The Core of Excavation: Understanding the Components of raise boring equipment
Unlock the secrets of Raise boring Equipment by delving into its core components. From drilling heads to powerful motors, this article provides an in-depth look at the components that make these machines formidable forces in the world of excavation.
Crawler raise boring machine hydraulic system with 40 Mpa high pressure has a number of advanced technologies such as constant power control, load - sensing control, multiple filtering proportional solenoid control and so on. In addition, the system stays ahead in mine field. The advanced advantages of higher intelligent degree, bigger power density, stronger anti–dirty ability and higher reliability can ensure that RBM effectively excavate for hard rock.
The control system supports two drilling modes (high accuracy drilling mode an speed drilling mode) and three operation modes (manual operation, wireless operation and wired operation). The user can select drilling mode according to accuracy requirement and geological conditions and select operation mode according to operating position and the actual situation.
By means of the automatic positioning technology and two hydraulic wrenches inserted dynamically, the operation that operators connect and break out drill pipes can be accomplished without being directed. The system greatly reduces working strength and saves auxiliary working time.
Crawler raise boring machine installs RCS intelligent control system with safety protection automatic operation, fault diagnose, data storage, internet communications, digital display so on ( See specification of RCS intelligent control system)
