The crushing wall is fastened to the conical body by means of a conical head screwed through the bushing and the upper spindle thread. For ease of removal and prevention of loosening, a split kerf is provided at the lower thread portion of the conical head, and the width is 10mm. When the conical head is tightened and the crushing wall reaches a sufficient fastening force, four M20 bolts are used to lock back. Buckle, which is the “first pass” lock. In the original design, a six-slot spline hole was cast in the plane of the conical head, and the six-tooth braking gear had a clearance fit (with a gap of 6 mm). The flat hole of the braking gear was also set on the flat shaft head at the upper part of the spindle. Two 150° circular brake pads and 6 M8 bolts to the brake gear. Prevent the brake gear from oscillating axially, that is, “secondary” anti-loosening.
