Tower superstructure and method for erecting a tower superstructure

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.

1 - 10 . (canceled) 
     
     
         11 . A tower superstructure of a ropeway transport installation comprising:
 a bar designed to be fixed to a tower;   a catwalk;   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.   
     
     
         12 . The tower superstructure of a ropeway transport installation according to  claim 11  wherein the insertion direction is a vertical direction. 
     
     
         13 . The tower superstructure of a ropeway transport installation according to  claim 11  wherein the hole has a decreasing cross-section in a direction opposite from the insertion direction. 
     
     
         14 . 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. 
     
     
         15 . The tower superstructure of a ropeway transport installation according to  claim 14  wherein, in the unlatched position, the catwalk is removable with respect to the bar 
     
     
         16 . The tower superstructure of a ropeway transport installation according to  claim 11  comprising at least one adjustment part configured to adjust the insertion of the hook with respect to the hole in the insertion direction, the adjustment part pressing on at least one of the catwalk and the bar. 
     
     
         17 . The tower superstructure of a ropeway transport installation according to  claim 16  wherein the adjustment part comprises at least one screw fixed to the catwalk and pressing on the bar or at least one screw fixed to the bar and pressing on the catwalk. 
     
     
         18 . The tower superstructure of a ropeway transport installation according to  claim 16  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 and in the latched position, a wall defining the hole is separated from a wall defining the hook. 
     
     
         19 . A method for erecting a tower superstructure of a ropeway transport installation comprising the following steps:
 providing a tower body and a tower superstructure according to claim  1 , the bar being fixed to the tower body;   inserting the hook in the hole and moving the catwalk downwards to make the catwalk slide with respect to the bar until catwalk is supported by the bar, the insertion direction being vertical and directed downwards.   
     
     
         20 . A method for erecting a tower superstructure of a ropeway transport installation comprising the follow steps:
 providing a tower body and a tower superstructure according to claim  18 , the bar being fixed to the tower body;   inserting the hook in the hole and moving the catwalk downwards to make the catwalk slide with respect to the bar until catwalk is supported by the bar, the insertion direction being vertical and directed downwards, and   further comprising vertical adjustment of the catwalk with respect to the bar followed by latching of the position of the catwalk with respect to the bar, a wall defining the hole being separated from the wall defining the hook in the insertion direction.
