A Comprehensive Guide to Over Head EOT Cranes

Over Head Electric Over Head Traveling (EOT) cranes are essential equipment in various industries, including manufacturing, construction, and logistics. These cranes facilitate the lifting and transportation of heavy loads with precision and efficiency. This comprehensive guide will cover everything you need to know about Over Head EOT Cranes, including their types, components, working principles, safety measures, and maintenance.

Introduction to Over Head EOT Cranes

Electric Over Head Traveling (EOT) cranes are a type of Over Head crane used primarily in industrial environments. These cranes are powered by electricity and run on an Over Head runway system to transport heavy loads horizontally within a designated area. Over Head EOT Cranes are known for their efficiency, reliability, and ability to handle a wide range of lifting tasks.

Types of Over Head EOT Cranes

EOT cranes come in various configurations to suit different operational needs. The two main types are Single Girder Over Head EOT Cranes and Double Girder Over Head EOT Cranes.

Single Girder Over Head EOT Cranes

Single Girder Over Head EOT Cranes have a single bridge girder that supports the trolley and hoist. These cranes are typically used for lighter loads and shorter spans. They are cost-effective and easier to install, making them ideal for small to medium-sized facilities.

Double Girder Over Head EOT Cranes

Double Girder Over Head EOT Cranes feature two bridge girders that provide additional strength and stability. These cranes are suitable for heavy-duty lifting tasks and longer spans. They offer higher lifting capacities and can accommodate larger and heavier loads compared to single girder cranes.

Key Components of Over Head EOT Cranes

Understanding the key components of Over Head EOT Cranes is essential for effective operation and maintenance.

Bridge

The bridge is the main structural component that spans the width of the area being serviced. It supports the trolley and hoist and provides the path for horizontal movement.

Hoist

The hoist is the lifting mechanism of the crane. It consists of a motor, drum, wire rope, and hook. The hoist can be either electric or manual, with electric hoists being more common due to their efficiency and ease of use.

Trolley

The trolley carries the hoist along the bridge, enabling horizontal movement. It moves along the rails of the bridge and allows the hoist to be positioned precisely above the load.

Runway

The runway is the track system on which the bridge travels. It is mounted on the building structure and supports the weight of the crane and the load. The runway typically consists of rails or beams.

Number of Parts in Over Head EOT Cranes

Over Head EOT cranes are composed of numerous parts, each playing a critical role in the crane's overall functionality. Below is a comprehensive list of the primary parts found in an Over Head EOT crane:

• Bridge Girder: 1 (Single Girder) or 2 (Double Girder)
• End Trucks: 2
• Hoist Mechanism: 1 (varies by design)
• Trolley: 1 per hoist
• Runway Rails: 2
• Control System: 1
• Power Supply System: 1
• Braking System: 1
• Bumpers: 4
• Limit Switches: 1-2 per motion
• Wire Rope or Chain: 1 per hoist
• Hook: 1 per hoist
• Load Block: 1 per hoist
• Load Weighing System: 1 per hoist

Working Principles of Over Head EOT Cranes

EOT cranes operate on a simple yet effective principle. The hoist, attached to the trolley, lifts the load using a wire rope or chain. The trolley moves along the bridge, and the bridge itself travels on the runway, allowing the load to be positioned accurately within the designated area. The entire system is controlled by an operator using a pendant, radio remote, or a cabin control system.

Basic Operation Steps

1. Hoisting: The hoist lifts the load.
2. Trolley Movement: The trolley moves the load along the bridge.
3. Bridge Travel: The bridge moves along the runway to position the load.

How Over Head EOT Cranes Work

Over Head Electric Over Head Traveling (EOT) cranes are widely used in industrial settings for lifting and transporting heavy loads. The operation of these cranes involves several key components working in harmony to ensure precise and efficient load handling. Here's a simple step-by-step explanation of how Over Head cranes work:

1. Lifting the Load:
   • The hoist (attached to the crane) lifts the load using a wire rope or chain. The hoist is powered by an electric motor.
2. Horizontal Movement:
   • The trolley, which carries the hoist, moves along the bridge girder. This movement positions the load horizontally within the crane's span.
3. Bridge Travel:
   • The entire bridge (which includes the bridge girder and end trucks) moves along the runway rails. This allows the load to be transported over a larger area within the facility.
4. Positioning the Load:
   • The operator uses a control system (pendant, radio remote, or cabin control) to precisely position the load at the desired location.
5. Lowering the Load:
   • The hoist lowers the load to the ground or onto another surface safely and smoothly.
6. Safety Measures:
   • Limit switches prevent the hoist, trolley, and bridge from moving beyond preset limits.
   • Bumpers absorb energy if the crane reaches the end of the runway or bridge.
   • Braking systems ensure controlled stopping of the hoist, trolley, and bridge movements.
7. Power Supply:
   • The crane receives power through a power supply system, which can include conductor bars or festoon systems that deliver electricity to the crane’s motors and control systems.

Summary

The hoist lifts the load, the trolley moves the load along the bridge, and the bridge moves along the runway rails. The operator controls these movements to transport and position the load precisely, with various safety mechanisms ensuring safe operation.
