“The floor surfaces in our buildings were not sufficiently flat and level to allow swift and safe operations in the narrow-aisle warehouses. After comparing a variety of options and proposals, we decided to commission your company* to carry out grinding work in two lanes each of our 38 m and 90 m narrow aisles. The height of the top shelf is 10 m. The narrow-aisle forklifts we use are guided along lateral tracks.

Prior to commencing the work you had referred to your new product, the Laser – Grinder® XPT, and suggested grinding the entire width of the aisle instead of only the travel tracks for the same price.** We agreed to this.

You commenced your work on the date agreed. Apart from the preparatory measures to be carried out by us prior to the commencement of your work, such as the provision of a mobile crane for unloading/loading operations due to the lack of loading ramps with dock levellers in the halls, as well as the provision of a 220-V power supply, a ¾” water connection and a waste skip, no other activities were required of us.

It was very helpful that the stored materials could remain in the storage shelves and that our production processes would not be inhibited.

The work was completed within the timeline agreed; in one of the warehouses it was necessary to work on Saturdays and Sundays as well.

The Laser Grinder® XPT created an automatically computed latitudinal floor profile that was calculated by an on-board computer system based on the measurement of the existing floor heights. With the exception of one particularly uneven spot in the original floor surface, the grinding depths were less than 10 mm. The original substantial difference between the heights of the forklift truck wheels was ground down to the smallest tolerances by an evidently highly sensitive laser in combination with a jolt-free hydraulic system.

During the grinding process, the sludge that was generated by the regulated addition of water to the concrete dust accumulating in the encapsulated tools was continuously vacuumed off. The diesel motor of the Laser Grinder® XPT did not emit any perceptible unpleasant odours during its use; no complaints about cold exhaust odours were received from the employees in Hall 65 when work began on Monday morning. According to the information in your quotation, you use a EURO-5-compliant diesel engine. For this reason, in our opinion and also from the perspective of today’s state-of-the-art health and environmental aspects, there are no reasons for concern regarding the use of the Laser Grinder® XPT in the interior of buildings.

Operation of our STILL narrow-aisle forklifts and all their functionalities can now continue without any restrictions whatsoever. The driving behaviour and resulting level of comfort, the obvious improvement in safety and the velocities that can now be achieved, even at great heights, confirm our opinion that the grinding work will lead to a sustainable reduction of operating costs.

We are glad to confirm that we are more than satisfied with the way in which the grinding work was performed, the technology used and the resulting flatness of the level surfaces.”

** At this time the central grinding head of the Laser Grinder® XPT was still in production so a separate centre track could no be ground. It was for this reason that the entire aisle width was ground for the same price as track grinding.
