|6.5.2 Checking the loads to the steel beams|
|The coil rests on two steel beams of 18 x 18 cm and a length of t = 500 cm with intermediate layers of timber dunnage for increasing the friction. The loaded length from the coil is r = 100 cm. With the extension of (t - r) = 400 cm and the load of 12 t, the diagram in Figure 17 provides the necessary section modulus of just over 390 cm³.
Each beam has a section modulus of 426 cm³ (Table 2). Also the extension of 400 cm is well within permissible limits of 480 cm in this case.
