How does a lifting electromagnet work?
Different mechanisms that make them suitable for specific applications.
An electromagnet is a piece of construction equipment designed to generate a magnetic field
and is often used for lifting, picking up and handling ferrous materials such as steel plates or scrap. Lifting magnets can be divided into three categories: hydraulic magnets
, electric magnets
or battery-powered electromagnets
. At the basis of their operation there are different mechanisms that make them suitable for specific applications.
In order to function, hydraulic lifting magnets
must be connected to the hydraulic system
of the machine to which they are installed. They do not require any electrical connection
, which makes them extremely versatile and they can also be used in remote areas. This type of magnet is connected through pipes from the machine to the generator
. When the oil of the machine flows, the magnet becomes magnetised; when the flow is interrupted, the demagnetisation occurs. These magnets are used for collecting ferrous materials in demolition and recycling sites as well as in scrap yards. Due to their size, they are often applied to heavy machinery such as excavators
is a magnetic device consisting of a ferromagnetic core
(usually made of mild iron) on which coils of electrical copper wire
are wound. Those products use mains electricity to power the coils it contains and from which the magnetic field is generated.
The battery powered electromagnetic lifters are magnets powered by a battery
which is installed on the machine
. Therefore, their operation is closely dependent on the batteries from which they are powered. There are also magnets with built-in battery
, which are independent, practical and versatile pieces of equipment that do not require any external power supply. They can be controlled through a radio remote control
and, thanks to their programmable electronics, can be used with various magnetisation profiles
. They are used in various sectors, such as construction and scrapping, and are designed to collect and move even small ferrous materials
Atib lifting magnets
Our magnets are the result of Atib group's decades of experience in the industrial and electronic sectors and offer a wide choice for the most diverse requirements. Each magnet can also be customised to suit the specific needs of each construction site
, demolition site
and recycling site
. Atib's hydraulic magnets can be equipped with teeth
to facilitate the handling and removal of scrap metal, with a chain
or with a plate for quick coupling
without any manual intervention by an operator. Low-voltage
or built-in battery-powered circular magnets
are also available and are extremely versatile.
