Single Girder Overhead Crane
Simple Design, Supreme Solution

The single girder overhead crane or single girder bridge crane consists of one girder beam supported on each side by an end truck. The trolley and hoist are most commonly underhung, which means they run on the bridge's bottom flange. In terms of design, the bridge can be either top running or under running. p

For many applications and industries, single girder bridge cranes are the most cost-effective lifting solution. Single girder cranes use less material and are more compact and lightweight than double girder cranes, resulting in significant material, freight, and installation cost savings. Furthermore, because only one bridge beam is required, these systems typically have less deadweight, allowing them to use lighter runway systems and tie into the existing building support structure.

A single girder overhead crane is a type of light duty overhead crane that has three mechanisms: a lifting mechanism, a crane traveling mechanism, and a trolley traveling mechanism. The lifting mechanism is made up of an electric hoist, en electric wire rope or electric chain hoist, a pulley, and a hook. The steel structure of a single girder overhead crane is made up of the main girder frame and the end carriage frame; the main girder is mostly made up of the I beam and steel plates, specifically the top flange, web, and I beam; and crossed Stiffeners are settled within the main girder box. The performance of the single girder overhead crane directly related to the steel structure's safety and dependability.

Introduction to Single Girder Bridge Cranes

Do you require a single-girder overhead crane or single girder bridge crane? To ensure that you buy a crane system that meets your needs today and tomorrow, you must consider a number of critical factors. When purchasing a single-girder overhead crane, you should consider safety, dependability, efficiency, and other factors. Here are the most important factors to consider when purchasing a crane for your specific application.

What‘ s a Single Girder Overhead Crane?

What’s a single girder overhead crane ?A single-girder overhead crane is a type of bridge crane that consists of two or more overhead runways built into the building's support structure, with the girder (the bridge) running the length of the crane bay between the runways.

End trucks at each end of the girder move the girder and hoist forward and backward along the length of the runways. The trolley and hoist are typically routed along the girder's underside.

Overhead cranes with a single girder have the following advantages:

Less expensive due to less material used in production and a simple trolley design
The most cost-effective option for light and medium-duty applications.
Reduce the load on your building's structure and foundation.
It is simple to install, service, and maintain.

Advantages vs. Disadvantages of Single Girder Overhead Crane

Comparing withdouble girder overhead crane, the single girder overhead crane has the following advantages and disadvantages:

Because there is only one cross girder in a single girder overhead crane, the weight is less when compared to two girders in a double girder overhead crane.
The hoisting mechanism is simple because it is a standard hoist, and the modular weight of the hoist is much lower than that of its counterpart in double girder cranes.
The platform of a double-girder overhead crane is not possible in a single-girder overhead crane.

Because of the lighter weight of the single girder eot crane, the crane price is lower, and the supporting structure, such as gantry girders and columns, as well as the overall building size, can be reduced.

Limitations of Single- Girder Overhead Crane

Because there is no platform or accessibility, maintenance is difficult.
When compared to a similar double-girder overhead crane, the lifting height is lowered.

How Yuantai has conquered these above disadvantages

On one side of the single girder overhead crane, Yuantai is installing a repair platform. This maintenance platform houses the control panel. As a result, it's simple to use and maintain.The platform is also constructed in such a way that the electric hoist may be maintained from it.

Yuantai has a Low Head Room Hoist available. As a result, the disadvantage of a single girder overhead crane is eliminated since the height of the hoist is reduced, allowing the single girder overhead crane to give greater lifting height than a crane with no low headroom hoist.

Why single girder girder crane cannot be solution all the times?

Yuantai has completed single girder cranes with capacities of up to 30 tons. Overhead cranes with a single girder are not recommended at this height.

Also, the maximum span for a single girder overhead crane that we have built is 25 meters.

Applications of Single Girder Overhead Travelling Cranes

Single-beam cranes are commonly used for lifting goods in a variety of settings, including workshops, factories, warehouses, and stock yards, as well as for material transportation in industries such as manufacturing and warehouse transportation.

Top Runing VS. Underslung, Single Girder VS. Double Girder

Top Running V.S. Under Running

A top-running, single-girder overhead crane haves its end carriages or end beams move on top of each runway beam. Each runway beam has an under-running, single-girder overhead crane (often referred to as an underhung crane).

Top-running single-girder cranes have a higher weight capacity than under-running single-girder cranes, which is the main advantage of single girder overhead crane. When positioned on ceiling trusses or roof structures, single-girder cranes, on the other hand, maximize floorspace (eliminating the need for runway support columns).

Single girder vs Double Girder

Single Girder Overhead Crane

Double Girder Overhead Crane

Single Girder EOT Crane have only 1 No. Main Girder across the span.

Double Girder EOT Crane have 2 Main Girders across the span.

It consist of Electric Hoist travelling on lower flange of Main Girder and not required rail for cross traveling.

It consist of a crab mechanism travels above both girders run over cross travel rails with platform to maintain all parts of crab.

Single Girder Cranes generally have no platform for maintenance,or have 2 small platform for LT mechanism maintenance.

Double Girder Cranes have both sides platform across the main girders for maintenance purpose and platform for crab maintenance.

Single Girder cranes does not consist Under bridge light.

Double Girder cranes have under-bridge light for illusion to work in night.

Single Girder cranes have Flange mounted motors and vertical gearboxes for MH,CT and LT movements.

Double Girder Eot crane have foot mounted motors with Horizontal gearboxes.

Single Girder cranes can be operated through pendent and Radio Remote but they can not operated through operating cabin.

Double Girder cranes can be operated by pendent ,Radio Remote and operating Cabin,all operation mode is available..

Single Girder cranes do not consist Electro Hydraulic thruster brakes due to its constriction,there is DC Disc Brake used in all motions.

Mostly DG EOT Cranes have EHT Brakes and a combination of EHT+DC Disc Brakes used,there is no limitation of using Brakes.

In single Girder cranes we used snap action limit switch which initate by a wire rope guide for limiting Hoists movement in up and down motion.

In DG EOT Cranes we used Rotary Limit switch which have a geared system to calculate hook travelling and limit it in up and down movement accordingly,there is an additional limit switch also placed as gravity limit switch to double secure limit switch working and protection.

Single Girder eot cranes used mostly upto 20 mtr span and 25T capacity for normal working.

Double Girder eot cranes can be used from 1Ton to more than 500 Ton as per requirement.

Single Girder cranes used mostly in light applications for handling normal material with standard working conditions.

Double Girder eot Cranes used in all type of applications for handling material and even in very critical atmosphere like cement,steel and oil and Gas.

Single Girder cranes designed with 4 wheel arrangement in LT End carriage so have higher wheel load and required heavy gantry girder comparatively for same capacity.

Double Girder Eot cranes can be designed with 8 wheel arrangement so wheel load at a particular point is lesser so gantry girder structure will be light comparatively.

These cranes is difficult for maintenance point of view but cheaper at price basis.

These cranes are easy in maintenance but costly at price basis.
