When procuring a tricycle assembly line, you must prioritize automation levels and load-bearing capacity. Ensure the conveyor system (whether chain, slat, or overhead) can support the maximum weight of a fully assembled tricycle, typically ranging from 150kg to 500kg. Key technical components include variable frequency drives (VFD) for speed control, PLC control systems (such as Siemens or Mitsubishi) for synchronized movement, and pneumatic lifting platforms at workstations to ensure ergonomic assembly.
