رافعة مزدوجة العارضة محكمة تكافؤ الفرص

ما هي الرافعة ذات العارضة المزدوجة EOT؟?

العارضة المزدوجة EOT (السفر الكهربائية العلوية) crane is a robust, overhead lifting system designed for heavy-duty material handling in industrial environments. على عكس single girder EOT crane, it features two parallel main girders spanning the workspace, supported by end carriages that travel along elevated runways. This structure enables it to handle significantly higher loads—typically ranging from 10 طن ل 500 tons or more—making it ideal for demanding lifting tasks where precision, استقرار, and durability are critical.

Powered by an electric motor, the double girder EOT crane operates via a hoist (mounted on a trolley) that moves along the girders, combined with runway travel for full coverage of the workspace. It is widely recognized as a reliable solution for streamlining operations in factories, المستودعات, and heavy industries.

Key Features of Double Girder EOT Cranes

Double girder EOT cranes stand out for their advanced design and performance, offering the following advantages:

• 1. سعة حمولة عالية: With two main girders distributing weight evenly, these cranes handle heavier loads (10t–500t+) compared to single girder models, suitable for lifting machinery, لفائف الصلب, ومكونات كبيرة.
• 2. Enhanced Stability: The dual-girder structure minimizes deflection during lifting, ensuring stable operation even with maximum loads, reducing the risk of sway or imbalance.
• 3. نطاق العمل الممتد: The trolley runs along the full length of the girders, while the crane travels along the runway, providing comprehensive coverage of the workspace (customizable span lengths available).
• 4. بناء متين: Made from high-strength steel (Q235B or Q355B), the girders and components resist wear and corrosion, ضمان عمر خدمة طويل (15–20 years with proper maintenance).
• 5. تكوينات قابلة للتخصيص: Adaptable to specific needs—options include speed control, أنظمة مكافحة التأثير, التحكم عن بعد, explosion-proof designs, and specialized hoists (على سبيل المثال, magnetic, خطاف, or grab).
• 6. Efficient Operation: Electric drives deliver smooth, precise movement (رفع, عربة, and crane travel speeds adjustable), reducing downtime and improving workflow efficiency.

Technical Parameters of Double Girder EOT Crane

Structural Components of Double Girder EOT Crane

A double girder EOT crane consists of several key components working together to ensure reliable lifting:

1. العوارض الرئيسية

Two parallel box-type or I-beam steel girders forming the primary load-bearing structure, spanning the workspace.

2. نهاية العربات

Located at both ends of the main girders, equipped with wheels that travel along the runway rails, enabling the crane to move horizontally.

3. رفع & عربة

The hoist (electric winch with hook, مغناطيس, or grab) is mounted on a trolley, which travels along the main girders via rails, allowing vertical lifting and horizontal movement along the span.

4. Runway System

Elevated rails (installed on columns or walls) that guide the crane’s end carriages, defining the crane’s travel range.

5. النظام الكهربائي

يشمل المحركات (رفع, عربة, crane travel), لوحات التحكم, الكابلات, وأجهزة السلامة (overload sensors, محولات الحد) to manage power and operations.

6. كابينة السائقين

Double Girder EOT Crane Manufacturing Process

Industry Applications of Double Girder EOT Cranes

Double girder EOT cranes are indispensable in industries requiring heavy lifting and precise material handling:

• 1. فُولاَذ & علم المعادن: Lifting steel coils, سبائك, and forged parts in mills and foundries.
• 2. تصنيع: Moving machinery, molds, and large components in automotive, الفضاء, and heavy equipment factories.
• 3. التخزين & الخدمات اللوجستية: Loading/unloading heavy cargo, stacking bulk materials in ports, freight yards, and distribution centers.
• 4. بناء: Lifting precast concrete, عوارض فولاذية, and construction machinery on job sites.
• 5. طاقة & التعدين: Handling generators, محولات, and mining equipment in power plants and mines.
• 6. بناء السفن: Assembling ship components and lifting heavy marine equipment.

FAQs About Double Girder EOT Cranes

س 1: What’s the difference between a double girder and single girder EOT crane?

أ: تحتوي الرافعات ذات العارضة المزدوجة على عارضتين رئيسيتين, تقدم قدرة تحميل أعلى (10t+) والاستقرار, suitable for heavy-duty use. Single girder cranes have one girder, ideal for lighter loads (up to 20t) and smaller workspaces.

Q2: How often should a double girder EOT crane be maintained?

أ: عمليات التفتيش الروتينية (الشيكات اليومية لارتداء, monthly lubrication) and annual professional maintenance are recommended to ensure safety and extend service life.

س 3: Can double girder EOT cranes be customized for special environments?

أ: نعم. Options include explosion-proof designs (for hazardous areas), الطلاءات المقاومة للتآكل (for chemical plants), and high-temperature resistance (for foundries).

س 4: What safety standards do double girder EOT cranes comply with?

أ: They adhere to international standards such as ISO, فيم, من, وإدارة السلامة والصحة المهنية, with built-in safety features like overload protection and emergency stops.

س 5: How long does it take to install a double girder EOT crane?

أ: Installation time varies by size and complexity—typically 2–4 weeks for standard models, with longer timelines for custom or large-span systems.
