The Basics of Gantry Cranes

   Gantry cranes, often referred to as overhead cranes or bridge cranes, are a type of material handling equipment used for lifting and moving heavy loads in various industrial settings. They consist of a horizontal beam (the bridge) supported by two uprights (the legs), forming a gantry-like structure.

Types of Gantry Cranes

   Gantry cranes come in different configurations to suit specific needs. Understanding the types of gantry cranes is essential for choosing the right one for your construction project.

   1. Single Girder vs. Double Girder

• Single Girder Gantry Cranes:These cranes have a single bridge beam and are typically more lightweight and cost-effective. They are ideal for applications where the load capacity is moderate and the span is relatively short.
• Double Girder Gantry Cranes:In contrast, double girder gantry cranes feature two bridge beams running on top of the supporting legs. This design provides increased stability and higher load capacities. Double girder cranes are often used for heavy-duty applications and longer spans.

   2. Mobile vs. Stationary

•       - Mobile Gantry Cranes:Mobile gantry cranes are equipped with wheels, allowing them to be moved to different locations within a facility. These cranes are highly versatile and suitable for situations where materials need to be lifted and transported across various points in a workspace.
•       - Stationary Gantry Cranes:Stationary gantry cranes are fixed in one location. They are often used when the lifting and transportation tasks are limited to a specific area within a facility. These cranes provide stability and can handle heavy loads efficiently.
