A fully portable electric vacuum suction cup intended to lift, move, and place everything from tiles and drywall to furniture and large appliances.
The Grabo PLUS (Grab 220) features up to 170kg of grabbing force and can secure to almost any surface, enabling you to handle unwieldy loads quicker and more safely than ever before. All while minimizing the risk of damage to expensive materials.
Built-in Pressure gauge. Ideal for use on smooth & rough surfaces, even on rough paving slabs
Traditional suction cups are only capable of creating a good seal with flat, clean and airtight surfaces such as glass. However, Grabo’s unique seal allows the tool to adhere to rough, etched surfaces.
The maximum surface roughness which Grabo can attach to depends on the exact ‘profile roughness parameters’ (The geometry of peaks and valleys in the material) and is generally limited to an amplitude of about 2.5mm (0.1 inches). This capability allows Grabo to create a seal with the majority of patterned tiles, pavers and construction materials.
A porous surface is any surface that allows gas to flow through it. Many construction materials are porous to varying degrees. The most common porous construction materials are wood, concrete, rock, gypsum boards and many ceramics and tiles.
Standard “suction cups” can not hold porous materials for more than a few seconds, even if the surface is flat enough to create a seal. A vacuum cavity on top of a porous material will quickly fail as air seeps in through the material.
Grabo overcomes this and allows secure adhesion to these materials by constantly pumping out a large volume of air at a rate greater than the diffusion rate of air through the surface.
The physics behind the calculation of flow rates through different materials is both complex and interesting. The flow rate required from Grabo to keep a strong vacuum seal against a porous surface is generally described by a formula of generalized Murray’s law:
The flow rate is then multiplied by the surface area under the seal for a given pressure differential, which results in the flow rate and power requirement from Grabo’s internal electric pump.
However, as interesting as the engineering is, users of Grabo do not need to worry about science. All you need to know is the Grabo is designed to work well on some of the most common porous materials in the industry.Order before 1pm weekday for a next day pre-noon delivery (subject to t & c's) insured.
It is not advisable to use the Grabo on materials like slate which is foliated because, whilst a seal may be created on the top surface, the layers can separate causing the rest of the material to come away.
Do not use the Grabo on very thin or brittle surfaces including glass under 3mm thick, as the suction can cause the material to flex and break.
Do not use the Grabo on thin plastic sheet, rubber or other flexible materials. This is because the suction can flex the material up against the release valve that is operated by the red button, preventing release of the material.
Whilst the Grabo has very impressive capabilities, please test it before attempting to lift anything, to ensure you know its capacity on different materials you work with.Contractors must ensure that products are fit for purpose - if in doubt, please get in touch
