What is the difference between a single-beam crane and a double-beam crane?

What is the difference between a single beam crane and a double beam crane? In fact, single-beam cranes and double-beam cranes, as the name suggests, are that single-beam is relatively simpler in structure than double-beam. Then, what are the differences between the single-beam and double-beam of bridge cranes, and what are the connections? ?

　　 1. Work environment

　　Single-beam cranes are generally used in places with small spans and lighter lifting weights. Often, the working environment of single-beam bridge cranes is relatively small. The double-beam bridge crane has a large span, a heavier lifting capacity, a brighter working place, and a high level of work. Compared with single girder, double girder bridge cranes are more versatile.

　　 2. Structural features

    　Single beam crane is lighter in weight, simple in structure, and easier to install and disassemble. The double-beam bridge crane has complex structure, heavy weight, and relatively complicated installation.

　　 3. Production cost

　　The cost of single-girder cranes is lower, the materials used are less, and the cost is mainly determined by its span. Single-girder bridge cranes have a smaller span, so the price is cheaper. Double girder bridge cranes are expensive to produce, use a lot of materials, time-consuming and labor-intensive, and have a large span, so the price is more expensive.

　　 4. Operation object

　　Single girder cranes are generally operated on the ground, so we only need to operate them through the handle or remote control. Double-beam bridge cranes are generally used to control images: grabs, electromagnets, special fixtures, etc., so operators are required to control the work.

　　 5. Mechanical properties

　　Single beam crane has low stability, slower speed, less load capacity, suitable for short-term use. The double-beam crane has high stability, high speed, high performance level, large load-bearing capacity and long service life.

　　 6. Main beam structure

　　The simple understanding of a single beam crane is that there is only one beam on it, and an electric hoist is installed on the beam as the main lifting mechanism. The double-beam bridge crane is divided into two models: QD and LH. Compared with single beam, QD is two beams. It uses a hoist as the lifting mechanism, and the LH is also a trolley, but it uses an electric hoist as the main lifting mechanism.升 Institutions.
