What is a top running overhead crane? Generally speaking, top running overhead crane is the most commonly used crane type which has a fixed track system installed on the top of each runway beam.
The lifting capacity of top running overhead crane will not be limited and it can be manufactured to lift loads from 1 ton to 450 tons. Since the crane is supported by steel support columns or existing concrete steel building support structures, it is very suitable for moving extremely heavy loads.

Why Do You Use A Top Running Overhead Crane System?
- Top running overhead crane rides on rails on top of the runway beams, thus providing more lifting height for buildings with limited headroom.
- The crane can be built with capacities of anywhere from 1 ton to over 400 tons, which is ideal for handling extremely heavy loads. It can also accommodate wider spans.
- The installation and maintenance of the crane is much easier than an underhung crane.
- The crane offers durable performance and excellent safety.
In a word, if higher capacity, higher lifting height and more overhead room are required, a top running overhead crane system is the best option.

Top Running & Under Running Crane, Which One Do You Need?
When it comes to buying a bridge crane, a question that many people usually ask is whether an under running or top running crane is a wise choice for their operations. Of course, you can also find bridge crane systems with other different configurations, but deciding whether to choose a top-running or under-running design can be a key decision.
Several questions you need to answer to help you determine whether a top running or underhung crane system will best fit your facility and your lifting needs:
- Can you utilize the existing support structure or will you build a new support structure?
- Are there preexisting runways in your facility?
- The design and layout of your facility and its ceiling height
- Your lifting requirements, such as load capacity, lifting height and hook approach
- How important is free and clear floor space?
