Product catalog summary
Overview: The document provides a detailed overview of Eriez lifting magnets, emphasizing their efficiency, safety, and versatility in handling steel and iron materials without the need for traditional lifting equipment like slings, hooks, or cables. The use of magnets is highlighted for reducing manpower, increasing safety, and improving operational economy.
Types of Lifting Magnets:
  • Permanent Lift Magnets: These can lift up to 10,000 lbs (4,535 kgs) and are suitable for both flat and round materials, operating without a power supply.
  • Electric Lift Magnets: Capable of handling up to 59,000 lbs (26,761 kgs), these magnets come in various models to accommodate different shapes and sizes.
  • Lift Systems: Complete systems include lift beams with multiple magnets and controls for efficient material handling.
Product Features and Benefits:
  • Bi-Polar Magnets: Ideal for handling pipes, rounds, bundles, and shapes with optional pole-plate configurations.
  • Heavy-Duty Rectangular Magnets: Designed for maximum efficiency in handling multiple plates.
  • SafeHold® Permanent Magnets: Provide practical lifting solutions with minimal contact and no need for manual activation or electricity.
SafeHold® Series:
  • APL Series: Designed for flat materials, these magnets automatically turn on and off, requiring no electricity and maintaining continuous power until turned off.
  • EPL Series: Suitable for flat materials, these magnets operate manually and are ideal for machine-shop operations.
  • XPL Series: Handles both flat and round materials, ideal for machine shop operations, and operates without a power supply.
  • RPL Series: Features a two-pole design for handling round and flat materials, offering continuous power without the need for a power supply.
Specifications: The document provides detailed specifications for various models, including lifting capacities, breakaway forces, and dimensions. It notes that actual ratings are based on flat, clean, polished steel plates and that factors such as surface condition and material shape can affect holding power.
Additional Features: Highlights include ease of installation and use, elimination of hooks and slings, and availability of continuous-duty electro lifting magnets with built-in rectifiers and drop-control circuits.
Specifications Overview: Detailed specifications for various models of lifting magnets are provided, including dimensions, lifting capacities, and electrical requirements. These magnets are designed for heavy-duty applications such as lifting beams, channels, bars, and flat steel plates.
Magnet Models and Capacities: The document lists multiple models with varying maximum lifting capacities, breakaway forces, and dimensions. For example, Model 449 has a maximum lifting capacity of 930 lbs (422 kg) with a breakaway force of 1,860 lbs (845 kg).
Design and Construction: Magnets are designed with a three-pole system for a reliable grip on flat surfaces, featuring a computer-designed aluminum coil, weatherproof welded construction, and Class H insulation. They are suitable for 100-percent duty cycles and available in high-temperature models.
Applications: These magnets are used in multiple-plate handling applications, such as loading and unloading ships, barges, rail cars, and trucks. They are also effective in handling billets, slabs, and large fabrications.
Bi-Polar Magnets: Square and rectangular bi-polar magnets are designed for lifting banded coils and bundled shapes, usable in single or multiple-magnet applications with optional pole configurations for different shapes and temperatures.
Rectifiers: Eriez provides fixed-voltage silicon rectifiers for use with electromagnets, offering fixed voltage DC power for single-phase and three-phase operations, designed for full-capacity operation in ambient temperatures up to 110°F (43°C) and elevations up to 2,000 feet (610 meters).
Conclusion: The document provides comprehensive technical details on the specifications, applications, and configurations of Eriez lifting magnets and rectifiers, highlighting their suitability for heavy-duty industrial applications.

lifting magnets-1

lifting magnets complete line Magnets possess a unique property of attraction which can be harnessed to ease and speed one’s work. The payoff is an immediate improvement in efficiency and operating economy. Magnets lift and transfer steel and iron of any weight and shape without slings, hooks or cables--and without marring the surface. And without marring the surface. They require fewer operators and helpers, and when properly installed and operated, provide greater safety than many other mechanical materials handling devices. Lift, move or position regardless of size, weight or shape— in fewer man hours — reliably and economically. Lifting magnets make quick work of difficult, time-consuming steel handling.
