Predictika · Rough terrain crane proposals
An AI sales agent prepares a proposal for a Tadano GR-300N rough terrain crane: outrigger setting, boom length, working radius, load, hook and part lines. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the rated-load chart and the winch notes from the public specification sheet and returns a verdict, every reason and the figures it computed.
This validator models main-boom lifts of the Tadano GR-300N rough terrain crane only, not just the scenarios shown below. It does not cover any other Tadano crane.
Any main-boom lift of the GR-300N with the outriggers set that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Tadano publishes no price list, so this validator produces no price build-up or line-item quote), jib and single-top lifts, lifts without outriggers, the over-front and over-rear ranges, the swing-angle limits for narrower outrigger widths, ground conditions, the Working Radius - Lifting Height chart, and every other Tadano model.

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 rated load that depends on outrigger width, boom length and radius | Only with workarounds The rated load is a three-way table (five outrigger settings, seven boom lengths, up to 29 radii). A rules-based CPQ needs that table loaded as lookup data and a query for every line, and every blank cell in the chart has to be handled as "not allowed". | The chart is part of the model; the rated load is computed on every call from the three choices, and a missing chart entry is reported as outside the reach or minimum radius of the boom. |
| Load plus hook weight against the rated load | Only with care The check is simple arithmetic, but the hook weight has to be added from the hook choice on another line before comparing, and the comparison has to be written for each case. | The hook weight, the gross load, the limit and the margin are computed together on every call. |
| Part lines against the 3.75 t and 4.0 t line limits | Only with care The limit depends on which winch the hook is on and has to be multiplied by the number of part lines; a rule can do it, but it is one more rule to write and keep in step. | The line limit is computed from the hook and the part lines, and the boundary (exactly at the limit is allowed, one kilogram over is blocked) is tested. |
| Free-fall only on the free-fall winch, and only under one fifth of the rated load when loaded | Only with workarounds The second limit depends on the rated load, which itself comes from the chart, so the rule needs the lookup result before it can run. | The chart lookup and the free-fall limit are in one model, so the free-fall rule always sees the current rated load. |
| A stated rated load that must match the chart | Only with care The stated figure is a free-entry field; a rule can compare it with a computed one, but someone has to write and maintain the comparison. | The stated figure travels with the proposal and is compared with the computed figure on every call. |
| Every problem returned in one answer | Only with workarounds Rules tend to fire as the proposal 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 load plus hook weighs 9,960 kg, but the rated total load for this boom length, radius and outrigger setting is 9,900 kg. |
| 2 | The rated-load chart has no entry for this boom length at the planned working radius with these outriggers; the radius is beyond the reach of the boom or inside its minimum radius. |
| 3 | The load plus hook weighs 8,260 kg, but the rated total load for this boom length, radius and outrigger setting is 5,950 kg. |
| 4 | The load plus hook weighs 10,760 kg, but the rated total load for this boom length, radius and outrigger setting is 10,700 kg. |
| 5 | 9,260 kg with 2 part line(s) is above the 7,500 kg the lines can take; the load per line must not exceed 3.75 t on the main winch or 4.0 t on the auxiliary winch. |
| 6 | 3,751 kg with 1 part line(s) is above the 3,750 kg the lines can take; the load per line must not exceed 3.75 t on the main winch or 4.0 t on the auxiliary winch. |
| 7 | 4,001 kg with 1 part line(s) is above the 4,000 kg the lines can take; the load per line must not exceed 3.75 t on the main winch or 4.0 t on the auxiliary winch. |
| 8 | Free-fall lowering is available only on cranes fitted with winches with the free-fall device; this crane has the winch without it. |
| 9 | A hoisted load may be lowered by free-fall only if it is kept below one fifth of the total rated load; the load plus hook is 1,980 kg and the rated load is 9,900 kg. |
| 10 | A hoisted load may be lowered by free-fall only if it is kept below one fifth of the total rated load; the load plus hook is 9,260 kg and the rated load is 9,900 kg. |
| 11 | The proposal states a rated total load of 10,500 kg, but the rated load for this boom length, radius and outrigger setting is 9,900 kg. |
| 12 | The proposal states a rated total load of 9,000 kg, but the rated load for this boom length, radius and outrigger setting is 9,900 kg. |
| 13 | The load plus hook weighs 5,260 kg, but the rated total load for this boom length, radius and outrigger setting is 3,450 kg. |
| 14 | 5,260 kg with 1 part line(s) is above the 3,750 kg the lines can take; the load per line must not exceed 3.75 t on the main winch or 4.0 t on the auxiliary winch. |
| 15 | The proposal states a rated total load of 9,000 kg, but the rated load for this boom length, radius and outrigger setting is 3,450 kg. |
