Container gantry crane is a large and heavy duty gantry crane. It is widely used for lifting and transporting material at port. It has powerful loading capacity, high safety, compact structure and stable performance. This kind of crane is great choice for port use. It mainly includes two types, rail type and rubber tyred type.
Our company, a professional crane supplier in China, provides types of gantry cranes for sale, such as rail mounted gantry crane, rubber tyred gantry crane, semi girder gantry crane, single girder gantry crane, double girder gantry crane, indoor gantry crane, outdoor gantry crane. These cranes are designed ad produced according to national standards and practical conditions.
Except for gantry cranes, we also provide other industrial devices, such as overhead crane, jib crane, marine winches, construction winch, electric hoist, boat travel lift, stereo garage. If you are interested, just send email to email@example.com .
The benefits of rail container gantry crane
In order to improve the working efficiency of the yard, the rail-type container gantry crane tends to be large and automated, and the development of the container bridge crane on the elevated structure consisting of reinforced concrete column and rail beam high-speed walking on the track.
Rail-type container gantry cranes have been put into operation in major container hub ports in the world. In addition to adding rails in container yards, rail-type container gantry cranes are superior to tyred container gantry cranes in terms of height, positioning accuracy control, anti-rolling performance and stress state of steel structure.
Due to the use of track type, can be increased by the number of wheels to bear more load. Therefore, the span of rail container gantry crane increases. Stable power output due to power supply cable; With the use of electronic anti-rolling system, some foreign large professional companies are developing the automatic unmanned container anti-rolling positioning system with positioning feedback device to improve the operating efficiency.
Operation of container gantry crane
The rail-type container gantry crane is operated by the driver on the bridge platform. The cab is usually suspended under the car and runs with the car.
Bridge linkage platform can achieve all the crane operation. The crane can also be operated on the operation side of the truck to facilitate the temporary shift of the crane. When operating at the running side of the trolley, the electrical interlock is realized with the main operation linkage platform.
The driving control of rail container gantry crane can be adopted in different ways according to the needs of users. (2) ac stator voltage regulating speed regulating system; (3) thyristor dc constant-rate speed regulation system and ac frequency control system, and according to different institutions can be used in different electric drive control system .
What is rubber tyred container gantry crane?
Rubber container gantry crane (commonly known as yard bridge), is a large specialized container yard dedicated machinery, loading and unloading standard containers. It is not only suitable for the storage yard of container terminal, but also for the special container yard.
The crane spreader adopts fixed guide plate. In order to reduce the swing of the spreader, a mechanical anti-rolling device is installed. For the convenience of box matching, the small Angle rotary device of spreader is installed. To change the site operation, 00 ~ 900 right Angle steering mechanism is set.
The cart walking mechanism can be four-wheel or two-wheel drive. In order to prevent the collision between rubber tyred cranes, the crane and the container, the manual deviation correction system and the truck four-angle collision prevention device are provided.
Trolley running machine can use rack type or double shaft, single shaft drive, running smoothly. Under the trolley frame, there is a cab, in which the driver operates the whole crane. The crane adopts ac or dc speed regulation system. It has good speed regulation and constant power control, can automatically adjust the rise and fall speed according to the weight of the box.
