Predictika · Wheeled excavator configurations
An AI sales agent prepares a configuration for a 7MWR, 9MWR or 11MWR wheeled excavator: the tires, the steering options, the boom, a hydraulic thumb, the work-tool and a tiltrotator, with the weight, width and turning radius it states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published Mecalac leaflets and returns a verdict, every reason and the leaflet figures it compared against.
This validator models option lists, availability statements and figures printed in the Mecalac leaflets MK360 (7MWR, 9MWR, 11MWR) and MK399 (Tiltrotators for excavators), not just the scenarios shown below.
Any configuration of these three models that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Mecalac publishes no price list for these machines, so there is no price build-up); the 15MWR and the other Mecalac ranges; the weight of a tiltrotator unit (the two leaflets print different MR40 weights, so the weight check is not run when a tiltrotator is selected); speed options, counterweight, cab and air conditioning options, and tools whose leaflet table does not name a model (pallet fork, handling plate, ripper tooth, narrow bucket, 4x1 bucket and grapple bucket). The leaflet says standard and optional equipment may vary by market and to consult a Mecalac dealer.

What this means
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.
| What the validator caught | Typical rules-based CPQ | Predictika |
|---|---|---|
| Tools and tiltrotators that depend on the model | Only with care Hammer sizes, the largest digging bucket and the tiltrotator size differ between the 7MWR, 9MWR and 11MWR, and each grading bucket is dedicated to one tiltrotator, so every tool needs its own model list and a pairing rule. | The model sets the tool and tiltrotator lists once, and the pairing is checked with everything else on every call. |
| Weight, width and turning radius that depend on the choices | Only with workarounds The weight adds up from a model base, tires, front stabilisers, the tool and a thumb; the width depends on model and tires; the turning radius on model and steering. That means lookup tables and summary variables that have to be kept in step with the leaflet. | The figures are derived from the same choices that drive the rules, in the same pass. |
| A stated figure checked against the computed one | Only with workarounds The agent states a weight, a width and a turning radius, and each has to be compared with a computed value that changes with the configuration; a mismatch has to stop the order. | The stated figure is a field in the order, and the validator blocks when it differs from the leaflet figure. |
| Every problem returned in one answer | Only with workarounds Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next. | All findings come back together, whatever order the choices arrived in. |
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the order; approval findings need a person to sign off; everything else is computed.
| 1 | The tire choice Alliance 600/40 R22.5 is not in the tire list of the 9MWR in the leaflet. |
| 2 | The tire choice Alliance 500/45 R20 is not in the tire list of the 11MWR in the leaflet. |
| 3 | The order states a machine weight of 8,000 kg; the leaflet weights for this configuration add up to 8,060 kg. |
| 4 | The order states a machine width of 2,025 mm; the leaflet lists 2,120 mm with this tire on the 7MWR. |
| 5 | The order states an outside turning radius of 3,560 mm; the leaflet lists 6,100 mm for the 9MWR with this steering. |
| 6 | Steering direction inversion is listed for 4 steering wheels only; the order has 2 steered wheels. |
| 7 | Mudguards are listed for 4 steering wheels only; the order has 2 steered wheels. |
| 8 | Front stabilisers and blade are listed as not available for the 7MWR. |
| 9 | The gearbox with automatic shift is listed as not available for the 7MWR. |
| 10 | The 2-piece boom with offset is listed for the 7MWR only; the 9MWR is listed with the Mecalac versatile boom. |
| 11 | The work-tool 1,200 mm digging bucket is not listed for the 9MWR in the leaflet. |
| 12 | The work-tool MB30 hydraulic hammer is not listed for the 9MWR in the leaflet. |
| 13 | The work-tool MB50 hydraulic hammer is not listed for the 7MWR in the leaflet. |
| 14 | The handling jib is to be used with 4 safety valves (boom, adjustable boom, dipperstick and bucket); the order has the standard 3. |
| 15 | The hydraulic thumb is available with the 2-piece boom with offset only. |
| 16 | The hydraulic thumb is listed for the 7MWR only; the 11MWR is not listed with one. |
| 17 | The tiltrotator MR40 is not listed for the 9MWR; the leaflet lists the MR40 for the 7MWR and the MR50 for the 9MWR and 11MWR. |
| 18 | The tiltrotator MR50 is not listed for the 7MWR; the leaflet lists the MR40 for the 7MWR and the MR50 for the 9MWR and 11MWR. |
| 19 | The work-tool 1,300 mm grading bucket is a dedicated tiltrotator grading bucket (1,200 mm for the MR40; 1,300 mm and 1,500 mm for the MR50); the order has no tiltrotator. |
| 20 | The work-tool 1,500 mm grading bucket is not listed for the 7MWR in the leaflet. |
| 21 | The work-tool 1,500 mm grading bucket is a dedicated tiltrotator grading bucket (1,200 mm for the MR40; 1,300 mm and 1,500 mm for the MR50); the order has MR40. |
| 22 | The work-tool 1,200 mm grading bucket is a dedicated tiltrotator grading bucket (1,200 mm for the MR40; 1,300 mm and 1,500 mm for the MR50); the order has MR50. |
| 23 | The tire choice Alliance 600/40 R22.5 is not in the tire list of the 7MWR in the leaflet. |
