Predictika · Overhead conveyors
An AI sales agent prepares an order for a power-only overhead or inverted chain conveyor: the chain size, the trolleys and their wheel options, the spacing and weight of the carriers, the drive, and the turns, with the trolley count and chain sections it states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the specifications in Daifuku's public technical selection guide and returns a verdict, every reason and the figures it computed.
This validator models one chain conveyor order at a time, based on the public Daifuku Chain Conveyors Technical Selection Guide for Conveyor Components (power-only overhead and inverted conveyors), not just the scenarios shown below.
Any order for these Daifuku conveyors that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the guide lists none, so this page shows no price build-up), hand pushed trolleys, vertical curves and track, takeups, other Daifuku conveyor families, and system engineering such as computing the chain pull from the layout, which this validator takes as a figure the order provides.

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 |
|---|---|---|
| Each trolley belongs to one chain size and has its own spacing range and rating | Only with workarounds The guide lists seven trolleys, each for one chain with its own minimum and maximum centers and load rating. A rules-based CPQ needs a compatibility table or a rule per trolley, kept in step with the guide. | The trolley is looked up on every call and the chain, the spacing and the load are compared with it together. |
| Loads that double with a load bar, but only on some trolleys | Only with care The rating depends on the trolley and on whether a load bar is used, and the inverted trolleys have none; the check has to combine both. | The rating for the chosen trolley and load bar choice is computed and compared with the carrier weight on every call. |
| Wheel options that exist only in certain combinations (28 listed variants) | Only with workarounds Inner cap, seal and guard are three yes-or-no choices whose valid combinations differ by trolley. A product rule has to list every allowed combination for every trolley. | The combination is matched to the listed half-trolley variants, and its part number comes back with the answer. |
| Drives by chain size, capacity and speed, with a speed range | Only with workarounds Which capacities and speeds are offered depends on the chain, and the usable speed range depends on the drive. That is a table plus arithmetic across several fields. | The drive row is matched, then the chain pull and the speed are compared with it in the same call. |
| Trolley count and chain sections the order states | Only with care The stated figures come from the chain length and the centers, so a rule has to recompute them and compare. | The stated counts are fields in the request, compared with the computed ones on every call. |
| 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 person 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 selected trolley is listed in the guide for a different chain size than the chain on the order. |
| 2 | Trolley centers of 6 inches are below the 8 inch minimum for this trolley. |
| 3 | Trolley centers of 36 inches are above the 32 inch maximum for this trolley. |
| 4 | Each carrier weighs 450 lb; the rating for this trolley setup is 400 lb. |
| 5 | Each carrier weighs 850 lb; the rating for this trolley setup is 800 lb. |
| 6 | The guide lists no load bar capacity for this inverted trolley. |
| 7 | Each carrier weighs 250 lb; the rating for this trolley setup is 200 lb. |
| 8 | Each carrier weighs 1300 lb; the rating for this trolley setup is 1200 lb. |
| 9 | The carriers need 400 loaded trolleys; the chain length and trolley centers give 300 trolleys in total. |
| 10 | The order has 0 carriers; at least 1 is needed. |
| 11 | The guide lists no half trolley with this combination of inner cap, triple labyrinth seal and Red Seal Guard for the selected trolley. |
| 12 | The operating temperature of 500 degrees Fahrenheit is above the 450 degree rating of the standard full complement trolley wheels. |
| 13 | The guide lists no such drive for this chain: UniFrame drives at 15, 45 and 60 fpm with 1000 or 2000 lb capacity for X-348, 2000 or 3000 lb for X-458, and drive sizes B and C for X-678. |
| 14 | The design chain pull is 3200 lb; the selected drive is rated for 3000 lb. |
| 15 | The design chain pull is 6500 lb; the selected drive is rated for 6400 lb. |
| 16 | The design chain pull is 10,500 lb; the selected drive is rated for 10,000 lb. |
| 17 | The conveyor speed of 50 fpm is outside the range of the selected UniFrame drive, which runs from one third of its 45 fpm nominal speed up to that speed. |
| 18 | The conveyor speed of 14 fpm is outside the range of the selected UniFrame drive, which runs from one third of its 45 fpm nominal speed up to that speed. |
| 19 | The conveyor speed of 130 fpm is outside the 1 to 120 fpm range of the drive selection chart. |
| 20 | The traction wheel turn is 24 inches in diameter; the guide recommends at least 30 inches for this chain and trolley spacing. |
