Introduction
Double Girder EOT Crane is an essential component of any industrial setting. Also known as Electric Overhead Traveling Crane, EOT Crane is a combination of mechanical and electrical equipment that is commonly used for material handling. In this article, we will cover everything about Double Girder EOT Crane, its types, advantages, disadvantages, and applications.
What is a Double Girder EOT Crane?
Double Girder EOT Crane is a type of crane that has two bridge girders instead of one. The two girders are typically connected by a trolley that runs along the bottom flange of the girders. The trolley is supported by a hoist that lifts and lowers the load. Double Girder EOT Crane is designed to provide more lifting capacity, higher hook lift, and increased crane span.
The Advantages of Double Girder EOT Crane
Double Girder EOT Crane offers several advantages, such as high lifting capacity, increased safety, low maintenance, and reliability. Because of its two bridge girders, it can handle heavier loads than Single Girder Crane. The hoist trolley is suspended between the two girders, providing better stability and reducing load swing. Double Girder EOT Crane is also less likely to suffer from structural damage or deflection, which increases safety and reduces maintenance costs.
The Disadvantages of Double Girder EOT Crane
While Double Girder EOT Crane offers many benefits, it is not without its drawbacks. The main disadvantage of Double Girder EOT Crane is its higher cost. The second girder increases the cost of construction and installation compared to Single Girder Crane. Additionally, it requires more space to operate, which can be a problem in smaller facilities.
The Types of Double Girder EOT Crane
Double Girder EOT Crane comes in different types, depending on the application and design. The most common types are as follows:
- Top Running Double Girder EOT Crane: It is the most common type of Double Girder EOT Crane, where the crane runs on a rail installed on top of the runway beams.
- Under Running Double Girder EOT Crane: It is the opposite of the top running crane where the crane runs on the bottom flange of the bridge girders.
- Double Girder EOT Crane with Wire Rope Hoist: It is a specialized crane that is used for high-capacity lifts that require long or heavy load transport.
The Applications of Double Girder EOT Crane
Double Girder EOT Crane is used in a wide range of industries, including:
- Steel Industry: It is used to move heavy steel plates, billets, and coils.
- Automotive Industry: It is used to handle auto parts during the production process.
- Power Plants: It is used for lifting and transporting heavy equipment and materials in power plants.
- Construction Industry: It is used for moving heavy materials and equipment on construction sites.
The Maintenance of Double Girder EOT Crane
To ensure the longevity and safety of Double Girder EOT Crane, regular maintenance is essential. The maintenance should include inspection, cleaning, and lubrication of the crane's different parts. The hoist, rope, hooks, and brakes should be regularly inspected and maintained for wear and tear. To prevent accidents, defective parts should be immediately replaced and repaired.
The Cost of Double Girder EOT Crane
The cost of Double Girder EOT Crane depends on several factors, such as capacity, span, and application. The cost of construction and installation of a Double Girder EOT Crane is generally higher than a Single Girder Crane due to the added complexity in design and construction. However, Double Girder EOT Crane offers more lifting capacity, longer span, and increased safety.
The Installation of Double Girder EOT Crane
The installation of Double Girder EOT Crane should be done by professional and experienced technicians. The installation process involves several steps, such as assembling the crane's components, setting up the runway beams, and connecting the electrical components. The installation process should comply with all safety regulations and guidelines, and a thorough inspection should be conducted after installation.
The Safety of Double Girder EOT Crane
Double Girder EOT Crane is designed to provide a high level of safety during operation. However, proper operation and maintenance are essential to ensure safety. The operator should be properly trained and have a clear understanding of the crane's operation. The crane should be regularly inspected, and any defects should be immediately repaired. Safety features such as overload protection and emergency stop buttons should also be installed to prevent accidents.
