Top running overhead crane is a kind lifting solution widely used in various industrial settings, including warehouses, manufacturing plants, steel mills construction sites and more. The top running cranes operate on elevated tracks mounted on the building’s structure, allowing for efficient horizontal movement across large areas.
In this article, we will introduce top running overhead crane types, specifications, projects, combination solutions, advantages and how they can optimize material handling processes.
Top Running Overhead Crane Types
The top running overhead crane can be divided based on girder configuration. Aicrane has different models of top running single girder crane and top running double girder crane for sale.
Single Girder
Single Girder Top Running Overhead Crane
A single girder top running overhead crane is a type of crane with a single horizontal beam that spans the width of the runway. This top running single girder crane is designed for lighter to moderate lifting applications. The single girder configuration allows for a more compact and lightweight design, making it a cost-effective solution for facilities with lower lifting capacity requirements.
Top running single girder crane models: AQ-LD, AQ-HD, AQ-LDZ and AQ-LB.
Double Girder
Double Girder Top Running Overhead Crane
A double girder top running overhead crane features two horizontal beams that run parallel to each other, providing increased strength and stability. This design allows the top running double girder crane to handle much heavier loads compared to single girder cranes.
Double girder cranes are suitable for heavy-duty applications in industries such as steel manufacturing, foundries, and shipyards. The added structural support and higher lifting capacity make double girder top running cranes ideal for tasks that involve lifting large and cumbersome loads over an extended span.
Top running double girder crane models: AQ-QD, AQ-QDX, AQ-LH, AQ-NLH, AQ-QZ, AQ-QCL and AQ-YZ
