Question

Essay about the relationship between payloads and axle height!

Answer 1

Axle capacities are limited either by the axle capacity or the legal weight limits, whichever is lower. 

Performing a weight distribution analysis can help in preventing building trucks that are overloaded in normal use and cause problems for users and for the equipment installer.

Overloads can shorten the life of a vehicle and its components. Overloads can also prevent compliance with weight laws and federal safety standards.Weight distribution is the amount of the total vehicle weight imposed on the ground at an axle, group of axles, or an individual wheel. The weight on a truck must be distributed on the axles to comply with the chassis manufacturer's axle ratings and weight laws.

The maximum payload is equal to the sum of the maximum axle loads.If the trucks carry maximum load weight on the rear axles, they will not be able to haul maximum payloads without exceeding the tandem-axle weight limit on the rear axles.

The configuration of tandem-axle logging trucks needs to be changed in truck designs so that it will provide the correct distribution of load weight and have the capacity to handle the front- and rear-axle loads needed for maximum payloads.

By distributing the payload weight in a way that both front and rear axle weights are maximized, the payloads can be increased. This would also reduce axle-weight overloads that can result in heavy fines being levied on truck operators.
