Start with the work, not the camera count
A wheel alignment machine measures wheel geometry so a technician can compare it with the applicable vehicle specifications. Choosing one means matching the complete measurement system to the vehicles, lift, available space and people doing the work. Camera count alone is not a specification for accuracy, throughput or vehicle coverage.
First review wheel alignment fundamentals. Toe, camber, caster and thrust angle answer different questions; a quick camber-and-toe check is not the same service as a complete alignment with a caster sweep, adjustment and verification.
Camera-based systems: architecture and configuration
Imaging systems observe targets attached to the wheels and use the measured target positions to calculate wheel geometry. A two-camera or four-camera description identifies camera count, not the full optical design. Ask which targets each camera observes, how reference relationships are maintained, and how camera position changes with lift height.
Read 2-camera vs 4-camera wheel alignment systems before comparing demonstrations. A system marketed as 3D still needs the correct installation envelope, unobstructed targets and the prescribed measurement procedure.
Fixed systems place the measuring equipment in a defined location. A mobile configuration can make sense when several suitable bays share equipment, but a cabinet on wheels does not necessarily mean the cameras and reference system are mobile. Check precisely what moves, what must remain fixed and what setup is required after relocation.
Define vehicle and database coverage
List the passenger cars, SUVs, vans and light trucks the shop actually services. Record wheel sizes, wheelbase and track-width extremes rather than relying on a general vehicle-class label. Confirm that the lift, clamps, targets and measurement envelope all cover the same intended vehicles.
Ask for a demonstration using the regional vehicle database you will receive. Check model year, trim, suspension variants, ride-height conditions and loading instructions. A database-region label does not prove that every local vehicle is included. Confirm update arrangements, licence terms and what happens when a specification is missing.
Measure the bay and check the lift
Document usable bay width and length, camera-to-vehicle distance, ceiling clearance, lift position, approach path and technician access. Consider open doors, adjacent lifts, storage and service tools that could obstruct target visibility. Check the arrangement at every measuring and adjustment height, not only with the lift lowered.
Provide the supplier with the lift model and installation drawings. Confirm runway length, turn plates, rear slip plates, levelness at the measuring position and the movement needed for compensation. Read planning an alignment bay before committing to floor drilling or a particular workstation location.
Evaluate a complete technician workflow
Use your expected alignments per day and staffing pattern to plan a demonstration. Time the complete job: positioning the vehicle, fitting targets, selecting specifications, compensating runout, measuring caster, adjusting, verifying and producing a report. A quoted measurement time should not be treated as the total service time.
Have both experienced and less experienced technicians try the prompts. Check target-status feedback, screen visibility from adjustment points and recovery after an interrupted procedure. Inspect report clarity and customer-record handling. Remote controls or connected-lift functions should be evaluated only if included and compatible with the proposed configuration.
Study runout compensation and caster sweep technique so the demonstration tests repeatable measurement rather than just interface speed.
Targets, clamps and calibration
Compare target size, wheel or tire attachment, clamp range, wheel-finish protection, storage and handling. Ask how target damage, a dropped clamp or hardware replacement is detected and addressed. Confirm accessory requirements for unusual wheels rather than assuming an adaptor is included.
Request the calibration procedure and service plan for the exact model. Find out which checks the shop can perform, which require service equipment, and what events trigger recalibration. Do not infer calibration intervals or maintenance-free operation from camera count or passive target design.
Software, installation and ongoing support
Review the installed software package separately from the hardware. Confirm measurement routines, regional database, reports, customer records and any optional functions in writing. For TreadPlus systems, SureAlign provides the alignment workflow; available functions depend on hardware, software version, licensed modules and region.
Before ordering, agree who handles delivery, installation, electrical and network preparation, calibration and technician training. Ask who provides local service, what remote support needs, how replacement parts are obtained and which warranty costs are excluded. Include installation, accessories, updates and downtime planning in the ownership comparison.
Questions to answer before requesting a quotation
- What vehicles will the shop align, including its widest and longest regular vehicles?
- How many alignments are performed per day, and by how many technicians?
- Is there a dedicated alignment bay, or must equipment move between bays?
- What lift model, turn plates and slip plates will be used?
- How much usable space is available at every operating height?
- Which regional vehicle database and update arrangement are required?
- Which target and clamp options suit the wheel and tire mix?
- Who will install, calibrate, train and support the equipment?
- Which software functions and accessories are included in the written quotation?
