As one variation kind of the bridge crane, gantry crane is mainly used for these operations including freight yard, expected freight goods and bulk cargo handing. Gantry crane has the advantages of high site utilization rate, wide operating range, wide adaptability and versatility.
Because of the overall structure of the gantry cranes like a door-shaped frame, the lower end of the load-bearing girder is equipped with two legs so that the crane can walk directly on the ground track, and both ends of the girder can have outrigger cantilevers. In addition, according to the division of different types, our products will be based on the needs of various venues to make these products that customers want, including indoor and outdoor, electrical and hydraulic, large and small, single girder and double girder gantry cranes, etc.
Our company always has a variety of advanced machinery and equipment, with all kinds of testings to physical, electrical appliances, hydraulic equipment and chemistry. After many times of research and development, our group has established a perfect quality assurance system currently.
Our company introduced and established an internationalized advanced management model, to create a world-class cranes machinery manufacturing enterprises that has a sound sales network and strong technical development efforts.
Types of Gantry Crane
In order to meet the needs of different markets as well as a variety of purposes, our company upholds the core values of customer service. We not only provide customers with professional, efficient and high quality service, and establish stable and win-win cooperation relationship with customers, but also develop high-quality products for multiple uses.
With the development of the society and science and technology, the development of the gantry crane is also a derivative of society and plays a significant role in vigorously strengthening the construction of the country, the service of the people and the output of products. Then, gantry cranes have four distribution methods with the door frame structure, the main beam form, the main beam structure and the use of forms of classification.
According to the door frame form, it is divided into gantry crane without overhang and cantilever gantry crane.
Gantry crane without overhang:
- For full gantry crane, the main beam is without overhang, and the trolley can move in the main span.
- For semi-gantry crane, according to the civil construction site requirements, support legs have different levels of height.
Cantilever gantry crane:
- For cantilever gantry crane, it is the most common form of structure, and the structure of the force and the effective use of space are reasonable.
- For single cantilever gantry crane, this structure is often selected due to site restrictions.
According to the main beam form, there are single main beam and double girder.
- Single girder gantry crane has the advantages of simple structure, convenient manufacture and installation, and small quality. Compared with the double girder gantry crane, the single form cost is quite reasonable. This form of operation is more practical and flexible, and the conversion effect of the site is fast.
2. Double girder gantry crane carrying capacity, the span can be very large. The overall stability is good. Compared with single girder gantry crane, the overall rigidity of the double form is stronger.
How to Choose Gantry Crane
Under normal circumstances, if your request that is under the weight of 50t and the span is less than 35m, without special requirements, you should use a single main beam. If you require a wide leg, and working speed is high, or lifting heavy loads, you should choose double-girder gantry crane.
In addition, If you have special requirements, our group will design a stable and convenient product that you want. Our technicians will use advanced technology that reflect the style of the product, then can be modified accordingly.
The gantry crane span is an important factor affecting the quality of the crane itself. Therefore, in terms of the choice to meet the conditions of use of equipment and meet the span of the series of standards, our design can be to minimize the span under the premise. Besides, our products can meet the stability requirements of the gantry along the crane track direction and the dimensions of the goods will be set according to the corresponding code.
In the process of work, there is a certain space between the goods transported and the passage of the transportation vehicles to facilitate loading and unloading of the staff.
Maintenance of Gantry Cranes
Improving machinery and equipment management system is to ensure that the gantry cranes are scientific and reasonable. Maintenance and repair of machinery and equipment sustainability are the key to improve the safety of machinery.
Although our product quality is trustworthy, we must pay full attention to the maintenance and repair work of the machinery in order to maintain the good condition of the equipment for a long period of time so as to achieve periodic and preventive maintenance. Of course, our professional team will explain the after-sales service of the product accordingly. If the product manifests the corresponding problems, we will assume the corresponding responsibility.
Even if the use of the product may not show any quality problems, our technical staff will use the description of the situation to better maintain the long-term effectiveness of development. Our goal is that customers not only satisfy with our products, but also our service. Let us work together to enhance the product’s functionality.
