Selection of grating panels for vehicle traffic

  • Q - total vehicle weight, with allowed payload [T]
  • P = a / b
  • a - value of the maximum pressure on the most loaded wheel
  • b - "a" increased by the dynamic factor (vibration, braking) [T]
  • A - area subjected to the "P" pressure [m x m]
  • RL - movement along the bearing-bars
  • RB - direction of movement perpendicular to the bearing-bars
Welded gratings, bearing-bars spacing 34,3 mm
