Double Girder Gantry Cranes | Maximize Your Heavy Lifting Efficiency

A double-girder gantry crane plays a crucial role in the world of heavy industry, logistics, and large-scale construction. Efficiency and safety are not just goals—they are imperatives in the modern industrial society. Whether you’re moving heavy machinery, handling shipping containers, or assembling massive structural components, you need crane equipment you can rely on. Dejun Cranes are designed to be the workhorse of your operation, lifting immense loads with ease and transforming your material handling processes.

Why Choose a Double-Girder Gantry Crane?

Unlike a single-girder gantry crane, the double-girder gantry crane design is to provide superior strength, stability, and hook height. This makes it the ideal solution for the most challenging applications where capacity and precision are critical.

Key Features & Advantages

• Exceptional Heavy-Duty Capacity: Built to handle capacities from 5 tons to 800 tons and beyond. Perfect for lifting heavy, bulky, or oversized items that are beyond the scope of standard cranes.
• Superior Hook Height: The double-girder design allows for a greater lift height beneath the hook, maximizing your usable workspace beneath the crane.
• Enhanced Stability & Durability: The twin bridge girders distribute the load evenly, minimizing deflection and ensuring smooth, stable, and safe lifting operations, even at maximum capacity.
• Customizable for Your Needs: Dejun Cranes understands that no two worksites are identical. Our gantry cranes can be customized with various span lengths, lifting heights, runway systems, and control options (including pendant control, radio remote control, or fully enclosed operator cabins).
• Built for Outdoor Applications: With options for weather-resistant construction, these double girder gantry cranes perform flawlessly in shipyards, open-air storage yards, and construction sites, regardless of the elements.
• Advanced Safety Features: Your safety is our priority. Our cranes come equipped with overload protection, limit switches, emergency stop buttons, and secure braking systems to ensure complete operational safety.

Ideal Applications for Your Business

• Shipping Ports & Terminals: For loading and unloading containers and heavy cargo from ships and trucks.
• Heavy Equipment Manufacturing: To move large machinery parts and assemblies along the production line.
• Steel Fabrication and Warehousing: For handling steel coils, plates, and lengthy structural beams.
• Power Plants & Large-Scale Construction Projects: To install and maintain heavy generators, turbines, and pre-cast concrete sections.
• Aerospace and Automotive Sectors: For precise positioning of large components during assembly.

Case | 30 Ton Gantry Cranes for Sale to the United Arab Emirates Steel Mill Client

From the initial inquiry in November 2024 to the final deal in July 2025, Dejun Cranes customized two 30-ton (25+5) double-girder gantry cranes for their heavy-duty outdoor operation area, specifically designed for lifting large steel components. This project not only solved the client’s lifting challenges in harsh outdoor conditions but also demonstrated our professional strength in heavy lifting equipment and our deep understanding of the Middle East market.

Customer Background and Challenges

The client is from the rapidly developing United Arab Emirates. Their business involves large-scale steel structure processing, logistics warehousing or infrastructure construction. The client requires two high-performance double girder gantry cranes for outdoor storage yards, to frequently lift steel coils, steel beams or large steel components weighing up to 30 tons.

The core challenges of the client’s site:

• The harsh outdoor environment: The high temperatures, high humidity, strong sandstorms and intense ultraviolet rays in the United Arab Emirates impose extremely high requirements on the durability, anti-corrosion ability and electrical system stability of the gantry crane equipment.
• High-intensity operation demands: The lifting tasks are heavy, and the gantry crane must have a high working level, smooth operation and excellent lifting capacity.
• The balance between safety and efficiency: When lifting high-value and heavy steel components, it is necessary to ensure absolute operational safety while pursuing high efficiency to guarantee the overall logistics progress.

Project timeline and key stages:

November 2024: Initial Inquiry and Demand Deepening
The client sent out a preliminary inquiry for two 30-ton double-girder gantry cranes. Our sales and technical teams promptly responded and, through multiple online meetings, gained a thorough understanding of the client’s specific working conditions, usage frequency, span, lifting height and other key parameters. We also provided initial gantry crane equipment selection suggestions.

December 2024–March 2025: Customization of technical solutions and quotations
During this period, the client visited the factory of Henan Dejun Industrial Co., Ltd. in person. Based on our further in-depth communication face by face, we submitted a detailed technical solution and quotation. The core of the solution targeted the client’s pain points and proposed the following customized designs:

• Strengthened structural design: The main beams and legs are made of high-strength steel to ensure structural stability under full load and wind loads.
• Heavy corrosion prevention system: A standard heavy corrosion protection coating scheme is adopted, including special primer, intermediate paint and topcoat, effectively resisting sand erosion and ultraviolet aging.
• Electrical system adaptable to high temperatures: All motors and electrical control components use high insulation grade products, and additional ventilation and heat dissipation devices are installed to ensure continuous and stable operation at temperatures above 50℃.
• Precise control and safety configuration: A variable frequency speed control system is equipped to achieve smooth start and stop and precise positioning. At the same time, multiple safety protections such as overload limiter, limit switch, wind resistance and anti-slip devices are configured.

April–June 2025: Technical Clarification and Contract Negotiation
The client conducted a thorough review of the plan and held multiple rounds of discussions on some technical details and business terms. We demonstrated great patience and professionalism, providing all necessary technical clarifications and similar project cases, and ultimately won the client’s trust.

July 2025: Contract Signing and Project Initiation
Both parties reached an agreement on all terms and successfully signed the purchase contract and made the deposit payment. The project then entered the production and manufacturing stage.
