Diameter of extended part of reinforcing ribs makes, at least, 50 mm. Inner cavity of solebar, at zone of connection between inclined belt bottom walls, vertical walls of jaw guides and horizontal above-journal box section, has extra reinforcing ribs consisting of circular transitions of horizontal above-journal box section inner angles. Said extra ribs are arranged parallel with lower walls of inclined belts and in different planes with respect to inclined belt lower walls. Length of said ribs makes at least 60 mm.EFFECT: higher reliability.2 cl, 3 dwg |
