4 | 10

The length of the base rails depends on the selected module width, maintenance 

aisle width and the number of module rows. 

The distance between "System Rail 18 at the bottom" and "System Rail 18 at the 

top" only depends upon the module inclination.  The first support should be 
placed at least 50 mm from the front edge of the base rail. The module frames are 
always flush at the top with the Rapid 16 module clamps.

The base rail length can be selected from the four standard lengths (2650, 
4200, 6000, 6300 mm) and combined with each other. The base rails can be 

connected with the internal connector, Item No. 129078-000. The maximum 
permissible field size has to be observed!

Mounting distances

Mounting Distances a and c as well as the lower projection of Modules b and d 
result from the module width. The dimensions can be determined as follows. 

Variant 13°

Variant 6°

The mounting times can be optimized by pre-assembling a series of base rails 

next to each other on mounting frames with the module supports.

way width

Distance a has to be adapted according to the width of the 

maintenance walk way.

The specification of the distances is based on the use of 

Rapid16 module clamps (module clamp length = 50mm).
