There are also two vertical posts between the lower element and the top element, working in compression. On the upper surface of the top element, working in compression, there are cushions (42, 46) with attachment holes (44, 45, 47, 49). ^ EFFECT: possibility of mounting trusses on side frame without possibility of their destruction when bogie is being used. ^ 22 cl, 5 dwg |
