When the man conveyors 3 and 4 are installed by the latter method, first, two completed products assembled at the manufacturing factory are transported to the site. Thereafter, for example, the man conveyor 3 is lifted and installed at an installation position using a crane, a chain block or the like (not shown). Thereafter, as shown in FIG. 10, the remaining man conveyor 4 is also lifted using a crane, a chain block, etc., and installed at the installation position.
[0009]
[Problems to be solved by the invention]
In the conventional man conveyors 3 and 4 configured as described above, since the end in the width direction of the outer deck board 12 protrudes outward in the width direction from the truss 7, one man conveyor as shown in FIG. When the other man conveyor 4 is lifted after installing 3, the adjacent outer deck boards 12 collide with each other as shown in FIG. 11, for example, and the outer deck board 12 is deformed or damaged as shown in FIG. There was a thing. Further, when such a problem occurs, it is necessary to replace the outer deck board 12 at the site, which causes problems such as an increase in production cost and a decrease in installation work efficiency.
[0010]
