QEN Grab & Hook Dual-Purpose Overhead Crane
For plants that need one bridge crane to handle both conventional hook loads and bulk material with a removable hydraulic grab.
Henan Mine Crane qen grab & hook crane showing the primary crane structure and lifting arrangement.
The QEN dual-purpose bridge crane is a general overhead crane with two load-handling modes: hook lifting and a removable hydraulic grab. This can reduce the need for separate cranes where the production mix alternates between equipment / packaged loads and bulk material.
The buyer should evaluate how often the crane changes attachments, the grab power / connection method, material density and whether the changeover time is acceptable for the production schedule.

Product Overview
General bridge crane with hook plus removable hydraulic grab.
VFD control is source-listed for improved crane speed and handling efficiency.
Grab is made from high-strength alloy steel.
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 QEN Grab & Hook Crane?
Two Handling Modes
Use one crane for hook loads and bulk grab work.
Removable Hydraulic Grab
Attachment can be removed when general hook lifting is needed.
VFD Motion
Smooth, controllable travel suits mixed production duties.
Maintainable Grab
Modular pins and teeth simplify wear-part replacement.
Lower Fleet Complexity
Useful when two different load types share one bay but do not justify two dedicated cranes.

Application Scenarios
| Mixed Material Warehouses |
Alternate between packaged loads and loose material. |
| Waste / Bulk Handling |
Hydraulic grab handling with hook mode available for maintenance. |
| General Manufacturing |
One crane serving production and bulk cleanup / transfer. |
| Stockyards |
Flexible load-handling attachment strategy. |
How to Select the Right QEN Grab & Hook Crane
1. Define Both Load Cases
Provide maximum hook load and maximum grab load separately.
2. Define Bulk Material
Density and particle size determine grab volume and suspended load.
3. Define Attachment Changeover
Explain how often hook and grab modes change.
4. Define Hydraulic / Electrical Interface
Confirm connection method and isolation during attachment changes.
5. Confirm Duty and Throughput
Mixed operation may require different cycle calculations for each mode.
Attachment Changeover Planning
| Hook Mode |
Define general equipment / packaged load requirements. |
| Grab Mode |
Define material density, grab size and throughput. |
| Changeover Frequency |
Frequent changes may justify a different attachment strategy or dedicated crane. |
| Maintenance |
Stock modular wear parts for the hydraulic grab based on actual material abrasiveness. |
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.
