An overhead traveling crane, also known as a bridge crane or suspended crane, is a type of heavy-duty material handling equipment that runs along a runway system built into a building’s support structure.
These cranes are designed to lift and transport heavy loads with ease, making them an essential part of manufacturing and other industries where large, heavy items need to be moved from one location to another.
Types of Overhead Traveling Cranes
Overhead traveling cranes come in various types, each suited for different applications and environments. Some of the most common types include:
Single Girder Bridge Cranes
Single girder bridge cranes are the most common type of overhead traveling crane. They consist of a single beam supported by two end trucks. These cranes are ideal for light to medium duty lifting applications and are commonly used in workshops, warehouses, and factories.
Double Girder Bridge Cranes
Double girder bridge cranes are more robust and can handle heavier loads than single girder bridge cranes. They consist of two beams supported by end trucks and are commonly used in heavy-duty lifting applications such as steel mills and foundries.
Gantry Cranes
Gantry cranes are similar to bridge cranes, but instead of being supported by a building’s support structure, they are supported by legs that run along the ground. This makes them ideal for outdoor applications, such as shipping yards and construction sites.
Components of an Overhead Traveling Crane
An overhead traveling crane consists of several components, including:
Bridge
The bridge is the main horizontal beam that spans the width of the runway system. It supports the hoist and trolley and travels along the runway system, allowing the crane to move from one location to another.
Hoist and Trolley
The hoist and trolley are responsible for lifting and lowering the load. The hoist is the device that attaches to the load, while the trolley moves the load horizontally along the bridge.
End Trucks
The end trucks are the components that support the bridge and allow it to move along the runway system. They are typically mounted on wheels or tracks and are powered by electric motors.
Advantages of an Overhead Traveling Crane
There are several advantages of using an overhead traveling crane, including:
Increased Efficiency
Overhead traveling cranes can move large, heavy loads with ease, reducing the time and effort required to move materials around a facility.
Improved Safety
Overhead traveling cranes are designed to lift and transport heavy loads safely and efficiently, reducing the risk of injury to workers.
Increased Flexibility
Overhead traveling cranes can be customized to suit specific applications, making them ideal for a wide range of industries and environments.
