1. Equipment Unpacking and Inventory: Before installation, mechanical equipment must first be unpacked and inventoried to verify the quantity and quality of the supplied goods and to maintain proper records.

2. Foundation Layout: Installation reference lines are established based on the equipment layout drawing and relevant building axis and elevation lines. A common installation reference line should be marked for equipment that is interconnected or arranged in a specific sequence; standard reference markers should be embedded where necessary, and specific foundation location and elevation lines should be set out.

3. Equipment Foundation Inspection: This primarily involves checking the foundation's location, geometric dimensions, and concrete strength against design requirements. For certain heavy-duty equipment, a foundation pre-loading test is conducted prior to installation, while for others, foundation settlement monitoring is performed during the equipment's trial run.

4. Equipment Positioning: The equipment is safely hoisted onto the foundation and roughly positioned; this stage places high demands on lifting operations. For equipment delivered in disassembled components, the base must be positioned first.

5. Precision Inspection and Adjustment: Precision inspection and adjustment constitute a critical phase of the mechanical equipment installation project and serve as a key indicator of installation quality.

6. Equipment Securing: Most mechanical equipment requires anchoring to the foundation, a process known as secondary grouting. For disassembled equipment, the base must be positioned and secured before the rest of the assembly takes place.

7. Disassembly, Cleaning, and Assembly: Disassembly, cleaning, and assembly are required for equipment delivered in components and for integral equipment that has exceeded its rust-prevention storage period. Assembly proceeds from sub-assemblies to components, and finally to the complete unit; the main machine is assembled before the auxiliary equipment.

8. Lubrication and Oil Filling: This is essential for ensuring the normal operation of mechanical equipment. Lubrication circuits and points must be clean; lubricants must be selected appropriately and meet quality standards; and the correct quantities of oil and lubricants must be applied.

9. Adjustment and Trial Run: This is a crucial stage for comprehensively verifying the quality of both equipment manufacturing and installation. It involves multiple disciplines and personnel, requiring meticulous organization and unified command.

10. Project Acceptance: Upon successful completion of the equipment trial run, project acceptance procedures should be processed promptly.
