Predictika · Commercial vehicle components
An AI sales agent prepares an order for a HOLLAND fifth wheel with its kingpin: the model and overall height, the lock size, the weights of the tractor and the semi-trailer, and the D-value and imposed load it quotes. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the manufacturer's published catalogue and returns a verdict, every reason and the figures it looked up.
This validator models orders for the HOLLAND fifth wheel range (11 models), the four SAF kingpins, the four sliders and the RECOSS, RECOLUBE and grease cartridge options, as listed in the SAF-HOLLAND Fifth Wheels and Kingpins catalogue (Rev I, 03/2026), not just the scenarios shown below.
Any HOLLAND fifth wheel order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (SAF-HOLLAND publishes no list prices, so this validator produces no price build-up), other SAF-HOLLAND product lines, fitting and installation, and anything beyond the catalogue tables read. Where the catalogue gives no D-value for a model, the validator asks a person to confirm instead of guessing.

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 |
|---|---|---|
| A D-value that has to be calculated from the weights | Only with workarounds The required D-value comes from a formula over the tractor, trailer and vertical weights, and it must be compared with a different rating for each fifth wheel, kingpin and slider. | The formula is evaluated on every call and compared with each rating and with the figure the rep typed in. |
| Ratings that depend on the lock size | Only with care Imposed load and D-value change with the 2 or 3.5 inch lock, and only some models offer the larger lock. | The rating for the selected lock size is looked up on every call, and an unavailable lock is reported as a choice error. |
| Kingpin, skid plate and height lists per model | Only with workarounds Each kingpin has its own list of skid-plate thicknesses and each fifth wheel its own heights, so the lists are maintained in many places. | Every list is part of the model and is checked together with the rest of the order. |
| Terminal tractor and special-model rules | Only with care Speed limits, combination weight limits, the secondary lock and the road approval apply to a few models only. | Each rule applies to its model on every call and is explained in plain words. |
| 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 quote; approval findings need a person to sign off; everything else is computed.
| 1 | The vertical load on the fifth wheel is 8 t, but this fifth wheel is rated for an imposed load of 6 t. |
| 2 | This tractor and semi-trailer combination needs a D-value of 70.15 kN, but the fifth wheel is rated 49 kN. |
| 3 | The vertical load on the fifth wheel is 20.5 t, but this fifth wheel is rated for an imposed load of 20 t. |
| 4 | This fifth wheel is catalogued only with a 2 inch lock, but the quote asks for a 3.5 inch lock. |
| 5 | The kingpin size does not match the fifth wheel lock size; a 2 inch lock takes a 2 inch kingpin and a 3.5 inch lock a 3.5 inch kingpin. |
| 6 | The semi-trailer skid-plate thickness of 16 mm is not offered for this SAF kingpin. |
| 7 | This tractor and semi-trailer combination needs a D-value of 178.93 kN, but the SAF kingpin is rated 165 kN. |
| 8 | The vertical load on the fifth wheel is 24 t, but this fifth wheel is rated for an imposed load of 23 t. |
| 9 | The semi-trailer skid-plate thickness of 12 mm is not offered for this SAF kingpin. |
| 10 | The semi-trailer skid-plate thickness of 6 mm is not offered for this SAF kingpin. |
| 11 | The overall height of 160 mm is not listed for this fifth wheel. |
| 12 | The vertical load on the fifth wheel is 23.5 t, but this fifth wheel is rated for an imposed load of 23 t. |
| 13 | The overall height of 225 mm is not listed for this fifth wheel. |
| 14 | The overall height of 200 mm is not listed for this fifth wheel. |
| 15 | The frame-integrated FW3214-W is catalogued only for Mercedes-Benz Actros and Antos tractors with a 3,700 mm wheelbase and a 600 mm coupling point. |
| 16 | This tractor and semi-trailer combination needs a D-value of 166.77 kN, but the fifth wheel is rated 152 kN. |
| 17 | This tractor and semi-trailer combination needs a D-value of 166.77 kN, but the SAF kingpin is rated 165 kN. |
| 18 | This tractor and semi-trailer combination needs a D-value of 166.48 kN, but the SAF kingpin is rated 165 kN. |
| 19 | This tractor and semi-trailer combination needs a D-value of 182.59 kN, but the fifth wheel is rated 152 kN. |
| 20 | This tractor and semi-trailer combination needs a D-value of 182.59 kN, but the SAF kingpin is rated 165 kN. |
| 21 | The quote states a required D-value of 95 kN, but the combination works out to 82.55 kN. |
| 22 | The quote states an imposed load rating of 23 t, but this fifth wheel is rated 20 t. |
| 23 | The loaded semi-trailer weighs 10 t, which is less than the 12 t it puts on the fifth wheel. |
| 24 | The vertical load is 23 t, but the slider is rated for an imposed load of 22 t. |
| 25 | This tractor and semi-trailer combination needs a D-value of 143.31 kN, but the slider is rated 135 kN. |
| 26 | The SK-V 36 slider is for heavy-duty fifth wheels of 150 or 190 mm overall height; the quote has 185 mm. |
| 27 | The ILS slider is listed in the catalogue for the HOLLAND FW3510; a person should confirm it fits this fifth wheel. |
| 28 | The catalogue lists RECOSS as available ex works only for certain tractor makes; a person should confirm it for this tractor. |
| 29 | The RECOSS safety sensor system is offered only for the SK-S 36.20 range. |
| 30 | The catalogue lists RECOLUBE as available ex works at MAN vehicles; a person should confirm it for this tractor. |
| 31 | The RECOLUBE pump is compatible only with vehicles built from 1 April 2,017; this tractor was built in 201,612. |
| 32 | The RECOLUBE lubrication pump is offered only for the SK-S 36.20, SK-S 36.20 H and SK-HD 38.36. |
| 33 | The automatic grease cartridge is offered only for the FW3214-W and the SK-S 36.20 W. |
| 34 | The manual secondary lock option is offered only on the FW3510-TR terminal tractor fifth wheel. |
| 35 | The FW3510-TR needs the manual secondary lock for use on the public highway, and the quote has none. |
| 36 | This terminal tractor fifth wheel is limited to 35 km/h; the quote has 36 km/h. |
| 37 | The gross combination weight is 104 t, but this fifth wheel is limited to 100 t. |
| 38 | The FW0E70-T has no type approval to ECE R 55, so it is not for use on public roads. |
| 39 | The catalogue gives no D-value for this fifth wheel, so the D-value check could not be made; a person should confirm it with SAF-HOLLAND. |
| 40 | The gross combination weight is 124 t, but this fifth wheel is limited to 120 t. |
