    Jan 16, 2018 · RE: Calculation of bearing pressure for heavy excavators. aeoliantexan (Geotechnical) 19 Jan 18 19:08. If the wheels have pneumatic tires, the usual approach is to assume the soil contact pressure is equal to the air pressure in the tire. Divide the load by the tire pressure to get the bearing area. The footprint is roughly elliptical.

  • How Mini Excavator Hydraulic Systems Work

    Mar 22, 2016 · "The higher the pressure gets in a system, the more the flow is reduced. So for example, if you wanted to equip an excavator with a felling head, which has a high pressure and flow demand, you would need to combine flow from multiple pumps. That produces the speed to turn the cutting wheel and the power to cut through a tree.
