Suction cups of different structures and specifications vary greatly in applicable materials, workpiece sizes, working environments and handling conditions. To avoid unstable adsorption, falling off and low working efficiency caused by improper selection, we classify and match full-range products including manual suction cups and electric vacuum suction lifters for common working scenarios such as small building materials, home decoration glass, large heavy-duty panels and high-altitude curtain wall hoisting. This comparison table clearly defines the applicable scope of each suction cup, accurately meets the usage requirements of different loads, materials and working environments, and provides a standardized and efficient reference for suction cup selection in home decoration construction, building material handling, curtain wall engineering and other scenarios, ensuring the safety and stability of handling and hoisting operations.
Suction Cup Type | Safe Working Load | Application Scenario |
Single Suction Cup | ≤50kg | Short distance indoor handling of small size glass, mirrors and tiles |
Double Suction Cups | 50 80kg | Tempered glass for doors & windows, widely used in home decoration |
Triple Suction Cups | 80 120kg | Large floor to ceiling windows, big format sintered stone slabs, heavy duty glass |
Electric Suction Cups | 100 1000kg+ | Curtain walls, large overhead panels, long time lifting operations |
⚠️ Safety Reminders
1. This selection reference table is for guidance only and shall not be used as the sole load bearing criterion.
2. Always inspect the suction pad for damage or air leakage before actual operation.
3. Operate strictly within the rated load capacity. Over loading for workpiece handling is prohibited.
4. Fall protection measures must be implemented during high altitude lifting work.
5. Do NOT use suction cups on damp, dusty, uneven or porous air permeable surfaces, which will reduce adsorption force.
6. Never stand underneath the workpiece during transportation; keep clear of potential falling hazard zones.
