PROBLEM TO BE SOLVED: To increase the safety of a worker and a working efficiency when parts are suspended and assembled. SOLUTION: This human engineering quadrail device comprises a first pathways 11 formed of rails 12, 14 and a second pathways 13 formed of rails 16, 18 fitted to a static structure such as a ceiling. A total of five carriages 20, 22, 24, 26, 28 are guided by these rails. The carriages hold the parts such as the core module 84 of a gas turbine engine and are movable horizontally along the rails. The height positions of the parts of the carriages and the attitudes of the carriages in the rotating directions are variably changed by an adjustable arm. The worker easily assemblies the parts by adjusting the spacial positions of the parts by the carriages. COPYRIGHT: (C)2007,JPO&INPIT |
