Remove 300 m³ of soil from a cellar using conveyors.
A general asonry and structural work company asked us to restore a medieval cellar that had been filled in several decades ago.
The project involved clearing soil from an area of 100 m² with an average height of 3 m – representing nearly 300 m³ of soil to be removed.
Soil conveyors were the most rational and efficient solution for this project.
Customer needs.
Initially, the company used big bags to remove soil from the cellar. A mini-excavator filled the bags, which were then hoisted to the surface by a winch and dumped on the ground. The soil then had to be piled up again so that it could be loaded onto a tipper lorry and taken off the site.
This system worked, but it was time-consuming, required important human and material resources, and was physically demanding for the workers.
In one day, the company was able to fill a maximum of eight 3.5-tonne dump trucks. This was not enough for the customer. The objective was therefore to reorganise the site to increase speed and improve working conditions for the teams.
The proposed solution.
To meet this challenge, we proposed renting 4 Shifta conveyors. These conveyors are designed for transporting bulk materials in basements and confined spaces.
Compact, robust and mobile, these conveyors operate on a 220V power supply and enable the continuous transfer of spoil, rubble and soil over long distances. Their lightweight aluminium design makes them easy to install by two people, without any lifting equipment.
Each soil conveyor is equipped with a chevron belt able to transport materials at a rate of 90t/h, even when there is a significant difference in height.

Implementation of soil conveyors on construction site.
The distance between the cellar and the tipper lorry was approximately 20 metres. To cover this distance, four Shifta conveyors measuring 3 m, 4 m, 5 m and 6 m were deployed.
This configuration could have been different depending on the models available in stock.
This equipment, delivered assembled and ready to use, requires no unloading equipment. The integrated wheels and handles make it easy to handle and install independently.
The 6 m soil conveyor was used to cross an unstable area, while the 5 m conveyor was placed at the exit to achieve the ideal angle for loading the soil directly into the skip. The synchronisation of the conveyors ensures smooth operation. Simply stopping one of them is enough to interrupt the entire chain, ensuring total control of the flow and maximum safety on the site.
Benefits for the customer.
The results have exceeded the customer’s requirements. Thanks to the installation of the soil conveyors, 8 lorries are now loaded in 3 hours instead of 1 day.
This solution has significantly reduced the strain on teams, limited handling and optimised productivity. Workers have been able to focus on other tasks, reducing downtime and intervention costs. Removal has been carried out continuously, without overflow, waiting or excessive physical effort, improving both the quality and pace of the site.
Conclusion.
