40 ton self aligning welding rotator

40 ton welding rotator is one of models among Fengwei made self aligning turning rolls. Likewise, the model consists of 1 power and 1 idler, each can load 20 ton of cylindrical objects respectively. It is free to puzzle around 1 power with several idlers based on work flow request.



Welding rotator is suitable for pipes or cylindrical objects with a diameter range between 600mm and 4200mm, which automatically adapts to tanks while loading. The rotator is operated by hand monitor which is optional for cabled or wireless. Both are convenient to control the start, stop and speed regulation of the rollers. The hand monitor can control the rotation speed, start / stop, forward / reverse rotation and motorized movement (if selected) in real time. It is suitable for welding, cutting and other fabrication of slender and heavy workpieces. Reduced labor cost and higher productivity are basic advantages.

High power, large output torque, independent r&d of control cabinet, with wireless transmission, remote speed regulation and remote digital display, greatly improves the safety. If space and cost limitation, cabled hand monitor to operate welding rotator is also a good choice.

40t self aligning welding rotator is set as DC frequency conversion stepless speed regulation and wide speed adjustment range. There are two sets of rotating wheels (8 wheels in total), which automatically stretch according to the workpieces diameter, increasing the diameter range of the applicable workpiece. The structure is compact, simple and light, and can meet the needs of different working environments.

Fengwei Machinery welding rotator is widely used in wind power, pressure vessel, petrochemical, pipeline, steel structure, boiler, shipbuilding, waterwheel tank, oil tank truck, surfacing repair and other industries. The factory can also design and customize various types of welding rotator according to users' needs. The utility model has the advantages of convenient application and use, strong wheel performance, not easy to lose rotation during operation, and beautiful appearance. Automatically complete welding operation.

Worldwide Distribution

Welding rotators, made by Fengwei Machinery are available to distribute worldwidely with our partners aross Europe and South East. Fully guranteed and warrantied for years.

We are also looking for local agents of welding rotator to cooperate with, fully technical support and on time product distribution.

Application Field

  • Petrochemical Industry

  • Environmental Protection

  • petrochemical industry

    The petrochemical industry plays a crucial role in enhancing the growth and economy of the world. Additionally, petroleum products produced in offshore and onshore exploration, refining, and oil production have also increased, resulting in increasingly complex waste production. This industry is a vital source of inorganic toxic and organic materials. 

    For the run of the industries present worldwide the top-quality equipment is mandatory. Several types of machinery producing industries are present worldwide but choosing the right one is a little confusing. Don't worry; we are here for your help. Giving the right solutions and shipments to your industry is our duty.

    Here are 3 must haves of welding automations for the fabrication process in the petrochemical industry:

    1) Conventional welding rotators

    2) fit up welding rotators

    3) welding manipulator.


  • Wind towers have saved 30% of nonrenewable energy while producing electricity. Today, there are hundreds of wind farms and sea areas are having thousands of wind towers. They hold the generator or dynamo blades, which are tones of weight. These wind power infrastructures are standing strong due to the use of welding rotators, welding manipulator, and welding positioners to be a tank assembly line. Experts in technology and engineering make them.
