Connecting surface quality requirements
INSTALLATION REQUIREMENTS
- Material quality “A”: Usually construction steel of minimum quality S355 is used
- Plate thickness “B”: Depends on stiffness of total construction. Plate thickness of connecting surface must be at least 40 mm
- Surface quality “C”: Required mean roughness of the connecting surfaces is 6.3 μm
- Planeness “D”: Maximum admissible planeness tolerance within each connecting surface is 0.05 mm
- Angular deviation to vertical axis “E”: Angle deviation of connecting surface to the vertical axis in both planes must not exceed ±2°
- Plane parallelism “F”: Upper and lower connecting surfaces to the weighbeam must be plane-parallel to within 0.1 mm
