Workover Rig


Light-duty mobile workover rigs

* This kind of workover rigs are designed and manufactured in accordance with API Spec Q14F7k8C and technical standards of RP500GB3826.1GB3836.2 GB7258SY5202 as well as“3C” compulsory standard.

* 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 Q14F7k8C and technical standards of RP500GB3826.1GB3836.2 GB7258SY5202 as well as“3C”compulsary standard.

* The whole rig structure is compact, highly integrated, and requires a small space for installation.

* The heavy-duty chassis are 8×610×812×814×8 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.
