Winch is mainly used for lifting materials in construction, water conservancy, forestry, mining, port, etc. Recently, Summit has successfully developed a new type of suction sand winch, which is biggest in Asia at present.
The engineer Lizhisheng of Summit says this winch is designed by Japanese,the size is 8*8*10m
Li says this project is the biggest among similar type of winch,not only for its volume but also for its technology.
This winch isn't the heaviest though the volume is so large.That means double difficulty in technology,from welding to moulding,then machining,a big challenge in every step.
After two months'fighting, now the winch has approved by Japanese experts,winning high praise from customers,defending the honor of Chinese manufacturing.It's perfectly interpreted the craftsman spiritual power.
