From Hooks to Magnets- Top 5 Designs for Heavy Lifting
Selecting the Best Open Winch Double Girder Overhead Crane in China

Choosing the right open winch double girder overhead crane is more than just picking a tonnage or span. In real-world industrial settings, the crane you select can affect safety, workflow efficiency, and even long-term operating costs. A crane that's perfectly suited to your material type, lifting height, or factory layout can make operations smoother, reduce downtime, and protect your workforce.

In China, open winch double girder cranes are widely used across industries because of their practical design and versatility. They're especially popular in factories, steel plants, ports, and logistics centers, where reliable lifting equipment is essential.

This guide is aimed at helping buyers understand the differences and relationships between the five main series of open winch cranes: QD, QE, QB, QC, and QL. By the end, you'll know which type fits your operational needs best, what makes each unique, and why the open winch design is so widely preferred in industrial environments.

While all five crane series share the open winch design in China , they serve distinct functions:

QD Series: Double Girder Open winch Crane for Heavy-duty general-purpose lifting 3 ton to 550 ton

QE Series: Dual-trolley open winch crane for handling for long or heavy materials 5+5 – 200+200 tons

QB Series: Explosion-proof open winch crane for operation for hazardous environments 5 ton to 50 ton

QC Series:Open winch overhead crane with magnetic chuck for electromagnetic lifting for steel billets and scrap 5 ton to 32 ton

QL Series: Open winch bridge crane with Revolving electromagnet spreader for precise steel handling 10+10 – 200+200 tons

Compared with European style NLH overhead crane with electric hoist trolley for load handling with 3 ton to 80 ton

Key Advantages of Open Winch Design Across All Series:

• Easier inspection and maintenance due to exposed components
• Flexible attachment options: hooks, grabs, or electromagnetic lifters
• Adaptable to a wide range of spans, capacities, and lifting heights
• Reduced downtime and lower maintenance costs

This section sets the stage for a practical understanding of the cranes themselves. Later, we'll explore each series in depth, highlighting how they differ, where they excel, and why buyers often turn to China for cost-effective, high-quality solutions.

• Proven Manufacturing Standards: Many Chinese manufacturers follow CE, ISO, and industry-specific standards, ensuring safety, durability, and long-term reliability.
• After-Sales Support: Suppliers often provide detailed installation guidance, ready supply of spare parts, and maintenance consultation, helping reduce downtime and keep operations running smoothly. Check more types of overhead cranes for sale in  China.  

Beyond cost and support, the open winch design itself adds practical value.

• Easy Inspection and Maintenance: Components are exposed, allowing quick checks on ropes, brakes, and gears without disassembling the crane.
• Supports Hooks, Grabs, and Electromagnetic Attachments: Flexibility to handle different materials efficiently, from steel coils to long pipes or scrap metal.
• Adaptable to Multiple Industrial Scenarios: Suitable for steel mills, ports, warehouses, logistics centers, and construction sites, the open winch design allows smooth operation across various applications.

Choosing an open winch double girder crane from China combines affordability, flexibility, and practical design features. It ensures your lifting operations are safe, efficient, and aligned with the specific requirements of your industry.

How the Series Relate and Complement Each Other

When selecting a double girder open winch crane, tonnage and span are just the starting point. The real decision should be function-driven. Each series in the top 5 lineup serves a specific purpose, and understanding their relationships helps buyers make smarter choices.

Function-Based Decision:

• QD Series: Acts as the backbone for general heavy lifting across industrial applications. Reliable for high-duty operations.
• QE Series: Adds dual-trolley precision for long or unusually shaped materials. Ideal for steel beams, pipes, molds, or wind tower sections.
• QB Series: Specialized for hazardous or explosive environments, maintaining safety without sacrificing lifting efficiency.
• QC Series: Focused on steel handling with electromagnetic lifting, reducing manual work and increasing speed.
• QL Series: Advanced derivative of QC with revolving electromagnets for tight or complex layouts, providing precision placement.

Shared Advantages Across Series:

• Open winch trolley allows easy inspection and maintenance.
• Supports a wide range of attachments: hooks, grabs, and electromagnets.
• Flexible enough to adapt to different industries and operational workflows.
• Cab or remote control options for operator safety and convenience.

Buyers' Perspective:

• Start by understanding your operational needs: material type, load size, lifting frequency, and work environment.
• Match the series to the specific function rather than just lifting capacity.
• Consider complementary series if operations involve mixed material types or specialized handling, e.g., combining QD for general lifting with QC/QL for steel handling.
• Factor in maintenance ease, control options, and long-term adaptability when choosing a crane series.

Pricing Overview

Understanding the cost of an open winch double girder crane is crucial for budgeting and operational planning. Prices vary depending on capacity, span, attachments, and customization, but having a general reference helps buyers make informed decisions.

Summary Table of Top Series:
Before diving into specifics, here's a snapshot of the main crane series, their capacities, spans, lifting heights, and Price Range for Reference Onlys. This gives a clear picture of what to expect financially for different industrial needs.

Factors Influencing Price:
Crane pricing isn't one-size-fits-all. Several technical and operational factors directly affect the cost:

• Capacity: Higher tonnage cranes require more robust girders, motors, and components, which increases cost.
• Span and Lifting Height: Longer spans and taller lifts mean more steel structure, stronger hoists, and higher material costs.
• Attachments: Adding hooks, grabs, or electromagnets increases complexity and overall price.
• Customization: Special duty classes, explosion-proof features, or anti-sway systems add to the expense.
• Control Method: Cabin, pendant, or remote/PLC-based automated controls affect both equipment and installation cost.

Practical Tips for Buyers

Choosing the right crane isn't just about price or capacity—it's about ensuring your equipment matches your operational needs. Thinking ahead saves downtime, reduces maintenance issues, and improves workflow efficiency.

Function First: Before selecting a series, carefully consider what the crane will actually handle and how often.

• Identify your material type: Are you lifting steel billets, long pipes, heavy machinery, or hazardous materials?
• Evaluate the environment: Will the crane operate indoors, outdoors, in a hazardous area, or in a confined space?
• Determine lifting frequency and precision: How often will the crane be in use, and how precise does placement need to be?

Manufacturer Considerations: Choosing a reliable manufacturer can impact long-term costs and support.

• Chinese open winch crane manufacturers: Often provide cost-effective options with high customization potential.
• Certifications: Look for CE, ISO, or industry-specific certifications to ensure quality and compliance.
• After-sales support: Check for installation guidance, spare parts availability, and maintenance services.

Series Selection Tips: Once you understand operational needs, select the series that aligns with your materials, workflow, and environment:

• QD Series: Heavy-duty, high-frequency lifting for a wide range of industries.
• QE Series: Dual-trolley design for precise handling of long and heavy loads.
• QC & QL Series: Specialized for steel handling, scrap materials, and applications requiring electromagnetic lifting or rotation.

Selecting the right double girder overhead crane goes beyond simply comparing tonnage or span. The key is understanding what you actually need the crane to do. Functionality—whether handling heavy loads, long materials, hazardous environments, or steel-specific applications—should guide your decision first.
