Abstract
A tower superstructure of a ropeway transport installation includes a bar and a catwalk. A first fixing part is fixed to the bar and a second fixing part is fixed to the catwalk. The first fixing part is a hook. The second fixing part defines a hole receiving the hook. The hook defines a downward vertical insertion direction. The hook and hole are able to sink into one another in the insertion direction until the catwalk is in abutment against the bar. The hook defines a decreasing cross-section in the insertion direction up to the position where the catwalk is in abutment to move the catwalk and bar towards one another.

- a first fixing part fixed to the bar and a second fixing part fixed to the catwalk, one of the first fixing part and the second fixing part being a hook and the other of the first fixing part and the second fixing part having a hole designed to receive the hook, the hook defining an insertion direction extending from a top of the hook to the bottom of the hook;
- wherein the hook and the hole are able to sink into one another in the insertion direction until the catwalk is in abutment against the bar;
- and
- wherein the hook defines a decreasing cross-section in the insertion direction from the top of the opening to the position where the catwalk is in abutment to move the catwalk and bar towards one another.
The tower superstructure of a ropeway transport installation according to claim 1 comprising at least one latch presenting a latched position wherein the catwalk is assembled fixedly with respect to the bar and an unlatched position wherein the catwalk is assembled movable with respect to the bar.
