Reads the job context
Keep the machine, symptom, operating condition, and prior readings together across turns.
Prototype validation for crane and hoist diagnostics
LiftMate guides qualified technicians one test at a time.
LiftMate is an AI troubleshooting assistant built for overhead crane and hoist technicians. It helps guide qualified technicians through electrical troubleshooting one step at a time using symptoms, meter readings, equipment context, and structured fault-isolation logic.
Currently in prototype validation for controlled testing, internal review, and authorized pilot discussion.
Overhead cranes
Bridge, trolley, hoist, brake, limits, drive, and control power faults.
Stepwise logic
One reading at a time, with branch decisions based on the technician response.
Evidence aware
Reported readings, observations, and approved job context stay tied to the fault path.
What it does
A practical assistant for messy electrical troubleshooting.
LiftMate is tuned for the problems that slow crane service calls down: dead controls, one-direction travel, brake release failures, pendant faults, drive input issues, and control-power problems that need step-by-step isolation.
Chooses the next probe
Ask for the measurement that separates likely branches instead of guessing a part.
Tracks evidence
Final calls are grounded in readings the technician actually reported.
Tests regressions
Saved scenarios compare behavior across versions to surface missed branches and drift.
Testing & validation
Internal regression testing is part of the product.
In the v4.1 reviewed first-response regression set, LiftMate passed 64 of 75 structured scenarios and averaged 6.25 out of 7. The result is useful prototype evidence, not a field-performance claim.
Workflow
From symptom to supported fault isolation.
-
1
Describe the failure
Start with the machine, command, symptom, voltage class, and what still works.
-
2
Follow one test
LiftMate asks for the next reading or observation that best separates the fault path.
-
3
Report readings
Answer each requested test so the assistant can narrow the fault path.
-
4
Review the evidence
Use the test trail to support the next action while following site procedures.
Interactive comparison
Put a fixed decision tree to the test.
Choose a common symptom and follow a simple, illustrative tree. Then load the same symptom into the live LiftMate demo. Watch what happens when a reading is missing or the situation needs more context.
Fixed path
Decision tree
Follow the preset yes/no questions. This is an example tree, not a manufacturer's procedure.
Live prototype
LiftMate
Start with the same symptom. LiftMate can ask for one next observation or reading and use your reply on the following turn.
Same starting symptom
What to compare in the live demo
- Does it identify the next useful test?
- Can you report “not checked” or add relevant context?
- Does the next step reflect the reading you gave?
The live response is generated when you send the prompt; this panel does not predict its answer.
Illustrative comparison only. A decision tree can be effective when its branches cover the case; this exercise shows where a fixed example needs an added branch. It is not a measured performance claim or a field diagnostic procedure. Qualified technicians must follow site safety procedures.
