How does hydraulic articulation steering operate on an Articulated Dump Truck (ADT)?

Hydraulic rams push and pull the front tractor section relative to the rear frame around a central pivot point. The front wheels turn independently on steering knuckles powered by a rack and pinion system. Individual wheel motors reverse direction on one side like a track-mounted excavator. Rear axle steering rams rotate the rear wheels while the front wheels remain fixed.

Correct Answer:

Hydraulic rams push and pull the front tractor section relative to the rear frame around a central pivot point.
