Familiarity with Different Kinds of Crane


Cranes are divided into several groups including single girder overhead crane, double girder overhead crane, suspension overhead crane, single girder or double girder gantry or half gantry crane, wall mounted crane, travelling and column-mounted crane. Here is a summary of different kinds of cranes and it is hoped that the following information helps dear customers choose needed kind of crane.

1. Single Girder Overhead Crane

Single girder overhead crane constructed in Steel Eagle Factory is an efficient and effective equipment to displace materials up to 16 ton. This kind of crane with 39 m opening is even applicable in salons with short ceiling height. It is possible to use available height perfectly and economizing in the cost of constructing a new building with the least safe distance between crane upper flange and the ceiling of factory and crane beams compact dimensions.

Steel eagle Co single girder overhead range consists of different kinds of lateral connections versions for compatibility and adaptability with space and dimensions. These sections compact design allows user to use the highest location of hook.

2. Double Girder Overhead Crane

Double girder crane is stronger! If you need to displace heavy loads up to 120 ton throughout a wide region, double girder overhead crane constructed in Steel Eagle Factory is your best choice.

Double girder gantry cranes are usually used to carry heavy loads in open space. Steel Eagle Engineering Co has designed and produced many gantry cranes such as cabined, equipped with auxiliary hoist, equipped with turn hoist and…

1.1.2. Half Gantry Crane

1.1.2.1. Single Girder Half Gantry Advantages and Applications

Single girder gantry cranes by Steel Eagle Co is an efficient and effective equipment to displace materials to 16 tons. This type of girder can be used up to 39 m opening in open and closed space. Half gantry cranes are constructed as upside-down L that one side of it is installed on ceiling beams and another side on rail which moves on the ground. These cranes are used when it is needed to cover a part of salon. Unlike single girder overhead cranes, single girder gantry cranes have column (base) and usually move on a path which is on floor surface, consequently it economizes the cost of constructing a building. This type of crane is the best solution for displacement in open space.

1.1.2.2. Double Girder Half Gantry Advantages and Applications

Double girder crane is stronger! If you need to displace heavy loads up to 120 ton throughout a wide region, double girder gantry crane constructed in Steel Eagle Factory is your best choice. Double girder gantry cranes of Steel eagle Co guarantees heavy and permanent performance, flexibility and usability. In order to achieve high performance, low weight and advantages like increasing resistance and reducing costs, all sections used for main beams (cranes girders) and heads are optimized by computer. Steel eagle double girder half gantry cranes are constructed with 40 m opening and it is possible to construct them with unlimited capacity and opening in Steel Eagle Engineering Co and they are flexible in specific conditions and needs. For example, faster longitudinal velocity, repairing and maintaining platforms, trolley and hoist units with auxiliary corridors and hoists are all among the features that may be applicable.

5.5.6. Arm Wall-Mounted Cranes

Will a crane with 180° rotation fulfill your needs? Arm wall mounted cranes is your solution. We can install a similar crane on a column in your factory building. It is obvious that this column must have appropriate dimensions. If it is needed, Steel Eagle Engineering Team will specify forces which are applied on that column.

Wall mounted cranes are mainly used for downloading and uploading machines.

5.5.7. Arm Column-Mounted Cranes

Is your factory devoid of an appropriate wall or column to assemble crane? Do you need 270° or 360° rotation range? Column-mounted cranes are the best solution. Steel Eagle Co can offer crane with related column. The crane can be installed on an anchorage inside a hole existing in foundation and or on a flange installed on concrete floor of your factory (concrete floor thickness must be at least 20 cm). All movements can be done manually or electrically, moreover if your column-mounted cranes are galvanized, they can be used in open space.

5.5.8. Travelling Arm Wall-Mounted Cranes

Although arm cranes are ideal solution for limited displacement, you may cover a very larger range with wall-mounted cranes. Travelling arm wall-mounted crane is a travelling wall-mounted crane which does not need angular movement (rotating around one’s axis), so working range increases to full length of your salon. Travelling arm wall-mounted crane is very user-friendly solution along one side of salon, while overhead cranes may be used in higher level without any disturbances.

If you are going to use arm wall-mounted crane, consider it during designing your building. If you need, Steel Eagle Co will offer information related to applicable force eagerly.
