| Substructio ferrea supra memorata ex simplici est unilateralis; si aliam methodum connexionis requiris, sumptus materiae adde! Pro dimensionibus externis ab emptore datis, motor domesticus vel importatus temere eligi potest. Additio fulcri rotatorii vel mechanismi rotatorii, articulationis centralis rotatoriae, etc. Ferreae semitae trabibus gummi poni possunt ad superficiem viae protegendam. | |||||||
