How is a Gantry Crane Different from a Bridge Crane?

by Mahi Sheth HR Manager
While browsing through the topics of overhead cranes, the most common query that I have come across is the difference between a Gantry crane and a bridge crane. Even though they belong to the same parent type of crane (overhead crane), there is a huge difference between the two. In this article, I have tried to put the difference between the two cranes in the easiest way that could have been possible. Have a look.

1.    Structure

  • Bridge Cranes: They have both a single as well as double girder bridge arrangement. They operate on the hook movement of the 3 axes. This enables the bridge crane to become flexible enough to enable the placement of loads easily.

  • Gantry Cranes: They have a bridge that is supported by 2 rigid steel legs of A-frame. These legs rest on the floor and are equipped with casters. This makes it possible for the crane to move in different directions easily.

2.    Lifting Mechanism

  • Bridge Cranes: The lifting mechanism of the bridge crane is characterized by a rail that is elevated for applications whose requisite is off-floor processes. The beam of this crane is suspended from the runway attached to the ceiling or walls of the building. It has a permanent fixture with a lifting area and a fixed span.

  • Gantry Cranes: They basically provide overhead lifting with the help of its legs and casters that run both with and without a track. It can be easily moved through the workspace, disassembled for hassle-free relocation, and lifts objects without exerting any pressure on the building.

3.    Lifting Capacity

  • Bridge Cranes: They can lift weight ranging between ½ ton to 100 tons. In addition to this, they can span hundreds of feet as well.

  • Gantry Cranes: A majority of gantry cranes can lift capacities ranging from 1.2 ton to 15 tons. For outdoor use, they can also be made into oversized capacities.

4.    Areas of Application

  • Bridge Cranes: They are suitable for industries such as clean rooms, hazardous locations, facilities like food service, water treatment plants, etc.

  • Gantry Cranes: They are used for moving shipping containers, loading and unloading the containers, construction of ship’s engines, etc.

5.    Pricing

  • Bridge Cranes: The price range of a bridge crane starts from $15,000 and can be as much as $100,000 depending on its specification and overall size.

  • Gantry Cranes: They are usually less in price as compared to the bridge cranes. Their cost usually starts from $2,000.

With this, we come to an end to the differences between a bridge crane and a gantry crane. We hope that by now all your doubts regarding the two cranes are clear.
