Electromagnetic Crane Hook System

Replace manual rigging, clamps, and grabs with intelligent magnetic force. Our Electromagnetic Crane Hook System delivers contactless, instantaneous lifting of ferrous materials—slashing cycle times by up to 50% while enhancing safety and reducing operational costs.

Core Components & Functionality

• 1. High-Power Electromagnet Assembly: The core lifting unit, featuring robust, insulated copper windings and a specialized ferromagnetic core. Generates a powerful, adjustable magnetic field when energized.

• 2. Integrated Hook & Mounting Assembly: Seamlessly integrates the electromagnet with the crane’s hoist mechanism. Engineered for optimal load balance and structural integrity under heavy loads.

• 3. Intelligent Power Control Unit (PCU): Supplies precisely controlled DC power to the electromagnet. Features advanced regulation for consistent holding force and incorporates crucial safety systems.

• 4. Flexible Cable Reel System (Optional): Manages power and control cables between the crane and the moving hook/magnet, preventing tangling and damage.

• 5. Operator Control System: Includes pendant controls or integrated crane cabin interfaces for easy activation/deactivation and monitoring.

Key Features & Advantages

• Unmatched Speed & Efficiency: Instantaneous material pickup and release eliminates time wasted on rigging, slinging, or clamping. Cycle times reduced by up to 50%.

• Superior Safety:

  • Eliminates manual rigging under suspended loads.

  • Secure hold on irregularly shaped or bundled scrap/steel.

  • Integrated safety features: Backup power systems (batteries/capacitors), voltage/current monitoring, automatic load weighing, and emergency release protocols.

• Reduced Labor Costs & Fatigue: Minimal operator intervention required. No need for rigging crews near the load.

• Gentle Material Handling: Minimizes damage to valuable materials (slabs, plates, finished steel) compared to mechanical grabs.

• Versatility: Handles diverse ferrous loads – scrap metal, steel plates, billets, coils, castings, machinery – even through non-magnetic barriers (e.g., thin containers).

• Enhanced Productivity: Moves significantly larger volumes per hour compared to manual or mechanical methods.

• Durability & Reliability: Built with heavy-duty materials and components designed for harsh industrial environments (dust, moisture, impacts). Low-maintenance design.

• Energy Efficient: Modern PCUs often feature regenerative braking systems, feeding energy back into the system during release.

• Scalable Power: Systems available in a wide range of lifting capacities, from a few tons to several hundred tons.

Electromagnetic Crane Hook System Typical Applications

• Scrap Metal Yards: (Primary application) Loading/unloading railcars, trucks, barges; sorting and stacking scrap.

• Steel Mills & Foundries: Handling raw materials (scrap, pig iron), moving billets, slabs, coils, and finished products.

• Fabrication Shops: Lifting and positioning steel plates, beams, and large assemblies.

• Shipbuilding & Heavy Machinery: Moving large steel sections and components.

• Recycling Facilities: Handling ferrous fractions.

• Construction Sites: Positioning large structural steel elements (with appropriate planning).

Safety Systems (Integrated)

• Automatic Load Detection & Weighing: Prevents overloads.

• Backup Power Supply: Maintains magnetic hold during primary power loss (critical safety feature).

• Voltage & Current Monitoring: Ensures optimal magnet performance and detects faults.

• Emergency Release: Controlled procedures to safely drop the load in critical situations.

• Temperature Monitoring: Protects the magnet windings from overheating.
