GB crane rails have several specifications, including QU70, QU80, QU100, and QU120. So how can I choose the appropriate crane specification according to my actual situation? Compared with these crane specifications, what are the advantages of QU70?
Cost
Material cost: QU70 uses relatively less steel, and its raw material price is relatively low in the market. Taking the common U71Mn and U75V materials as an example, the material procurement cost of QU70 is much lower than that of QU80, QU100, and QU120 for the same length and number of tracks. For example, when a large factory needs to lay 100 meters of crane rails, the material cost of QU70 rails may save about 20% - 30% compared to QU100 rails.
Transportation cost: Due to the light weight of QU70, its transportation cost is relatively low during transportation, whether it is transported by road or rail. This advantage is more obvious for long-distance transportation. For example, if the distance from the manufacturer to the site of use is 500 kilometers, the cost of transporting QU70 tracks may be 15% - 20% less than that of QU120 tracks, because the transport vehicle or train car can carry more QU70 tracks, thus reducing the number of transport trips.
Installation cost: QU70 tracks are light in weight, and the lifting equipment required for installation is relatively low. Small cranes or forklifts can be used for installation, reducing the rental cost of large lifting equipment. At the same time, the manpower required during the installation process is relatively small, reducing labor costs. For example, if an installation team installs 10 tracks, installing QU70 tracks may save 1 - 2 working days of labor compared to installing QU100 tracks, and the installation process is safer and faster.
Applicable scenarios
Cranes with moderate lifting capacity: For large cranes with a lifting capacity of about 20 - 50 tons, QU70 tracks can provide sufficient carrying capacity and stability. This type of crane is more common in some medium-sized factories, logistics centers and other places. The QU70 track can not only meet the operation requirements of the crane, but also will not cause waste due to the excessive track specifications. For example, in a medium-sized logistics warehouse, a crane with a lifting capacity of 30 tons is used for cargo loading and unloading. The use of QU70 tracks can ensure the safe operation of the crane and has good economy.
Places with low frequency of use: In some places where cranes are not used frequently, such as maintenance workshops for some special equipment, large cranes are occasionally needed for equipment maintenance and lifting. The QU70 track can meet this intermittent use demand. Compared with large tracks such as QU100 and QU120, the QU70 track is more cost-effective in this case. It can reduce the initial construction cost and long-term maintenance cost while meeting the use requirements.
Areas with limited site space: In some places with limited site space, such as the renovation areas of some old factories, large crane track foundations cannot be installed due to space limitations. Due to its relatively small size, the QU70 track has relatively low requirements for the foundation and can be installed and used in a limited space. For example, in the workshop of an old factory, the QU120 track cannot be installed due to the ground bearing capacity and space limitations. However, the QU70 track can meet the operation requirements of the crane in this area through reasonable foundation design and installation methods.
