Abstract: A thrust grate, particularly a cooling or fire grate having an essentially horizontal sequence of two sets of grate plates alternatingly fixed and reciprocating forward and backward in linear alignment and vertically spaced from each other. Each set of plates has a rear portion extending in the direction of movement of the movable grate plates, an at least partially upward slanting front portion, and an inclined front.The front end of each plate overlaps the rear end of each following plate. The front ends of the fixed and reciprocating plates, each, are provided with a lip or nose, respectively, to move the material deposited on the sloped portions thereof.The angle of the sloped portion of the fixed grate plates is different from that of the movable grate plates.The rear portion of the plates with the smaller angle is positioned on a higher level than the rear portion of the plates with the larger angle slope.

Abstract: A thrust grate with several rows of grate plates, with each preceding plate of a row overlapping the next following plate of the following row has the rows of grate plates alternatingly fixed and reciprocating in the longitudinal direction of the grate. The fixed grate plates are rigidly mounted by means of a fastening device on grate plate supports, which are arranged transversely to the longitudinal direction of the grate. The fastening device has a support surface extending essentially parallel to the longitudinal direction of the plates, and transversely thereto a stop surface on the grate plate support and on each grate plate. The fastening device has also a traction element which holds the grate plate on the grate plate carrier.
