Significant growth of electric cargo handling cranes has substantially increased efficiency and minimized environmental impact on terminals and operational processes . However, the complexity and associated costs with integrating these systems have been a significant concern for many operators. A key innovation that can help mitigate some of these concerns is the magnetic braking system for electric cargo handling cranes .

Existing braking methods used in port logistics systems include dynamic braking and electromagnetic braking. Eddy current braking is accomplished by electromagnets embedded in the axles that turn against a copper track. This process generates a electromagnetic force and induced currents in the metal loop that act as a retarding force to slow down the crane. In contrast, dynamic braking relies on the motor to operate in opposite and generate heat as a braking mechanism . However, these methods have several drawbacks such as high maintenance costs and frequent heat generation that can impact system reliability and safety .

This magnetic braking system offers an innovative solution for advanced port logistics systems. The technology relies on the use of advanced electromagnetic materials to create a robust magnetic field that reacts with the magnetic field-induced current generated in a separate copper loop. Upon attaining a set speed , a non-penetrating magnetic field is engaged that creates electrodynamic braking . This innovative technology eliminates the need to generate excessive heat , reduces wear and tear, and substantially extends the lifespan of the e-drive motor .

Another essential advantage of magnetic braking is its potential to increase safety in port logistics systems. Existing methods have been criticized for their reliance on eddy currents , which can sometimes be unstable . During an emergency, magnetic braking reduces the strain on the braking system, giving operators critical time to safely stop the crane. In addition, this technology supports a reduced deceleration profile, resulting in reduced payload displacement and protecting the crane's operational safety from potential impacts.

The implementation of magnetic braking in electric cargo handling cranes appears to be a mutually beneficial situation for both the operator and the cargo handling facility . Its advantages to enhance the crane's braking performance , expand its lifespan, and ensure staff safety, электромагнитный тормоз принцип работы magnetic braking is becoming the preferred solution for a significant proportion of industry players seeking enhanced efficiency and reduced operational costs.
