Introduction to Double Girder Overhead Cranes

A double girder overhead crane is a robust material handling equipment designed to lift and transport heavy loads in industrial settings. Engineered with two parallel main girders, it delivers superior stability and load-bearing capacity compared to single girder models, making it the go-to choice for heavy-duty applications such as steel mills, उत्पादक संयंत्र, गोदामों, और निर्माण स्थल. Whether you need to move machinery, कच्चा माल, or finished products, our double girder overhead cranes combine precision, टिकाऊपन, and safety to optimize your workflow.

What is a Double Girder Overhead Crane?

A double girder overhead crane is a type of bridge crane consisting of two horizontal main girders supported by end trucks (or end carriages) that run along elevated rails (रनवे) mounted on building columns or standalone structures. The crane’s lifting mechanism—typically a hoist or trolley—is mounted on a trolley that travels along the length of the main girders, allowing 360° coverage of the workspace below.

भिन्न सिंगल गर्डर ओवरहेड क्रेन, which rely on a single main beam, double girder designs distribute weight more evenly, enabling them to handle much heavier loads (often up to 500 tons or more). This makes them essential for industries requiring frequent heavy lifting, where reliability and safety are non-negotiable.

Key Features of Double Girder Overhead Cranes

Our double girder overhead cranes are built to excel in demanding environments. Here are their standout features:

• 1. उच्च भार क्षमता: Designed to handle heavy loads from 10 tons up to 500 टन, making them ideal for heavy-industry applications.
• 2. सुपीरियर स्थिरता: Two main girders distribute weight evenly, reducing sway and ensuring stable operation even with maximum loads.
• 3. Extended Span Options: Available with spans from 10 मीटर को 35 मीटर की दूरी पर, adaptable to large workspaces like warehouses or factory floors.
• 4. परिशुद्धता नियंत्रण: Equipped with advanced hoisting and trolley mechanisms for smooth, accurate positioning of loads—critical for delicate or high-value materials.
• 5. टिकाऊ निर्माण: Made from high-strength steel with anti-corrosion coatings, ensuring long-term performance in harsh conditions (उदा।, उच्च तापमान, धूल, or moisture).
• 6. बढ़ाया सुरक्षा: Integrated safety features include overload protection, आपातकालीन रोक बटन, सीमा स्विच, and anti-collision devices to prevent accidents.
• 7. अनुकूलन योग्य डिज़ाइन: Can be tailored with optional extras like remote control, frequency inverters for variable speed, or specialized hooks for unique load types (उदा।, , coils, कंटेनरों).

तकनीकी निर्देश

Structure of a Double Girder Overhead Crane

A double girder overhead crane consists of several key components working together to ensure efficient lifting and movement:

1. मुख्य गर्डर

मुख्य गर्डर

Two parallel steel beams (गर्डरों) that form the bridge structure. They bear the load of the trolley and the lifted material, requiring high strength and rigidity.

2. अंत ट्रक (अंत गाड़ियाँ)

अंत ट्रक

Mounted at both ends of the main girders, these house the wheels and motors that drive the crane along the runway rails.

3. ट्रॉली

ट्रॉली

A movable unit that travels along the top or bottom of the main girders. It carries the hoist and is powered by its own motor for horizontal movement.

4. उभाड़ना

उभाड़ना

The lifting mechanism, including a crane drum, wire rope/cable, और क्रेन हुक. It is responsible for raising and lowering loads, with options for electric or hydraulic operation.

5. विद्युत व्यवस्था

विद्युत व्यवस्था

Includes motors, control panels, स्विच, and wiring to power and operate the crane, ट्रॉली, और फहराओ.

6. सुरक्षा उपकरण

उठाने की ऊँचाई सीमक

Overload limiters, travel limit switches, आपातकालीन रोक प्रणाली, and anti-sway devices to ensure safe operation.

अक्सर पूछे जाने वाले प्रश्न: डबल गर्डर ओवरहेड क्रेन

Q1: What’s the difference between a double girder and single girder overhead crane?

ए: Double girder cranes have two main girders, offering higher load capacity (10+ टन) और स्थिरता, making them suitable for heavy-duty use. Single girder cranes have one main girder, हल्के हैं, and better for lighter loads (तक 10 टन) in smaller workspaces.

Q2: Which industries use double girder overhead cranes?

ए: They are widely used in steel mills, automotive manufacturing, शिपयार्ड, निर्माण स्थल, गोदामों (for heavy pallet handling), and power plants.

Q3: How often should a double girder overhead crane be maintained?

ए: Routine inspections (daily checks for wear, स्नेहन) and professional maintenance (every 6–12 months) are recommended to ensure safety and longevity.

Q4: Can double girder cranes be customized for specific applications?

ए: हाँ. We offer customizations for load capacity, अवधि, उठाने की ऊँचाई, नियंत्रण प्रणाली, and specialized attachments (उदा।, magnets for metal handling, grabs for bulk materials).

Q5: Are double girder overhead cranes compliant with international safety standards?

ए: Our cranes meet ISO, फेम, and OSHA standards, with built-in safety features to ensure compliance with global industrial regulations.
