We have supplied top running eot cranes to various industries, helping businesses optimize their material handling processes. Here are some notable project cases:
If you’re planning to install a top running overhead crane in your facility, it’s crucial to thoroughly evaluate your building structure and available space. These factors play a key role in ensuring optimal crane performance, safety, and long-term operational efficiency.
A top running bridge crane operates on runway beams mounted on the building’s support structure. Therefore, the building must be capable of handling the additional loads imposed by the crane system, including:
You should conduct structural analysis to ensure that the building can accommodate these loads without compromising stability.
The installation of a top running overhead crane often requires dedicated support columns and runway beams. If the building lacks adequate structural support, additional steel columns may need to be installed, impacting overall project costs. Key factors to assess include:
Top running overhead bridge cranes typically offer a higher hook height compared to under running cranes, making them ideal for applications requiring maximum vertical lifting space. However, it is essential to consider:
The available horizontal and vertical space must accommodate smooth crane movement. Factors to evaluate include:
Space planning should account for:
Our team of experts is ready to assist you in designing the right type of overhead crane top running systems that meet your facility’s unique structural and spatial requirements. Contact us today to discuss your project and receive a customized recommendation.
Maximized Headroom and Lifting HeightSince the overhead crane runs on top of the runway beams, it offers higher clearances beneath the crane’s bridge, which is beneficial for lifting taller loads or working in facilities with low ceiling heights.
Heavy-Duty CapabilityThese cranes are typically designed for heavier loads and more demanding environments. The design allows for greater load capacities because the system distributes the weight across the top of the structure, reducing the strain on individual components.
Longer SpanWith top running bridge cranes, you can achieve longer spans between the crane’s runway beams. This enables the crane to cover a larger area of the facility, making it suitable for larger industrial spaces. A longer span also improves the crane’s flexibility and efficiency in moving materials over a wide range.
Better Stability and DurabilityThe crane running top typically requires a strong support structure that is separate from the building’s framework. This ensures that the crane operates safely and efficiently without relying on the building itself for support. This independent structure provides enhanced stability and durability, making them suitable for large industrial environments.
Our cranes are designed to meet the demands of heavy-duty lifting, and we provide comprehensive support at every stage, from planning and installation to after-sales service. Here’s how we support your overhead lifting needs with our top running crane systems:
We will work closely with your team to assess your facility layout, lifting capacity, and operational requirements. Based on this assessment, we will design a customized crane that maximizes efficiency, space utilization, and safety.
We offer professional installation services to ensure your crane is set up correctly, minimizing any risks and ensuring it operates at peak performance.
Once your crane is installed, it’s crucial that your team knows how to operate the overhead crane safely and efficiently. We provide comprehensive training to your operators, ensuring they are fully equipped to handle the crane and any lifting challenges that come their way.
We provide robust after-sales service to ensure your top running EOT crane continues to perform reliably over its lifetime.
Whether you’re lifting heavy loads in a steel mill, manufacturing plant, or warehouse, our cranes provide the reliability, performance, and support you need to keep your operations running smoothly.

When selecting an overhead crane system, one of the most important decisions is choosing between a top running and under running crane. Both systems have distinct advantages and applications, depending on your facility’s structure and lifting requirements. Here are under running and top running overhead crane definitions to understand what they are, as well as a comprehensive comparison of these two crane types to help you make an informed decision.
A top running crane travels on rails mounted on top of the runway beams, which are supported by columns or building structure.
An under running crane, also known as an underhung crane, is suspended from the bottom flange of the runway beams, which are attached to the building roof structure.
Both top running and underhung cranes offer unique benefits depending on your operational needs. Generally, a top running bridge crane is ideal if you need to lift heavy loads, require greater hook height, or have the necessary infrastructure for support. On the other hand, if you’re working with a limited budget, need a light duty crane, or want to optimize floor space without extra support columns, an under running crane is the better option.
