The Popularity of Gantries
The use of gantries to load and off-load large and heavy freight is becoming increasingly popular and in response to that increasing need, more and more different types of gantries are becoming available. One of the larger gantry crane manufacturer companies is Ellsen of China and their current range of gantries is very impressive. When you look at their list of gantries available, you will see that they are divided into two categories which are heavy lift and small lift. The heavy lift category lists gantries which are capable of lifting loads from 10 tons to 200 tons whilst the small lift category has a variety of gantries that can lift from 1 ton to 10 tons.
In the heavy lift list there are Cantilever gantries, Double Girder Gantries, Portable gantries, Rail mounted gantries, rubber tired gantries, truss gantries and others whilst in the small lift list there are a variety of different gantries that can lift differing amounts.
Cantilever Gantry Crane
This is perhaps the biggest gantry on their list and is capable of lifting up to 200 tons. It gets its name due to the fact that it has 2 cantilevers on the bridge which reduces stress on the legs of the gantry.
Double Girder Gantry Crane
This gantry can either be used as a single girder gantry in which case an electric hoist can be used or as a double girder gantry without an electric hoist.
Portable Gantry Crane
As this gantry can only lift 10 tons, it could be in either list but the advantage of this gantry s that, as its name suggests, it can be taken down easily and so can be operated in several locations.
Rail Mounted Gantry Crane
As this gantry is rail mounted, it is very easy to operate but before you buy one, you will have to decide what type of rails you want it to be mounted on.
Rubber Tyred Gantry Crane
This is the ideal gantry for use on unusual surfaces as it has been designed with rubber tires especially for that reason.
Truss Gantry Crane
The Truss gantry has been specifically designed with high winds in mind and so is often the gantry of choice for ports along a windy coast.
These gantries basically have a similar design but come in different sizes allowing them to lift either 1 ton with the smallest ones or as much as 10 tons with the largest ones. These are ideal for use in auto mechanic shops or similar businesses.
Although there are already a large number of different gantries to choose from, their increasing popularity will mean that new types will probably appear with regularity and so always check online for any new types that have come on the market. Choosing the right gantry for the type of work you have can save a lot of stress at a later time. Always remember when using gantries of any type, to take all the relevant safety measures.
