Products and Technologies
Vacuum Tube Lifters
Vacuum tube lifters use a powered vacuum system and a flexible lifting tube to raise and lower loads under operator control. Cowest’s SKG-series equipment is described for handling bags, cartons, casks, wood panels, sheets, metal products, and glazing materials, with models available for loads of up to approximately 120 kilograms.
Typical technical features include:
- Vacuum generation through an electric pump or comparable suction system
- A flexible lifting tube that changes length according to vacuum pressure
- Control handles for raising, lowering, and positioning loads
- Interchangeable suction attachments adapted to different surfaces
- Stainless-steel construction for applications in food and chemical environments
- Configurations tailored to palletizing height and load geometry
These systems are particularly suited to repetitive lifting, palletizing, depalletizing, and short-distance transfer. Their usefulness depends on the load’s surface characteristics, permeability, weight distribution, and available vacuum seal.
Glass and Panel Lifters
Cowest also supplies vacuum lifters for glass, stone, metal sheets, composite panels, and other relatively smooth materials. Such systems generally use multiple suction cups connected to a vacuum circuit, allowing operators to move large panels while maintaining controlled contact with the workpiece.
Applications include:
- Architectural glazing
- Curtain-wall installation
- Window and door manufacturing
- Glass processing and fabrication
- Handling of sandwich panels and sheet materials
- Construction-site lifting and positioning
The engineering requirements for these machines include suction-cup layout, vacuum monitoring, load balance, battery capacity, wheel configuration, lifting height, and the ability to operate on indoor or outdoor surfaces.
Glazing Robots
Glazing robots combine vacuum gripping with powered movement and controlled positioning. They are designed to reduce the physical demands of installing large glass panels and to improve handling precision in construction and façade work.
Depending on configuration, such systems may incorporate:
- Powered travel and steering
- Hydraulic or electric lifting
- Tilt and rotation functions
- Remote or assisted controls
- Vacuum-pressure monitoring
- Compact chassis designs for confined installation areas
Their value is greatest where panels are heavy, fragile, oversized, or difficult to position manually.
Heavy-Duty Vacuum Lifters
Cowest’s product portfolio also includes larger lifting machines for substantial glass and panel loads. Exhibition and company-related materials describe equipment capable of handling loads ranging from compact units to heavy-duty systems designed for industrial or construction applications.
For heavy-load equipment, performance depends on:
- Rated lifting capacity
- Number and arrangement of suction cups
- Surface flatness and cleanliness
- Vacuum redundancy and warning systems
- Battery or power-source endurance
- Stability during travel and elevation
- Compliance with applicable workplace-safety requirements
A product listing for a stainless-steel SKG-series lifter identifies applications in food and chemical industries and describes compatibility with bags, cartons, drums, sheets, metal, and glazing materials.
