  • Horizontal acceleration, lifting speed, and fork speed parameters are optimized for efficient and safe operation.

Design and Safety Features

  • Finite element analysis and theoretical calculations ensure structural integrity, static and dynamic stiffness, and strength.
  • Low running noise achieved by using H steel rails and polyamine running wheels.
  • Compact design with low center of gravity and anti-overturn mechanisms on hoisting and running mechanisms.
  • Personnel safety ensured by fence doors with electrical switches preventing unauthorized entry during faults.
  • Equipment safety includes long-stroke hydraulic buffers capable of handling 100% collision speed with deceleration less than 4 m/s².
  • Additional safety features on X3 model include slack rope overload protection, speed limit anti-drop devices, and shear force measuring sensors.

Installation and Maintenance

  • Factory pre-assembly of columns and lower beams reduces on-site installation time and improves accuracy.
  • Compliance with Chinese standards for installation and maintenance of automated storage and retrieval systems.
