honeycomb girder gantry crane

Nowadays gantry crane is widely used to carry, hoist or load kinds of blocks in different field. According to the different type of girder of gantry cranes, there are three types in mainland of China.

Firstly, it is the box-girder gantry crane. Maybe it is the safest, but too expensive and budget is often taken into account by buyers, so small tonnage cranes don’t use the type. When a project need a large tonnage crane, for example the lifting capacity is 450 ton, its main beam must adopt this type, because it can avoid the accident. But the wind area is too large and self weight is quite heavy.

Secondly, it is the honeycomb girder gantry crane of Zhengzhou Huazhong Construction Machinery Co., Ltd..It is the patented product of Huazhong. Its designers use the structure of honeycomb which is consisted of isoscelestriangle. So its self weight falls in between box-girder gantry crane and lattice girder gantry crane. And it also has many advantages such as high rigid and low deflection and so on... the honeycomb frame crane has the unique pin connection which is not only solid and reliable but also time-saving installation. The flexible legs can transfer to another site conveniently. And the transducer can be installed on the base of users’ required. It is extremely adaptable and widely used in highway, port and railway construction.

 

Thirdly, it is the truss girder gantry crane. It is very prevalent in China. Because it’s main girder uses seamless steel tube, so its self weight is light, and the wind area is too small. But the hidden troubles are obvious. If the main beam lacks one steel tube, the total portal crane will lost stability. Generally, it must be checked every year, and the process is quite complex and users need to pay a lot of money. So many people start to take honeycomb girder gantry crane into account.

With the development of society, gantry crane play a very important role in the constructing of our world. Many projects need to buy gantry crane, if I were you, I would choose the honeycomb girder gantry crane.
