Abstract: There is described a crushing plant and a method for controlling the same. The crushing plant includes a crusher (1) and a feeding arrangement (3), and is driven by a diesel engine (13). A load value related to the diesel engine is retrieved e.g. by means of a J1939 interface. If the retrieved value exceeds a predetermined threshold value, the control loop of the feeding arrangement (3) is altered. Thereby it can be avoided that the diesel engine (13) stalls, such that continuous operation of the crushing plant may be ensured.

The wall section is elastically flexible and, in the mounted state, bent toward the end surface of the protuberance by the contractive force of the fastening element.

Abstract: A method for manufacturing a component having at least one internal cavity includes the step of providing a core element of metallic material that includes at least one cavity having a first opening covered by a cover element with a first and second side. A form partially surrounds the core element and cover element. The form is filled with metallic filling material and heated in a heating chamber that is pressurized with gas for a predetermined time period at a predetermined temperature and a predetermined isostatic pressure, so that a metallurgical bond is achieved between the core element, cover element and metallic filling material. The core element is arranged such that, after filling the form with metallic filling material, the second side of the cover element is covered with metallic filling material so that the cavity during heating is pressurized to the predetermined isostatic pressure.

Abstract: A road grading pick includes a cutting head, a shank, a shoulder at a transition between the cutting head and the shank, and a polygonal-shaped washer or an oval-shaped washer. The shank is positioned in an opening of the washer to position the washer along a longitudinal length of the shank between a rearward end of the shank and the rearward facing surface of the shoulder. In a preinstalled position, the washer compresses a friction retainer on the shank of the road grading pick to facilitate seating of the road grading pick in a blade of a road grading apparatus. In an installed position on an adapter board for a moldboard of road grading equipment, the friction retainer is no longer in the opening of the washer and the washer prevents washer rotation and shields an underlying mounting surface while allowing rotation of the road grading pick.
