Replacement of the door supports the import of machine bearings
1. Collating used construction tools, and show the construction area. Once again to check the situation in various parts of the construction, removal of debris around the door.
2. With floating crane gantry crane demolished parts of the upper rotary support after the replacement of imported bearings under way, the demolition of parts of many tools used by many to be required for construction of more than 10 staff working hours to 7 working days, of which three requires the use of floating crane working days.
3. Operated jack who obey the command password, and mutual coordination, and strength, making part of the door was slowly rotating machine jacking uniform. Rotating wind closely with sales, marketing synchronous wind down spin must be tightened up to force.
4. Out of the damaged bearing raceway imports. The center line of bearing support tube and the lower part of the next junction permeability easily found the site of permeability needed to repair welding.
5. The rolling bearing ring Road and the height of roller 140mm, from the construction of the various factors considered, the top or as a maximum height of 120mm, leaving 20mm for support to maintain stability after jacking.
6. Slope suffered under the column to the top of the vertical lift for the 300kN, which is subject to pressure for the next column and roof slope stent or welding on the contact surface to strengthen the board, in order to increase its local
