Dimensions of the cabins, load and speed are selected so as to be close to the value of the system Renard R10. French military engineer Colonel Charlse Renard in 1870 proposed a set of priority numbers for use in the metric system. The system was adopted in 1952 as the international standard ISO 3. When designing the lifts are recommended to use the following values
Load bearing capacity of the lift (kg) : 320, 450, 630, 800, 1000, 1275, 1600, 1800, 2000, 2500 The speed of the lift (m/s) : 0,4, 0,63, 1,0, 1,6, 2,0, 2,5, 3,0, 3,5, 4,0, 5,0, 6,0 |
