Hoist Lifting Crane with Suction Cup
Core Components
The Hoist/Crane: Usually an overhead bridge crane or a jib crane that provides the horizontal movement (X-Y axis).
Vacuum Generator: Either an electric pump or a Venturi ejector (which converts compressed air into a vacuum).
Suction Pads/Cups: Made of nitrile, silicone, or VITON depending on the temperature and oiliness of the material.
Operating Handle: Often includes “Up/Down” controls for the hoist and a “Grip/Release” trigger for the suction
Safety Mechanisms
Since the “grip” is invisible, these systems have strict safety features:
Vacuum Reservoir: A “buffer” tank that holds enough vacuum to keep the load attached for several minutes even if the power fails.
Non-Return Valve: Prevents air from rushing back into the suction cups if the pump stops.
Vacuum Gauge/Alarms: A visual “Green/Red” indicator or audible siren that warns the operator if the suction level is too low to lift safely.
Two-Button Release: Often requires the operator to use both hands to release a load, preventing accidental drops.
Common Applications
Glass Industry: Moving “Jumbo” sheets of glass or installing windows in skyscrapers.
Sheet Metal Fabrication: Loading laser cutters or CNC punch presses.
Packaging/Logistics: Palletizing cardboard boxes or 25kg bags of flour/chemicals.
Furniture: Moving large MDF or plywood panels through a wood shop
