Eot Crane Parts Names and Their Functions

Published: 10 Aug 2025

Electric Overhead Traveling (EOT) cranes are vital lifting solutions used in manufacturing, warehouses, shipyards, and many other industrial settings. These cranes are designed to move heavy loads with precision and safety, reducing manual effort and improving operational efficiency. To understand how they work, it’s important to explore the various EOT crane parts and their functions that make these machines reliable and effective.

What is an EOT Crane?

An EOT crane is an electrically powered overhead crane that moves along elevated runways, allowing horizontal movement of loads across a facility. Controlled through a cabin or remote system, it can lift, move, and lower heavy materials with precision. These cranes are available in single-girder and double-girder designs, depending on the lifting capacity and operational requirements.

Important EOT Crane Parts Name and Their Functions

Bridge

The bridge is the main structural frame of the crane that spans across the working area. It provides support for the trolley and hoist, enabling them to move from one end of the runway to the other.

Columns

Columns are vertical support structures that hold runways at a required height. They provide stability and strength to handle heavy loads.

Runway

The runway consists of tracks fixed on top of columns, guiding the bridge’s movement along the facility. It allows the crane to cover large work areas efficiently.

Hoist

The hoist is an essential component that lifts and lowers loads during operation. It is equipped with a drum, motor, and a lifting medium like wire, rope, or chain.

End Effectors

End effectors are attachments connected to the hoist that directly handle the load. They can be hooks, grabs, magnets, or other specialized lifting tools.

Reinforced-Steel Cable

The reinforced-steel cable, also known as wire rope, carries the load during lifting. Its strength and durability are essential for safe and long-term use.

Trolley

The trolley holds the hoist and moves horizontally along the bridge. This allows precise positioning of the load.

Electric Motor

The electric motor powers the crane’s lifting and movement operations. It converts electrical energy into mechanical force for efficient performance.

Brakes

Brakes provide stopping power and hold the load in position when lifting or moving is stopped. They are essential for safety and precision control.

Limit Switches

Limit switches prevent over-travel of the hoist or trolley by automatically stopping motion when set limits are reached.

Gearboxes

Gearboxes control the crane’s speed and torque, ensuring smooth operation and efficient power transmission.

Rail Sweepers

Rail sweepers remove debris from the crane’s runway rails, preventing obstructions and maintaining smooth travel.

Control Systems

Control systems allow operators to maneuver the crane precisely. They can be pendant controls, wireless remotes, or cabin-based systems with joysticks.

End Trucks

End trucks are the wheeled assemblies at both ends of the bridge. They carry the bridge along the runway rails.

Bumpers & Rubber Stops

These components absorb impact and prevent damage if the crane or trolley reaches the end of its travel path.

Wheels and Modules

Wheels enable the crane to move smoothly along the runway rails, while wheel modules house and support them.

Hook

The hook is the most common load-handling device. It securely holds and lifts materials, often with a safety latch to prevent accidental drops.

Busbar or DSL System

The busbar or Down Shop Lead (DSL) system provides continuous electrical power to the crane while allowing free movement along the runway.

Conclusion

Each EOT crane part plays a vital role in ensuring smooth, safe, and efficient lifting operations. From the bridge and runway to the hoist, control systems, and safety components, every element is engineered for reliability. By understanding the names and functions of EOT crane parts, operators and maintenance teams can ensure the optimal performance and longevity of these powerful machines.

FAQs

What is the DSL full form in EOT crane?

DSL in EOT crane stands for Down Shop Lead, the power supply line for crane movement.

What is an EOT crane hoist?

It’s the lifting unit of the crane, used to raise or lower loads using a drum, motor, and rope or chain.

What is the meaning of EOT crane?

EOT crane means Electric Overhead Travelling crane, used for material handling in industries.

What is the end carriage of an EOT crane?

The end carriage houses the wheels and connects the bridge to the runway, enabling movement.

What are the main EOT crane types?

The main types are single girder and double girder EOT cranes, based on load and span needs.

What is an EOT crane girder?

The girder functions as the key horizontal beam, ensuring stable support for both the trolley and the hoist.
