HD single girder top running overhead crane

Top Running Overhead Crane

As an important lifting equipment, top running overhead crane is designed to travel on the top of the runway system which is supported by factory building or engineered columns. Such kind of crane can be used on many work occasions, such as maintenance workshop, casting or metallurgy plant, garage, assembly workstation and equipment processing factory. For different occasions, cranes are different.

For work places with limited headroom, top running overhead cranes can provide greater lifting height than under-hung cranes because top running cranes travel on rails on the top of the beams. Compared with under running cranes, top-running cranes are typically larger and better choices for heavier lifting capacity applications especially when the loads are heavier than 20 tons.

Classifications of Top Running Overhead Crane

Top running crane comes into two types in Ellsen, and they are single girder top running crane and double girder top running crane. Single girder crane works with CD, MD hoist as its lifting mechanism, and the hoist is hung underneath the crane main beam and travels along the I-steel. The crane travels along the runway rail. There are electric motors providing power for the crane and hoist traveling.

Double girder crane is designed with trolley traveling along the track on top of the main beams, and it can provide better hook height during lifting operations compared with single girder crane. This crane can be used to meet heavy load needs. For some special working conditions, the crane should be processed and equipped with more protections measures to meet the special requirements; if it is applied in metallurgical or casting plant, some parts of the crane should be with heat insulation layer, and it requires higher security; if it is applied to the work ambient with explosive or flammable gas and dust, the crane should be processed with explosion proof protection according to the corresponding standard.

Why Choose Ellsen Top Running Overhead Crane

You can select a top running overhead crane with either single girder or double girder style to meet your work needs. It is clearly known that single girder crane has lighter lifting capacity than double girder one. When it comes to the choice of the crane, you have to know the  weight of the material that is going to be lifted, the lifting height of the material, the span and what work duty and work speed you want for the crane. The design and production of the crane you need will depend on the above information. Another thing you need to consider is that the crane you select should have reliable safety protections. Choosing the wrong crane will cause a lot of problems for your business in the long run.

Top running overhead crane systems include easier installation and wide availability of parts, and the wheels of a top-running crane are easier to service, as the crane does not have to be suspended from above. Ellsen is a professional top running overhead crane manufacturer in China and has produced many cranes for different customers all over the world.
