Explorer 4 - Electro-Hydraulics Training System

TII

SKU: EXP4-B

Regular price $13,595.00

The EXP4 is a complete Industrial Electro-Hydraulics training system with proportional and joy stick control. This trainer is designed to demonstrate electrical control of hydraulic systems in a user-friendly, application-oriented setting. Electrical sequence and logic control is done using switches, sensors, joystick (mimic mobile hydraulic operations), and control valves.

Our curriculum begins with a fundamental review of basic hydraulic principles followed by electrical graphic communication symbols. Additional topics focus on typical electro-hydraulic applications found in today’s industry. This system covers electro-hydraulic open loop proportional control technology in its three areas of instruction: Physical Properties and Fundamentals, Applications, and Electro-Hydraulic Control.

System components are mounted in a configuration to replicate Open Loop proportional speed and position control of electro-hydraulic manufacturing systems using a hydraulic motor and linear actuator
Industrial grade electronic, electro-hydraulic, and hydraulic components
Speciality components available to expand capabilities of the system
