摘要： PROBLEM TO BE SOLVED: To provide a system and a method for assembling a stator coil with a small number of workers as a light work while avoiding the dangerous work. SOLUTION: A stator frame 1 is turned to the fixing slot position of a stator coil 4 by means of rotating units 5a, 5b and the stator coil 4 is mounted on a truck section 30 using a permanent scaffold 7a before the truck section 30 is guided on a rail section 50 to the inlet of stator frame 1. The truck section 30 then departs the rail section 50 and travels through the stator frame 1 to deliver the mounting stator coil 4 to a slot inserting section where the stator coil 4 is inserted into the slot of a stator core and fixed in place.

摘要： PURPOSE:To mass-produce a tube panel of high quality in a small space. CONSTITUTION:A plurality of intermediate lattices 3 each having a number of apertures 3a are positioned. Inserted into these intermediate lattices 3 are heat transfer tubes 1 having been subjected to edge preparation. Then short-pass prevention plates 4 are mounted to make an integral tube group. The tube group is inverted 90 degrees to assume a position, in which a length of a header 2 is made vertical. Then while remaining in such position, an operation is conducted which includes welding of the header 2 and the heat transfer tubes 1, X-ray inspection, stress relieving annealing, non-destructive inspection, visual inspection and dimensional inspection of the weld. Finally, a tube panel A is subjected to pressure test with lengths of the heat transfer tubes 1 positioned in a vertical direction.
