QS Three-Purpose Hook / Grab / Electromagnetic Overhead Crane
For factories that genuinely need one bridge crane to alternate among hook lifting, grab bulk handling and electromagnetic steel handling.
Henan Mine Crane qs three-purpose overhead crane showing the primary crane structure and lifting arrangement.
Although the source page title is 'hook overhead crane', its description identifies the QS product as a three-purpose crane that changes lifting attachments to perform hook, grab and electromagnetic operations. That distinction is important for procurement because the crane must support three different load cases and safe attachment changeover.
A three-purpose crane is valuable when these duties share one bay but are not simultaneous enough to justify separate dedicated cranes. Buyers should compare attachment-change time, maintenance complexity and required throughput before choosing a multi-purpose platform.

Product Overview
Source describes three working modes: hook, grab and electromagnetic lifter.
Source reports forged/rolled composite wheel process with about 20% longer life than traditional forged-wheel process.
Electrical connections use international-standard heavy-duty aviation plugs.
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 QS Three-Purpose Overhead Crane?
Three Handling Modes
One crane covers conventional loads, bulk material and magnetic steel.
Quick Electrical Changeover
Heavy-duty plug connections simplify grab/magnet electrical conversion.
PLC / HMI Operation
Integrated controls support clear mode management.
Reduced Crane Count
Can consolidate several intermittent handling duties into one bridge.
Mode-Specific Optimization
Each attachment can be selected around its own load and material.

Application Scenarios
| General Hook Lifting |
Machines, tooling and packaged loads. |
| Bulk Material Handling |
Grab attachment. |
| Magnetic Steel Handling |
Electromagnetic attachment. |
| Mixed-Use Workshops |
Bays that frequently change material type. |
How to Select the Right QS Three-Purpose Overhead Crane
1. Define All Three Load Cases
Maximum hook, grab and magnet suspended loads can differ.
2. Define Changeover Frequency
High-frequency switching affects connector and workflow design.
3. Define Bulk Material
Density / throughput determine grab.
4. Define Magnetic Load
Material / temperature determine magnet.
5. Define Mode Interlocks
Ensure only the selected attachment and control mode are enabled.
Three-Purpose Crane Decision
| Best Fit |
Three material types share one bay and duty is intermittent enough for attachment changes. |
| Hook Mode |
General equipment / component lifting. |
| Grab Mode |
Bulk material; size from density / throughput. |
| Magnet Mode |
Magnetic steel; define power-loss safety. |
| Connector |
Source lists IP55 heavy-duty aviation-plug connection. |
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.
