Column and Boom

Column and Boom, (also called C&B) are mainly composed of a column, boom guide wheel, lifting mechanism, boom retracting mechanism, etc.



1. Column guide rail material of Column and Boom is made of 45 steel, with annealing treatment after welding. Such fabrication has high rigidity and intensity, to ensure long-term performance and service life.

2. Boom frame adopts rectangle boom guide rail structure way (double guide rail “I” type), guide rail material is made of 45 steel, with annealing treatment after welding. Very robust.

3. Boom retracting and lifting mechanism both adopt chain cable, simple and beautiful. The lifting mechanism is mainly composed of a lifting motor, lifting reducer, lifting chain, etc.

4. Boom horizontal movement is realized by motor, equipped with a limited switch for all movement; adopts frequency conversion speed regulation.

5. Lifting mechanism is mainly composed of lifting motor, lifting reducer, lifting chain, etc.

6. All axis series parts are under, finishing after tempered.

7. Boom lifting mechanism adopts brake motor, worm, and gear reducer and chain wheel to realize lifting movement. Safety confirmed.

8. Head of the boom is optional for configurations, such as robotic arm, welding head, laboratory, etc.

Can C&B equip with other functions?


C&B  itself is only an automation result by mechanical design consisting of automatic movement, i.e. up and down, left and right. Per industrial request, we added extra functions into the column and boom to become a complete set of the processing machine. It is optional to equip with the robotic arm, welding gun (SAW, TIG, MIG, Plasma, etc), abrasive function and etc. Fengwei can offer you C&B only or a completed set per your request.

Application Field

  • Petrochemical Industry

  • Environmental Protection

  • Steel Structure

  • Power Tower

  • 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.

  • Steel structure has become an indispensable material type used in modern construction industry. Due to the feature of environmental friendly, it has been widely used in construction, such as steel structure factory building, ordinary steel construction building, boiler, pressure vessel, shipbuilding, electric power, petrochemical, petroleum engineering machinery, bridge construction, metallurgical machinery industry, wind power and power tower etc. The bird's Nest building in Beijing, China, is a classic masterpiece of steel structure architecture.

    The h-beam steel production line made by Fengwei Machinery is a highly automated steel structure production line which composes of CNC flame cutting machine, h beam assembly machine, h beam welding machine, and h beam straightening machine. It greatly reduces labor intensity and production costs, improves production efficiency.


  • The application of automatic welding and cutting equipment in the manufacturing process of steel tube tower can thoroughly optimize and upgrade the original production process. The traditional production mode adopts the operation of lifting semi-finished products, which requires a special person to be responsible for the lifting and operation of semi-finished products. It has high requirements on the environment and working space, which not only requires a lot of manpower and material input, but also has high labor intensity with low production efficiency. Different from the traditional production mode, the automatic cutting equipment integrates online monitoring, automatic upload and offload raw materials and other automatic functions, can reduce the workload of workers and work intensity, thus greatly improving the production efficiency. The production lines of cutting, pairing and welding can cover each area of the workshop, which can be operated as a whole or independently in each area.
