🟡 Single -bridge ceiling 🟡 🟡
Single-bridge overhead cranes are used to move materials in halls with small openings and tonnages of less than 10 tons, which reduces the dead load of the bridge on the columns of the structure and is economically more economical because the total weight It reduces the structure. In single bridge structures, one bridge is placed in line with the opening and two longitudinal guides that move the single bridge structure along the rails on the rails.
To move across the opening to The trolley device located in the elevator, which moves the elevator with the transverse motion motor, and the movement along the hall is the responsibility of the longitudinal guides who move the elevator along the hall with the wheel box and gearbox motor. This is one of the disadvantages of this work class structure. Lower and lower working height compared to two-bridge overhead cranes.
🟡 Crane two bridges 🟡 🟡
Double bridge overhead cranes are the best solution for moving materials in halls that have a span between 10 and 50 meters and a capacity between 1 and 100 tons, and also with this structure you have the best working class and the highest working height. You will receive and also by using engineering calculations and construction of the structure according to the standard and with low dead weight, you can also get the best use from an economic point of view. Also, another advantage of this type of cranes is that with the presence of a selected corridor in the crane body, in addition to ease of access and The possibility of repairing parts of the trolley (trolley) also provides a suitable possibility for repairing and replacing the lamps of the hall, the heating facilities of the hall and the power supply lines.
🟡 Except of the ceiling of the direct pendant and curved 🟡
This type of crane, in cases where you are not able to install columns and beams, by setting up this system, you have the possibility to easily move objects in the hall area, and this system is also used to move materials with an opening between 4 and 10 meters and a capacity between 0.5 and 10 tons has a lot of use, which in this type of structure gives you the possibility of maximum lateral access (more than the opening of the working beam) or the maximum working height. It also has the ability to lift move in any direction. This type of crane is mostly used in the rail industry and it is available in two types of overhead cranes, straight and overhead.
