Hydraulic Gantry 500 Ton Scrap Metal Shear Machine – Q91-500

Description

500 Ton Scrap Metal Shear for Sale – Built for Demolition Intake

The Q91-500 is a 500 Ton hydraulic scrap metal shear designed for one of the hardest feed materials in the recycling business: demolition offcuts. Building skeletons, bridge sections, floor plate and structural offcuts that arrive irregular, oversized and often with concrete still attached. That mix punishes a machine in ways that light mixed ferrous never does — in impact loads, in frame fatigue and in blade wear — and it is the reason this tonnage class exists.

Who the Q91-500 Is Built For

This is the machine for plants whose intake leans toward demolition rather than shop scrap:

• Demolition and dismantling contractors processing their own recovered steel rather than selling it unprocessed.
• Yards specialising in structural and heavy plate offcuts, where the heavy share of intake rules out the mid tonnages.
• Operations feeding a furnace directly, where sized charge consistency and throughput matter more than handling light scrap efficiently.

Daily output for this class runs 45 to 60 tons. The buyers who get the most from it are those whose previous machine was technically strong enough but practically overwhelmed — a 400 ton shear asked to eat irregular demolition sections all day is one of the fastest ways to shorten a machine’s life.

Why Demolition Material Demands a Step Up

Demolition input is not simply heavier scrap — it behaves differently. Sections arrive bent and twisted, plate comes with concrete attached that grinds blade edges instead of shearing cleanly, and every cut lands at an unpredictable angle. A shear sized for mixed ferrous will still make these cuts, but the cost shows up in faster blade consumption, more frequent cylinder seal attention and a frame absorbing loads it was not profiled for. The 630 ton continuous-duty shear is the class above this one and takes even more punishment; the 500 ton scrap metal shear sits at the point where demolition duty becomes comfortable rather than merely possible.

When the 500T Beats the 400T

If a meaningful share of your intake is demolition material — irregular sections, plate with concrete attached, oversized offcuts — the 500 ton class is the better buy even though the paper difference is only 100 tons. The extra force and frame margin are precisely what that material consumes, and the machine pays for itself in blade life and downtime rather than in capability.

When to Go Straight to 630T

If your intake has already shifted to deliberately heavy ferrous — continuous HMS 1 & 2, daily heavy plate, mill-scale volumes above 60 tons/day — then the Q91-630 is the right tier and the 500T would be a stopgap. Buyers whose intake is genuinely mixed but demolition-heavy will find the 500 ton scrap metal shear the better-balanced machine.

What the Q91-500 Cuts – Demolition Offcuts, Heavy Plate and Concrete-Adhered Steel

Material Duty Ratings

Material	Q91-500 duty rating
Steel plates	Up to 50 mm continuously; up to 65 mm occasionally
Demolition sections	Core application — bent, twisted and oversized structural offcuts from building and bridge dismantling
Concrete-adhered steel	Floor plate and sections with concrete attached, where clean separation is not possible at source

HMS 1 & 2	Not a continuous-duty rating — heavy and mixed ferrous all day, yes; continuous HMS belongs on a 630T or above

Capability Boundary for Demolition Duty

• Continuous duty: demolition offcuts, concrete-adhered sections, heavy plate to 50 mm and heavy structural profiles, all shift long.
• Occasional duty: plate up to 65 mm and the exceptional oversize member. Occasional means occasional.
• Step up instead: if your intake becomes deliberately heavy ferrous — continuous HMS, daily plate above 65 mm, or volumes beyond 60 tons/day — the 1000 ton high-capacity shear is the tier to size to.

Frame, Cylinders and Blade Wear on Demolition Duty

Demolition material loads a shear unevenly, so the frame matters more than the force figure. The Q91-500 uses a stiffened gantry structure with oversized cylinders and premium valve blocks sized for impact loading rather than steady cycling, and a 5 to 6 metre feeding tank that lets long members feed without being pre-cut by hand. Blades are H13 or M6V tool steel at 56–62 HRC, four-sided reversible; on demolition duty, expect regrind intervals to run shorter than on clean mixed ferrous, because concrete and abrasion consume edges that a clean cut would not touch. We state the expected interval for your material mix in the quotation rather than publishing one number that fits no real demolition yard.

Shearing Cycle – How the Q91-500 Works

Material drops into the 5–6 metre tank; the side rams clamp and compress the charge against the rear support; the moving blade descends and sizes the material to the chamber length; sized pieces discharge behind the machine while the blade returns. Cycle time is 20 to 35 seconds per cut, with irregular demolition sections at the upper end of that band. For furnace charging, the chamber length is what determines charge size — that is set from your furnace requirement, not from the catalogue.

Power Supply, Control and Safety

Standard motor packages are 2×37 kW or 2×45 kW, selected against your intake profile and target throughput, with voltage configured to your switchboard at 380V, 400V, 415V or 230V, 50 Hz or 60 Hz. Full PLC automation sequences the cycle, remote operation keeps the operator clear of the shear zone, and an emergency stop reacts to abnormal hydraulic pressure or machine condition. Grid, diesel generator or on-site power configurations are all available, sized to the final motor package.

Shipping, Commissioning and After-Sales

The Q91-500 ships as separate heavy items — gantry frame and shear head, cylinder packages, hydraulic power unit and electrical cabinet — packed for container or flat-rack sea freight, with a packing list and lifting plan matched to your receiving crane capacity. Installation drawings and a commissioning checklist come with the machine, and an engineer can attend site for start-up and operator training. Consumable spares cover blades, seals, valve components and hoses, and blade geometry is common to the Q91 family so replacements stay straightforward.

Why Demolition Yards Choose HUAXIN

• We write the demolition boundary down. The 500 ton scrap metal shear quotation states the material mix it is rated for, including what it should not be asked to eat daily.
• Chamber length set to your furnace. Charge size is a production decision, so it is configured from your end-use rather than left at a catalogue default.
• Frame margin specified for impact, not just force. Cylinders, valve blocks and gantry profiling are chosen for uneven demolition loading.
• Factory-direct from Tangshan. Buying a 500 ton scrap metal shear straight from the manufacturer keeps the specification, the spares and the warranty in one pair of hands.
• Straight tonnage advice. If your intake is drifting toward continuous HMS, we will point you at the 630T before you order.

Related Equipment

Demolition output is rarely clean: panel, section and wiring come out of the same structure. The 500 ton shear handles the structural side, while a scrap metal shredder opens up the light fraction for separation. Add a scrap metal baler and the non-ferrous fraction ships as dense, saleable bales rather than loose material.

FAQ – 500 Ton Scrap Metal Shear

Can the Q91-500 cut steel with concrete still attached?

Yes — that is one of the reasons this tonnage class exists. Floor plate and sections with concrete attached are a core demolition application, and the 500 ton class takes that abrasion and impact loading all day. Expect blade edges to wear faster than on clean mixed ferrous, which is why we state a regrind interval for your actual mix rather than a single optimistic figure.

Is the Q91-500 a demolition shear or a general ferrous shear?

Both, with demolition as its strength. It sizes general mixed ferrous and structural work comfortably, and it is the tier we recommend when demolition offcuts are a significant daily share of intake. If your intake is mostly clean shop scrap, the 400 ton ferrous workhorse will do the same job at a lower price.

What plate thickness can the Q91-500 handle?

Up to 50 mm continuously and up to 65 mm occasionally. If plate above 65 mm arrives daily, or your throughput target passes 60 tons/day, the 630T continuous-duty class is the right step.

Does the Q91-500 cut baled scrap?

No. Baled scrap is a 1000 ton class capability in this range — the Q91-500 is specified for demolition offcuts and heavy structural material. If bales are a significant part of your intake, size the line to the 1000 ton baled-scrap-capable shear instead.

What should I send to get a 500T quotation?

Your material mix with the demolition share, the heaviest plate or section you see regularly, target tons per day, feeding method, site power, and the furnace or end-use your sized charge feeds. From those figures we fix blade length, chamber length, tank length, motor package and automation level.

Can the Q91-500 run on a diesel generator?

Yes — grid, diesel generator and on-site power configurations are all available, with voltage matched to your supply before shipment. For demolition duty with impact loading, size the power package with margin above the motor rating.

How much does a 500 ton scrap metal shear cost?

Configuration drives the number: blade length, motor package, tank length and the demolition duty the frame is rated for all move it. We quote EXW, factory-direct, with the specification written against your intake rather than a list price. Send us your material mix and target tons per day and the quotation follows within 48 hours.
