LOAD CAPACITIES FOR EARTHMOVER SERVICE

(1)Excess Loads

Due to the specialized nature of Off-The-Road vehicle usage,loads in excess of those in the appropriate above-listed load tables are often encountered.

These excess loads result from items such as actual vehicle weight exceeding the design weight,varying density of materials, field modifications to the equipment, load transfer,etc.

Only under these conditions,the actual tyre load in service may exceed the above load ratings in the tables(R1,R2) for the tyre by an amount not greater than shown in the following table:

	Maximum Excess Loads
	Load	*Pressure
Radial Tyres	7%	14%

*When excess loads are encountered, cold inflation pressures must be increased to compensate for higher loads. For each 1% increase in load, the inflation pressure must be increased by 2%.

The inflation pressure should not exceed 800kPa (116psi).

(2)The Variation in Load Carrying Capacity with Speed
