METHOD FOR PULLING UP SAFELY A GENERATOR STATOR WITHOUT INTERFERENCE WITH OTHER CONSTRUCTIONS AFTER INSTALLING A LARGE GANTRY IN AN EXISTING BUILDING

摘要

PURPOSE: A pull-up method of a generator stator is provided to carry out other works at the same time by pulling up the stator in the cross direction without interfering an upper part, to secure safety by shortening the distance, and to reduce the work time. CONSTITUTION: In a pull-up method, a pull-up device is composed of a support disposed at the lower part in a building(10); a lower part and an upper par(40) arranged at the support position; and a jack unit positioned at the ceiling to hold and salvage the stator at the constant distance. A generator stator(30) is pulled by installing a rail(70) across the installation direction of the upper part mounted in the building. The generator stator does not pass through the upper part and accordingly the stator is salvaged without interference.
