Abstract: A continual digging, transporting, and loading accessory can handle material. The accessory is adapted for exchangeable attachment on earth or material moving equipment. The accessory includes a digger outwardly mounted on the earth or material moving equipment for digging the material. Also included is a transporter having an inward unloading end mounted on the earth or material moving equipment and an outward onloading end mounted adjacent to the digger for receiving and transporting the material dug by the digger. The transporter has a carrier for moving between the onloading end and the unloading end to carry the material. The accessory includes a loader having a loading end positioned to receive and transport away from the vehicle the material discharged from the unloading end of the transporter.

Abstract: A slit trencher can be mounted on a carrier machine which moves in a driving direction. The trencher includes a holder adapted to be mounted on the carrier machine. Also included is a boom mounted on this holder. The trencher has a circulating chain and a plurality of slit formers mounted on the circulating chain. The circulating chain mounted on the boom circulates thereon. This circulating chain is operable to perform work when circulating along a running direction. Each of the slit formers has a cutting edge slanted both with respect to the running direction of the chain and with respect to the driving direction of the carrier machine. These slit formers have a rear side and each includes a cover plate and a rear plate. The cover plate has a horizontal width sized to cover the width of the slit. This cover plate is slanted towards a direction opposite to the running direction of the circulator. The rear plate is mounted adjacent to the cover plate to block the rear side.

Abstract: An accessory for the boom of road working equipment has a frame arranged for attachment to the boom. The accessory also has a shaft rotatably mounted in the frame. Also included is a motor mounted on the frame for rotating the shaft. The accessory employs a rotary tool mounted on the shaft.

Abstract: Earth moving equipment for cutting into the earth employs a container having a forward opening. A holder is mounted in front of the container opening about in the middle thereof. A milling device is mounted on the holder for cutting into the earth. This milling device is positioned in front of the container for throwing cuttings into the container. The milling device includes right and left milling drums having respective axes subtending an obtuse angle with respect to each other. These milling drums each have a plurality of picks for cutting into the earth. The drums have a combined width exceeding that of the container so that the container can follow the milling device into locations cut out by said milling device. The milling drums are closely spaced to allow their picks to cut completely across their combined width without leaving an uncut region between the milling drums.
