LunchBox Sessions

Bite-Sized Industrial Training

Characters right
Lessons, simulations, and videos that work on computers and tablets.
We help you develop Hydraulic & Electrical troubleshooting skills.

LunchBox Sessions is a new kind
of online industrial training.

It's full of working simulations that you can play with,
step-by-step lessons that teach and test you,
and schematics that come to life.

Grab the controls. Power the solenoids.
Cause a pressure spike. See what happens.
We give you
truly interactive training.

Follow the paths in series and parallel circuits.
Learn how to read complex electrical and hydraulic schematics.
Pressure and flow, current and voltage — we show you how they relate.
Get solid on the fundamentals!

Our lessons alert you to the risks and best practices.
Check the hazards, and concentrate on working safely.

Let's put those pressure gauges, flow meters,
and multimeters in the right hands: yours.
We teach you to be a top troubleshooter.

There are so many different components!
Diodes, resistors, valves, accumulators, pumps...
See how they work, how they fail, and how to fix them.
The days of mindless part-swapping are over.

Load sense? Yep!
Hydrostatic drives? Covered.
Complex valve banks with crazy centers?
We give you guidance and tools for deep understanding.

Our content library keeps getting bigger.
