In this detailed guide, we will cover everything about Double Girder EOT Cranes, including their features, benefits, applications, technical specifications, selection criteria, maintenance tips, and frequently asked questions. If you're considering investing in a Double Girder EOT Crane, this guide will help you make an informed decision.

1. What is a Double Girder EOT Crane?

A Double Girder EOT Crane consists of two parallel bridge girders that support the lifting mechanism, offering greater strength and durability compared to Single Girder EOT Cranes. These cranes are designed to handle heavy loads efficiently across large workspaces.

2. How Does a Double Girder EOT Crane Work?

• Operates on an overhead runway system, enabling vertical & horizontal movement.
• Utilizes a Rope Drum Mechanism mounted on a trolley to lift and transport loads.
• Controlled via pendant control, remote control, or cabin operator system.
• Runs on end carriages equipped with wheels for smooth travel along the runway.

3. Components of a Double Girder EOT Crane

A Double Girder EOT Crane consists of the following major components:

1. Double Bridge Girders – Provides strong structural support for heavy loads.
2. End Carriages – Houses the wheels that enable crane movement along the runway.
3. Hoist & Trolley Mechanism – Moves along the bridge girders, lifting and lowering loads.
4. Control System – Includes pendant, radio remote control, or cabin-based operation.
5. Electrical Panel – Houses motor control and safety mechanisms.
6. Long Travel Mechanism – Enables smooth horizontal movement across the workspace.
7. Safety Features – Overload protection, emergency stops, limit switches, and anti-collision systems.
