What is a Single Girder Overhead Crane?
Single Girder overhead cranes, also known as bridge cranes or electric overhead travelling (EOT) cranes, are essential in modern industries. The Yuantai single girder overhead crane is a type of crane that is commonly used in industrial settings for lifting and moving heavy loads. This type of crane features a single girder, which is the main horizontal beam that supports the lifting mechanism. In Yuantai Crane Company, a single-beam overhead crane is usually equipped with a CD or MD Wire Rope Hoist.

Single Girder Overhead Crane Components
The components of a single girder overhead crane include the main girder, end trucks, hoist trolley, and hoist. The main girder is typically made of steel and is designed to support the weight of the load. The end trucks are located on either end of the main girder and contain the wheels that allow the crane to move along the runway beam. The hoist trolley is attached to the main girder and holds the hoist, which is responsible for lifting and lowering the load.
Crane Working Principle
A single girder overhead crane works by using the hoist to lift and move heavy objects. The hoist is attached to the load and is controlled by an operator using a control pendant or Remote Control. The operator can move the crane along the runway beam to position it over the load, and then use the hoist to lift the load and move it to a new location
The crane’s single horizontal beam (the “girder”) is supported by two end trucks, which move along a runway beam. The hoist and trolley are mounted on the girder and can move along the length of the crane. The hoist is used to lift and lower the load, while the trolley moves the load horizontally along the length of the crane. The crane can be operated manually or with a motorized system, depending on the specific needs of the application.
Single Girder Overhead Crane Design Benefits
While limited in terms of capacity and span, the single girder crane design offers several advantages and benefits, making it the ideal solution for many applications.
They can be integrated into the building design, saving costs on the runway structure. The hoist trolley can go underneath the runway, providing the best end approach, and the low headroom design, especially with notched bridge beams, takes advantage of the runway depth.
The single girder crane design allows for a freestanding workstation bridge crane system that is exceptionally rigid due to the connection of columns to headers, and the headers to the runway. The system is also capable of interlocking with another crane or monorail.
Less expensive due to a simpler crane design, reduced freight costs, simplified and faster installation, and less material for the bridge and runway beams. Lower loads on the building structure or foundations due to a reduced deadweight. In many cases, it can be supported by existing roof structures without the use of additional support columns.
Single-beam cranes are easier to install and maintain. Because they only require one bridge beam, they are more compact and lighter than a double girder crane, saving you money on materials, freight, installation, and maintenance.
Key Features of a Single Girder Overhead Crane
Compact design. Because it only has a single girder, it requires less space than other types of cranes. This makes it ideal for use in facilities where space is limited. Additionally, the single girder design allows for greater hook height, which means it can lift loads higher than other types of cranes.
The bridge frame of the single-girder bridge crane runs longitudinally along the tracks laid on both sides of the elevated frame, and the hoisting trolley runs laterally along the track laid on the bridge frame, forming a rectangular working range, which can make full use of the space under the bridge frame to lift materials, Not hindered by ground equipment.
Applications of Single Girder Overhead Crane
Its unique design offers several advantages over other types of cranes, including greater hook height and a smaller footprint, which make the single crane ideal for lifting and moving heavy loads in industrial settings. It can be used in a wide range of applications, from manufacturing and construction to warehousing and logistics. It can also be customized to meet specific requirements, such as lifting capacity, span, and height.
