The YT28 air-leg rock drill is suitable for drilling operations on medium-hard or hard rock, with strong adaptability to working conditions.
Product Advantages
-
Energy-efficient, highly efficient, reliable and durable
The product is energy-efficient and highly efficient, with long part service life, sturdy and durable, easy to maintain, and good reliability.
-
High parts interchangeability
Parts are interchangeable with those of machines of the same model, so users' interests are not compromised when replacing the product.
-
Simple operation and convenient use
The operating mechanisms are centralized, and startup is flexible. It adopts air-water linkage, rapid air-leg retraction, air pressure regulation, etc., making it convenient to use. It has a strong hole blowing and washing function, and its drilling torque is large, superior to similar products.
-
High efficiency and good economic results
The control handles are centralized on the handle body. The mechanism is novel and convenient to operate. The equipped muffler can effectively reduce noise and freely change the exhaust direction, improving on-site working conditions. Compared with rock drills of the same type: lighter weight, lower noise, higher efficiency, and better economic results.
