Understanding Gantry Cranes: Types, Features, and Applications
If you’re exploring heavy-duty lifting solutions, understanding what is a gantry crane or what is a portal crane can help you determine if it’s the right solution for your operation. These cranes are versatile lifting systems widely used across construction, manufacturing, and shipping to handle large loads with ease. Whether you’re in the early stages of researching crane equipment or looking to compare types for a specific application, this guide covers the essentials – from the types and uses of gantry cranes to their key benefits and structure, helping you make an informed decision for your lifting needs.
What is a Gantry Crane?
A gantry crane is a lifting system where the crane’s hoist and trolley move along a bridge (or girder) supported by two or more legs. These legs are often fixed to rails or set on wheels, allowing the crane to straddle a workspace and lift materials precisely. The term “gantry” typically refers to the overarching structure that holds the crane components together, providing stability for safe and efficient lifting.
