Hangzhong: China's first 6 cubic meter marine grab excavator to ship

The first domestic 6 cubic meter marine grab excavator independently developed by Hangzhou Hang Heavy Construction Machinery Co., Ltd. has completed the loading and recently started dredging operations in Sanya, Hainan.
According to Zeng Jun, Marketing Director of Hangzhong Heavy Machinery, the 6-m3 marine grab excavator independently developed by the company has two national patents for frequency control and storage of electric energy, which fills the gap in the development of domestic large-scale marine grab excavators. The marine grab excavator is 11.4 meters long, 6 meters wide and 9.2 meters high. The whole machine weighs 148 tons. The grab capacity is 6 cubic meters and the rated lifting power is 25 tons. It is characterized by energy saving and low carbon, and can The consumption is only 80% of that of conventional DC speed-regulating systems for marine grab grabs. Compared with marine grab grabs using diesel fuel, it has advantages such as low noise and zero pollution. The overall control system of the excavator is safe, stable, reliable, and has low requirements on the environment of the power grid. It can realize heavy-load and low-speed startup and can flexibly adjust the speed. The safety protection function is complete. In addition to devices that protect itself from overvoltage, undervoltage, overload, overheating, short circuit, etc., it also has a peripheral protection chain protection mechanism. The excavator has high working efficiency. The traditional marine grab excavator has a lifting speed of 56 meters per minute. The lifting speed of the model can reach 72.4 meters per minute.
The marine grab excavators are mainly installed on dredgers and are suitable for excavating mud, sand, cobbles and broken rock after blasting. They are currently used in port construction, channel dredging and maintenance in offshore and inland rivers, and underwater excavation in marine engineering. Waiting for work. There are many ports in China, and the inland waterway is long. There is a great demand for bucket bucket excavators with large bucket capacity. Grab bucket excavators with large bucket capacity on the domestic market are basically foreign equipment. In order to further develop the market, Hangzhong Machinery also installed a set of energy-saving devices for the 6-m3 marine grab excavator, which further achieved the goal of saving energy by 30%. At the same time, the company is also actively researching and developing 8 cubic meters marine grab excavators with larger grab capacity.
