Rollers. The most rational form of rolling bodies for the purpose of moving buildings should be recognized as cylindrical rinks.
For the most part, rollers made of steel or cast iron with a diameter of 5 to 14 cm are used. With small pressure, hollow cylinders can be used instead of solid cylinders, for example, steam -wire steel pipes. The rollers are calculated for crushing in the places of their contact with the rolling surface according to the formulas of Hertz, and two cases of contacting can be found: 1) when rolling the rink along the rails and 2) when rolling the roller on the plane.
