Truck mounted drilling rig

• This kind of drilling rigs are designed and manufactured in accordance with API Spec Q1, 4F, 7k, 8C and RP500, GB3826.1, GB3836.2, GB7258, SY6584 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 move ability 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.

Electrical-drive trailer-mounted drilling rig

• This kind of drilling rigs are designed and manufactured in accordance with API Spec Q1, 4F, 7k, 8C and RP500, GB3826.1, GB3836.2, GB7258, SY6584 standards as well as "3C" compulsory standard.
• This kind of the drilling rigs consist of trailer-mounted main unit, drive system, drill floor, DP slide way, control system and auxiliary system, etc.
• The drawworks and rotary table are driven by DC brushless–excitation motors and the driving control is realized by digital AC-SCR-DC system
• The hydraulic disc brake is for main brake and FDWS is for auxiliary brake.
• The derrick which is front- open type and two–section structure with an inclination angle or erective sections can be lifted up or fallen down and telescoped.
• The substructure with the height of 5.5 m has a parallelogram integral structure with two sections supported by 6 setbacks, which can be risen spirally.
• The structure is simple, but easy for installation and movement and the transmission is reliable.
• Safety and inspection measures are strengthened under the guidance of the design concept of "Humanism Above All" to meet the requirements of HSE.
