Abstract
The invention refers to an apparatus for locking a converter tilting gear during a blasting operation, which apparatus is provided with a supplementary gear arrangement to facilitate counterrotation of pinions arranged in pairs versus the pivot pin gear wheel, so that the pinions may be locked and loosened by means of arresting brakes. The arrangement is such that the gear trains for the individual drive pinions can pivot in relation to the position of the pivot pin gear wheel in synchronized fashion to accommodate play between the cooperating gear teeth.
