KAMY offers unmatched quality, value, and innovation in our rock and concrete cutting products. Our expertise in engineering and our quality, US manufactured tunneling, mining and construction equipment is unparalleled to others in the industry.
KAMY is the leading manufacturer of roadheaders in the weight class of 13-100 tons weight. Our roadheaders offer interchangeable cutter heads, both transverse and axial and are custom engraved for each project. 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.
Technology led the establishment of the quality assurance after-sales service, improve the management system.
Production license of the product ensure that the license number, approval date and expiration date.
Product packaging in line with national regulations, due to packaging damage caused by the products borne.
Any difficulties encountered by customers, we will do our best in the first time to provide perfect service.
