  • the upper end of the ladder comprises curved branches 216 and 217 in the form of a hoop with a part 218 substantially extending the corresponding amount 211, a part 219 substantially perpendicular to the part 218 and an end part 221 substantially parallel to the amount 211.
  • the upper part of the ladder can be obtained during the manufacture of the ladder itself, i.e. bars and uprights, by following, during manufacture, the traction device and the mandrels a circuit corresponding configuration as shown in Figure 22.
  • Such a scale can be used with particular advantages by firefighters.
