Trailer-mounted Drilling Rig


* This kind of drilling rigs are designed and manufactured in accordance with API Spec Q14F7k8C and RP500GB3826.1GB3836.2 GB7258SY6584 standards as well as“3C”compulsory standard.

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

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

* A high transmission efficiency and performance reliability can be maintained by a smart assembly and a utilization of two CAT 3408 diesels and ALLISON hydraulic transmission box.

* The drawworks is double- drum type, with which the hydraulic disc brake is equipped as main brake and air water-cooling disc brake (Model EATON WCB324) is equipped as auxiliary brake.

* The derrick which is front -open type and has two –section structure with an inclination angle or erective sections can be lifted up or fallen down and telescoped.

* The substructure has a parallelogram integral structure for easy transportation and installation, which can be risen by 6 setbacks spirally.

* This kind of drilling rigs with desert adaptability design also have good anti-dust and high/low- temperature-proof performances.

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