TradeRig is a browser-based simulation platform for skilled trades. Build a real system, inject a fault, and trace it with working virtual tools — before you ever touch live equipment. Live now with Heavy Equipment Electrical, with an Electrician (Commercial & Industrial) lab in preview and more — Hydraulics, Air Brake, HVAC, Measuring Tools — arriving as each goes live. Electrical is live now, free during launch.
Diagnostic skill comes from reps, but bay time is scarce, training rigs cost a fortune, and one wrong probe on a live harness fries parts. Most apprentices get a handful of attempts before the job depends on it.
Apprentices need to run faults again and again. A shared bay can't give everyone the time.
Training machines are expensive and tied up. Equipment access becomes the bottleneck.
One wrong probe or a backwards connection on a live harness fries components and burns the budget.
Instructors can't see who actually understands diagnosis until it shows up on the job.
The same loop a real tech runs, on a rig that never runs out and never costs you a part.
Drag components onto the canvas and wire up a 12V/24V circuit.
Inject a fault (open, short, bad ground, blown fuse) or let a scenario surprise you.
Probe with a virtual multimeter and test light.
Follow the evidence to the root cause.
Make the repair, run it again, confirm it works.
A full heavy-equipment electrical lab in your browser: real 12V/24V circuit behaviour, real faults, real test tools. Build a circuit, inject a fault, and trace it to ground.
Pick your trade and TradeRig surfaces its labs — one deep, comprehensive lab per system, not a maze of modules. Plus shared Core Labs every trade can open, with content tailored to your equipment.
Shared across every trade — the same lab, with scenarios filtered to your trade's tools and tasks.
Voltage, resistance, continuity, current, pressure, temperature, torque — the right instruments and reps for your trade.
Lockout / tagout, PPE, and hazard recognition — foundational reps every trade shares.
A full toolkit around the canvas: the same gear and feedback a tech leans on, in the browser.
Batteries, fuses, relays, loads, and more.
Open circuits, shorts, bad grounds, blown fuses.
Probe voltage, continuity, and current, and blow the fuse if you measure amps wrong, just like the real thing.
Live hints and guidance as you work.
Clear steps to follow, plus open challenges.
Scores, attempts, and skill insights.
Assign exercises and review results.
Every run saved and reviewable.
HET, diesel, heavy-duty, and automotive apprentices. Get unlimited reps on real circuit behaviour and build diagnostic confidence before you ever touch a live harness.
Assign diagnostic exercises, see who's mastered each fault, and spend class time where it counts.
Level up the crew's diagnostic confidence and cut the downtime that comes from guesswork.
Run your class on the same simulator your students use. Create classes by trade, assign only the labs your students need, and track progress by system, fault type, and attempt history. Students join with a class code, no setup for them. Pilots are open for instructors and schools; get in touch and we'll set up your class.

A simulation platform for skilled trades. You build a real system, inject a fault, and diagnose it with working virtual tools, building real skill before you touch live equipment. It's live now with Heavy Equipment Electrical and expands into trade-specific labs — Electrician (Commercial & Industrial), Hydraulics, HVAC, Air Brake, Measuring Tools — as each goes live.
The live lab today is Heavy Equipment Electrical (DC diagnosis). A separate Electrician — Commercial & Industrial lab is in preview — AC / line-voltage, 3-phase, motor control, panels and branch circuits. It's a distinct training path from the heavy-equipment DC lab, on the same platform.
Electrical is the first live system. Hydraulic, Air Brake, HVAC, and Measuring Tools are coming on the same canvas, with more to follow.
Electrical, live today: 12V/24V circuits, relays, grounds, loads, fault injection, a virtual multimeter, and Build Coach guidance.
Electrical is free during launch, no credit card. Paid plans come later; early users get in free.
No. Runs in any modern browser. A desktop or a tablet in landscape works best, the lab needs room to place components, wire terminals, and read test points.
Yes. Instructors assign exercises and see scores, attempts, and weak areas per student. Instructor access is set up through a pilot, get in touch.
They're coming soon, built into the same platform you'd start on today. We'll add them as they're ready, and we'll never claim a system is live before it is.
