Underslung Overhead Crane vs Top-running Overhead Crane

When it comes to moving heavy loads efficiently and safely in industries, two popular choices stand out: the underslung overhead crane and the top-running overhead crane. These cranes play a vital role in various sectors, from manufacturing plants to warehouses. But how do you know which type of crane suits your needs? Let's break down the differences and help you make an informed decision.
Both underslung and top-running overhead cranes are designed to lift and transport heavy objects using an elevated track system. However, their configurations and applications differ significantly.

Underslung Overhead Crane: Hanging Low for Efficiency

Imagine a crane with its beam positioned below the track on which it moves. This is the underslung overhead crane. This design choice makes it ideal for spaces with limited vertical room. It's like the crane is giving you a little extra headroom while it works. Underslung cranes are commonly found in smaller workshops, where space is at a premium.

1. Design: An underslung overhead crane is characterized by its configuration where the crane's girder (the horizontal beam) is positioned below the runway beams. The hoist and trolley move along the bottom flange of the girder.
2. Installation: Underslung cranes are typically installed beneath existing roof structures. They are commonly used when there's limited vertical space available, as the crane doesn't interfere with the available headroom.
3. Applications: Underslung cranes are commonly used in situations where the building's structural design or space limitations prevent the installation of a top-running crane. They are suitable for tasks that need precision and moderate load capacities.
4. Headroom: Since the crane's girder is situated below the runway beams, underslung cranes provide more usable vertical space above the crane itself. This is beneficial when there are height restrictions in the facility.
5. Load Capacity: Underslung cranes are suitable for lighter to moderate load capacities. They are often used in workshops, warehouses, and smaller manufacturing units.

Top Running Overhead Crane: Reaching New Heights

On the other hand, the top-running overhead crane has its beam sitting atop the runway beams. While it might seem counterintuitive, this design is perfect for handling heavy loads. It's like having the crane's muscles right where they're needed. These cranes are often seen in larger industrial settings, capable of carrying substantial weight across longer spans.

1. Design: In a top-running overhead crane, the crane's girder is positioned atop the runway beams. The hoist and trolley move along the top flange of the girder.
2. Installation: Top-running cranes need more vertical space because of the positioning of the girder and trolley above the runway beams. They are commonly used in larger industrial settings with ample headroom.
3. Applications: Top-running cranes are widely used in heavy industries such as steel manufacturing, automotive, aerospace, and shipping. They are designed to handle heavy loads and provide efficient coverage for larger work areas.
4. Headroom: Due to the positioning of the crane's components, top running cranes generally have less available vertical space above the crane itself compared to underslung cranes.
5. Load Capacity: Top-running cranes are capable of handling heavier load capacities. They are commonly found in heavy manufacturing industries, construction sites, and other places where large lifting capacity is required.

Choose the Most Suitable Overhead Crane

In the end, the decision between an underslung and top-running overhead crane hinges on your unique needs. If space is tight and lighter loads are the norm, the underslung crane offers efficiency. On the other hand, if you're dealing with heavy loads and can afford vertical room, the top-running crane provides robust lifting capabilities.

 

Evaluate your workspace, lifting requirements and budget before making a choice. If you're still unsure, contact us and we'll provide design drawings and a quote for your situation. Keep in mind that whether you're bottom-hung or top-hung, these cranes will lighten your load and simplify your operations.

Why Custom a Crane Solution?

At Yuantai, we know that there is no "one size fits all" in the lifting field. Universal cranes are suitable for general factories, warehouses, etc. Besides, different applications have different needs for cranes. For example, steel industries often lift steel plates, so need electromagnetic cranes. Ports and docks often need to load ore, gravel, and other bulk goods, so need to grab bucket cranes. Chemical dangerous places often need to carry flammable and explosive materials, so need explosion proof cranes.

So, we provide customized cranes according to the special needs of our customers. Custom crane solutions offer many benefits in a variety of applications：
