Explorer 4 - Electro-Hydraulics Training System



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

Instrumentation Section

  • Constructed of a welded steel A-shaped frame with formed sheet steel shell
  • Modular design can be used as a stand-alone system or integrated into a bench configuration with other TII trainers
  • Components are either panel-mounted or attached to a sub-plate for easy T-slot adjustable mounting
  • Instrumentation Section includes: two pressure gauges (0 – 1500 PSI) for system and in-line pressure readings, two four-port manifolds (pressure and return)
