TERRA-JET 8522 S
HDD třída: 20 - 25 tun
Horizontal directional drilling with the TJ 8522 S
Service friendly
-
The S-Series is designed to be extremely service friendly and reliable. All hydraulic components are easily accessible for servicing. The engine cover is made of glass fibre reinforced plastic (GRP) and can be lifted up to 45°, supported by gas-filled struts. They can also be lifted off completely allowing the best access to all components. The electric components are assembled in the central control panel inside of the cabin with easy access.
The Drivers' Cabine
-
The Premium model of the TERRA-JET 8522 S is equipped with a comfortable driver’s cabin, which sets new standards. The cabin has all round tinted glazing, with the machine side being glazed in a single uninterrupted panel. This allows the operator to see every detail of the drilling machine. Large windscreen wipers with jets clean the front and right panels. Additionally the drilling fluid pressure inside the drill rods is automatically released just before each drill rod change, preventing bentonite from being splashed onto the glazing.
The operator sits in a comfortable operator’s seat, which can be adjusted to suite the body shape and weight of the operator. The operator’s cab is wide allowing the seat to rotate 180°. The drill operator can drill looking in the drilling direction, or he can rotate the seat to be at right angles to the drill and observe every detail of the drilling machine.
Ergonomic operator's station
-
The drill operator drives and operates the HDD machine using the two multifunctional joysticks installed in the left and right armrests of the operator’s seat. Driving using the joysticks allows instantaneous control and smooth movement of the TERRA-JET.
A large touch screen with on-board computer is installed in the driver’s cabin. The monitor displays all vital information needed at any instance, and is controlled by finger touch on the screen.
The on-board computer updates and saves all relevant machine data every two seconds updating the operator on the essential drilling elements. This data may be transferred to a laptop for later evaluation and provides essential data for efficient service diagnostics. Additionally a bore log can be printed for each bore as regulated in the German specification DVGW 321. The bore log shows the torque, the drilling forces, the drilling fluid volume and pressure for each metre of the pilot bore and backreaming undertaken.
ADBSe
-
The TERRA-JET 8522 S is equipped with an electronic Automatic Drilling and Backreaming System (ADBSe).
This patented system automatically and within milliseconds adjusts the working speed of the drill to suite the ground conditions. In soft ground the drill operates at maximum speed, in hard ground slowly, but always at the optimum speed.
This allows the operator to operate the drill at maximum efficiency in a controlled and relaxed manner and prevents the drill rods and drilling tools from being overloaded. During the pilot bore the ADBSe controls the thrust force. If the drill head hits an unexpected obstacle, the ADBS stops the drilling speed immediately and drills very slowly through the obstacle. All automatically!
