QP Type Grab and Electromagnetic Dual-Purpose Overhead Crane

Dual-Purpose overhead crane with grab bucket and electromagnetic lifting for efficient bulk material and steel handling in heavy industries.

Introduction

The QP type dual-purpose overhead crane is a smart choice for heavy-duty industrial lifting. Unlike a standard overhead crane, it combines two lifting tools in one system: a grab bucket and an electromagnetic lifter. This makes it more versatile for handling different types of materials.

What Is a QP Type Dual-Purpose Overhead Crane?

This crane is designed to perform two jobs:

• Use the grab bucket to lift loose materials like coal, sand, or scrap metal.
• Switch to the electromagnetic chuck to lift steel plates, billets, or rebar.

That’s why it’s called a dual-purpose overhead crane—it does both grabbing and magnetic lifting with one machine.

Why Choose a Dual-Purpose Overhead Crane?

Many industries need to handle both bulk and solid steel materials. Instead of installing two overhead cranes, one dual-purpose crane covers both jobs.

It brings several benefits:

• Cost-effective – no need to buy and maintain two cranes.
• Space-saving – needs only one set of tracks and structure.
• Time-saving – easy to switch between grab and magnet modes.

It’s also built for high-duty use (usually A6), which means it works well under continuous and heavy operation.

Common Applications

The QP dual-purpose overhead crane is widely used in:

• Steel mills – for loading and unloading steel scrap, billets, and slabs.
• Scrap yards – to sort and move large amounts of metal waste.
• Ports and terminals – where both loose goods and metal items are handled.
• Foundries and warehouses – for feeding materials into production lines or organizing stock.

In short, if your facility handles both loose and solid materials, this type of overhead crane gives you the flexibility you need. It’s tough, efficient, and built to handle demanding work environments.

Key Features of QP Type Dual-Purpose Overhead Crane

The QP overhead crane is specially designed for dual lifting needs—ideal for facilities handling both bulk and magnetic materials. Below are its main features:

Dual Lifting Modes (Grab + Magnet)

This is the most important feature.
The QP crane can lift:

• Loose materials (scrap, ore, coal, etc.) using a grab bucket.
• Magnetic items (steel plates, bars, billets, etc.) using an electromagnetic chuck.

Switching between grab and magnet is fast and simple. It saves space and reduces equipment costs, making it perfect for multi-use applications.

Standard and Custom Lifting Capacities

Available models include:

• 5/5t, 10/10t, and 16/16t — each figure means equal capacity for both grab and magnet.
• Customized capacities available to meet site-specific requirements or heavy load handling.

High Working Class (A6 Duty)

This dual-purpose overhead crane is rated A6, which means:

• Designed for frequent use and heavy-duty operations.
• Suitable for long working hours and higher production demands.
• Commonly used in steel mills, foundries, and recycling plants where crane use is intense.

Integrated, Complete System

Every QP crane includes:

• Bridge frame – spans the workshop; built for strength and stability.
• Trolley with hoisting mechanism – runs along the bridge, carries the grab or magnet.
• Grab bucket + Electromagnetic lifter – quickly changeable depending on material.
• Electrical & control systems – includes motors, wiring, protection, and either cab or remote control options.

All systems are integrated for safe, smooth, and reliable operation.If your job requires handling both scrap and steel, the QP dual-purpose overhead crane brings solid performance, saves space, and cuts down your equipment list.

Applications of QP Type Dual-Purpose Overhead Crane

The QP type dual-purpose overhead crane is specifically designed for handling a wide range of materials using either a grab bucket or an electromagnetic lifting system. It suits operations where both magnetic and non-magnetic materials need to be moved frequently and efficiently.

Materials Handled

This crane handles a variety of material types, including:

• Steel scrap – irregular, heavy, and often sharp-edged materials.
• Bulk metal materials – such as pig iron, broken castings, or foundry returns.
• Granular materials – like ore, metal chips, coal, or similar particles that require a grab bucket.
• Unpacking-free steel products – such as bundled steel bars, billets, steel plates, and coils, which can be lifted directly by the magnet without unpacking.

This flexibility makes the QP crane valuable in material handling processes that require both lifting precision and high efficiency.

Indoor and Outdoor Use

The QP dual-purpose overhead crane is suitable for both indoor workshops and outdoor yards. Its structure and components can be adjusted to suit different environments. Optional protective measures include:

• Rain and weather protection for outdoor models
• Dust-resistant design for dirty or open environments
• Heat-resistant parts for high-temperature areas like near furnaces

This allows for consistent performance regardless of the installation location.

Common Industrial Applications

• Steel Plants: Used to transport steel billets, coils, slabs, scrap, and metal returns. Helps automate internal transfer between different production lines or storage areas.
• Foundries: Efficient for loading furnaces with scrap metal or removing casting returns. Its dual function reduces the need for multiple cranes in the melting and casting areas.
• Scrap Yards: Handles various sizes and types of metal scrap. The magnet quickly picks up ferrous material, while the grab can scoop up non-magnetic or mixed scrap.
• Cargo Terminals and Warehouses: Used to load or unload metal cargo from trucks, railcars, or ships. Can move unpackaged or bundled metal goods with minimal manual handling.

In summary, if you’re handling a mix of scrap, bulk materials, and steel products in one place, the QP type dual-purpose overhead crane is an efficient, space-saving, and cost-effective solution. It's built to take on heavy-duty tasks in both demanding indoor and outdoor environments.

Selection Tips for Buyers

Choosing the right QP type dual-purpose overhead crane can make a big difference in efficiency and safety. Here are some key tips to help you decide:

How to Choose Between Different Capacities

• Match the lifting capacity to your heaviest load to avoid overloading.
• For mixed loads, consider a crane with dual capacities (e.g., 5/5t or 10/10t) to handle both grab and magnet operations efficiently.
• If unsure, opt for a slightly higher capacity for future-proofing.

Choosing the Right Grab Type and Magnet

• Grab bucket types vary by material density and volume: light, medium, heavy, or super-heavy. Select one based on what you mostly handle.
• For steel plates or billets, check the magnet suction capacity and diameter to ensure a secure grip.
• Custom grab sizes and magnet types are available—discuss your exact materials with the supplier.

Installation Site Preparation Checklist

• Confirm the span and height clearances match the crane specs.
• Check the power supply compatibility (usually three-phase 380V, 50Hz).
• Ensure the site is free of explosive or corrosive hazards.
• Plan for crane runway beams and structural support capable of handling the crane’s weight and maximum wheel loads.
• Decide on operation mode (ground remote control or cabin) and ensure space and safety for operators.

Considerations for Indoor vs. Outdoor Use

• For indoor use, ensure the crane fits within building dimensions and ventilation requirements.
• For outdoor use, confirm the crane has weather protection features and is rated for the local climate (temperature, humidity, dust).
• Outdoor cranes might need additional corrosion protection and waterproofing on electrical components.
