Mountain crossing device

Abstract

[Problem] To provide a mountain trestle with a resin traveling beam possessing the required strength and rigidity characteristics. [Solution] To provide a mountain trestle (10) with a traveling beam (12) for mounting a hanging device (100) for holding a suspended object (M). The traveling beam (12) of the mountain trestle (10) comprises a laminated structure (LC) having multiple composite resin layers (L1, L2). Furthermore, the laminated structure (LC) comprises: a first composite resin layer (L1) with higher strength and rigidity in the direction of the suspended load acting when the hanging device (100) is installed than in other directions, and a second composite resin layer (L2) with higher strength and rigidity in other directions than the first composite resin layer (L1).
