  • State-of-the-art safety technology, especially in the area of heavy-duty overhead conveyor systems (overhead work), is enabled by the high-performance MOVISAFE® safety controller of the type PFF-HM31 – with the safety functions:
    • Safely limited speed (SLS) and
    • Safely limited position (SLP) for travel and lifting axes
    • Safe direction of rotation (SDI) for swivel axes
    • State of the art safety functions for motion axis
    • Safe communication with the higher-level system controller
  • MOVIVISION® system software for simulation/emulation, virtual startup, visualization via human machine interface (HMI), permanent monitoring and real-time diagnostics
  • Gear units and gearmotors: More than 2000 gearmotors from SEW-EURODRIVE are in use.

  • Maximum flexibility and ergonomics for the workers, as the body is presented at the optimum height and angle during the assembly process.
  • High safety level during overhead work under suspended load, thanks to the innovative safety concept in particular with safely reduced speeds and position detection at all workplaces.
  • System availability from day one thanks to the MOVIVISION® software tool, which is already used in the planning/engineering phase for simulation and emulation and for virtual startup and enables direct data download to the control components.
  • Significant reduction of real startup due to prior simulated virtual startup.
  • Production data is carried in parallel on the mobile conveyor system.
  • Production speeds can be adjusted at any time at the push of a button.
  • Diagnosis in real time.

Comments from our staff

"One of the most important benefits is the great ergonomics..."

"In my opinion, one of the most important advantages of the SEW-EURODRIVE drive system is its great ergonomics. In the past, our workers had to raise their arms to get the job done. Now, thanks to the tilt function, they can work in a posture that is much better for their health and reduces workload."

Mr. Chen Meisheng (Workshop Manager, Final Assembly Hall - Jinkang)

"The drive system is extremely flexible..."

"The drive system from SEW-EURODRIVE is extremely flexible. These advanced drive systems make it more convenient and flexible for us to produce new models or adjust our production lines."

Mr. Chen Meisheng (Workshop Manager, Final Assembly Hall - Jinkang)

"Different models on the same final assembly line..."

"Our products include different types of electric cars, including REEV (Range Extended Electric Vehicle) and BEV (Battery Electric Vehicle). SEW-EURODRIVE's solutions have enabled us to assemble different models on the same final assembly line. Overall, our cooperation with SEW- EURODRIVE is very smooth and trustworthy."

Mr. Chen Meisheng (Workshop Manager, Final Assembly Hall - Jinkang)

"Safety of equipment and employees is our top priority..."

"The safety of an industrial control system is an important part of the automotive industry. An intelligent and digitized system is essential for this. If a technical problem were to cause a production stoppage, we would have an enormous loss. Therefore, the safety of the equipment and employees during production and operation is our top priority."

Mr. Zeng Jian (Safety Engineer, Final Assembly Hall - Jinkang)

"... not only smart, but also super safe."

"The system solution from SEW-EURODRIVE is not only intelligent, but also super safe. It can effectively reduce risks in production, creating an advanced safety control system for the entire life cycle."

Mr. Zeng Jian (Safety Engineer, Final Assembly Hall - Jinkang)

"... a very safe, extremely reliable and environmentally friendly production"

"With the MAXOLUTION® system solution from SEW-EURODRIVE, the safety monitor is integrated into the system, allowing the entire system to be continuously monitored. This guarantees the highest level of safety for our employees and plants. Thanks to its proven technology, SEW-EURODRIVE has provided us with very safe, extremely reliable and environmentally friendly production. This allows us to improve efficiency and shorten the production cycle time according to our schedule."
