What is VIS-Check?

It is a diagnostic machine that checks the brakes, steering and suspension of heavy trucks, then produces a Safety and Efficiency Report to guide maintenance activities. 

Why focus on undercarriage diagnostics?

The undercarriage of a vehicle is where the weight of a vehicle meets the road. 

Safety, fuel economy and tire life are all compromised if undercarriage components are not in top working condition.  

Why use a machine to perform undercarriage diagnostics?

 The VIS-Check machine makes performing undercarriage diagnostics:

·         Safer by reducing manual labor

·         Faster by automating brake testing

·         Traceable by producing an inspection report

·         More accurate by improving inspection methods

How does it work?

VIS-Check is comprised of two diagnostic devices; a performance based brake tester (PBBT) and a dynamic road simulator.

The PBBT measures the effectiveness of vehicle brakes by measuring the brake force produced by  the truck through a complete braking cycle (apply, hold and release).

The road simulator helps technicians inspect the steering and suspension of a truck by dynamically loading these linkages consistent harsh over-the-road operation. 

What type of report does the brake test produce?

The brake test produces a report that indicates the following for each wheel end:

·         weight

·         peak brake force

·         compliance to DOT requirements

·         left to right brake force balance

·         rolling resistance with no braking

From this information the following can be identified:

·         glazed or contaminated linings

·         incorrect brake adjustment

·         air distribution problems

·         faulty slack adjusters

·         drum out of round

·         weak brake force 

What type of report does the road simulator produce?

The road simulator produces an inspection report that identifies otherwise undetectable steering and suspension issues.  These might include:

·         worn tire rod ends and king pins

·         spring pin, shackle & hanger issues

·         loose cab or exhaust mounts

·         defective shock absorbers

·         loose wheel bearings

·         broken springs

·         worn bushings

For each undercarriage Condition identified by VIS-Check:

·         an operating efficiency down-the-road Effect is provided

·         a recommended maintenance Solution is provided 

Is VIS-Check difficult to operate?

Not at all.  Technicians require less than an hour of training to operate VIS-Check 

What types of businesses operate VIS-Check?

Repair Shops     – to improve the quality of service they provide.

Fleets               – to improve the safety and efficiency of their vehicles.

Inspectors         – to ensure vehicle compliance with DOT regulations

TESTIMONIAL:

Heavy Duty Scoops the Automotive World

By Dave Skrobot

It’s a diagnostic device called VIS-Check.  One part performance based brake tester (PBBT) and one part dynamic road simulator.  It’s the most impressive diagnostic combo I have ever seen.  The PBBT produces a definitive report on the health of a vehicle’s brakes, including a PASS or FAIL rating to DOT performance requirements.  Then, the dynamic road simulator helps technicians identify undercarriage abnormalities related to steering, suspension and drive train.  Abnormalities that would otherwise go undetected.
