Hydraulic vs. Pneumatic vs. Electric Actuation for Heavy Material Handling
Hydraulic, pneumatic, and electric actuation compared for heavy handling machines: force per bore, speed, stiffness, energy draw, line power density, and LOTO.
Mixed-Power Machines: Partitioning Hydraulic, Pneumatic, and Electric Axes
Splitting a heavy handling machine into hydraulic, pneumatic, and electric servo axes: force, flow budget, line routing, PLC control, and multi-source LOTO.
When an Electro-Hydraulic Actuator (EHA) Beats a Hydraulic Power Unit
When a self-contained electro-hydraulic actuator beats a central hydraulic power unit: throttling loss, regeneration, heat, duty rating, stiffness, and lockout.
