Due to the various kinds of working environments in outdoor or indoor, the gantry cranes we need are various, different with the box structure gantry crane used in regular working environments, the truss gantry crane is suit for the factories, open area between fixed cross, construction and installation sites, lumber yards and other place, because the rigid steel structure and small friction force, the truss type crane is popular for the workers in these place where has big sandstorm to handle or lift weights. With single or double girder, 3.2 ton -200 ton lifting capacity, truss structure crane enjoys great reputation among the world.
All gantry truss crane can be divided into two working-level; they are the mid-level and light-level system according to the time and frequency of use. As the responsible gantry crane manufacturer, guarantee top quality for every our truss beam gantry crane.
1.single girder truss crane for sale, because the difference of goods or materials need to lift, we also need the different lifting capacity’s truss gantry cranes, among these different truss type gantry crane, the single truss crane is mainly designed to lift the goods below 20 ton, with 12-30m span and 6-12m lifting height, the single beam truss structure gantry crane is famous in stone factory or construction sites.
In a word, there are mainly two different truss crane types, the first is the single girder truss structure crane. Besides a little different in the steel structure, which is only the one single, and another is two. The single girder type truss cranes hold quite smaller lifting capacity. Usually is from 2 ton to 50 ton.
However, if there are several requirements about the single girder truss type crane in lifting capacity or the other aspect, we also can offer you the custom service.
Just like the word above, compared with single girder truss crane, on the one hand, the double girder truss cranes enjoy similar bridge structure, however, on another hand, the double girder truss gantry crane reach more lifting capacity, usually over 100 ton or even more, if you have special requirements.
All of our truss type gantry cranes can be designed with A3, A4, A5 work duty; you can choose them freely according to your own needs. Besides the standard technical mentioned above, we also offer the truss girder gantry crane custom service to provide you satisfied truss cranes.
1.Freely choose many truss gantry crane components, such as the rail, remote control, cabin control, different size of common electric hoist or European electric hoist.
2.Both the single girder and double girder truss structure crane can be design in high standard European type gantry crane with less or zero maintenance.
3.Aimed at the important truss crane components, we will storage a certain number for the convenience in buying and maintenance for our customers.
4.A series of safety device to ensure high safety single truss crane, such as the overload protection, emergence power off device, limit switch and anti-sway section for hook and so on.
5.Top quality in truss cranes, every mini componentin truss type gantry crane is made with top class quality and one hundred diligent, such as the forge hook, the magnet, or grab, as well as European type zero maintenance electric hoist.
6.Low price in every our gantry truss cranes, which almost fifth less than the other truss beam cranes.
1.Both the test and assemble of our gantry crane all meet the regulations of GB and T14405-93.
2.There are three different manipulation methods of a truss crane to choose. The ground operation and cable control that includes open and close control. Our customers also can decide whether the control devices are installed in left or right according to physical truth.
3.The main lifting parts are divided into two types, the single hook and double hook.
With stable running and best wind-proof ability, our gantry crane enjoys the highest safe performance.
4.Should any damage or defect found in your gantry crane, you will get immediately change or maintenance from our professional engineers.
5.We always stock some components for our truss crane, which offer drastically facilities for our customers.
6.We are quite confident to provide all test service before you buying.
7.With sales spots nationwide, we can guarantee the fast delivery.

The truss crane also belongs to large-scale equipment, which need high safety and easy operation, as well as installation under the professional guidance. The basic procedure is as follows.
Install the rail
Assemble the crane structure
Choose the lifting equipment according to the part weight
Lifting the support legs
Assemble the main girder in the ground
Lifting the main girder
Install the end crossbeam
Lifting the trolley mechanism
Assembly the other parts
Carry the preliminary test
After assembly, the geometry dimension, perpendicularity, levelness and deflection must be checked in the following ways:
● The wheels span deviation: S＜10mm
● The main girder deflection: AF=（0.9/1000～1.4/1000）
● The diagonal difference of main girder:（D1-D2）≤5mm
● The side curvature of main girder: AFP≤S/1200
● The trolleys’ gauge difference: Both sides: ±2mm Midpoint: S≤19.5mm
● Adjust the wheels (Parallelism, perpendicularity, apposition)
Ensure your truss beam gantry cranes are installation rightly, the geometry dimension, perpendicularity, levelness and deflection must be test according the following methods.
1.The deviation between span: S＜10mm
2.Deflection of main girder: AF=(0.9/1000-1.4/1000)
3.Main girder diagonal difference :（D1-D2）≤5mm
4.The side curvature of main girder: AFP≤S/1200
5.The trolleys’ gauge difference: Both sides: ±2mm Midpoint: S≤19.5mm
6.Adjust the wheels (Parallelism, perpendicularity, apposition)
In many working occasions, we will find the gantry crane. Using this, you will save much cost and get high productivity. Among these many kinds of gantry cranes, such as the AQ-MG type double girder gantry crane, the AQ-BMH type semi gantry crane, the truss structure crane is very famous in poor worksite, especially where has high wind frequently. Thanks to the smaller contact area, leading to the smaller obstruction, which ensure high safety and stability.
If your working place is like this, many be a truss girder gantry crane is your best choice.
Due to various kinds of usage of truss crane, we design many models truss type gantry crane for sale with some optional parts. These accessories mainly contain remote, rail, cantilever, grab for bulk cargo, magnet for steel or the other metal materials and the hook for large weight. Of course, aimed at the other parts about the truss crane, we also store some for the emergence condition and fast delivery. If you have any demand, don’t hesitant, just contact us freely.
Besides, we also offer you a series of free service for truss cranes, such as the free truss crane design, free installation and maintenance guidance, one year free maintenance and lifetime maintenance, and free test service.
With so competitive price and top quality, truss crane made by our company has exported into many countries around the world, such as the England, Africa, Middle East, Austrial and so on. Just send your free inquiry for low price truss structure gantry crane.
