Types of gantry cranes for constructions site to improve your efficiency & safety, box girder & truss gantry crane, rail travelling & rubber tyred gantry crane, etc.
In a busy construction site, there are various different types of heavy equipment and machinery being used. Tower crane is one of the most frequently used cranes. Besides, the gantry cranes of various types and designs are also widely used in different construction sites, such as, subway, highway, bridge constructions, etc.
In the following, the main types of construction site gantry cranes are presented for your reference, such as, double girder gantry crane, truss type gantry crane, and rubber typred gantry cranes.
Gantry crane systems are available in a wide range of configurations and can be used in a wide range of applications and construction site.
The fact that gantry cranes can be used for so many different materials and loads which is one of their obvious features. From small portable cranes to massive full gantry crane systems used in bridge and subway construction. In the following the main types of gantry cranes and why they are so well suited to their purpose or material handling conditions are presented for your reference.
Heavy Full Gantry Crane System
A full gantry crane system is one of the most popular gantry crane configuration. This type of gantry crane is made up of two supporting legs, one on each side, that move in a straight line along two rails on the floor. The floor rails are embedded in the floor's top surface which can ensure the travelling of gantry crane but at the same time ensures the travelling of other machinery at the working site or construction , such as forklifts, carts, and trucks to roll over without causing any disruption. Single girder gantry crane and double girder gantry cranes are optional for your application.
Semi-Gantry Crane System
A semi-gantry crane system can be designed with one leg riding on wheels or rails and the other side using a runway system connected to building columns. Depending on the circumstances, this could be used in doors and outdoors. The main advantage of such a single leg gantry crane system is that it saves a significant amount of floor (work) space and, unlike a overhead bridge crane, does not require two runways cross the workshops or facilities.
Light Portable Gantry Crane System
A portable gantry crane is much smaller and lighter in weight than the previous two types of gantry crane systems. It is not limited in a fixed location and is moved around facility using casters or rubber wheels to hoist and support various materials and load types. This movable gantry system's portability allows it to be available when required but stored when not in use, saving space and improving floor space flexibility.
Light Adjustable (Telescoping) Gantry Crane System
An adjustable gantry crane has variable dimensions to accommodate different working environments. This includes movable placement along the I beam (gantry span), movable height, and movable base width. The system also has the advantage of being much more maneuverable around the work area.
Because gantry cranes are used for such a huge variety of applications and their load capacity can range from one to900 tons , there are many different versions of the four primary classifications of gantry crane. These include:
Because gantry cranes are used for such a wide range of applications and have load capacities ranging from500kg to 900 tons, there are numerous variations of the above 4 main types of gantry cranes. These are some examples:
With the rapid growth of the economy, population, and motor vehicles, many cities have developed a serious 'urban disease' - a large traffic jam. Subways are created. The subway is becoming an important mode of transportation in many urban areas because it is comfortable, fast, and convenient.
With the rapid development of subways, construction equipment and machinery, particularly construction cranes are playing an increasingly important role in subway construction. Yuantai Crane has extensive experience and a large number of project cases involving subway construction gantry cranes.
Gantry Crane for Subway Construction
For subway tunnel construction, a subway gantry crane is used for slag handling is used. This gantry crane is primarily responsible for the subway tunnel's construction, lifting the dregs excavated by the shield excavator to the ground. Subway slag gantry crane characteristics include variable span and improved crane utilization.

The gantry crane for railway construction is specifically designed for moving and transporting concrete span beams and bridges during railway construction. To handle railway beams, users can use two 500t (450t) cranes or one 1000t (900t) crane with two lifting points.
The main girder, rigid and flexible supporting legs, travelling mechanism, lifting mechanism, electric control system, hydraulic system, driver cabin, railing, ladder, and walking plat are all part of this railway construction gantry crane.
Gantry Crane for Railway Construction
The large capacity gantry crane is specially designed for the span beam/bridge moving and transport for railway construction.
Features of railway construction gantry crane：
Gantry crane for high way & bridge erection is ideal for general loading and unloading, as well as lifting and handling tasks in highways, bridges, and other construction sites. It is an important lifting equipment in bridge construction because of its light structure and high wind resistance.
It's a type of gantry crane. Its main beam structure is of the box, truss, and hollow box variety. There are three types of legs: box, truss, and steel tube. It has two lifting points or two sets that can use it. An electric hoist serves as the auxiliary hook, and an I-beam running hoist is welded beneath the main beam. It is possible to use a secondary hook.
The truss gantry crane has a latticed structure with a small windward area, light weight, and good lifting ability, among other characteristics.Truss gantry cranes are ideal for outdoor applications where lifting devices can be used without the expense of supporting steel-work.
This highway construction gantry crane is used to lift the concrete beam or bridge onto the highway construction supports.Because the legs of this gantry crane can land on the supports, there is no pressure or damage to the highway beam/bridge.
Truss girder gantry crane for high way construction
Standard specification of gantry cranes
Features of truss gantry cranes for highway constructions
This highway construction gantry crane is used to lift the concrete beam or bridge onto the highway construction supports. It is made up of a girder longitudinal flat car, girder components, a support system, a crane transverse, a longitudinal shift system, a hydraulic system, and an electric control system, among other things.
Yuantai Crane is developing various highway cranes to meet the various working and use requirements, such as skew bridge, curved bridge, dislocation bridge, heavy beam, variable beam, double-direction construction, tunnel construction, and so on.
Rubber-tired gantry cranes are moved flexibly by their own rubber tires to complete the hoisting, handling, and loading of large cement concrete, blocks and road sections on construction sites.Rubber tired gantry crane are widely used for subway, bridge and high ways construction sites, etc.

Features of tyred gantry crane for constructions site
Jib cranes are a type of crane that consists of a portable horizontal jib arm attached to a vertical mast or tower. Jib cranes can lift and move materials in semicircles (180 degrees) or full circles (360 degrees) (360 degrees). Jib cranes typically have a hand-powered rotation and traverse motion, as well as an electric-powered or hand-powered lift motion.
Lift and move materials in semi-circles (180 degrees) or full circles (360 degrees) (360 degrees)
Best for: Repetitive and unique tasks in smaller work areas such as factories, warehouses, and outdoor working site, or civil construction site, so on.
Bulk-handling Cranes
The bulk handling cranes are similar to standard cranes, but instead of a standard hook, they use a two-piece hinged bucket known as a clamshell grab or clamshell bucket to lift bulk cargoes such as coal or mineral ore.
Tower Cranes
Tower cranes are usually attached to the sides of structures and are fixed to the ground on a concrete slab. Tower cranes provide an ideal combination of height and lifting capacity for tall building construction.
A typical tower crane can reach 70 meters, has a maximum unsupported height of 80 meters, and can lift up to 20 tons, which is why they are widely used in tall-building construction.
Crawler cranes
Crawler cranes, also known as lattice cranes, boom lattice cranes, lattice crawlers, telescopic crawlers, and other names, are the largest mobile cranes. These are heavy-duty cranes that move around a construction site on "tank-like" treads and can lift more than 2500 tons.
All-Terrain Cranes
An all-terrain crane is a type of mobile truck crane that can travel on both the road (at highway speeds) and most off-road surfaces. These cranes, like large trucks, have anywhere from 4 to 18 tires, depending on the size of the crane.
Truck cranes
Truck crane, boom truck, and truck mounted crane (TMC) are all terms that are used interchangeably. Truck cranes are a type of mobile crane that consists of a boom mounted to a truck bed and is thus road legal. Truck cranes are less versatile, smaller, and used to lift lighter loads (load capacity limit of about 45 tons).
