The design concept of the scissor lift platform is as follows:

1. Determine the basic structure: Set appropriate dimensions and weights according to the requirements. Consider using high-strength materials such as aluminum alloy to reduce the total weight. To ensure stability, it is necessary to set up a fixed base and take measures to prevent tipping. 2. Design a scissor type lifting and shrinking mechanism: Based on the requirements for adjusting the working height and the workspace, design the structure to ensure safety, stability, and ease of operation; 3. Choose power source: You can choose an electric motor as the power system for ascending and descending; 4. Control method: The platform can be raised and lowered by handheld switches or remote controls. 5. Safety protection devices: must be installed in place to ensure the safety of personnel and equipment. 6. Design of the electrical control part. 7. Conduct testing, evaluation, optimization and improvement steps. 8. Ensure that the product complies with ergonomic principles. 9. Fatigue tests must be conducted on some key load-bearing components to verify their reliability.
