A clean room is expensive, and this is why users always try to keep it as compact as possible. Consequently, clean room cranes must often be assembled, commissioned and later operated under confined space conditions.
In order to operate the maximum work surface with clean room cranes, they are approached to the interference contours as closely as possible.
In the meantime, 3D laser scanners are a common means to measure the contours of a clean room. With this technology, the interference contours of the later clean room crane can be gauged exactly to the millimetre.
ALTMANN has measured clean room cranes with a 3D laser scanner for some time, too. However, the specialist for clean room cranes treads a completely new path with the obtained data in this field: the geometry of a clean room can be directly transferred to the company's design software.
This enables ALTMANN to modell the customer's clean room crane in the virtual reality of the room. The main benefit is that the additional air otherwise required for construction, manufacturing and installation tolerances can be reduced to an absolute minimum. And as this allows designing the crane around the interference contour, the customer can finally be provided with more favourable approach dimensions.
Figur 1: The roller shutter of a high-speed door was recorded with the 3D laser scanner and displayed as a scatter plot in the software. The crane can thus be approached to the interference contour without installation tolerances.
Figur 2: The measurement data of the 3D laser scanner are directly transferred to the construction software, so that the clean room crane can be constructed in the virtual clean room.
