Abstract: In a lifting gear comprising a lifting cable and two blocks, e.g. the upper trolley block and the lower hook block, respectively, of a hoisting crane, the number of cable parts, in which the lower block is hanging, is changed, in order to increase or decrease the lifting capacity, by means of a cable catching means being arranged on the lower block, which catching means is capable of catching (or disengaging) a cable part running horizontally in the upper block, which cable part is pulled down as two further parts with the catching means and at ground level laid under a further rope pulley of the lower block. Reblocking to fewer cable parts is carried out in the reverse order.
