Lifting magnets are electromagnets used to pick up metal objects, ranging from credit card size to double bed size. They are used in various industries, including construction and auto wrecking. Different types of lifting magnets are available, including scrap magnets and magnetic sweepers. Safety precautions must be taken when using high-power lifting magnets.
A lifting magnet is an electromagnet designed to pick up or lift metal objects. These magnets vary widely in size and can be as small as a credit card or as large as a double bed. Usually, larger lifting magnets are operated by hanging from a chain on a crane which is capable of dangling the magnet into the position needed to retrieve the desired object. This type of magnet can be used for a wide variety of purposes, including auto wrecking, construction, demolition, and cleanup.
There are many types of lifting magnets. The most common are designed to lift heavy metal objects weighing several tons. Others, sometimes called magnetic sweepers, help pick up debris such as nails, screws, and small bits of metal from construction site rubble. Using a magnet to retrieve scrap metal from a construction site can help prevent injury and damage to your vehicle’s tires.
A lifting magnet can also be called a recovery magnet. They are particularly useful in situations where another method of moving the metal object would be difficult, dangerous or expensive. These magnets can be dropped in dark places to pick up metal objects and debris from otherwise hard to reach places. These magnets are also used in underwater situations where metal recovery is required. These underwater magnets can be used to recover metal from a damaged submerged vessel such as a sunken ship or a wrecked oil well.
Larger and heavier lift magnets are often called scrap magnets. They can be used to lift large objects such as wrecked vehicles. Specially designed scrap magnets have the ability to lift large spools of wire without risking the spool unwinding or threading. Telescopic is when the cores of the line fall off the center of the spool. When a spool of thread telescopes, the heavy wire puts nearby people and objects at risk, and it is often difficult to rewind the thread after being telescoped.
A strong lifting magnet can be dangerous if not used properly by trained persons. For safety reasons, a high-power lifting magnet is always placed on the intended lifting object before it is switched on. Placing the magnet on the correct object before turning it on reduces the chances of damaging other nearby objects with an out-of-control lifting magnet.
