A supermarket in an industrial production site is the location where a preset standard inventory is kept to supply downstream processes.


Supermarket trolleys or SAG trolleys, short for Supermarket and Assembly Goods, are an innovative and versatile solution for the efficient management of materials within a production plant. Designed to optimise material flow, these carts have become indispensable in many industries due to their ability to improve internal logistics and support the principles of Lean Manufacturing.

What are SAG trolleys?

SAG trolleys are essentially mobile containers used for transporting and handling components required for assembly and other production operations. These carts function as mini mobile warehouses that can be easily moved around the plant, allowing materials to be organised and supplied quickly and neatly.

What are SAG Trolleys Used For?

  1. Transporting Materials: SAG carts are used to transport components and materials from storage areas to production lines, ensuring that everything you need is always at hand.
  2. Space Optimisation: They help keep the work area clean and organised, reducing clutter and optimising available space.
  3. Assembly Support: Provide a continuous flow of components for assembly lines, improving operational efficiency and reducing downtime.

How do they integrate into Production Logistics?

SAG trolleys integrate seamlessly into production logistics in several ways:

  • Kanban systems: Used in combination with Kanban systems, SAG trolleys ensure that materials are replenished in a timely and continuous manner, maintaining a steady and well-organised workflow.
  • Lean Manufacturing: They support the principles of Lean Manufacturing by eliminating waste, optimising movement times and reducing waiting times. This helps to improve productivity and reduce operating costs.
  • Flexibility and Adaptability: Their ability to be easily adapted to different production needs makes them extremely flexible, allowing them to respond quickly to changes in production requirements.

Advantages of SAG trolleys

  1. Operational Efficiency: Reduced search and material handling times, improving overall productivity.
  2. Ergonomics: Designed to facilitate manoeuvrability, reducing physical effort and improving operator safety and comfort.
  3. Organisation: Keeps the work area clean and well organised, reducing the risk of accidents and improving the quality of work.
  4. Reduced waiting times: Ensure that materials are always available when needed, avoiding delays and interruptions in the production process.
  5. Durability and Robustness: Built to withstand heavy loads and daily wear and tear, they guarantee a long service life and minimal maintenance.

In conclusion, Supermarket trolleys are an essential component of any production facility that aims to improve efficiency, productivity and operational safety. Their integration into internal logistics, combined with the principles of Lean Manufacturing and the Kanban system, makes it possible to optimise material flow, reduce waste and significantly improve production performance.
