Product Detail
The electrical-drive trailer-mounted drilling rig series
* 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.
