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.
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 gantry crane components together, providing stability for safe and efficient lifting.
There are several types of gantry cranes, each with features and advantages for particular applications. Below, we’ll look at the main types and what each is used for.
A full gantry crane has two sturdy legs running on rails or tracks, enabling it to span large work areas with ease. These cranes are commonly used in environments like shipping yards, rail yards, and large construction sites to handle substantial materials or containers.
Full gantry cranes come in two primary configurations: single girder and double girder. A single girder gantry crane has one main horizontal girder along which the hoist travels. A double girder crane has two girders, which allows for greater lifting capacity and higher stability.
What makes a semi-gantry crane different? Unlike full gantry design, semi gantry cranes have one leg on a rail and the other side attached to a building or structure. They are often found in locations with limited space, as they save ground area and work well in factories or storage yards where one side is close to a wall or other support.
What is RTG crane? Rubber tyred gantry cranes, or RTG cranes, are mobile cranes on rubber wheels, commonly used in manufacturing plant, shipping yards, construction sites, and outdoor storage yards to stack and move various loads. Their mobility on tires allows them to maneuver across factory yards without needing tracks, giving them flexibility in handling materials.
What is an RMG crane? Rail mounted gantry (RMG) cranes operate on fixed rails. They’re often used in ports and intermodal yards for stacking containers with high precision. Since they run on rails, RMG cranes provide stability and are ideal for large, organized storage areas with high stacking requirements.
What is goliath crane? Also known as a portal crane, a goliath crane is a large gantry crane typically used in heavy industries like shipbuilding, where substantial lifting capacity is essential. They can lift extremely heavy loads, making them perfect for assembling ship parts, handling large precast concrete, or other large-scale manufacturing.
Now that we’ve covered the different types of gantry cranes, let’s explore what gantry cranes are used for across various industries:
