*Lifting Capacity*	1~32t
*Span*	7.5~28.5m
*Lifting Height*	/
*Working Class*	A3,A4
*Ambient Temperature*	-20~40℃

[ LD Single Girder Overhead Crane Specification ]

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.

Moreover, the crane is designed to be highly stable and secure, even when lifting heavy loads at high elevations.

The Comparison between Top Running Crane and Under Running Crane

The main difference between the two types of cranes is their design and the way they operate. Top-running cranes are more suitable for heavy-duty applications while under-running cranes are better suited for lighter loads and smaller workspaces.

A top-running crane is designed to run on rails that are mounted on top of the runway beams. This type of crane is typically used for heavy-duty applications and can carry loads that are too heavy for an under-running crane.

Single Girder Overhead Crane Manufacturing

An under-running crane, on the other hand, runs on rails that are mounted underneath the runway beams. This type of crane is typically used for lighter loads and is often found in manufacturing and warehouse facilities.

Underslung Overhead Crane Wide Applications

Underslung overhead cranes are a good choice for businesses that have limited headroom or low ceilings. This type of crane is designed to be suspended from the ceiling, which means that it takes up less space than a top-running crane.

Underslung cranes are also a good choice for businesses that need to move lighter loads, as they typically have a lower weight capacity than top-running cranes. They are often used in manufacturing and assembly facilities, where they can be used to move materials and products along an assembly line.

If your business has limited space or needs to move lighter loads, an underslung overhead crane may be a good choice.
