Can a hydraulic cylinder be used in place of a motor in an electric-hydraulic lifting system?

No, a hydraulic cylinder cannot be used in place of a motor in an electric-hydraulic lifting system. A hydraulic cylinder is a component that converts hydraulic pressure into linear motion, while an electric motor converts electrical energy into mechanical energy. In an electric-hydraulic system, the motor drives a hydraulic pump, which generates the pressure needed to actuate the cylinder. The motor is essential for providing the power source, and the cylinder is the actuator that uses this power to perform work. Replacing the motor with a cylinder would result in a system without a power source, rendering it inoperative.
