Weight and volume control: Hydraulics make up 20-30% of total weight. Integrated parts cut portable rigs to 15kg, carried by two people. Large rigs streamline layouts to fit vehicle dimensions.
-
Power source flexibility: Hydraulics work with diesel, electric or gasoline engines. Grid areas use quiet motors; remote sites rely on diesel—one rig switches seamlessly.
-
Hydraulic control for tracks/tires: Hydraulic motors drive movement. Track rigs turn in place, climb 30° slopes. Tire rigs steer easily, moving at 50km/h. A track rig adjusts motor speeds to avoid getting stuck in swamps.
