The Single Girder Gantry Crane is mainly used outdoor working site for hoisting and moving of materials. It has the advantages of simple structure, convenient transportation and installation, light self-weight, and the main girder is mostly a derailed box-shaped frame structure. Single girder Gantry Crane is usually used for lifting weight ≤ 50 t and the span ≤ 35 m.
Single girder gantry crane legs can be L- and C-type. The L-type single girder gantry crane is easy to install, stable structure, light slef-weight. However, the space for lifting cargo through the legs is relatively small. The C-shaped legs are made of a slanted or curved shape with the purpose of having a large lateral space for the goods to pass through the legs.
Weihua also provide European standard (FEM and DIN standard) single girder gantry crane which has the advantages of compact structure design, light self-weight, smooth running, world class brands components and electrics, less noise, less consumption, large working space, precise positioning, etc. The Electric Hoist is also FEM and DIN standard.

Internet of things meter has become a "rescue" to ease the world's water crisis
[China Instrument Network Instrumentation Industry] Pairing and detecting leaks of sensors and meters is an effective means to reduce consumption. At present, more than 55% of the world’s population live in cities or cluster around cities, indicating that the urban population accounts for the majority. This is the first time in human history that the urban population is larger than the rural population.
According to the 2015 WHO/UNICEF joint monitoring report, the world’s water scarcity problem is getting worse. One third of the world’s population do not have access to adequate sanitation resources. One's population did not have enough safe drinking water resources. Of course, the report also confirmed that the water crisis has improved in some areas, but there are still many potential dangers.
The report highlighted the significant improvement in the rural water supply situation, but the process of improving safe drinking water has been slow. At present, more than 55% of the world’s population live in cities or cluster around cities, indicating that the urban population accounts for the majority. This is the first time in human history that the urban population is larger than the rural population. According to a recent research report from WaterAid, the urban population continues to rise and is expected to reach two-thirds of the world's population by 2050. This undoubtedly exacerbates the pressure on safe drinking water supply.
We live in an era of uncertain weather. The effects of global warming caused by a steady increase in temperature have already had the same impact on the Earth as natural disasters such as droughts, storms, and floods, which in turn have a serious impact on water supply and, over time, the problem remains. Left over, unable to solve. It is one of the biggest challenges for the water company to replace the water pipe before it expires or wait until the water pipe is damaged and then replace it and damage it. For example, in the United States, there was a water pipe burst in Philadelphia. Nearly 40 million liters of water rushed out and flooded the streets of Philadelphia. The reason was that the burst water pipe was an old iron pipe installed in 1885.
So how can we ease the world's water crisis? Interestingly, the answer lies in another traditional infrastructure: mobile networks. In an era of unprecedented technological advancement, this technology may have already reached people's realization, but low-power wide-area (LPWA) network technology has developed steadily and is poised for development.
What is unique about this technology? It can support online information exchange and the battery can be used for a long time. In the utility sector, especially in water resources management, sensors and water meters can be used to detect leakage and reduce consumption.
The recently released "GSMA Smart City Guide: Water Resources Management" explains how this technology, along with other existing mobile communication technologies, becomes an integral part of the smart city and details the introduction in Las Vegas. A study of typical cases in Atlanta and Tainan, Taiwan. These case studies show that the application of mobile technology may bring about a reduction in consumption, greatly improve detection leakage and better monitor water quality.
Of course LPWA will depend on its cost-effectiveness, and in this regard, there are many ways in which LPWA has advantages over traditional solutions. Because the LPWA device sends a relatively small amount of data, the total cost of the solution is kept to a minimum, which means that the technology can be retrofitted at a lower cost.
Importantly, LPWA gives water companies the ability to remotely monitor water usage at many locations below ground, which means that they can take readings more often and will become less manual or drive dependent on readings. Existing remote monitoring solutions that support mobile devices, such as AT&T's HydroPoint, have saved customers by $137 million and proved their value only in mid-2015.
