QP Grab & Electromagnetic Dual-Purpose Overhead Crane
For mixed-material facilities that need one double-girder crane to handle bulk material by grab and magnetic steel with an auxiliary hook-mounted electromagnet.
Henan Mine Crane qp grab & electromagnetic crane showing the primary crane structure and lifting arrangement.
The QP dual-purpose crane is a double-main-girder, single-trolley bridge crane with main and auxiliary hoisting. The main hoist uses two winch mechanisms to control the grab support and closing ropes. The auxiliary hoist uses a hook carrying an electromagnetic lifter.
Buyers should separate the two load cases in the RFQ: bulk-material grab duty and electromagnetic steel duty have different throughput, load and attachment requirements. The crane should be sized for the governing load and duty while maintaining safe mode changeover.

Product Overview
Double main girder, single trolley, main and auxiliary hoisting.
Main hoist uses two identical winch mechanisms for grab support and closing ropes.
Auxiliary hoist uses one motor, reducer and double brakes; hook carries electromagnetic lifter.
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 QP Grab & Electromagnetic Crane?
Bulk + Magnetic Steel Handling
One crane serves two very different material streams.
Dedicated Grab Winches
Support and closing ropes are separately controlled by dual winch mechanisms.
Auxiliary Magnet Hoist
Magnetic lifting remains available without replacing the main grab system.
Quick Electrical Conversion
IP55 aviation-plug connection supports reliable attachment electrical changes.
Cab + Remote Control
Source allows both operator arrangements.

How to Select the Right QP Grab & Electromagnetic Crane
1. Define Grab Material / Throughput
Bulk density and cycles determine grab duty.
2. Define Electromagnetic Load
Material type and magnet arrangement determine auxiliary load.
3. Define Simultaneous / Sequential Use
Clarify whether main and auxiliary systems ever operate together.
4. Define Attachment Connections
Confirm power and quick-connect requirements.
5. Define Control Modes
Specify cab, remote and safe mode-selection logic.
Two Load Cases, One Crane
| Grab Duty |
Define bulk material, throughput and grab load. |
| Electromagnetic Duty |
Define magnetic material, magnet arrangement and backup-power needs if required. |
| Main / Auxiliary Hoists |
State whether simultaneous use is permitted or required. |
| Mode Changeover |
Define electrical / procedural interlocks during attachment changes. |
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.
