200 Ton Scrap Metal Shear Specs: How to Read the Sheet
A specification sheet is a sales document wearing technical clothing. Every number on it is true, but no number on it tells you what the machine will do on your feed, with your excavator, on your power supply, in your climate. Reading a gantry shear datasheet properly means knowing which rows decide your operation, which rows are configuration choices you are about to make, and which rows are marketing. This article walks the Q91-200 sheet row by row and tells you what each one actually means for a yard buying its first continuous shear.
If you have not read the material-boundary side of this machine yet, start with our full 200-ton buyer’s guide — this piece assumes you know what the machine is for and focuses on how to interrogate the numbers.
Row One: Shearing Force, and What 200 Ton Does Not Mean
The Q91-200 is rated at 200 ton of shearing force. That is the headline number and the least informative one on the sheet. Force is not a promise about a specific piece of steel; it is the rating of the hydraulic system pushing the blade down. What you can actually cut is decided by force working through blade geometry, against the material’s cross-section and hardness.
The practical translation for this class: routine work is rebar, light and medium sections, angle and profile steel, light pipe, and plate under 30 mm. Occasional work reaches toward heavier sections around 60 mm. Anything beyond that is the next class’s job. When a supplier quotes you “200 ton” against a material list that includes continuous HMS, they are quoting the badge, not the boundary — and our buying guide explains how to hold any factory to the boundary conversation.
The Configuration Rows: Where Your Machine Is Actually Decided
Four rows on the Q91-200 sheet are not specifications in the usual sense — they are decisions, and they are made at quotation, in conversation with our engineers, against your site and your feed.
| Row | Options | How to choose |
|---|---|---|
| Blade length | 1,100 mm or 1,200 mm | Shorter stock and compact yards take 1,100 mm. Intake with longer beams and bundled sections takes 1,200 mm. |
| Motor power | 22 / 27 / 30 / 2×22 kW | Generator or diesel sites usually take the lower kW; grid-connected yards with throughput ambitions move up. |
| Feeding tank length | 4 m / 4.5 m / 5 m | Tight footprint takes 4 m. Longer tanks mean fewer excavator cycles and smoother continuous cutting. |
| Power source | Electric / generator / diesel | Match to your site: grid supply, off-grid operation, or a station that moves between sites. |
Notice what is not on that list: nothing about cutting capacity changes with these choices. The force rating is the force rating. What changes is how smoothly the machine runs in your yard — how many excavator cycles per shift, whether the motor starts cleanly on your supply, whether the machine fits through the door with the tank you chose. A datasheet that presents these as fixed is a datasheet from a factory selling one-size machines. Custom configuration is standard practice at HUAXIN, not an exception.
The Performance Rows: Cycle Time and Daily Capacity
Two rows describe how fast the machine works, and they interact in a way buyers routinely misread.
Cycle time: 20 to 30 seconds per cut. That is loading to indexed-and-ready: material pushed into position, clamped by the hold-down cylinder, blade descent and cut, retraction, release, next piece indexed. The band exists because material changes the cycle — a tight bundle of rebar cuts differently from a flattened car shell. When a datasheet quotes a single cycle number with no band, ask what material it was measured on.
Daily capacity: 20 to 40 tons per day. This is the row that decides whether the machine fits your operation, and it is deliberately a range. Where you land inside it depends on material type, loading efficiency, cut length, operator workflow and how many hours the machine actually runs. Light, well-graded scrap at the top of the excavator’s reach sits near 40; bulky, mixed intake near 20. No factory can honestly put a single number here, and one that does is guessing at your feed.
The interaction matters: cycle time sets the ceiling, daily capacity is where the ceiling meets your material and your crew. A yard that runs one shift with a shared excavator will land at the bottom of the band on the same machine that lands at the top for a yard with a dedicated grapple and a second shift. Our engineers size the configuration around your actual material profile, not a brochure average — and that sizing conversation happens before the order, not after.
The Blade Row: The Most Important Line Nobody Reads
Blade material is a single row on the sheet and the longest-running cost on the machine. The Q91-200 ships with H13 or M6V tool steel at 56 to 62 HRC, hardened for abrasive ferrous scrap, in a four-sided reversible cutting head. Each blade can be used four times before replacement, and one complete blade set processes approximately 5,000 to 10,000 tons of scrap depending on material, cutting thickness and maintenance discipline.
Three questions that row should make you ask:
- Which steel for my feed? H13 and M6V are both credible choices; the recommendation follows your material mix, and abrasive or contaminated feed earns a specific conversation at quotation.
- How fast do spares arrive? Replacement blades leave our warehouse inside 48 hours by DHL or FedEx. For a small yard, that is the difference between a planned swap and a lost week.
- What is the regrind story? Four-sided reversible heads get reground and reused; the blade seat condition and the gap setting after every change decide whether the next set lasts as long as the last.
Buyers who treat blades as a precision consumable and budget for them see blade life close to the published figures. Buyers who treat them as an afterthought get half of it, on the same machine.
The Compliance Rows: What CE and ISO Actually Certify
The Q91-200 carries CE and ISO 9001 certification, factory-tested before shipment, built in Tangshan. Neither certificate is a quality guarantee in the abstract — they certify that the machine was built under a documented quality system and tested against the standards before it left the factory. What they mean for you as a buyer: the documentation pack exists, the load test happened, and the warranty terms (one year standard, with extended main-frame coverage available per order) are backed by a manufacturer with a fixed address rather than a trading shell.
The same verification logic applies to every claim on the sheet. A factory that will walk you through the test procedure, the steel certificates and the documentation pack before the deposit is a factory that expects to still be answering the phone in year five.
What the Sheet Does Not Say
Three things that decide your experience with this machine are not on any datasheet, and you should raise all three at quotation:
- The duty conversation. A build quoted for single shifts is not the build quoted for two. Tell your supplier the shift pattern you actually run, not the one you aspire to.
- The supply conversation. Available voltage, frequency, spare kilowatts and the starting method — confirmed with your electrician before the build, not discovered on delivery day.
- The flow conversation. Material in, cut scrap out, and where cut pieces accumulate. A machine whose output piles up under the box spends half its shift waiting, and no specification row will warn you about it.
None of that is a reason to distrust the sheet. It is a reason to know that the sheet is the beginning of the specification, not the end of it. For the wider framework on holding a factory to its numbers, our 315-ton guide covers the next class up, and the full shear range maps every step from 200 to 2000 ton.
Buyer FAQ
Is 200 ton enough for my yard?
If your daily diet is rebar, light sections, light pipe, plate under 30 mm and mixed light scrap at 5 to 40 tons per day, yes. If continuous HMS or heavy structural work is the rule rather than the exception, compare the 630T class before ordering.
Why is daily capacity a range instead of a number?
Because material, loading, cut length and running hours move it, and any factory quoting a single number is guessing at your feed. We size against your actual profile at quotation.
Which motor configuration should I choose?
Send us your available supply details — voltage, frequency and spare kilowatts — and the configuration is confirmed in writing before the build. Generator and diesel sites typically take the lower kW package.
How is the machine tested before shipment?
Every machine undergoes load testing before shipment under our ISO 9001 quality system, with CE certification and a full documentation pack including schematics and foundation drawings.
What warranty comes with the machine?
A standard one-year warranty, with extended main-frame coverage available — terms are confirmed per order alongside the configuration.
