Double Speed Chain Pallets: The Space Revolution and Intelligent Core of Modern Manufacturing

​Spatial reconfiguration: an industrial revolution in vertical circulation systems​

Inside the new energy vehicle parts factory, a double-deck doubled-chain pallet system is being used to22 metres per minute.Conveying motor assemblies. Unlike conventional single-level lines, the upper level carries fully loaded pallets flowing to the assembly stations, while the lower level conveys the motor assemblies through theLift and return mechanismThe empty tray back to the starting point, forming a closed-loop system. This vertical layout to crack the manufacturing industry's "space paradox" - Guangdong, a home appliance enterprise transformation case shows that the use of this structure:

  • ​Site Utilisation Improvement 53%The space was freed up for 3 additional inspection stations.
  • ​Pallet cycle time compressed from 8 minutes to 4.2 minutes​
  • ​Daily production capacity jumps to 28,000 unitsThe failure rate has been reduced by 35%.

The core value lies in the synergistic design of the lifting mechanism: the cylinder lifts the pallet within 0.4 seconds, and the servo motor drives the rotating platform to complete 90° steering, with the error controlled within ±0.3mm. This "air relay" mode is more efficient than the traditional U-shaped line.Save on 47% FootprintThis is equivalent to achieving 1500m2 capacity in 800m2 of space.

Plate speed V = chain speed Vc × (1 + D/d)


Formed when D = 2d3x speed effect--An automobile production line test shows that when the chain is running at 7.5m/min, the pallet speed can reach 22.5m/min, which not only reduces the wear and tear, but also solves the contradiction between high speed and precise positioning.

​Ask yourself the core question.​

​Q1: Why are traditional U-shaped cables being replaced by double-deck doubler chains?​

Space efficiency is at the heart of this - the U-shaped line needs a diameter of 30 metres to achieve circulation, whereas the double-layer right-angle layout needs only 12 x 8 metres; and the return mechanism is more efficient than the robotic shift load.Four times faster.The cost is only 1/3.


​Q2: How to solve the chain deformation in the press-fit process?​

hinge onPressure Transfer Design: The bearing platform receives the pressure conducted by the support column (Patent CN202320439829.6), so that the doubling chain only bears a load of 15%, and the deformation rate drops by 80%.


​Q3: The direction of technology evolution in the next decade?​

in my viewSuperconducting magnetic levitation fusion technologyWill subvert the traditional - laboratory verification in -196 ℃ liquid nitrogen environment, tray suspension 0.5mm operation when the energy consumption drop 87%, which may give birth to theContactless fourth-generation speed chainThe mechanical wear and tear is completely eliminated.
