An alternative backhoe excavator for Liebherr dredging
What is the most important performance of excavators working in seawater? Of course, it's corrosion resistant and water resistant. The sea is rich in resources, for wealth, exploitation of sea dredging hydrographic, dredging with essential excavator. Liebherr, as the world's leading construction machinery giant, produces backhoe excavators for its wide range of applications and is well known for its excellent performance.
An alternative backhoe excavator for Liebherr dredging
In New York ports, Hamburg, Germany, the Panama Canal, and even China's rivers and coasts, and even Saline Lake, these inaccessible, harsh areas, you can see the busy super large backhoe backhoe excavator.
Since 1954, Liebherr has been designing and manufacturing excavators that can be used in the worst ocean environments. All dredging excavators reflect the long-term accumulation of Liebherr dredging industry construction experience, and obtained the major ship class social certification.
Let's look for dredging excavator and compared to what are different from the ordinary machines.
First of all, the dredging operation conditions of marine ports are poor, and the components of dredging excavators need high sealing performance and seawater corrosion resistance.
Used excavator not only external paint coating need to use special technology to protect and maintain long-term bright colors and dredging, the hydraulic pressure working cylinder and also want to use nickel plating layer thicker, hydraulic seal with high seawater corrosion resistant materials; the equipment on the bolt M14 above all use stainless steel materials. More importantly, the engine water tank radiator, hydraulic oil cooler, etc., also uses a new design, can avoid the corrosion of seawater and salt concentration caused by the reduction of heat dissipation efficiency.
Dredging excavator is almost completely living on the water, so the electrical equipment are equipped with thermal evaporation device to prevent moisture condensation, all electrical wiring and connector has high waterproof level, lighting is the use of professional marine products, improve the reliability and durability of the operation in a high humidity environment.
Secondly, the dredging excavator is installed on the ship, and the elastic base designed and manufactured by Liebherr can not only be easy to install, but also play a certain buffering role when the excavator works, and reduce the impact on excavator and hull class when the operation is done.
The elastic base is mainly composed of a bottom plate, a buffer rubber block and an upper slewing support. When installing, each component can be connected and installed with bolts as quickly as the building blocks, and finally the excavator is lifted to the slewing support, which is very simple.
Compared with the traditional rigid connection or steel cylinder connection, it not only reduces the welding work during installation, but more importantly, the flexible base installation method can reduce the dynamic impact of the excavator to hull class a nearly 50%.
Finally, according to the different water depth, more dredging devices and bucket combinations are needed for dredging operations.
Liebherr has more than 100 tons of dredging excavators, there are five kinds of models can be selected, each model has more than ten kinds of Boom Bucket and bucket combination, the largest mining depth from 10 meters to 24 meters underwater. Moreover, Liebherr also can be widely used for dredging excavator riprap ship and ship handling.
For perennial on land construction machines should be on this hand, believe that dredging excavator is not too familiar with, today small lead parents knowledge. Believe that one day, our country can also produce advanced dredging excavator.
