Lightweight gantry crane is usually designed as semi gantry crane, small gantry crane, single girder gantry crane. This kind of crane has compact structure, easy operation, high efficiency and wide application. It is mainly used for lifting and transporting material in different places, such as workstation, industrial site, railway construction, warehouse, factory.
Our company, a professional crane manufacturer in China, provides types of gantry crane for sale, such as container gantry crane, cantilever gantry crane, rail mounted gantry crane, rubber tyred gantry crane, etc. These gantry cranes can increase working efficiency, save energy and improve working condition.
Besides gantry crane, we also have other devices, such as wall mounted jib crane, electric wire rope hoist, construction winch, marine winch, single/double girder overhead crane, steel structure, electric flat transfer cart. If you need, just send email to email@example.com
Convenience of lightweight gantry crane
Simple structure. The crane is mainly composed of traveling mechanism, lifting mechanism, the crane frame, main girder, end beam. With compact structure, the crane is very easy to check, install and disassemble.
Light weight. Portable weight makes it convenient to transport the crane from one place to another place. Even a small car can carry with the crane. With light dead weight, the crane can move quickly and stably to improve working condition. Light duty gantry crane is great choice for small building.
Affordable price. Compared with large gantry crane, light small crane has lower price. We have our own crane factory and brand-AICRANE. There is no middle factory between customers and us. This can save much extra cost for customers. We can provide customized small gantry cranes, such as 5 ton semi gantry crane, 6 ton mobile gantry crane for sale, 8 ton workshop gantry crane, 10 ton electric hoist gantry crane, 12 ton travelling gantry crane. If you are interested, just send email to firstname.lastname@example.org , we will reply to u asap.
Main girder structure of gantry crane
The truss beam
The truss beam adopts Angle or i-beam welded form. It has advantages as low cost, light weight, good wind resistance. However, due to many welding points and the defects of the truss itself, the truss beam also has such disadvantages as large deflection, small stiffness and relatively low reliability, requiring frequent detection of welding points. It is suitable for the site with low safety requirement and small lifting weight.
Steel plate welded into a box structure, box girder has features as high safety, stiffness and other characteristics. It is generally used for large tonnage and large tonnage gantry crane. Box girder also has a high cost, heavy dead weight, poor wind resistance and other shortcomings.
It generally refers to the “isosceles triangle honeycomb beam”, the end of the main beam for the triangle, on both sides of the oblique abdomen honeycomb hole, the upper and lower part of the chord. Honeycomb beam absorbs the characteristics of truss beam and box beam, and has higher rigidity, smaller deflection and higher reliability than truss beam. However, due to the use of steel plate welding, deadweight and cost is slightly higher than the truss beam. It is suitable for frequent use or heavy lifting field or beam field. Since this type of beam is patented, there are few manufacturers.
Operation tips of industrial gantry crane
(1) Command signal unknown or disorderly command not hanging;
(2) Over the rated lifting weight without lifting;
(3) The use of the spreader is not reasonable or objects hanging fast not hanging;
(4) Hanging objects or other floating objects do not hang;
(5) Holding brake or other brake safety device failure not hanging;
(6) Crane hanging heavy objects directly processing without lifting;
(7) Slanting pull not hanging;
(8) With the explosive object is not hanging;
(9) Pet-fly was buried in the ground and was not lifted;
(10) With edges and corners piece, not pad not hanging.
