Двухбалочный кран EOT

Что такое двухбалочный кран EOT??

Двухбалочный EOT (Электрическое перемещение над головой) crane is a robust, overhead lifting system designed for heavy-duty material handling in industrial environments. В отличие от 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 тонн до 500 tons or more—making it ideal for demanding lifting tasks where precision, стабильность, 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, склады, и тяжелая промышленность.

Key Features of Double Girder EOT Cranes

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

• 1. Высокая грузоподъемность: With two main girders distributing weight evenly, these cranes handle heavier loads (10t–500t+) compared to single girder models, suitable for lifting machinery, стальные рулоны, и крупные компоненты.
• 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. Extended Working Range: 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. Прочная конструкция: Made from high-strength steel (Q235B or Q355B), the girders and components resist wear and corrosion, обеспечение длительного срока службы (15–20 years with proper maintenance).
• 5. Настраиваемые конфигурации: Adaptable to specific needs—options include speed control, противораскачивающие системы, Дистанционное управление, взрывозащищенные конструкции, and specialized hoists (НАПРИМЕР., magnetic, крюк, or grab).
• 6. Эффективная работа: Electric drives deliver smooth, precise movement (подъемник, тележка, 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. Основные балки

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

2. Концевые каретки

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

3. Подъемник & Тележка

The hoist (electric winch with hook, магнит, 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. Электрическая система

Включает двигатели (подъемник, тележка, crane travel), панели управления, кабели, и устройства безопасности (overload sensors, ограниченные переключатели) to manage power and operations.

6. Кабина водителя

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. Сталь & Металлургия: Подъемные стальные рулоны, слитки, and forged parts in mills and foundries.
• 2. Производство: Moving machinery, формы, and large components in automotive, аэрокосмическая, and heavy equipment factories.
• 3. Склады & Логистика: Loading/unloading heavy cargo, stacking bulk materials in ports, грузовые площадки, and distribution centers.
• 4. Строительство: Подъем сборного железобетона, стальные балки, and construction machinery on job sites.
• 5. Энергия & Добыча: Handling generators, трансформаторы, and mining equipment in power plants and mines.
• 6. Судостроение: Assembling ship components and lifting heavy marine equipment.

FAQs About Double Girder EOT Cranes

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

А: Двухбалочные краны имеют две основные балки., предлагая более высокую грузоподъемность (10т+) и стабильность, suitable for heavy-duty use. Single girder cranes have one girder, ideal for lighter loads (up to 20t) and smaller workspaces.

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

А: Плановые проверки (ежедневная проверка износа, monthly lubrication) and annual professional maintenance are recommended to ensure safety and extend service life.

Q3: Can double girder EOT cranes be customized for special environments?

А: Да. Options include explosion-proof designs (для опасных зон), антикоррозийные покрытия (for chemical plants), and high-temperature resistance (for foundries).

Q4: What safety standards do double girder EOT cranes comply with?

А: They adhere to international standards such as ISO, Женский, ОТ, и OSHA, with built-in safety features like overload protection and emergency stops.

Q5: How long does it take to install a double girder EOT crane?

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