What is an A-frame crane? A-frame cranes usually refers to A frame gantry cranes which is a special variation of regular gantry cranes, with A shape like side profile. With various crane specifications and crane configuration, our A frame gantry cranes can be used for light, medium and heavy duty material handling, which includes the following:

• 5ton ~50ton light duty & medium duty single girder A frame gantry crane
• 5ton ~320ton heavy duty double girder A frame gantry cranes,
• 0.5 ton ~10 ton light duty Portable A frame gantry crane.
• Customized pee-engineeredA framegantry cranes are available.

A frame gantry crane is widely used forgeneral material handling indoors and outdoors. Combined with foreign advanced crane technology  and China's traditional crane advantages, , integrated years of experiences on gantry crane designing and manufacturing, our A frame gantry cranes offers excellent solution for small tonnage and large tonnage load handling.  All the designing and production of our A frame cranes are in accordance with GB/T 3811、GB/T 14406、GB 6067.1, and in accordance with related European gantry crane standards and regulations, Leave us a message below to get your particular designed A frame crane now.

With a choice of gantry design or portable gantry design, our A-frame gantry cranes are able to offer light duty and heavy duty material handling solution for indoor and outdoor application with capacity from 0.25 ton to 320 ton.

Portable A frame gantry crane

A frame gantry crane with portable gantry frame design is usually known as a small gantry crane or portable gantry crane,which can be wheeled between locations as required for lighter duty material handling with a wide application.

The small portable A frame gantry cranes can be designed and manufactured with various of specifications and configurations with the capacity range from0.5 ton ~10ton

Features of mini mobile gantry cranes

For heavy materials handing, it is not necessary to install expensive equipment or to change your facility permanently. Portable A frame gantry crane with capacity up to 10 tons can help you do the hoisting work efficiently and economically.

• Portable - No permanent installation required, the light-weight A frame crane can travel around with casters or rollers freely. With portable gantry design, the A frame cranes can be relocated and used in many applications.
• Adjustable - With height adjustable gantry design , the A frame crane can be adjusted quickly to offer the largest flexibility for various loads handling during crane operation.
• Flexible - With portable and adjustable gantry design, the A frame crane is capable of handling loads of different sizes, with adjustable lifting height and span and A frame gantry is able to be assembled and relocated easily and rapidly, ensuring optimal productivity in your plant and facility
• Stable - The A frame crane provides a very stable base with a heavy duty end frame design and square tubing uprights, knee braces and channel base,etc.All nuts, bolts, and pins of A frame gantry are plated with corrosion resistance. And all A frame gantry cranes are designed and manufactured in accordance with the relative national regulations and laws to ensure the high safety and quality of the small A frame gantry.

Fixed A frame gantry crane

Fixed A frame gantry cranes are relatively static gantry crane system swith A-frame gantry designs, which make up the less of mobility with increased strength for heavier capacities from 5 ton ~320 ton. The fixed A frame gantry crane comes in multiple configurations and specifications to provide lifting solution to a number of different projects.

Box girder A frame gantry crane

A frame gantry crane with box girder design - The box shaped gantry girder is welded withsteel plates , with features of high safety, stiffness and other, etc. Box gantry girder design is usually used for gantry cranes with large and super large tonnages. The box gantry girder design also has the drawbacks of high production cost, heavy selfweight and poor wind resistance.

A frame gantry crane of single gantry girder design -The A frame gantry crane with single girder gantry designis for light to medium loads, handling with capacity of .5ton ~50ton. The single girder A frame cranes are for general material handling in indoor and outdoor uses

A frame crane of double girder gantry design -A frame crane with double gantry girder is designed with increased strength and large tonnages for material handling with capacity of 5 ton to 320ton. The double girder Aframe gantry crane offers higher efficiency and lifting speed than that of single girder gantry crane. The single beam A frame gantry crane is aimed at lifting light to medium loads, and it can be employed for both indoor and outdoor uses.

A frame double girder gantry crane is designed with increased strength and large capacity, usually in a range of5 tonto 500 ton. This A-type gantry crane provides higher efficiency and greater lifting speed than the single girder crane.

Truss girder A frame gantry crane

A frame gantry crane with truss girder design - The truss gantry girder is welded with angle steel or I-beam, featured as low manufacturing cost, light self-weight, and good wind resistance. However, due to the large amount of welding points and the inborn defects of the trusses structure,the truss gantry girder has the disadvantages of large deflection, low rigidity, low reliability, and frequent welding spotsdetection

A frame gantry crane design features

• High security, stable performance. Learning from advanced crane tech abroad and from years of experiences in practical gantry crane design and manufacturing, our A frame gantry cranes with strong structure and reliable crane parts and components are inborn with the features of high safety and stable performance.
• Reliable structure, light weight, small loading pressure. By adopting a new gantry frame, the rigidity of our A frame gantry crane is improved. With various technical measures,the weight of the whole gantry crane is reduced by more than 15% and the maximum wheel pressure of A frame gantry crane is reduced by 10% to 20%.
• High precision, beautiful appearance. The complete supporting frame and the reaming holes of the trolley are produced with high precision and accuracy to avoid any deviation during manufacturing and welding to ensure the assembly and installation of A frame gantry crane easy and accurate, and finally offering you A frame gantry with excellent performance and beautiful appearance.
• Accurate operation, High safety. Adopting AC frequency conversion PLC control program, the operation of A frame crane is more simple and accurate and also the A frame gantry crane is with high safety and securityby adopting acomplete set of mechanical and electrical protection devices,including the overload limiter and height limiter of main and auxiliary hook, etc.
