Our hydraulic cutters are suitable for material with uniaxial compressive strength ranging from 500 to 25,000 pounds per square inch. All of our products can be utilized in a variety of applications from rock excavation, trenching, demolition and concrete, to underwater cutting, tunneling, and scaling.
The mechanism of cutting process of roadheader with cutting head was researched, and the influences of properties of coal and rock on cutting load were deeply analyzed. Aimed at the defects of traditional calculation method of cutting load on fully expressing the complex cutting process of cutting head, the method of finite element simulation was proposed to simulate the dynamic cutting process.
Oct 24, 2015· A road header machine called a boom type road header. Road headers are advanced, self forced and extremely powerful rock cutting machines are designed to excavate roadways, tunnels and compartments continuously without using volatile. Powered electro hydraulically, they produce no fumes and are used extensively in mineral mining, coal mining and underground construction projects, .
The roadheader does require a greater investment than an excavator with a roadheader attachment. The excavator's performance, however, is limited because it is dependent on the hydraulic power capabilities of the excavator. Attachments are extremely flexible in large tunnels for scaling, cutting manholes, corners and excessive grouting.
