The invention relates to a mechanism for remotely adjusting the magnitude of the stroke/amplitude of the springs within spring boxes of the hammer vibration insulators in the forging rooms, without direct man intervention into the space of the foundation pit. The claimed mechanism which drives the adjustment screw () may comprise a gear rack () with the related hydraulic group and a linear hydraulic motor () or a rotary hydraulic motor () which drives a pinion (), integral with its shaft and intermeshed with a gear rack, or by driving the gear rack () by means of an electrical step motor () with a pinion (), mounted on its shaft, or by driving a gear rack () by means of a linear motor (), or the adjusting of the screw () is achieved by means of a worm gear () - screw () mechanism driven by a rotary electric or hydraulic motor (). |
