Abstract
A hydraulic system for an auxiliary load transfer device pivotally connected to the rear of a truck includes a sequence valve for preventing the build-up of excess fluid pressure in the main hydraulic line between a pump and a hydraulic cylinder that operates the load transfer device. The sequence valve is operable in response to the difference in pressure between the main hydraulic line and control pressure that controls the output pressure of the pump. The sequence valve opens to direct fluid from the main hydraulic line to tank to prevent the rear wheels of the truck from weaving or wandering during travel.
