SMB System C
Data
Class C design
• The edge protection must be between the vertical
line A and perpendicular to the working surface B.
• The edge protection openings may not be more than
100 mm in one direction.
Corners
The attachments are designed to resist
loads in one primary direction. For this
reason, Combisafe always recommends
the use of two Safety Posts in the
corners, one in each direction.
Overhang
The maximum permitted overreach of
the SMB or FRB is ¼ of the distance
between Safety Posts. This presupposes that the guardrail or Steel Mesh
Barrier or Framed Barrier is connected to the Safety Post.
Wind load
Maximum wind load
The edge protection system can withstand a wind velocity pressure of
600 N/m2. This is equivalent to a wind speed of approximately 32 m/s.
WARNING!
Should the wind speed exceed this amount then the arrangement
may need to be recalculated to determine its fitness for purpose.
Adjustments may need to be made to the arrangement following
calculations.
Maximum working wind conditions
The edge protection systems can withstand a wind velocity pressure of
200 N/m2 under working conditions. This is equivalent to a wind speed
of approximately 18 m/s.
