摘要： This invention relates to a method and apparatus for maintaining equal air pressure in a pair of tires on a work machine. The invention provides a valve body with a pair of piston chambers. A piston is reciprocatably positioned within each piston chamber, the pistons are biased toward a first closed end of the piston chambers. The closed end of each piston chamber is connected by a passageway to one of the tires. Each piston chamber is additionally fluidly connected to the other piston chamber. When the air pressure in each tire is above a predetermined amount the pistons are moved away from the closed end of the piston chamber and airflow is permitted between the piston chambers thereby balancing the tire pressures. If the pressure in either tire is below the predetermined minimum, the piston in that respective piston chamber moves toward the first end to block, airflow between the piston chambers.

摘要： A process of enabling and providing a service for improving haulage efficiency in a haulage system includes identifying a customer who may benefit from the service. Haulage vehicles of a fleet of haulage vehicles are equipped with a system for monitoring haulage parameters of the haulage vehicles. Equipment for gathering data on the monitored haulage parameters and for gathering information on haulage vehicle location along haul roads is provided. Target haulage parameters which result in desired haulage system performance are determined. The data is analyzed and deviations of actual haulage system performance from desired haulage system performance are determined.
