QL Electromagnetic Lifting Beam Overhead Crane
For steel-handling buyers who need a fixed electromagnetic beam to pick long magnetic products efficiently without a rotating attachment.
Henan Mine Crane ql electromagnetic beam crane showing the primary crane structure and lifting arrangement.
The QL electromagnetic lifting-beam crane combines a bridge-crane platform with an electromagnetic lifting beam for steel plates, ingots, sections and other magnetic material. It is most appropriate when a long load needs multiple magnetic pickup points but does not require the rotating mechanism of QLC / YC-type cranes.
The buyer should define load length, thickness, temperature, surface condition, magnet spacing and stacking pattern. The lifting beam and magnets are part of the suspended load and must be included in capacity calculations.

Product Overview
Designed for magnetic metal such as steel plate, ingot and sections.
Core parts such as wheels, couplings and drum groups use modular standardized interfaces for easier replacement.
Source reports magnet attraction above 1.5 times rated lifting capacity.
Where the source page does not publish a numerical capacity, span, speed, duty, positioning accuracy or other guaranteed performance value, the final value should be selected and agreed from the actual project rather than copied from a similar crane.
Why Choose QL Electromagnetic Beam Crane?
Long Magnetic Load Pickup
Multiple magnets on a beam distribute pickup points along plates / sections.
Modular Components
Standardized interfaces simplify replacement of major mechanisms.
Emergency Holding
Source-confirmed battery retention provides contingency after power loss.
Anti-Sway
Helps positioning over steel stacks.
Simpler than a Rotating Beam
Suitable when orientation change is not required.

How to Select the Right QL Electromagnetic Beam Crane
1. Define Magnetic Load Geometry
Provide min/max length, width and thickness.
2. Define Temperature / Surface
Hot scale, gaps and surface condition affect magnet performance.
3. Define Magnet Spacing
Match pickup points to load stiffness and dimensions.
4. Define Backup Hold
Specify acceptance for emergency battery retention.
5. Define Anti-Sway Need
Translate stack clearance into measurable positioning requirements.
Magnet Safety Data
| Magnet Attraction |
Source states at least 1.5 × rated lifting capacity. |
| Backup Hold |
Source states 15–30 min after main power loss. |
| Anti-Sway |
Source states swing within 5° on the referenced system. |
| New Project |
Treat these as source product data; write final guaranteed values into the technical agreement. |
Safety & Control: What Buyers Should Confirm
• Rated capacity, overload protection and load-indication requirements
• Hoisting / travel limits, braking and emergency-stop requirements
• Attachment-specific safety such as magnet backup, grab interlocks, clamps or tandem synchronization where applicable
• Operator control method, visibility and safe access
• Anti-collision, anti-sway, positioning or automation requirements where required by the process
• Factory / site acceptance, load tests and project-specific functional tests
Installation & Maintenance
Before manufacture and installation, confirm runway span, rail / runway-beam condition, elevation, straightness, available headroom, power supply and erection access. Special attachments, multi-trolley systems, cantilevers, suspended runways and automated layouts should be coordinated with the workshop or yard drawing before production.
Maintenance should follow the supplied crane manual and actual duty. Inspection normally covers the hoisting mechanism, brakes, ropes, hooks / attachments, wheels, drives, fasteners, limits and electrical systems, with additional checks for magnets, grabs, clamps, sensors, encoders or automation hardware where fitted.

Frequently Asked Questions
How is the final crane capacity selected?
Use the total suspended load, including the load itself plus any beam, grab, magnet, clamp, spreader or rigging that remains below the hook.
Can the capacity, span and lifting height be customized?
Yes, these values are project-specific unless a source range is explicitly listed on this page. Provide the workshop / yard data for engineering selection.
What should I provide for a faster quotation?
Provide load drawings or dimensions, maximum suspended load, span, lifting height, runway length, operating cycle, environment and the specific process function that makes this product necessary.
Can control and automation be customized?
Where the source supports PLC, VFD, positioning, WMS/MES/DCS or remote functions, the final scope should be defined from the buyer's interface and acceptance requirements.
How should source-reported performance numbers be treated?
They describe the source product configuration. Any value that matters contractually for a new project should be written into the technical agreement and acceptance plan.
