20 Ton Double Girder Crane

European 20 Ton Double Girder Crane

European 20 Ton Double Girder Crane Advantages:

（1）Light self-weight

Design software developed by the company combine with three-dimensional modering and finite-element analysis, apply the reasonable structure to lifting mechanism, steel construction and accessories, together with wide use of high-strength material, it increases load capacity, decreases self-weight and has lower weight and wheel pressure than that of traditional crane.

（2）Small space use
Limit distance from hook to boat sides is short but has large working arrange. with lower height above the rail, it makes full use of space of factory building,
（3）Low cost of running and maintaining
As with low wheel pressure and small dimension, it reduces investment of previous construction including factory building, and also reduces illumination and heating expense. The reilable performance and durability also minimizes the additional charges for the use of product at the later stage. Selected components with high quality and preformance lower the maintenance and repair. The total power consumption is reduced, which achieves cost savings.
（4）High performance
Use variable-frequency technology, run with heavy load at low and light load at high speed. The adjustable speed ranges in 1:10, which ensures crane run steadily and reduces impact on factory building. Combination of swing-proof technology achieves a high accuracy position of lifting items.
