Light-duty mobile workover rigs
This kind of workover rigs are designed and manufactured in accordance with API Spec Q1、4F、7k、8C and technical standards of RP500，GB3826.1、GB3836.2 GB7258，SY5202 as well as“3C” compulsory
The whole unit structure is compact and adopts hydraulic + mechanical driving mode, with high comprehensive efficiency.
The workover rigs adopt II-class or self-made chassis with various to meet the user’s different requirements.
The mast is front-open type and with single-section or double-section structure, which can be raised and telescoped hydraulically or mechanically.
Safety and inspection measures are strengthened under the guidance of the design concept of “Humanism Above All” to meet the requirements of HSE

Heavy-duty mobile workover rigs
This kind of workover rigs are designed and manufactured in accordance with API Spec Q1、4F、7k、8C and technical standards of RP500，GB3826.1、GB3836.2 GB7258，SY5202 as well as“3C”compulsary
The whole rig structure is compact, highly integrated, and requires a small space for installation.
The heavy-duty chassis are 8×6、10×8、12×8、14×8 constant- drive and self-propelled, equipped with hydraulic steering system and have a good capability of passage and cross country.
A good and reasonable assembly of CATERPILLAR engine and ALLISON transmission box can supply a high driving efficiency and increase safe performance.
Band brake or disc brake is applied for the main brake and the air disc brake/water brake or FDWS is used for auxiliary brake.
The compound box for rotary table has a function of forward-reverse speed shift gears, which can be suitable for DP’s rotary operations. The anti-torque releasing device can be used to release the deformation energy of the DP safely.
The mast is front –open type, with double- section structure, which can be telescoped, raised and extended hydraulically.
The drill floor is twin-body telescopic type or with parallelogram structure, which is convenient for installation and transportation. The dimension and height of the drill floor can be designed according to the user’s requirements.
Safety and inspection measures are strengthened under the guidance of the design concept of “Humanism Above All” to meet the requirements of HSE.
