Schmalz aluminum overhead crane systems offer impressive low friction operation. A favorable weight-load ratio ensures that even heavy work pieces are handled effortlessly. The equal distribution of loads on all the supporting rollers prevents the transport trolleys from tilting. The modular design allows the crane system to be attached to any steel structure or other superstructure.

The load diagram can be used for reference when selecting the section size while taking a specific maximum load and the suspension distances into account. The suspension distances stated are based on a deflection of 1:300, the common value for calculating crane systems. Smaller deflection values such as 1:400 may be required for certain applications.
Example: With a maximum load of 200 kg and a predetermined suspension distance of 5,000 mm the profile SRA-140 is used. The maximum deflection is then 17 mm (5,000 mm / 300).
