MN Grab & Hook Dual-Purpose Gantry Crane

For mixed-material yards that need one gantry crane to alternate between bulk materials such as coal or ore and conventional hook loads.

The MN grab-and-hook dual-purpose gantry crane uses a dedicated quick-change arrangement so the crane can switch between grab handling for bulk materials and hook lifting for general cargo.

For procurement, treat grab and hook operation as two different duty cases. Bulk density, particle size, grab self-weight and required throughput determine the grab duty, while the hook duty is determined by the heaviest general load and rigging.

Product Overview

Quick-change arrangement supports grab and hook switching.

Grab mode is described for coal, ore and similar bulk material; hook mode is for general cargo.

Grab uses closing and supporting ropes for material pickup.

Any capacity, span, speed, synchronization accuracy, wind limit, temperature limit, throughput or other contractual value that is not explicitly published by the source should be engineered from the actual project and written into the technical agreement.

Why Choose MN Grab & Hook Gantry Crane?

Two Load Types, One Runway

Useful where bulk and general cargo share the same handling area.

Quick Changeover

Source specifically describes a quick-change device between grab and hook.

Fast Grab Response

3–5 second source-reported opening/closing supports repetitive handling.

VFD Control

Supports smoother, faster operating cycles.

Modular Maintenance

Core parts can be replaced quickly according to the source.

Application Scenarios

How to Select the Right MN Grab & Hook Gantry Crane

1. Define Hook Load

Provide the heaviest general load including rigging.

2. Define Bulk Material

Provide density, particle size, moisture and abrasiveness.

3. Define Required Throughput

Tonnes per hour determines grab volume and cycle targets.

4. Define Changeover Frequency

Frequent attachment changes can affect overall productivity.

5. Define Interlocks

Specify the safe connection / disconnection and operating-mode logic.

Safety & Control: What Buyers Should Confirm

Installation & Maintenance

Before manufacture, confirm rail center distance, runway length, rail elevation, foundation or building-runway capacity, available lifting height, process clearances, power supply and erection access. Outdoor projects should include wind, rain, temperature, corrosion and anchoring conditions.

Maintenance should follow the final supplied crane manual and actual duty. In addition to hoisting, brakes, ropes, wheels, drives, rails, limits and electrical systems, inspect product-specific devices such as grabs, magnets, gantry hooks, gate equipment, tipping mechanisms, encoders, cameras or automation hardware.

Frequently Asked Questions

How is final crane capacity selected?

Use the complete suspended load, including the load plus grab, magnet, gantry hook, lifting beam, rigging or any other below-the-hook equipment.

Can span and lifting height be customized?

Yes. Unless the source publishes a range, these are project-specific and should be selected from the rail layout and working envelope.

What site drawing should I send?

Send a plan and cross-section showing rails, foundations or building runway, loading positions, obstacles, travel length and available clearances.

Can control or automation be customized?

Where the source supports VFD, PLC, linked operation, cameras, access control or other functions, the final scope should be defined from the buyer's process and acceptance requirements.

How should source-reported performance numbers be used?

Treat them as source product data. If a value is contract-critical for a new project, define the test conditions and acceptance method in the technical agreement.
