Push-grating cooler for cooling hot material

摘要

In order to ensure, especially in the case of large wide push-grating coolers, that the push-frame bearing with parallel guidance of the grating plates is guaranteed as far as possible without alteration of the gap width between the moving and the stationary grating plates, and without having to accept beneath the grating surface the wear parts present there hitherto, such as flanged rollers or other rolling bodies, it is proposed according to the invention that the push frame (15) be fixed on rigid bearers (18) which are arranged transversely to the cooler longitudinal axis and the ends of which are mounted on linear rolling bearings (19, 20) supported on the lower side walls (12) of the grating cooler. <IMAGE>
