Magnetkrans

Magnetkrans is a type of crane used in material handling and heavy construction, particularly in Norway and other Scandinavian countries. The name translates to "magnetic crane" in English. It was developed in the late 19th century to improve efficiency in lifting and moving heavy loads, especially in tight spaces.

A magnetkrans consists of a basic crane structure with a suspended magnet attached to the end of a boom. The magnet is usually a large electromagnet, which can be activated and deactivated as needed. The crane is typically operated remotely, allowing for better control and precision.

The magnetkrans is most commonly used in the aluminum and iron ore industries, where heavy loads need to be moved repeatedly. In these contexts, the crane's magnetic grasp reduces the risk of damage or drops, making it a more reliable and efficient option. It is also used in shipbuilding, construction projects, and other heavy lifting applications.

The design and functionality of the magnetkrans have remained relatively unchanged for more than a century. However, modern versions of the crane often incorporate advanced features such as automated controls, safety valves, and built-in load monitoring systems. Despite some reservations about its safety, the magnetkrans remains a vital tool in many industries, offering a cost-effective and reliable solution for moving heavy loads.

Its use has died down slightly over the years to be replaced by more modern and standard machinery.
