QDX Type Double Beam Electric Overhead Crane with Trolley

Product Overview

QDX type Double Beam Electric Overhead Crane with Trolley is a new type of bridge crane developed based on QD traditional double-beam crane.

It adopts systematic, standardized and modular design theory to create a new type of bridge crane with light weight, general purpose, energy saving, maintenance-free and high-tech content.

QDX type Double Beam Electric Overhead Crane with Trolley is designed to meet medium and heavy industrial lifting requirements, covering almost all manufacturing processes.

QDX type Double Beam Electric Overhead Crane with Trolley was manily used in Manufacturing workshop, metallurgy, petroleum, petrochemicals,ports,railway,civil aviation,power station,food industry, paper making,building material, warehouses and other material handling application.

Depending on your actual use, there are different overhead cranes for customers to choose from.

We have an experienced team of crane engineers.

We design the right bridge crane system for you, and provide a full range of after-sales services to enable your crane to operate quickly, stably and reliably.

Key Advantages

This crane model is engineered for long service life and low maintenance in demanding industrial environments. Buyers choose it because it is built by the factory itself, with steel structure processed by CNC cutting and automated welding for dimensional accuracy and consistent quality.

• Compact structure, modular design, optimize your investment QDX type Double Beam Electric Overhead Crane with Trolley has a compact structure, light deadweight, low wheel pressure, uniform load distribution, which can greatly reduce the project cost and heating cost, and is more convenient to maintain. Compared with traditional bridge cranes, the size of European bridge cranes is reduced by 10%-15% with the change of load and weight. The heavier the load, the smaller the size allowed by the European crane, the more investment savings, and the higher the return on investment.
• Green concept leads innovation, saves space and energy Lighter weight, lower wheel pressure, and lower energy consumption. The durability of the crane components and the crane makes you do not need frequent maintenance. The compact crane structure maximizes the availability of the working space.
• High safety, high reliability, easy maintenance QDX type Double Beam Electric Overhead Crane with Trolley use advanced technology and processing equipment, and carry out strict quality control and inspection to ensure product quality and high safety.
• The maintenance-free and maintainable design concept makes the material handling equipment easy to maintain and operate while competing with other equipment.
• Customized configurations, wide range of options QDX type Double Beam Electric Overhead Crane with Trolley can be customized with weights ranging from 5 tons to 320 tons. Customized tilt hoists, anti-sway devices, automatic positioning devices, winch maintenance and monitoring devices or remote diagnostic tools are available.

• Optional intelligent functions: speed extension (micro speed, high speed), anti-collision, electronic swing release, regional restriction setting, multi-purchase coordination and unmanned full-automatic, etc.
• Depending on the lifting cargo, the crane can be equipped with various special lifting equipment, such as: lifting beam, electromagnet, grab, C-hook, lifting clamp (drum clamp), container spreader, etc.

Applications & Working Conditions

The QDX Type Double Beam Electric Overhead Crane with Trolley is used across industrial plants, warehouses, steel mills, power stations, ports and logistics centers. It is available with optional lifting attachments such as lifting beams, electromagnets, grabs, C-hooks and coil tongs for special material handling.

Standard models operate in ambient temperatures from -20°C to +50°C. For special environments, we can supply explosion-proof electrics, high-temperature paint systems, dust-proof protection or corrosion-resistant coatings. Tell us your working condition and our engineers will confirm the correct configuration.

Customization Options

We customize span, lifting height, working class, control mode (pendant, wireless remote or cabin), and add frequency conversion speed control, explosion-proof protection or special coatings to suit your environment. Tell us your requirements and our engineers will prepare a tailored proposal.

Standard Supply Scope

Your order includes the complete crane structure, travelling mechanism, hoisting trolley or hoist, electrical control system, safety devices (limit switches, overload limiter, buffers, emergency stop), operation manual and inspection certificates. Optional extras include wireless remote control, frequency inverter, cabin with heater/air conditioner, lighting and special lifting attachments.

Quality Control & Testing

All structural welding is performed by certified welders and inspected before painting. Each crane undergoes no-load and full-load testing on our test bench, including brake test, limit switch verification and electrical safety check. Third-party inspection (SGS or buyer-nominated) is available before shipment.

Packing & Shipping

Cranes are shipped in knockdown form with steel structure, wheels, trolley, electrics and hardware carefully packed to prevent damage during ocean freight. Export packing follows our standard seaworthy specification, with wooden cases for electrics and control panels. Delivery options include FOB, CIF and DDP to your port.

Installation & After-Sales

We offer installation supervision and commissioning by our engineers, or fully turnkey installation by our experienced team. After commissioning we provide operator and maintenance training, a complete documentation package, and 24/7 spare parts and technical support for the lifetime of the crane.

What to Include in Your Inquiry

To receive an accurate quotation, please send us the following details with your inquiry: required lifting capacity (ton), span or working radius, lifting height, duty / working class, control method (pendant, radio remote or cabin), power supply voltage, site environment (indoor, outdoor, high temperature, dusty, explosion-proof area), and quantity. The more detail you provide, the faster our engineers can confirm the design and price.
