Understanding Loads Affecting Grates:
Static Loads refers to load applied vertically to the grating with no other movement, such as load from a stationary vehicle.
This is classified as in BS EN 124:1994 Test-loads Table:
Wheel-loads refer to the weight of the vehicle and its typical load depending on the type of the wheels. Pneumatic tyres spread the load like the test-block in the illustration and solid tyres post a greater point load, which is only recommended for Class E600 and F900. Vehicle movement, speed, braking and traffic frequency are the consolidated consideration of dynamic loads.
