Aluminum Alloy Heavy-Duty Glass Suction Cup | Premium Rubber Pad Vacuum Lifter Puller (Single & Double Claw) - Atradesen

Aluminum Alloy Heavy-Duty Glass Suction Cup Lifters (Single & Double Claw)

Handle heavy glass panels, smooth stone slabs, ceramic tiles, and sheet metal safely with our premium aluminum alloy glass suction cups, available at Atradesen.com. Engineered with a rugged, high-strength cast aluminum body and thick, high-grip rubber vacuum pads, these professional lifters provide powerful, reliable holding forces for glazier installations, stone relocation, and automotive dent pulling.

Featuring standard quick-release plastic hinge levers, these manual vacuum grippers allow you to establish a secure hold or release the suction instantly, protecting both your materials and your hands on the job site.

Two Heavy-Duty Configurations

• Single Claw Model (0.45kg): Features a compact, single-handed D-handle with an engraved "SINGLE JAW" profile. Equipped with one 12cm thick rubber suction cup, it delivers a rated horizontal lifting capacity of 50kg (110 lbs) and a vertical capacity of 30kg (66 lbs). Perfect for small to medium glass panes, glazed tiles, and bodywork dent pulling.
• Double Claw Model (0.90kg): Features an elongated, dual-hand grab bar connecting two independent 12cm suction heads. Delivering twice the holding power, it has a rated horizontal lifting capacity of 100kg (220 lbs) and a vertical capacity of 60kg (132 lbs). Ideal for transporting heavy, large-format glass panels, solar panels, and smooth stone countertops.

⚠️ Operating & Safety Guidelines

To ensure absolute safety and prevent accidental slips, please adhere to these guidelines:

• Ensure Flat & Clean Surfaces: Suction cups rely on a hermetic vacuum seal. They are only suitable for non-porous, smooth, flat, dry, and clean surfaces such as polished glass, glazed tiles, polished granite, sheet metal, and rigid plastics. Dirt, dust, moisture, or micro-cracks will disrupt the vacuum and cause slips.
• How to Lock: Place the suction cup firmly onto the target surface, press down, and flip the quick-release plastic hinge levers. This extracts the air and locks the high-grip rubber pad in place.
• How to Release Safely: To release, simply flip the hinge levers back up. The rubber pad will automatically release its seal. Do not attempt to slide or pry the rubber pad off the surface with sharp metal tools while locked.

Frequently Asked Questions (FAQ)

Q: Why is the vertical lifting capacity lower than the horizontal capacity?

A: When lifting horizontally, the load is pulled perpendicular to the face of the suction cup, utilizing the maximum direct vacuum holding force. When lifting vertically, the load pulls parallel to the face of the cup, causing shear force. Gravity and friction play a significant role here, which is why a safety margin is added, reducing the vertical rating.

Q: How do I maintain the rubber suction pads to keep their powerful suction?

A: Always store the suction cups in a cool, dry place when not in use. Regularly clean the rubber pads with mild soapy water and a soft cloth to remove oil, dust, and grease. Never expose them to harsh solvents or store them under heavy loads that could deform the rubber lips.
