Abstract

In the coking of coking coal according to the compression process the coking coal is compressed by power hammers before its introduction into the coke oven, whereby these hammers having elongated hammer rods are lifted by means of driven cam disks acting upon them by sections, and then released to drop. The cam shafts bearing the cam disks, corresponding to the number of power-hammer rods, are individually pivoted. Their bearing points on both sides of the hammer rods are movable synchronously and in the same direction and are uniformly actuated by a hydraulic system. Thereby, the individual cam shafts can be driven and pressed against the individual power-hammer rods, according to given data. An even and uniform lifting of all rods and power hammers is achieved by that.
