THE TRAILER-MOUNTED DRILLING RIGS

1、These drilling rigs are designed and manufactured in accordance with API Spec QI 4F、7k、8C and RP500，GB3826．1、GB3836．2 GB7258，SY6584 standards as well as”3C”

compulsory standard.

2、These drilling rigs have the following advantages: reasonable-design structures and high integration, a small working space and a reliable transmission.

3、The heavy-duty trailer is equipped with some desert tires and large-span axles to improve the movement and the cross-country performance.

4、A high transmission efficiency and performance reliability can bemaintained by smart assembly and a utilization of two CAT 3408 diesels and ALLISON hydraulic transmission box

5、The drawworks is double-drum type, and a hydraulic disc brake is equipped as main brake and air water-cooling disc brake (Model EATON WCB324)is equipped as auxiliary brake

6、The derrick which is front-open type and has two-section structure with an inclination angle or erective sections can be raised up or lain down and telescoped

7、The substructure has a parallelogram integral structure for easy transportation and installation, which can be raised by 6 setbacks spirally,

8、These drilling rigs have desert adaptability design also have good anti-dust and high/low-temperature-proof performances.

9、Safety and inspection measures are strengthened under the guidance of the design concept of “Humanism Above All” to meet the requirements of HSE.
