The double-girder overhead cranes are the best heavy-duty overhead lifting solutions. The dual-girder crane design consists of two parallel girder bridges going through each platform of a double girder overhead arrangement. One bridge connects the two platforms, and the other one attaches to the opposite platform. In the double-girder design, the primary movement is from left to right.
The main advantage of this system is that it gives good leverage. It allows for greater speed compared to a single-girder design and offers better stability. While there are other types of overhead cranes, such as the four-girder and five-girder design, most construction companies would find the dual-girder model (modelo de doble viga) more than adequate.
Multiple girder overhead cranes can be divided into three different categories depending on the weight and the number of pillars in the structure. The single girder system is the most common type of overhead cranes, consisting of two parallel girder structures joined together using four girder beams. The two beams are fixed to the structure by means of the three primary columns. This system has the least number of beams per girder, allowing for light to moderate weight to be supported.
A double girder overhead crane consists of three beams fixed at an angle, and the angle is set by the center beam. Each of the four beams supports a heavier weight than that of the three beams, resulting in greater stability and leverage.
The four-girder design is also known as the “triangle design.” This design requires three beams to support the weight of the structure, allowing the three beams to move vertically through the structure. The triangle design is commonly used in large industrial or commercial buildings and is the only design where the center beam moves vertically.
There is also the five-girder design, which consists of four beams, but only one is fixed in position. The other two beams move vertically, with the middle beam resting on top of the floor joists. Both designs are capable of supporting high loads and provide a high degree of stability and leverage. This design offers the most balance and stability, allowing for greater leverage. These types of crane are used in most residential and commercial buildings.
Even if some models can lift heavier loads than the double-girder overhead crane, you might still be better off choosing this particular model if it perfectly fits your specific lifting requirements. Also, the double-girder overhead crane is often considered the most efficient of all types of overhead lifting solutions. The reason is that it offers adequate lifting capacity while maintaining a relatively low operating cost.
It pays to know that you can add extra features to improve the double-girder overhead crane’s functionality. Some of the most popular additions include walkways, lights, and operator cabs.
