and a right side. The chassis is supported on a plurality of tracks. Each of the tracks defines a generally triangular shape. The plurality of tracks includes a front left track at the left side of the chassis, a front right track at the right side of the chassis, a rear left track at the left side of the chassis rearward of the front left track and a rear right track at the right side of the chassis rearward of the front right track. The rear tracks have rearward portions that project a first distance rearwardly beyond the rear end of the chassis. The front tracks have forward portions that project a second distance forwardly beyond the front end of the chassis. The second distance is less than the first distance.

Abstract: The invention relates to a hinged tooth for a cutting wheel comprising a pivot bearing for pivotally supporting on a pivot pin located on a cutting wheel hub, a cutting tooth support extending from the pivot bearing and a steering arm extending from the pivot bearing substantially in a direction opposite to that of the cutting tooth support. A simple and at the same time stable arrangement is achieved in that the pivot bearing, the cutting tooth support and the steering arm are designed as a one-piece support.

Abstract: A tamping tine for tamping ballast underneath a railroad track has a tine shank and a tine pad attached to the shank. For increasing its abrasion resistance, the tine pad is formed with a pad casing of wear-resistant material. The pad casing is formed with an opening and it is filled with core material. The core material is suitable for welding to the tine shank and it is attached thereto by way of a welding seam.

Abstract: The invention concerns a method for automatically moving on the ground a tool mounted at the end of an articulated arm. It consists in bringing the tool (7, 17, 27) onto a first point of the surface and in calculating the co-ordinates of said point; in bringing the tool onto a second point enabling to set a first axis of co-ordinates of the working plan and to determine the furthermost point to be reached on said axis; in bringing the tool onto a third point close to the second co-ordinate axis and enabling to define the position of the frame of reference of the working plan, then in a fourth point delimiting the zone plane inside which the work will be performed and in defining a working plan for the tool capable of being superimposed with the working surface so as to enable it to cover, by discontinuous or continuous movements, the entire working surface.

Abstract: A ground engaging tool that oscillates in a motion, relative to the ground, that is substantially vertically upward, and then downward and forward in a direction in which the apparatus is moved.

Abstract: An excavation bucket incorporating an impact actuator assembly is described herein. The excavation bucket includes a bucket body, a movable head, a movable floor portion mounted to the movable head and an impact actuator provided between and mounted to the bucket body and the movable head. The movable head is longitudinally movable in the bucket body. The movable head is provided with tools, such as teeth, to penetrate hard soils. These tools are slidably mounted in the movable head to reach a retracted position when they are pushed against hard soil. When the impact actuator is activated, the longitudinal impacts generated by the impact actuator drive the tools into the hard soil if the tools are in their retracted positions. However, if the impact actuator is activated while the tools are not in their retracted position, the longitudinal impacts will cause the repetitive longitudinal movements of the movable head and thus of the movable floor with respect to the bucket body.

Abstract: A hammer-ripper system for use with the mounting on the boom arm, of an excavator/backhoe, of a conventional hydraulically-operated hammer fitted with a “shortened” chisel. A “ripping-type” device like a chisel tooth mounts to a lever with its pivot point attached to the side of the hammer. One end of the lever extends to be impacted by under the shortened chisel, while the other end extends inward. Thus, the tooth end can be placed under embedded boulders and used to hammer (using the transmitted reciprocating action of the hydraulic hammer), and pry or break up the boulders from underneath with the combined hammering and ripping action.

Abstract: An excavation bucket incorporating an impact actuator assembly including a bucket body, a movable floor portion and an impact actuator provided between and mounted to the bucket body and the movable floor portion is described herein. The movable floor portion is longitudinally movable in the bucket body. When activated, the impact actuator assembly generates longitudinal impacts onto the movable floor portion to cause the repetitive longitudinal movements of the floor portion with respect to the bucket body. A forward edge of the floor portion is provided with tools such as teeth to penetrate hard soils.

Abstract: The invention relates to a vibration bucket arrangement comprising a bucket part (1) that comprises a bottom (2), a rear part (3) and lateral end parts (4 to 5). The arrangement further comprises an attachment part (6, 8, 9, 9a to 9d, 99) with which the bucket part (1) can be attached to a construction machine, and a vibration unit (10) attached to the bucket part (1), which unit comprises a vibrating assembly, such as a wabbler (10a, 10b) to be used by a regulating element. The arrangement further comprises a flexible attachment (30) on which the bucket part is arranged. In accordance with the invention, the vibration bucket arrangement comprises a locking and releasing assembly (16, 17 to 22) for locking the flexible attachment (30) of the bucket part essentially rigid when moving from vibration use to bucket use and for releasing the locking when moving from bucket use to vibration use.

Abstract: A snowblower chisel attachment includes an oscillatable elongate blade member oscillatably disposed at a bottom front of a snowblower housing; a pair of support arms pivotally suspended from the sidewalls of the housing and being secured to the oscillatable elongate blade member; a pair of stub shafts journaled through the sidewalls of the housing; a pair of three lobed cams mounted to the stub shafts for contacting and urging the support arms and intervally urging the oscillatable elongate blade member forwardly relative to the housing; a plurality of sprockets for rotating the stub shafts and the cams; a pair of biased elements for urging the oscillatable elongate blade member rearwardly toward the housing; and skid members for vertically positioning the oscillatable elongate blade member relative to the surface.

Abstract: A characteristic feature of the present invention is that a damping unit is rovided between the casing, impact tool and elements of a pneumatic hammer. The damping unit may have a different design.
