To eliminate the crane energy, there is a choice of 3 types of transducers:

• Rubber or Cellular plastic buffer
• Hydraulic cylinder
• None required, with sufficient energy absorbers on the crane.

The following data are required for the design of an impact buffer:

Energy absorbers:

• H = height from the centre of the crane’s contact point to the top of the rail profile.
• P = Impact force in kN.

*  If P is not known, it is calculated from the mass and speed of the crane. m = the mass of the crane. v = the maximum travelling speed.

Apart from bump stops for crane tracks, Bemo Rail can also supply buffer frames for railway tracks.
