QU crane rails are special rails designed to withstand the huge wheel pressure and complex stress during crane operation, and are widely used in various heavy lifting operations. According to their specific parameters and performance differences, they can be divided into the following common models:
QU70: rail height 120mm, bottom width 120mm, head width 70mm, waist thickness 28mm, theoretical weight per meter is about 52.77kg. Due to its relatively moderate carrying capacity, it is suitable for medium-sized gantry cranes or bridge cranes with a lifting capacity of about 20-50 tons in general industrial plants. The operating intensity and the weight of the heavy objects lifted in these places are not at the top level. QU70 can meet the needs and is cost-effective.
QU80: rail height 130mm, bottom width 130mm, head width 80mm, waist thickness 32mm, theoretical weight per meter is about 63.69kg. Its various dimensional parameters have been improved, and its carrying capacity has been further enhanced. It is suitable for cranes that lift heavy goods such as containers in ports and logistics centers, with a lifting capacity of approximately 50-100 tons, and can stably support frequent crane operations.
QU100: Track height 150mm, bottom width 150mm, head width 100mm, waist thickness 38mm, theoretical weight per meter is about 89.05kg. This type of track has better bending strength and fatigue resistance, and is suitable for large shipyards, steel mills, etc., with a lifting capacity of 100-200 tons or even higher super-heavy cranes. The cargo such as ship parts and large steel products lifted in these places is extremely heavy, and QU100 can ensure the smooth operation of the crane.
QU120: Track height 170mm, bottom width 170mm, head width 120mm, waist thickness 44mm, theoretical weight per meter is about 118.10kg. As the largest model in the QU series, it has super strong load-bearing capacity and stability. It is often used in large-scale water conservancy project construction sites to lift large gates, mechanical equipment and other super-large heavy objects, and the lifting weight often exceeds 200 tons.
Different models of QU crane tracks, with their own unique specifications and parameters, are suitable for cranes of different operating intensities and lifting weights, and play a key role in various industrial scenarios. When actually selecting, it is necessary to comprehensively consider factors such as crane type, lifting weight, frequency of operation, and budget, and make a reasonable choice to ensure that the track and crane are perfectly matched to ensure safe and efficient operation.
