Fig. 438 shows another view of the same ropeway representing a long span over
a river. The ropeway passes obliquely over a bridge, and is supported by the trestles
on the opposite bank. The
safety net for the protection of
the bridge is also visible.
Fig. 439 represents a portion
of a ropeway erected in the Isle
of Elba for conveying ore from
the mines to the coast. At the

Fig. 440 illustrates a portion
of a ropeway executed for the

An interesting example of a
