Introdução do ProdutoThe MQT-130/3.2 pneumatic roof bolter drilling rigs is suitable for bolting operations in coal, semi-coal-rock and rock roadways with a roof Protodyakonov hardness coefficient f≤10, integrating drilling, resin mixing and bolt installation. This bolter has a compact structure, small size, light weight and easy operation. The optimized design of components further improves its torque, rotation speed and adaptability. Improvements to the leg valve and air valve simplify the structure and facilitate maintenance. To adapt to roadways with different cross-section heights, the MQT-130/3.2 pneumatic roof bolter is divided into three models (I, II, III) according to the leg height. Our company has developed roof-and-sidewall dual-purpose roof bolters to meet various mining requirements, allowing customers to select the appropriate model according to actual working conditions.Características do Produto
