Loading Specification:
The document outlines the specifications for wheel-loads, which refer to the weight of a vehicle and its typical load based on wheel type. Pneumatic tyres distribute the load, while solid tyres create a greater point load, suitable only for Class E600 and F900. Dynamic loads consider vehicle movement, speed, braking, and traffic frequency.

Compliance:
The specifications comply with BS EN 124:1994, which categorizes loads into dynamic and static. Static loads are vertical loads from stationary vehicles.

Load Classes:
The document provides a classification of loads affecting grates according to BS EN 124:1994:

• Class A15: For pedestrian areas, house drains, and park walkways.
• Class B125: For public footways and car porches, suitable for vehicles up to 3 tonnes.
• Class C250: For curb-side grates in heavy vehicle parking areas, suitable for vehicles up to 5 tonnes.
• Class D400: For carriageways and parking areas for heavy vehicles, suitable for vehicles up to 11.5 tonnes.
• Class E600: For areas with high wheel-loads like docks and airfields, suitable for vehicles up to 20 tonnes.
• Class F900: For areas with particularly high wheel-loads like airport taxiways, suitable for vehicles exceeding 20 tonnes.
