Specifications of gantry crane
The gantry crane has significant characteristics due to the structure for which it is intended, which has made it find a special place in various industries. Among the features of this crane are:
- Ability to run in both single-bridge and double-bridge modes
- Suitable for outdoor
- Using a gantry crane as a column and single bridge
- High speed in loading and unloading operations in industrial environments
- Ability to install the necessary equipment on this crane
- Installing the operator on the crane for better guidance
- Access to all facilities and equipment using the maintenance corridor in the double bridge gantry crane
Types of gantry cranes
The gantry crane is designed and built in different types according to the types of use. The design of the gantry crane is done in two types: simple and cantilever, and these two types are also made in single-bridge and double-bridge categories, each of which has different load capacities. This diversity in the construction of gantry cranes has caused it to find wide application and be made and used according to various situations. A simple gantry crane is like an overhead crane, which has two columns on the sides, and the carriage moves transversely between the two columns. The cantilever gantry crane is built beyond one or two sides of the columns on which it is placed, and it is very suitable for conditions that require more lateral movement to carry the load. The application of the cantilever gantry crane is more It is for loading in the field of shipping industry and ports.
Single bridge gantry crane
The single-bridge type of gantry crane is used to move objects or loads weighing up to 10 tons with a span of less than 20 meters. The most common use of the single-bridge type of this crane It is used in the construction industry and construction projects, which has caused a lot of cost savings.
Pair gantry crane
As its name suggests, this crane has two bridges and increases the speed of movement due to this feature. A cabin is also considered for this type of crane. Gantry crane with unlimited tonnage and high coverage is very efficient in moving in different places. The use of this crane in various industries and in open and closed spaces is very wide. This crane is made in two types, simple and cantilever, so that they can be used as much as possible according to the conditions.
Advantages of gantry crane
Using a gantry crane in different industries is very useful and efficient in order to speed up the implementation of different projects So it can be said that despite these structures, many problems exist in businesses regarding Moving and transferring heavy objects and loads is easily solved. A gantry crane is one of these very necessary and important structures that, with its proper performance, has been able to develop and advance civil and industrial activities. The gantry crane has significant advantages, including the advantages of using this crane:
- moving objects in three different directions: length, width and height
- Possibility of using a gantry crane in places where it is not possible to install a ceiling crane
- It has a motion limiting system, safety sensor and moving lift, repair corridor, load weight indicator and access ladder.
- Moving objects and supplies in industrial areas such as halls using this crane is very affordable
- Low costs for maintenance and service
- Ability to supply electricity through a cable roll installed on the crane legs.
- Equipped with a rail clip to protect the crane in adverse weather conditions as well as to close it
Application of gantry crane
The main application of gantry crane is for places such as sheds, large industrial halls, large industrial workshops, open warehouses and ports. Mobile gantry cranes can be very compatible with the environment and conditions in which they are placed. The dimensions and size of these cranes can be adjusted to any desired scale. A gantry crane can be used instead of a roof crane in any roofed place. This crane can be used to move and transport dangerous materials. . The components of a gantry crane consist of a brake, carriage or moving carriage, bumper and bridge, each of which must be inspected and checked at a certain time and periodically.
Production of gantry cranes
This structure, due to its important task, must be designed and built very precisely and engineered so that the smallest error and problem does not occur. The construction process of this crane according to the design that It is considered to have very important points that can create a reliable and resistant structure. More attention should be paid to connections in two types of single bridge and pair of bridges. Considering the distance of bridges from each other with high accuracy. The distance between the wheels and the length of the wheel are of great importance, so they should be treated with great care. Column control against tension and the possibility of bouncing. It is very important to consider the angle between the columns in the crane, so you must be very careful in this regard. A safe and accessible path to the motor equipment during repair and inspection should be placed, which also has the necessary standards. If the gantry crane is installed and used in an outdoor space, all adverse weather conditions should be taken into account, because in these conditions there is a possibility of the crane overturning, because the strong wind affects the longitudinal and transverse movements of the crane. It is also very important to protect the crane's motor system and equipment against strong sunlight.
