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.
