PART 2: COMPANY ADVANTAGES

1, Quality Guarantee.

1) Imported the Main Body Assembly as a whole.

The Main Body Assembly includes Front head, Cylinder and Back head, but nobody in China can supply the Main Body Assembly as a whole. The Hydraulic Breaker manufacturers have to buy the three parts separately and then combine together, which obviously will cause some problems. But Yantai Jiwei imports the Main Body Assembly as a whole from foreign countries for HMB series Hydraulic Breakers, which guarantees the best quality and lest breakdowns.

2) Ideal structure design, wonderful performance.

a, HMB series Hydraulic Breakers adopt simple Hydraulic circuit system, which use oil less and improve efficiency more.

b, The bottom of Hydraulic Breakers adopted high strength and wear resistance steel plate, which makes HMB series Hydraulic Breakers not only enjoy a long life, but also enhances the working efficiency.

c, The advanced crystallization of complete oil pressure and slight oil adjustment was introduced, which guarantees the incredible impact force and durability. And it makes all clients satisfied under any working conditions.

3) Strong compatibility.

Our HMB hydraulic breakers are compatible with all kinds of excavators such as Doosan, Dawoo, Furukawa, Volvo, Hitachi, Kato, Kobelco, Komatsu, Sumitao, Liebheer, Hyundai, Cat, Jonyong, Changjiang, Daemo, Liugong, Yucai, Case, John Deer, Fotonlovol and Loader etc.

2, Competitive Price.

We are just at the stage of building export business networks, thus we can give more support and discount to the foreign clients and distributors. So our price will be much more competitive compared with the similar suppliers.

3, Good Service.

We have one team of engineers standby to solve the problems from foreign countries specially.
