BOILER MODULE HOISTING METHOD, AND ELEVATING/LOWERING DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent the interference with an existing structure when hoisting a boiler module. SOLUTION: When a boiler module is hoisted from the ground by lifting jacks installed on a large beam of a steel frame and installed on the large beam, the boiler module is hoisted by arranging the front and rear lifting jacks which are transversely movable on the large beam. By alternately and transversely moving the front and rear lifting jacks, the hoisting module is hoisted to the large beam and installed while changing the hoisting position between the interference preventive position and the regulated hoisting position.
