When Installing The Elevator, We Need To Pay Attention To The Relevant Precautions. Next, We Will Introduce The Preparation Before The Installation Of The Elevator And The Installation Of The Fence And Cage. Preparation Before Installation 1. Carefully Prepare Special Construction Scheme For Installation Construction, And Conduct Safety Technical Disclosure To Installation Personnel. 2. Make The Foundation According To The Foundation Plan, Pay Attention To The Alignment, Leveling And Alignment Points, And Ensure The Level Of The Foundation And The Use Requirements. 3. Keep The Access Road Of External Construction Elevator Smooth, And Have Enough Space For Parking Equipment. When The Auxiliary Installation Of The Crane Is Required, It Is Necessary To Fully Consider Whether The Site Environment Meets The Operating Conditions Of The Crane. 4. Ensure The Excellent Power Supply At The Installation Site, And Install A Separate Distribution Box. When The Distribution Box Is Used, The Electric Leakage Switch Must Meet The Requirements Of The Construction Elevator. If The Installed Construction Elevator Is Controlled By Frequency Conversion, It Should Be Adapted To The Frequency Converter When Selecting The Leakage Switch. Installation Of Fence And Cage 1. Clean The Foundation Surface And Install The Foundation Bolts. If The Installed Construction Elevator Is Installed On The Basement Floor, Pad Iron Must Be Used Under The Base Screw To Increase The Bearing Surface Of The Nut And The Floor To Reduce The Friction Between The Nut And The Floor; 2. A Steel Plate Gasket Of Different Thickness Is Padded Between The Base Plate And The Sill At The Anchor Bolt To Adjust The Verticality Of The Guide Rail Frame; 3. Install Three Standard Sections, And Measure The Perpendicularity Of The Guide Rail Frame With Theodolite To Ensure The Perpendicularity Of Each Main Pipe Of The Guide Rail Frame In Two Directions (1 / 1000); 4. After The Guide Rail Frame Is Adjusted To Be Vertical, Four Anchor Bolts Shall Be Pressed; 5. Adjust The Perpendicularity Of The Fence Door Frame As Above, And Compress The Other Foundation Bolts; 6. Install The Buffer Spring; 7. Connect The Other Half Of The Fence With The Front Half By Bolts; 8. As Above, Adjust The Verticality To Compress The Foundation Bolts, And Loosen The Brake On The Motor In The Cage. 9. Use A Crane To Lift The Cage From The Top Of The Standard Section To Make The Cage Accurately In Place; Cover The Two Cages On The Guide Rail Frame Respectively And Slowly Place Them On The Buffer Spring. 10. Reset The Brake; 11. Install The Service Section. The Maintenance Section Is Generally Installed In Section IV; 12. Install Two More Standard Sections. Check And Adjust The Perpendicularity Of The Guide Rail Frame With Theodolite To Make The Error In Two Mutually Perpendicular Directions Meet The Requirements Of Table 1.
