Noise Treatment of Double Girder Gantry Crane

The double-beam gantry crane is an important equipment for manufacturing equipment work, and most companies cannot do without it. The noise generated during use also brings work health problems to workers in the workplace. Operators of double girder gantry cranes encounter noise most of the day. In addition, auxiliary workers around the double-beam gantry crane and repair technicians entering and leaving the machine room will also be affected. So how to reduce the noise of double girder gantry crane?

Let's take a look at the primary noise source of double-beam gantry cranes: in terms of noise emissions, the sound sources of double-beam gantry cranes include electric drive systems, motors, mechanical equipment and gears. The power supply unit also announces noise. In addition, the load-bearing steel structure of the equipment is prone to generate louder noise.

In view of the above noise reasons, the structure of the double-beam gantry crane can be analyzed in depth, and materials can be added in areas prone to radiated noise. For some very simple steel plate structures, such as double-beam gantry crane walkways, the manufacturing and equipment methods should also be strictly carried out in accordance with the process requirements to prevent the same radiation noise as large components. In the key parts of the double-beam gantry crane, stiffeners can be selected to suppress vibration, and sound insulation panels are installed at the key parts. Special joints can also be used to prevent the transmission of structural noise from one part to another. However, the first method is to reduce noise directly from the source, that is, to choose quieter components. For example, high-quality three-in-one motor drive is used to reduce the transmission components; the double-beam gantry crane uses a frequency conversion speed control system to minimize the influence of lifting and work.
