"Be careful!" this is the response we got as kids from adults when we handled an object made of glass or ceramic. Even in our grown stage, there is still a certain reverence when using such objects. We handle them with utmost care as we would an egg for various reasons; for our safety, to avoid any damage and preservation.
How would you handle a phone made of glass, a table mirror, or a glass window? With every fiber of attention within you.
No one deliberately runs into a glass door or fiddles with broken glass because then it will have a negative physical effect.
In the past, when an engineer wanted to lift and fit a glass object, he had to use his hands which led to the work done but most times at the expense of workers' causalities and injuries. It was not the safest option, but it was all we had until the suction cup lifter was founded and patented in 1929. The lifter is adapted for picking up sheet material such as glass, metal, concrete, etc.
WHAT IS A SUCTION CUP LIFTER?
It is a form of suction cup used for commercial and industrial lifting operations. The construction industry is often used to move large and smooth objects such as glass panes and fixtures like countertops, marble slabs, floor tiles, etc. It is commonly hand-operated and can also be operated on a hoist. It uses the same operating mechanism as the suction cup, maintaining a vacuum between the surface to be lifted and a flexible material that is mostly rubber. It traps the air in the rubber covers, and when the cup is pushed against the surface, the air inside is moved outside, creating a vacuum and maintaining a firm grip on the surface.
It was a breakthrough in the invention, but the suction cup lifter still had significant limitations. Some of them are: the vacuum is induced manually by the winding of a knob or the cup handle. Also, workers will usually be strained after lifting because of the consistent bending or squatting to pick up sheets despite using the lifter.
GRABO; AN IMPROVED WAY OF LIFTING
Nemo Power Tools saw this limitation of the regular vacuum lifters. They improved on it by designing the GRABO, an electronic suction cup lifter for glass that automatically induces the vacuum between the surface and its rubber seal.
GRABO is made with lightweight plastic, which makes it portable to handle. It has a strong vacuum pump that works in conjunction with its rubber seal.
To lift a slab of material, all you have to do is turn on your GRABO unit by pressing the green button and placing it on the surface. Once the pump is activated, it creates a strong suction and firmly grips the surface.
You can turn off the pump while moving the object, but it is advised you keep it activated to ensure maximum holding capacity if there is an air leak due to a foreign object or dirt. This avoids injury as the continuous vacuum pump action maintains constant pressure, holding the material well. Once you are done moving the object, press the red button, this releases the vacuum, and the GRABO loses its grip on the object, and you can move further to the next object. Work speed is enhanced, and productivity increases.
GRABO is powered by a strong rechargeable and replaceable lithium-ion battery. It can run for 900 ON-OFF cycles of 10 seconds, making a total of 90 minutes. It also has a removable rubber seal that protects the mechanical pressure gauge, a fitting handle, and four lifting lugs placed on the sides of the handle.
It comes in a complete kit comprising one GRABO tool with an inbuilt mechanical pressure gauge, one multi-socket charger, one extra seal (an addition to the pre-installed one), an extra battery, a fabric carry bag, and a manual on how to operate the device.
Also, they eliminated the limitation of pains and strains of workers caused by the manual lifters by designing a complimentary attachment to the GRABO. One of which is the Erguo S1 attachment. This is where the four lifting lugs at the sides of the suction lifter come into play. It is attached to the Erguo S1 using screws. With this improvement, professionals don't have to bend to pick up the objects, and it is safe and easy to use.
Other accessories are being worked on by the GRABO team, which will be revealed in due time.
WHY IS GRABO THE BEST SUCTION LIFTER FOR GLASS?
Using the GRABO ensures a safer and neater work experience. Time is used judiciously, and more work is done in little time. The constant pressure maintained by the continuous action of the vacuum pump secures a firm grip on the object's surface; therefore, there is a reduced risk of injury.
The suction lifter comes in three models, for now, all of which can be used to lift glass, the Nemo GRABO wielding a maximum weight capacity of 375Lbs(170kg) for perpendicular hold and 265Lbs (120kg) for parallel hold, the GRABO Pro-lifter 20 which can automatically calculate the weight of the object and has the same carrying capacity as the Nemo GRABO and finally the GRABO H which is used for smaller weights and menial jobs.
No more gory incidents or hazards at work. GRABO is changing the way work is done one tool at a time.
