What Is a Suction Lifter?
A suction lifter is a device that uses the suction properties of rubber or other materials to adhere temporarily to an object.
Suction lifters can be used to suction heavy objects without handles, such as refrigerators and furniture, to make them easier to carry. In the home, they are useful for moving.
One-touch suction lifters can lift a weight of about 25 kg, even for small objects. They are equipped with a vacuum pump, have even stronger suction, and some products can lift up to 200 kg.
Uses of Suction Lifters
Since suction lifters can be attached to flat surfaces, they are used to transporting heavy and difficult-to-carry objects. Since the suction lifter has a handle, it can be attached to a position that is comfortable for the user to hold and stabilize the object.
Glass and other large objects can be easily carried by attaching suction lifters. They can also be used for furniture, refrigerators, machinery, metal plates, and other objects with smooth surfaces.
Because of its uneven surface, a suction lifter cannot be attached to cardboard, cloth, etc.
Principle of Suction Lifters
Suction lifters consist mainly of a handle made of aluminum or ABS and a rubber pad. The circular rubber pad is placed in flat contact with the target surface. By operating a lever or piston, air is sucked in to reduce the pressure, resulting in suction.
Products with a vacuum pump have stronger suction. The maximum adsorption capacity varies depending on the product, so check before use.
There are two types: a double type with two suction lifters and a single type with one suction lifter, with the double type having a larger maximum suction capacity.
If the surface of the pad is covered with dust, oil, or scratches, the adsorption capacity will decrease. If the rubber is deteriorated, the adsorption capacity will decrease, so the rubber pad should be replaced and maintained periodically.
There are also suction lifters that use porous carbon material in the suction area to adhere to large glass pieces. Large glass is adsorbed by sucking it up from the outside of the porous carbon with a vacuum pump to reduce the pressure. Porous carbon has holes evenly spaced, so that there is no bias in the adsorption force and a wide range of adsorption can be achieved in a stable manner.
