Abstract: A twin-scrape dozer, capable of maintaining a satisfactory balance during earth loading, of loading a larger quantity of earth, of efficiently conveying earth even over a soft ground, and of adjusting the rate at which earth is scattered, has a crawler type tractor (1, 1A) equipped with a traveling mechanism, a front earth loading and ejecting device (10, 50), and a rear earth loading and ejecting device (30, 70). The traveling mechanism has track frames (2, 2A) at right and left sides of the vehicle (1, 1A), track shoes (5, 5A) and drive units (6, 6A). The earth loading and ejecting devices are provided at the front and rear parts of the vehicle (1, 1A), and are installed to be vertically movable with lift cylinders (13, 33, 56, 78). Each of the earth loading and ejecting devices is provided with a scraper (21, 34, 53, 75) and a bowl member (14, 41, 61, 81) pivotably connected together by pivot pins (22, 42, 62, 83).

Abstract: A groomer attachment for forklift vehicles includes an elongated rigid member having a top and a bottom. A pair of spaced-apart fork receiving pockets are connected to the rigid member. A flexible blade extends from the bottom of the rigid member. Preferably the rigid member has a front and a rear. The attachment then has a pair of spaced-apart flexible blades extending from the bottom of the rigid member, a first blade being adjacent the front thereof and a second blade being adjacent the rear thereof. The rigid member may be channel-shaped.

Abstract: In an excavating apparatus including a bucket removably coupled to a distal end of a hydraulically powered boom, a field-detachable and field-attachable ripper comprises a shank portion having a lower tip, a mounting portion disposed along an upper area of the shank portion and a detachable and re-attachable coupling element disposed along the mounting portion. The detachable and re-attachable coupling element secures the ripper to the bucket. There is optionally further included a detachable ripper tip coupled to the lower tip. The detachable ripper tip comprises a metal piece having a point disposed at a first end thereof and having a hollow disposed at a second end thereof. The hollow is adapted to accommodate the lower tip therein. The detachable ripper tip further includes an opening disposed on one side thereof and extending into the hollow. The opening is adapted to accommodate a fastener extending from the side and into the lower tip.

Abstract: The invention relates to a sweeping appliance for excavators of the type comprising a stick (1) and a bucket (4) carried by said stick via a transverse pivot pin (5), said appliance including a rotary brush (13) arranged at a free end of a holder (12) whose opposite end is articulated to said stick or said pivot pin to allow pivoting of the holder between a position remote from said stick, in which the brush can actively perform a sweeping operation, and an inactive position close to said stick. The holder (12) is divided into at least two parts (16,17), of which an outer, brush-carrying part (17) is rotatable relative to an inner part (16), more precisely by means of a rotary unit (25) operating between said two parts, thereby permitting the brush to turn about an axis extending at right angles to the axis of rotation of said brush.

Abstract: A carrier is described that adapts an excavator with an dozer blade to a tote bucket or scoop. The excavator carrier rests on the blade at its bottom with the blade serving as the back of the carrier. Dumping capability is provided by pivoting the carrier on mounting pins between a mounting bracket added to the back of the blade at its top and a corresponding mounting bracket on the carrier. A backhoe on the excavator can be used to lift the front of the carrier causing the carrier to pivot on the mounting pin and dump material through the separation of the the carrier and the blade at its bottom. Side plates of the carrier extend beyond the back of the blade in a shearing action to maintain self alignment. Quick separation of the carrier from the excavator blade is obtained by simply removing mounting pins on which the carrier pivots and using the backhoe to move the carrier conversion away from the excavator or backing the excavator away from the carrier.

Abstract: A backhoe-loader with a undercarriage resting on wheels and comprising at its front end a loader structure with a loader arm and a loading bucket and at the other end a superstructure revolving 360.degree. , a driver cab is mounted to one side of the superstructure and on the other side next to the driver cab there are provided power units and a mounting pad pivotable about a vertical shaft for the horizontal pivot shaft of an excavator boom. The boom is positionable in a raised state with the dipper arm collapsed and the implement in a forward-pointing rest position above the undercarriage and outside the field of view of the driver cab. A front mudguard is present in front of the mounting pad and functions as a rest for the implement, the loader structure is mounted asymmetrically relatively to the longitudinal center axis of the undercarriage on the cab side of the undercarriage, and the rest for the implement on the front mudguard is widened toward the middle of the undercarriage.
