Patent ID: 6938716

Claim:
A method for preventing rollovers of a moving concrete mixing truck, the concrete mixing truck of a type having a cab, a chassis, and a drum for mixing concrete supported by the chassis, the drum attached between a front pedestal and a rear pedestal connected to a frame of the chassis wherein a drum motor controls rotation of the drum, the method comprising: rotating the drum in a clockwise direction at a speed based upon a transmission speed of the concrete mixing truck; sensing input data representative of operating conditions of the concrete mixing truck; comparing the input data relative to stored data indicative of a rollover to determine whether the truck is in a potential rollover condition; and initiating a corrective action unrelated to a speed of the truck based on the compared data to prevent a rollover of the truck, wherein the step of initiating a corrective action comprises transmitting a signal to a drum relief valve associated with a hydraulic line to the drum motor.
