Introdução do Produto
The 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
- Unique waterproof design: The water jacket adopts enhanced sealing and drainage hole design, ensuring reliable water supply, protecting the gearbox, and doubling its service life.
- Easy to operate and simple to maintain: The split main shaft and split motor gear ensure smoother operation and easier maintenance.
- High power, large torque and high rotation speed: According to user tests and comparisons, our bolter delivers 30% higher efficiency and 40% longer service life than ordinary models.
- Stable operation and long service life: The gear-type pneumatic motor provides a strong guarantee for smooth operation and long service life.
- New air leg design: Dual exhaust and an optimized sealing structure ensure fast and smooth lifting and lowering of the air leg.
