Structural characteristics
• Ultra-high load capacity: usually designed to bear 2-10 tons, special customized models can reach more than 20 tons
• Rigid structure: box girder structure or reinforced rib design, strong anti-deformation ability
• Modular design: can be used in combination with countertops of different sizes, with strong scalability
Material technology
• High-quality steel: generally Q235B, Q345B or higher grade structural steel
• Anti-deformation treatment: through stress relief process, to ensure long-term use without deformation
• Surface treatment: spray anti-rust primer and high temperature resistant topcoat after sandblasting and rust removal

Factors to Consider
1. Load requirements: including workpiece weight, fixture weight, and operator weight
2. Working environment: consider workshop floor conditions, space constraints, etc
3. Function expansion: whether you need to move, lift, or other special functions
4. Accuracy requirements: requirements for platform stability for different grades of welding operations
Maintenance points
• Regularly check the fastening of structural connectors
• Avoid local overload use
Periodic level calibration
• Damage to the surface coating should be repaired in time
