Features and Installation of Excavator Electromagnet

As construction machinery evolves, excavators are now vital on sites. However, handling heavy objects like scrap steel often demands specialized lifting equipment. To overcome this, excavators are being retrofitted with electromagnets, enhancing their effectiveness in diverse work environments. Below, we'll outline the features and installation process of electromagnet on excavators.
Major Features of Excavator Electromagnet
Excavator electromagnets offer a range of significant features and benefits that enhance their utility and efficiency on construction sites and in various industrial applications. These features include:
  • Strong and Efficient Operation: Electromagnets create a potent base magnetic field for quick attachment and release, ensuring fast and efficient handling of heavy objects, from large scrap steel to small metal pieces.
  • Versatility: Equipped with fork arms, electromagnets enable diverse applications, handling not only metal materials like scrap steel but also loading/unloading long objects and non-metallic waste such as wood and plastic.
  • Exceptional Design and Materials: Careful magnetic circuit design and high-quality materials, including aluminum wire for the coil and high manganese steel for the protective plate, ensure stability, durability, and resilience in harsh environments.
  • Lightweight and Energy-Efficient: Despite its lightweight structure and low energy consumption, the electromagnet exhibits substantial lifting capacity and extended service life, enhancing operational efficiency while reducing energy costs.
  • Rational Insulation Design: Thoughtful insulation structures, including vacuum drying and vacuum impregnation techniques, bolster the coil's electrical and mechanical performance, ensuring safe and reliable operation even in damp or dusty conditions.
  • Flexible Control: Adaptable control methods, typically fixed voltage but switchable to field excitation control, facilitate enhanced lifting capacity. Easy operation and adjustable control parameters meet diverse operational needs.
  • Simple and Reliable Structure: The electromagnet boasts a straightforward, secure, and reliable structure, suitable for various lifting equipment. Whether on construction sites, port terminals, or scrap yards, it operates steadily and reliably, ensuring smooth project progress.
Installation Steps
Below, you'll find a thorough and carefully explained set of instructions outlining each step required to install electromagnets onto excavators.
  1. Weld Platform: Weld a platform onto the excavator's rotating base at the rear to accommodate the electromagnet and related gear.
  2. Mount Generator Set and Control Cabinet: Securely attach the generator set and electromagnet rectifier control cabinet onto the platform for stability.
  3. Install Control Switch: Place the absorption/release material switch from the control cabinet inside the operator's cab for convenient operation.
  4. Fix Cable Connectors: Attach cable connectors onto the top of the excavator arm near its end, securing them with screws for a stable power link.
  5. Remove Bucket: Take off the bucket to prepare for electromagnet installation.
  6. Attach Electromagnet: Install the lifting electromagnet at the excavator bucket's position, securing it with locking pins and lubricating oil for smooth functioning.
  7. Connect Power and Control Lines: Link the three-phase power lines from the generator set to the electromagnet rectifier control cabinet's power terminals. Then, lead control lines from the cabinet to the operator's cab for the switch.
  8. Connect Cables: Guide heavy cables from the control cabinet to the cable connector on the excavator arm's head, ensuring secure connections to the lifting electromagnet.
  9. Verify Connections: After connecting all cables and lines, confirm their correctness to ensure operational safety and reliability.
  10. Perform Checks: Fill the generator set's fuel tank and confirm normal power output. Once no abnormalities are detected, switch on the power air switch inside the control cabinet to conduct absorption/release tests and assess the electromagnet's operational status.
Following these installation steps completes the integration of the electromagnet onto the excavator. This innovative addition enhances the excavator's versatility, allowing it to fulfill crucial roles across construction sites, port terminals, and scrap yards. With electromagnets, excavators not only boost efficiency but also lower labor costs and energy usage, offering a streamlined solution for engineering projects.
