Precision Control: They work in tandem with the truck's load-sensing hydraulic system. This system provides hydraulic oil flow and pressure proportional to the steering demand. This allows for smooth, precise, and responsive control, whether making a minor direction change on a haul road or a sharp turn at the loading face.
Stability and Oscillation Damping: The cylinders, along with the articulation joint, play a role in the stability of the machine. Some systems allow a degree of "frame oscillation," where the front and rear frames can pivot slightly vertically to keep all wheels in contact with uneven terrain. The steering cylinders and their mounting help manage this movement while maintaining steering integrity.
This 617-0748 steering cylinder is used for 775G 775 773G caterpillar truck.
