Single Girder EOT Crane: A Complete Guide to Features, Benefits, and Applications

1. Introduction

A Single Girder EOT (Electric Overhead Travelling) Crane is an essential material handling solution used across various industries. Designed for efficiency and reliability, these cranes are widely employed in manufacturing units, warehouses, and heavy-duty industrial applications to lift and move loads safely and effectively.

In this comprehensive guide, we will discuss Single Girder EOT Cranes, their components, benefits, applications, technical specifications, selection criteria, and maintenance tips. Whether you are planning to install a Single Girder EOT Crane in your facility or simply want to learn more, this article covers everything you need to know.

2. What Is a Single Girder EOT Crane?

 

A Single Girder EOT Crane consists of a single bridge girder supported on two end trucks. It operates using an electric hoist that moves along the girder to lift and transport materials. These cranes are widely used in industries where moderate lifting capacity is required.

 

3. How Does a Single Girder EOT Crane Work?

 

• The crane operates on an overhead runway system, allowing horizontal movement across the workspace.
• The electric wire rope hoist or chain hoist lifts and lowers the load with precision.
• Movement is controlled via a pendant or radio remote control system.
• The bridge travels along the runway beams using end carriages equipped with wheels.

4. Components of a Single Girder EOT Crane

A Single Girder EOT Crane comprises several key components, each playing a crucial role in its operation:

1. Bridge Girder – The primary horizontal beam supporting the load.
2. End Carriages – Support the bridge and facilitate movement along the rails.
3. Electric Hoist – Lifts and lowers loads, commonly using a wire rope hoist.
4. Trolley Mechanism – Allows the hoist to move along the girder.
5. Control System – Includes a pendant control or wireless remote control system.
6. Long Travel Mechanism – Enables the crane to move across the length of the workspace.
7. Electrical Panel – Houses electrical components, including circuit breakers and contactors.
