Earth conductor for earthing systems of electrostatic separator, consisting of an electrically conductive core with a plastic or rubber sheath. In order to prevent the passage of liquid, the earth conductor consists of two conductor parts, the conductor parts are connected via a liquid-tight graphite piece, to which sections of the conductor parts are fixed, and the graphite piece and the sections of the conductor parts are embedded in a plastic body.

A multifunctional, self-contained towable backhoe apparatus adapted for direct over-the-road trailering by a towing vehicle, has a support frame having a front and a rear, and a trailering hitch attached to the front. Wheels support the frame at the front and the rear. The rear wheels can function as drive wheels. A backfill blade is movably attached to the rear of the frame. An articulated arm assembly is pivotably mounted on the rear of the frame. A stabilizer with a street pad, a spade, or bo...

In a method for producing and widening ground bores or for the destructive replacement of buried lines with the aid of a tool arranged at the end of a rod driven by a boring device, the rod is built up from individual sections which are to be connected to one another in a machine excavation (staring excavation). In order to allow the use even of rod sections whose length is equal or almost equal to the diameter of the machine excavation, the boring device, prior to the introduction of a new rod ...

A control device for earth moving equipment comprising a bucket pivotal about a bucket pivot between a closed position and an open position, a thumb pivotal about a thumb pivot between a first position and a second position, wherein the thumb pivot is separate from the bucket pivot, and an extension plate fixedly attached to the bucket and attached to the thumb pivot, wherein rotation of the bucket urges the thumb pivot to rotate around the bucket pivot and urges the thumb to move. A retrofittin...

A radiator for earth moving machines connected to the engine of the earth moving machine and comprising first connecting means that pivotally fasten the radiator to the frame, in such a way that the radiator can rotate about its own lower edge from a closed position in which it is approached to the frame to an open position in which it is in part moved away from the frame. The first connecting means comprise a plurality of support elements each integrally fastened to the frame in correspondence ...

An earth boring bit for boring a hole having a predetermined depth into the earth. The earth boring bit includes a cylindrical drum for being mounted for rotation on the end of a boom of a mobile machine and connected to and rotated by a power supply mounted on the boom. The drum includes an exterior for defining the diameter of the hole being bored and an interior adapted for receiving upturned earth therein as the hole is being bored. A plate is carried by the drum adjacent a lower end thereof...
