In addition, single girder and double girder gantry crane also have lots of difference. Single beam crane system has only one beam while double beam crane has two beams. Double girder gantry crane usually has stronger loading capacity than single girder crane. The prices of them are different, the cost of single girder crane is usually lower than double girder crane for sale. The span is an important factor to affect the cost of a crane. Double girder gantry crane with cantilever always has two cantilever, which will spend more costs of metal materials.
If you want to know more about our various gantry crane for sale, welcome to contact us. Before purchasing a gantry crane, the customers should determine what types of the gantry crane they need.

Comparison Of Cantilever Crane & Gantry Crane Without Cantilever
Compared with the gantry crane without cantilever, the cantilever gantry can broaden the length of the span so that the crane can handle materials more expediently. The special crane will have higher protection level to the supporting legs so that the supporting legs can be prevented from deformation while the operator lift loads through the border of the main beam.
Generally, cantilever gantry cranes for sale are equipped with saddle to make sure the stability of the crane because its broaden operation range. Our group provides various gantry cranes, if you want to know more about us, please contact us.
Cantilever Gantry Crane Design Standards
In order to broaden the lifting range of the crane, the main girder can expand beyond the supporting legs. The gantry crane is designed to lift heavier materials, and we have different kinds of gantry crane with cantilever for sale, including truss gantry crane and light duty gantry crane. In addition, we also have double girder cantilever and single girder cantilever crane for sale.
The cantilever gantry crane design should consider the need to compensate for deformations caused by changes in temperature and for skew of the span in relation to the supports during movements.
Our customers can choose one depending on their business requirements. These cranes have high performance and long service life, it is ideal for you to use the crane to lift heavy loads. Our company produces the crane in line with national crane design specifications and related standards.
Structure Of The Cantilever Crane
Cantilever gantry crane system mainly consists of metal structure, lifting mechanism, trolley travelling mechanism, the crane travelling mechanism. Mental structure of the crane is a little bit different from the mental structure of full gantry crane, because the crane has one or two cantilevers. Lifting mechanism include motor, hook, reducer, brake, drum, etc. The electric motor drives the drum rotate through reducer, so that the wire rope on the drum can twine to lift the material up and down.
What Are The Main Specifications Of The Gantry Crane?
Lifting capacity. The weight of the materials that can be lifted, together with the mass of the separable lifting devices (grab, electromagnetic chuck, equalizing beam,etc)
Span. Horizontal distance between the center lines of the wheels at both ends of main girder( the distance between runway rails ), which is determined in accordance with the use conditions and process needs. Cantilever gantry crane has broaden length of the main beam so that the special gantry crane has larger span.
Lifting height. Refers to the vertical distance from the center of the hook to the ground. Lifting height depends on the type of lifting loads and type of spreader used. For example, for grab bucket gantry cranes or gantry cranes used for loading and unloading wood, the lifting height is required to be larger.
Duty. Taking into account the extent of the use of weight and time and the number of working cycles of lifting mechanical characteristics. The duty of the crane is determined by the lifting mechanism.
Working speed. Including lifting speed, trolley running speed and crane running speed.

We have eight overseas branches, that basically means customers around the world can get superb after-sale services. Our group will provide installation services or guidance services for our customers. The gantry crane is generally installed from bottom to top.
Before using the gantry crane, the brake, hook, wire rope and other components are supposed to be checked. If the inspector find the anomaly, it should be excluded. Operators can only turn on the main power supply when they are sure that no one on the track.
Cantilever gantry crane is usually applied in outdoor conditions like port, railway and other places lifting heavy materials, etc. But the temperature change outdoor is more acute, and there are lots of dust and harmful gases in some tough environments.
When you maintain the gantry crane, special attention should be paid to the inspection of the motor, to prevent water or oil from entering the motor when the motor works. At the same time you should make sure that the connecting holes and junction box of the motor is waterproof well. When the seasons change, you should replace the lubricating oil of the reducer.
