A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. Cranes are distinguished from other lifting machines by their ability to move the load freely in three dimensions. Cranes are commonly used in the construction industry and in the manufacturing of heavy equipment.
The term “cranes” can be traced back to the Greek word for crane, κράνος (kranos), which was related to the Greek word for crow or raven, κόρας (koras). The first known use of the term is in Homer’s Odyssey, where Odysseus is instructed to build a large wooden vessel called a kranaion. In the Middle Ages, the word “crane” referred to a device used to hoist materials onto ships.
Today there are many different types of cranes, each designed for a specific purpose. One of the most common types of crane is the overhead gantry crane. Overhead gantry crane are often used in warehouses and factories to move heavy loads around. They typically consist of a bridge that spans between two supports, with a trolley that runs along the bridge. The trolley is used to hoist and lower loads, and the crane can be moved along the length of the bridge to position the load.
Gantry cranes come in a variety of sizes and capacities, and can be customized to meet the specific needs of your facility.

Types and Uses of Overhead Gantry Cranes
Overhead gantry cranes are one of the most versatile pieces of equipment in any work environment. They come in a wide variety of sizes and configurations to suit many different applications. Here is a guide to the most common types of overhead gantry cranes and their uses:
1. Container gantry cranes
Container gantry cranes are the most common type of overhead gantry crane. They are used extensively in seaports, airports, and intermodal terminals to load and unload containers. These cranes have a horizontal beam that straddles the width of a shipping container. They also have a trolley with a hook that runs along the beam to lift and move containers.
2. Bulk gantry cranes
Bulk gantry cranes are used to handle bulk materials such as coal, iron ore, and gravel. They have a similar design to container gantry cranes, but they are fitted with specialised grabs or buckets to grip and move the bulk materials. These cranes are often used in mines, ports, and power plants.
3. Truss gantry cranes
Truss gantry cranes are designed for heavy-duty applications such as construction and shipbuilding. They have a strong horizontal beam made from multiple trusses or girders. This provides them with the strength to lift very heavy loads. The trolley on a truss gantry crane also has a much higher lifting capacity than other types of overhead gantry cranes.
4. C-hook gantry cranes
C-hook gantry cranes are used for handling long, cylindrical loads such as steel coils and pipes. They have a horizontal beam with a trolley that is fitted with a C-shaped hook. This hook can rotate 360 degrees, making it easy to load and unload the cylindrical loads. C-hook gantry cranes are commonly used in steel mills and pipeyards.
5. Goliath gantry cranes
Goliath gantry cranes are the largest type of overhead gantry crane. They are used for very heavy duty applications such as loading and unloading ships. Goliath gantry cranes have a horizontal beam that straddles the width of a ship. They also have a trolley with a large hook that runs along the beam. The hook is used to lift cargo onto the ship. Goliath gantry cranes are usually found in port areas.
Design Considerations for Overhead Gantry Cranes
Design Considerations for Overhead Gantry Cranes
When it comes to choosing an overhead gantry crane for your facility, there are a number of things you need to take into account to ensure you make the best possible choice. In this blog, we’ll run through some of the key design considerations for overhead gantry cranes, so you can be sure you’re making the right decision for your business.
One of the first things to consider is the span of the crane. This is the distance between the innermost supports on either side, and will determine how much weight the crane can safely lift. It’s important to choose a span that’s appropriate for the types of loads you’ll be lifting, as an overloaded crane can be very dangerous.
The next thing to consider is the lifting capacity of the crane. This is the maximum weight the crane can lift, and again, it’s important to choose a crane that’s suitable for the loads you’ll be lifting. Overloading a crane can be very dangerous, so it’s important to make sure you choose a crane with a suitably high lifting capacity.
The height of the crane is another important consideration. This is the distance from the ground to the top of the crane, and will determine how high up the crane can reach. It’s important to choose a height that’s appropriate for the applications you’ll be using the crane for.
The last thing to consider is the track gauge of the crane. This is the distance between the rails that the crane runs on, and will determine how wide the crane can be. It’s important to choose a track gauge that’s appropriate for the facility you’ll be using the crane in.
These are just a few of the key design considerations for overhead gantry cranes. Be sure to take all of these things into account when choosing a crane for your business, to ensure you make the best possible choice.
Overhead Gantry Crane Load Requirements
In any factory or manufacturer that utilises heavy materials handling equipment, an overhead gantry crane is an essential and integral piece of machinery. As its name suggests, an overhead gantry crane is a crane that runs along an overhead rail, and is used to move heavy materials and products from one place to another.
Due to the heavy nature of the materials they are designed to move, gantry cranes must be designed and manufactured to exacting standards, in order to ensure safety and reliability. When designing an overhead gantry crane, there are a number of key considerations that must be taken into account.
The first and arguably most important consideration is the maximum weight capacity that the crane must be able to safely lift and transport. This will be dictated by the heaviest item or material that the crane will need to regularly lift and move. It is important to overestimate the weight capacity required, as attempting to lift a load that is too heavy for the crane could result in serious damage to both the crane and the load itself.
The next consideration is the maximum liftingheight required. This will be dictated by the tallest item or material that the crane will need to regularly lift and move. Once again, it is important to overestimate the lift height required, as attempting to lift a load that is too tall for the crane could result in serious damage to both the crane and the load itself.
The span of an overhead gantry crane is the distance between the two outermost points of the crane (the points at which the crane rails are mounted). The span will dictate how far the crane can reach from one side of the factory or manufacturing unit to the other. It is important to ensure that the span of the crane is sufficient for the widest load that it will need to regularly lift and move.
The speed of an overhead gantry crane is dictated by the amount of time that it takes for the crane to complete one lifting cycle. The lifting cycle is the time taken for the crane to lower a load from one point to another. The speed of the crane will need to be slow enough to ensure that the load can be safely and accurately positioned at the required destination, but fast enough to avoid causing delays in production.
These are just a few of the key design considerations that must be taken into account when designing an overhead gantry crane. If you are in need of an overhead gantry crane for your factory or manufacturing unit, then be sure to consult with a reputable and experienced designer and manufacturer who will be able to create a crane that meets your specific requirements.
