Features
RockySea Petro has developed a special workover rig chassis range from 6X6 to 14X14, which is compatible with the entire series of XJ250 to XJ850 workover machines. It can operate in various terrains such as roads, deserts, mountains, and swamps, with strong driving power, good off-road performance, and can work in the range of ambient temperature -45 ℃ to 50 ℃.
Besides,the company also developed a desert off-road carrier. The driving type is 8x8, with an upper engine and a biased flat cab. It adopts a heavy-duty drive axle and is equipped with 29.5-25 tires.
Currently, self-propelled carriers and trailers of RockySea have been applied in many oil fields both domestically and internationally.
Description
Main structure of the Self-propelled carriers and trailer for truck-mounted Workover rig includes cab, frame assembly, suspension assembly, axle assembly, transmission system, braking system, steering mechanism, and electrical system. The following will briefly introduce each component.
1. The frame assembly is a specialized frame for heavy-duty drilling rigs, with an overall frame structure.
2. The cab is a flat head structure with a single driver's seat.
(A) The longitudinal beam and tail beam are made of high-quality high-strength 16Mn I-shaped steel. The lower edge of the longitudinal beam is welded with reinforcement plates to enhance the bending strength of the frame. The outer sides of the web plates of the two longitudinal beams are arranged with liquid and gas pipelines.
(B) The frame is equipped with four hydraulic support legs, front and rear trailer hooks, and various bracket supports.
(C) The frame is made of rectangular steel pipes, reinforced by several diagonal supports. The rear frame is equipped with a work walkway for easy operation, inspection, and inspection by operators.
3. Suspension assembly:
There are usually three suspension methods used:
(A) The front axle is suspended with steel plates.
(B) The other bridges are floating bridges, suspended by air springs.
(C) The middle and rear axles are suspended with steel balance beams.
4. Axle assembly: All axles are heavy-duty type.
5. Transmission system:
The power is transmitted through the transfer case, and the front and rear axles, as well as the winch, are respectively controlled by sliding clutches. The clutch of the front axle is controlled by the driver in the cab, while the transmission clutch of the rear axle and the transmission clutch of the winch on the vehicle are controlled by a lever to ensure safety.
6. Braking system:
This chassis adopts a pneumatic transmission braking method, consisting of two parts: foot brake (service brake) and hand brake (parking brake).
RockySea Petro: A Pioneer in Self-propelled carrier and tralier Manufacturing in China
Self-propelled carriers and self-propelled trailers are the foundation of mobile drilling and workover operation.The self-propelled chassis of RockySea Petro have been specially optimized, with the advantages of flexible mobility, strong off-road ability, and suitable for driving in complex areas such as muddy areas, deserts, and mountainous areas.
1. Self-propelled carriers and trailers for Mobile Workover rig of Sanajck have short body with small turning radius, which effectively save the operation area.
2. Carrier and tralier of RockySea Petro can match with various workover rigs from XJ250 to XJ850.
3. Working temperature range from -45℃ to 50℃ to fit harsh environment.
