Industrial Hydraulics
EXPII
The Explorer II is a comprehensive maintenance training system for Industrial Hydraulics. This system provides the components and hands-on training required to effectively troubleshoot and repair hydraulics systems used by today’s employers. TII’s curriculum covers hydraulic technology in its four areas of instruction: Fundamentals, Applications, Physical Properties and Maintenance. We begin with the fundamentals which can be used as either an introduction or a review of key principles. Additional sections focus on different types of valves, cylinders, and hydraulic devices like hydraulic jacks and regenerative circuits.
Our training system is accompanied by a comprehensive student manual and instructor’s guide with 42 units of activities and instructional support. Each of the four necessary levels of instruction includes background study of the topic, observational and hands-on experiments, application exercises, and mathematical formulas for proving results.
- Lockable storage area provides space for manuals and additional components
- Specialty components available to expand capabilities of the system
- Mounting hardware included
- Portable, rugged design
