2000 Ton Scrap Metal Shear: Spec Details That Matter
At flagship scale the specification sheet stops being a summary and becomes a engineering brief. Every row is a decision someone made against a duty, and the buyers who read it properly are checking whether those decisions match their operation. This article walks the Q91-2000 sheet the way a plant engineer reads it: which rows are fixed by the class, which rows are the quotation’s decisions, and which questions to ask about the rows that are not there.
If you are still testing whether the flagship is the right class at all, read the justification guide first — this piece assumes the measurements say flagship and covers how to interrogate the build.
The Fixed Rows: What the Class Guarantees
| Specification | Q91-2000 |
|---|---|
| Rated force | 2000 ton |
| Typical output | 250–300 tons per day |
| Continuous cutting | 170 mm plate |
| Occasional cutting | 210 mm plate |
| Bale capability | Specified capability for baled scrap |
| Duty | Steel mills, largest recycling operations |
These six rows are the class identity, and they are the numbers any quotation must match. The force rating is the hydraulic system’s capability; the output band is what it delivers at three-shift rhythm; the two plate rows are the material boundary — 170 mm continuous as the daily diet, 210 mm as what the week allows; the bale capability row is a specification rather than an assumption, because flagship intake includes baled material as routine; and the duty row names the operation this class exists for.
If a quotation for a 2000-ton machine quotes different boundary rows, the difference is either a configuration choice — which must be stated — or a brochure number, which must be questioned.
The Decision Rows: Where Your Machine Is Specified
Everything that makes the machine yours is decided at quotation, and at this scale the list is longer than at any other class.
Frame and hydraulic duty rating. The build is specified against the shift pattern and material mix you declare. Three shifts on 170 mm plate is a different frame and hydraulic package than two shifts on lighter feed, and the difference is structural — it cannot be retrofitted after the build.
Blade configuration and steel grade. The three heaviest pieces from a normal month decide the blade specification. At flagship force the blade is carrying enormous energy through every cut, and the steel grade, edge geometry and hold-down specification all follow the material list.
Bale capability detail. Not just whether the machine handles baled material, but at what density, what wire type, and how cold. A bale denser than specified is a stalled cycle at this force class, and the boundary belongs in writing.
Cooling capacity. Sustained heavy duty at this scale makes oil temperature a specification item rather than a maintenance note. The cooling package is quoted against the duty, and the operating conversation covers oil condition as an uptime practice.
Power package and starting method. Motor ratings at this class are substantial, and the starting method has to be agreed with your electrician before the build — the supply conversation happens at quotation, not on delivery day.
The Rows That Are Not There
Three things decide your experience with this machine and appear on no specification sheet. Raise all three at quotation:
- The duty declaration. Written down, as run rather than as aspired to. Every build decision follows it, and an optimistic declaration produces a machine that fights the operation in year two.
- The spares and wear-part plan. What ships with the machine, what sits on your shelf before commissioning, and the replacement procedure for each wear part at this duty. At 250 to 300 tons a day this is a staffing commitment, not a line item.
- The line handoff. The stages behind the shear — drop height, buffer, handling — signed off against your site plan during the quotation. Flagship operations run lines, and the line is specified as one plan or rebuilt in month one.
Reading the Quotation as an Engineering Document
The test of a proper flagship quotation is simple: could your electrical and foundation contractors build from it? The sheet that comes back should carry the specification your electrician needs — voltage, frequency, spare kilowatts, starting method — and the foundation data your contractor needs, with anchorage matched to the declared duty. If the quotation cannot answer those two questions, it is a price sheet wearing an engineering costume, and the specification conversation has not happened yet.
Send the material profile, the three heaviest pieces from a normal month, the shift pattern, the power details and the downstream stages. The written quotation comes back within two business days, factory direct, complete with the specification sheet — and with the honest class recommendation, which occasionally is the 1600 below.
The Cooling and Oil Specification
Sustained heavy duty at flagship scale makes oil temperature a specification item rather than a maintenance note. The cooling package is sized against the declared duty — the cycle rate, the ambient temperature at your site, the continuous hours — and the operating conversation covers oil condition as an uptime practice: filters on schedule, temperature checked at start-up and watched through the shift, oil sampled or inspected on the monthly cadence. At 250 to 300 tons a day the pump and seal life that the specification promised is delivered inside that practice or not at all.
This is also why the seal specification conversation happens at quotation. The seal grade, the expected life at your declared duty and the replacement procedure in hours and crane time are all part of the specification document — plant buyers price them before the order because they are pricing downtime, and the factory that answers them precisely is the factory that builds for duty.
Reading the 2000 Against the 1600
The cleanest way to interrogate a flagship quotation is to read it against the class below. The 1600 carries 150 mm continuous and 200 to 240 tons a day; the 2000 carries 170 mm and 250 to 300. The rows that should differ between the two quotations are the frame and hydraulic duty rating, the cooling capacity, the wear-liner strategy and the spares depth — and the rows that should not differ are the certification, the documentation pack and the support structure. A flagship quotation that looks like a 1600 quotation with a bigger number has not had the specification conversation yet.
The Documentation Pack as a Working Document
At flagship scale the documentation pack is not paperwork — it is the reference your maintenance program is built from for a decade. Schematics, foundation drawings, the load test record, the material certificates for frame and blades, and the wear-part schedule with expected life at your declared duty. The pack should be specific enough that a maintenance technician who has never seen the machine can plan a blade change from it, and specific enough that your electrical contractor can verify the supply scope from it without a phone call. If the pack cannot answer those two questions, the specification conversation is not finished — and the quotation is where that gets resolved, not the loading dock.
The Questions Your Engineers Should Ask
The best flagship quotations start with the buyer’s engineering team, not the purchasing department. The questions that produce the best specifications come from the people who will maintain the machine: what is the wear-part replacement procedure in hours and crane time, what is the seal specification at our declared duty, how is the blade gap calibrated and how often, what does the cooling package need in ambient temperature at our site, and what does the load test record actually show. A factory that welcomes those questions is describing a build process; a factory that routes them to a sales script is describing a catalog. Ask them early — the answers shape the specification, and the specification is the purchase.
Buyer FAQ
What makes the flagship build different from the 1600?
Force class and duty basis. The 2000 is specified for 170 mm continuous and 250 to 300 tons a day; the 1600 is the three-shift mill class at 150 mm continuous. The build differences — frame, hydraulics, cooling, wear strategy — all follow from that.
Can the bale capability be configured?
Yes. Send the bale density, wire type and arrival condition your intake produces and the capability is confirmed against it in writing at quotation.
What documentation ships with the machine?
CE and ISO 9001 certification, a factory load test before shipment, and a documentation pack with schematics and foundation drawings for your contractors.
How is the machine tested before shipment?
Every machine undergoes load testing before shipment under our ISO 9001 quality system. At flagship scale the test procedure is part of the documentation pack.
What warranty comes with the machine?
A standard one-year warranty with extended main-frame coverage available per order, spare blades shipped within 48 hours by DHL or FedEx, and on-site commissioning quotable where the site requires it.
