- The 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, and SY5202.
- The whole rig is compact, highly integrated, and requires a small space for installation.
- Type 8×6 heavy-duty chassis furnished with the rig carrier, complete with constant drive and self-propelled, equipped with hydraulic steering system and have a good capability of passage and cross country.
- A reasonable assembly of CAT 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 derrick is a two-section, front open derrick 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 will be designed according to the user’s requirements.
- Safety and inspection measures are strengthened to meet the requirements of HSE.
