Abstract
Dump truck tag axle suspension control. A method of controlling a tag axle suspension includes activating a pusher suspension lift switch; and engaging a steer lock on the tag axle suspension, thereby preventing steering of the tag axle suspension, in response to the lift switch activating step. Another method includes activating a switch to thereby begin operation of a hydraulic pump; and engaging a steer lock of the tag axle suspension, in response to the switch activating step. Yet another method includes applying pressure to a bed lift actuator; sensing the pressure applied to the bed lift actuator; and applying pressure to a tag suspension load actuator, thereby transmitting a load from a frame to a tag axle via the load actuator, in response to the sensed pressure applied to the bed lift actuator reaching a predetermined level.
