What is a overhead bridge crane?
Gantry cranes are a type of crane built atop a gantry, which is a structure used to straddle an object or workspace. They are also called portal cranes, the "portal" being the empty space straddled by the gantry. Dgcrane is professional material handling equipment manufacturer and servicer with largest production in global. Provide you with overhead crane, gantry crane, electric hoist, etc. of safe, reliable and efficient crane solutions and services.Welcome to inquiry dgcrane. The terms gantry crane and overhead crane are often used interchangeably, as both types of crane straddle their workload. The usual distinction drawn between the two is that with gantry cranes, the entire structure is usually wheeled. By contrast, the supporting structure of an overhead crane is fixed in location, often in the form of the walls or ceiling of a building, to which is attached a movable hoist running overhead along a rail or beam. Further confusing the issue is that gantry cranes may also incorporate a movable beam-mounted hoist in addition to the entire structure being wheeled, and some overhead cranes are suspended from a freestanding gantry.

They are comparatively rare. Few were built that way, many were other types of Cranes that were propped up on concrete blocks, as was done with an old Steam Crane in Williamsport, Pa I used to see every day walking to and from school in the so-called roaring junkyard ( so called by high noise level) it had a wooden cab ( except for the boiler and running gear) and a vertical boiler, common on small and medium cranes.

How to Know When You Need Gantry Cranes?
Gantry cranes have been a fundamental part of large construction projects for decades. They are also useful in smaller applications, especially if they have been equipped with rubber wheels instead of running tracks. There are times when gantry cranes are exactly what you need for your project. What is a Gantry Crane? A gantry crane is a large piece of equipment that spans the width of a project site and provides lifting power for the heaviest items. Gantry cranes look like scaffolding with rope and pulley lifting devices. They are usually found at large construction sites or ship building locations. Gantry cranes are the most efficient way to lift very heavy objects into place with the least amount of effort or energy. They are uniquely beautiful to watch as they perform their heavy lifting tasks in a seemingly effortless manner. How Gantry Cranes are Commonly Used The most famous gantry cranes have been used to build large ships for the military and shipping industry. Some gantry cranes have been retired and are on public display because of their massive design and the impact they have had on ship building. Gantry cranes are also useful for building tall structures, like office buildings or apartment complexes. Some gantry cranes are designed to be mobile, which makes them perfect for lifting extremely heavy objects during projects that are not expected to last for months at a time. There are even gantry cranes that have wheels so that they can be moved more easily. Gantry Cranes for Smaller Workshops Though gantry cranes are designed to handle very large and heavy items for large projects, they can also handle smaller heavy items inside workshops. One of the most useful applications for these smaller gantry cranes is in automotive shops. Car engines are extremely heavy and difficult to manipulate, but they occasionally need to be removed from the car to be properly repaired. A small gantry crane can lift the engine from the car easily and allow the mechanic full access to the parts and sections of the engine that need to be worked on. The lifting capacity of gantry cranes makes them ideal for automotive repair shops.

The Benefits of Gantry Cranes?
There is no other type of equipment that is as efficient and useful on a construction site or work station than a gantry crane. Gantry cranes lift both large and small objects by hoisting them into the air and moving them to their proper location. These items are usually larger and heavier than any group of workers could lift on their own, thus, making the use of one of these crane essential to complete their work. There are a few different types of these cranes to choose from that customize to each specific use in construction. There are both fixed and adjustable gantry cranes. Fixed cranes have a set height that they cannot deviate far from or exceed. These are commonly used in work spaces that need to lift very specific items and infrequently. When a site does not have much lifting to do, this would be the most cost effective option. Having a lift that does not include the extra bells and whistles of an adjustable gantry crane will save them both time and money. Workers will be spending less time adjusting the crane and doing the lifts and can concentrate on completing their task at hand. However, an adjustable gantry crane can be a lifesaver in heavy traffic construction sites. The height of these types of cranes can be adjusted much farther than fixed cranes and in increments of three feet at a time. This means that this crane can meet any work site’s needs and fit into tighter spaces if needed. This makes the completing the task more flexible and easier on the workers. Some of these types of cranes can even adjust the span and width of the crane to fit into unique working conditions and can be narrowed down to fit through even the smallest of spaces, such as hallways and doorways. These cranes have proven to be an essential part of the construction industry and have improved the quality of work that has been done over the years. Gantry cranes are a piece of equipment that no work site should ever be without if they have large items to move.
