Application
Developed with several patented technologies, the RL-CZ30 truck-mounted drilling rig can be applied into oil well drilling engineers with drilling depth lower than 3000m.
Features
-
This drilling rig is powered by two independent diesel engines, which can operate either separately or in parallel, ensuring high operational safety and ease of maintenance.
-
The unit integrates mature parallel-operation transfer cases and Allison transmissions, delivering reliable power distribution and smooth performance.
-
The drawworks is equipped with a pneumatically controlled, water-cooled disc auxiliary brake for enhanced safety and control during operation.
-
The rig features a derrick constructed from rectangular tubes, available in heights of 36 or 38 meters, offering robust support for deep drilling operations.
-
Mounted on a reinforced 14×8 chassis with pneumatic suspension on the rear dual-wheel driven axle, the rig ensures optimal load distribution, superior mobility, and strong cross-country performance.
-
Customers can choose between 5.5-meter and 6-meter foldable drill floors, with the option of an integrated driller's cabin for improved operational comfort and control.
-
A top-drive system is also available as an optional upgrade to meet diverse drilling requirements.
