Trailer-mounted drilling rig ZJ30 is developed with help with American engineering company. It features full digital vector control, AC-DC-AC driving, hydraulic/air/electric control and full trailers movement (composed of 13~15 trailer-mounted modules depending on the different configurations)
- Driven by VFD motor
- High-efficiency hydraulic disc brake system
- Independent drive for drawworks and rotary table
- Operatio controls are all centralized in the driller's room
- Two-section K mast
- Top drive system and hydraulic rotary table can be equipped
