An overhead crane mainly consists of 1 main girder, 2 end carriages, 1 electric hoist, electric device, etc.

Advantages of top running single girder overhead crane

With box girder design, the single girder crane is with good design with strong rigidity.
With pendant or remote control, the single girder overhead crane is with good usability, very convenient in operaiton and strong commonality
Steady travelling with speed adjusting function
Wide selection of electric ovheread hoists, including, electric wire rope hoist and electric chain hoist, etc. .

Overhead crane components

On single main girder.

The crane girder is made by high quality I steel and high quality u-shaped slot into composition. End girder is welded with rectangular tubes or good steel.
The girder can be assembled and adjusted easily and rapidly.
Compact structure which are small and light.
The specially made wheels are light and widely used.
Smoothly moving, effectively braking, long service life,

Features of of LD types top running single girder overhead crane with overhead electric hoist

This crane lifting capacity is 500kg-20ton, span 3m-31.5m, lifting height 3m-30m.
Standard lifting& travelling speed is single speed, also can be designed with double speed.
The electric hoist is usually CD MD electric wire rope hoist, also can be replaced by electric chain hoist.
For there are different standard power supplies in different countries, the crane can be designed according to the power supply in client's workshop, eg: China standard power is 380 voltage 50Hz 3phase. (Single phase is not available.)
There are some necessary protecting devices on LD single girder overhead crane, eg: lifting & travelling limit switch, overload limiter, anti-collision buffers, etc.
Lifting limit switch is for lifting protecting, prevent the hook from knocking the hoist.
Travelling limit switch is from crane travelling protecting, prevent the crane from knocking the rail end.

Application of single girder electric hoist crane

The top running single girder overhead crane is used to for general material handling in various environment, such, as, factory, ware house, stockyard, etc. However, the LD series of top running overhead cranes are banned to be used in some dangerous environment, such as, combustible environment and explosive environment, where the LB type explosion proof top running single girder overhead crane will be adopted instead.

How to Get Your Customized Single Girder Overhead Crane

Single Girder Overhead Crane Drawing for you to confirm your crane specifications

First, please confirm the range of weight of material the crane is required to lift. It'd be best if client can elaborate on the majority of weight and frequency of lifting. Example below:

Client A wants to purchase an overhead crane to lift steel plate, the steel plate weighs 1ton, 2 ton, 3ton, 3.2 ton, then the lifting capacity required is 3.2ton.

Reminder that the working frequency and load-up condition also influence the choice of overhead crane. LD single girder overhead crane's working classification is ISO M3 or M4, which can meet most basic lifting requirements. But if you need a crane to lift mostly 3ton material on a frequent basis, we will recommend you increase the rated capacity to 5 ton, to avoid overuse.

Second, it's the lifting height. Usually it depends on the clear height of the workshop and height of bracket (for steel structure workshop) or column (for cement concrete building). If there is height limit in your building, we can choose low headroom type electric hoist for you according to the working condition and your request.
Third, let's talk about span. Span is distance between two crane rail centers, usually less 1-1.5m than inside width of the building.

You can install a LD single girder overhead crane on the existing bracket or column in building. If the building doesn't have existing bracket or column, or can't support the whole overhead crane load, extra steel column and rail support beam (ie. runway beam or bearing beam) for the overhead crane are needed.

Next is about speed. We have single speed, double speed, also can design non-standard speed. If you don't confirm how to choose, we can help you choose suitable speed according to the working condition.

Until this step, a basic overhead crane solution can be confirmed. If you also need bus bar system, crane rail and crane rail support beam please provide the travelling length of the overhead crane.
