Heavy duty gantry crane is an efficient material handling solution widely applied in manufacturing industry, construction site, ship building industry, shipyard, port, rail terminals and so on to perform large and heavy lifting tasks. This heavy duty crane can lift up to several hundreds tons and suit various application requirements. A typical design of heavy duty gantry crane falls in double girder so as to undertake heavy loads.
The heavy duty gantry cranes have many different types. According to different running mechanisms, we supply rail mounted gantry crane, rubber tyred gantry crane. With regard to different gantry frames designs, we have A frame gantry crane and U frame gantry crane for your choice. We also provide custom design as per requirement.
Heavy Duty Gantry Crane Types
Our gantry crane is available in several main models to cover a wide range of lifting needs. Before selecting a heavy duty crane for your application, you should have a basic understanding of these different types of gantry cranes.
AQ-MG double girder gantry crane is one of the most commonly used lifting systems for many indoor and open workplaces. It is a typical A-frame gantry crane, mainly composed of main beam, supporting legs, end carriages, hoist trolley, optional saddle, and electrical system. Its capacity can reach 500 tons. This lifting equipment has advantages of high utilization of working site, strong versatility and adaptability.
The main beam is mounted on A-shape gantry frame which is connected to end carriages. Its design is based on the crane working duty and operation frequency. This gantry crane is a rail mounted type as the end carriages travel on rails mounted on the ground. The saddle structure makes the equipment bear a more reasonable force. According to differential environmental conditions, you can choose the most suitable metal structure including box and truss type. In addition, you can determine your heavy duty crane with or without cantilever.
Double girder heavy duty gantry crane parameters:
- Load capacity: 5-500t
- Span: 18-35m
- Lifting height: 6-18m
- Lifting speed: 1.5-11.5m/min
- Trolley running speed: 10-40.1m/min
- Crane running speed: 16-50m/min
- Work duty: A3-A7
Double girder semi gantry crane parameters:
- Load capacity: 5-32t
- Span: 12-30m
- Lifting height: 6-12m
- Lifting speed: 6-11.5m/min
- Trolley running speed: 37-40.1m/min
- Crane running speed: 37.7-40.1m/min
- Work duty: A3-A6
U type gantry crane is another type of heavy duty gantry crane, suitable to handle large sized materials such as containers. Due to the U shape design, there is larger space between two legs in contrast to A type gantry crane. Besides, this gantry lifting equipment does not require any saddle support, therefore the overall height of this gantry crane can be lowered given the same lifting height.
U shape heavy duty gantry crane parameters:
- Load capacity: 10-50t
- Span: 18-35m
- Lifting height: 6-18m
- Lifting speed: 5.9-13.3m/min
- Trolley running speed: 31.3-40.1m/min
- Crane running speed: 40.1-44m/min
- Work duty: A5-A6
Which type of heavy duty gantry crane is suitable for your need is determined by your application requirements. So you should consider a few things such as if you need a more flexible lifting system or not, or what your gantry crane is used for. For different applications, we will provide the most appropriate material handling solution so as to maximize your production.
How to Operate A Gantry Crane
The gantry cranes whether designed in A frame, U frame or mobile type, are normally operated by wireless remote control, cab operation or the combination of the two methods. The specific operating mode is highly dependent on the gantry crane type you choose and its working condition.
The cab operating mode allows operators to sit in the cab to complete their work. Many gantry cranes especially container gantry crane will adopt this operation method. Since the cab is mounted on the gantry crane, the view of operations will be subject to a certain restriction, which is prone to accidents. Therefore, an additional worker from the ground is more often needed to work together with cab operator in order to complete the lifting tasks perfectly. Besides, the cab operator should receive professional training and have qualification to do the job.
The wireless remote control is a popular option for both light duty and heavy duty crane as it only requires the crane operator to complete the operation from the ground. Through remote control, the operator can choose a better and more secure position to operate the equipment without operator’s view being blocked. It features low cost, durable performance and minimal maintenance. In addition, without the need of an additional co-worker during gantry crane operation, the remote control can greatly improve the working efficiency.
How Much Does A Heavy Duty Gantry Crane Cost
For different applications, you can adopt various types of gantry cranes to carry out lifting tasks, and the price of each gantry crane differs from each other. The key to buy a heavy duty gantry crane is to choose a cost-efficient one so as to create maximum value for your business.
