250 Ton Alligator Shear – Q43-250

Description

250 Ton Alligator Shear for Sale – The Busy-Yard and Contractor Machine

The Q43-250 is a 250 Ton hydraulic alligator shear for operations that have outgrown the entry class: demolition crews cutting all shift, small yards feeding a furnace every week, and shops processing bar stock by the bundle. It takes 25 mm plate, Ø55 mm round bar and longer sections on a 1,000 or 1,200 mm blade — and it still installs without a single foundation bolt.

Who the Q43-250 Is Built For

This is the working middle of the Q43 alligator shear line, and it is bought by operators whose problem is volume rather than access:

• Demolition contractors and salvage crews cutting rebar, light structural steel and mixed site debris from morning to night.
• Small and mid-size yards that started on the 200 ton class and now feed the machine instead of filling it.
• Fabrication shops and stockholders bundling bar stock and offcuts for the furnace instead of paying per-ton processing.

If your material has moved past 25 mm plate into continuous heavy sections, the machine you want is not in this line at all — it is a gantry shear, and the Q91 range starts where this class stops. We will tell you that in the quotation if it is true.

Where the 250 Ton Class Sits in the Q43 Line

The Q43 alligator shear line runs from 63 to 500 ton, and this model is its working centre. Below it, the 200 ton class handles rebar and light sections at first-machine volumes. Above it, 315 and 400 ton models exist for heavier intake still. The 250 ton is the class most often specified by buyers who need one machine to carry a busy yard — not to start one.

What stays constant across the line: lever-action cutting, foundation-free installation, one-person operation and diesel-ready power. What changes with force: plate thickness, section size and how long the machine holds its pace through the day.

What the Q43-250 Cuts

Material Ratings

Material	Q43-250 duty rating
Rebar	Construction and demolition rebar in bundles or loose — including reinforcement recovered from site stripping
Round bar	Up to Ø55 mm
Square bar	Up to 50×50 mm
Angle and channel steel	Light through medium structural profiles
I-beams	Light to medium sections within the 250 Ton force rating
Steel pipes	Single pipes, including thicker walls within the plate rating
Steel plate	Up to 25 mm
Mixed light and medium scrap	Demolition debris, salvage offcuts and busy-yard intake

These ratings assume the load sits in the blade’s high-force zone. The lever principle means force falls off toward the blade tip, so material fed at the root cuts with more force than the same section fed at the end — a detail we account for when we confirm your heaviest cross-section.

Capability Boundary

• Daily duty: light to medium ferrous — bar, rebar, light structural sections — at busy-yard volumes.
• Occasional duty: plate to 25 mm and the odd heavier section; the force exists for exactly that.
• Step up instead: continuous HMS, daily plate above 25 mm or throughput past 25 tons a day points at the 315 ton gantry class or above.

A Busy Yard’s Machine — Cycle Rate and Blade Options

Nine to twelve cuts a minute on light material, the hold-down clamped and one operator feeding: that pace is the reason this class carries a yard rather than just starting one. The 1,200 mm blade option takes longer members in a single pass, which removes the second handling that quietly eats a contractor’s afternoon on beam and angle stock.

Blades and Running Costs

Cutting edges are high-alloy tool steel at 48–56 HRC, reversible on four faces. Mixed demolition duty works the blade harder than clean bar stock, so we state the expected regrind interval against your material mix rather than quoting a figure that assumes clean scrap.

How the Q43-250 Cuts

• Step 1 — Loading: material is placed in front of the blade by hand or grapple.
• Step 2 — Clamping: the hold-down cylinder drops and holds the section against the frame.
• Step 3 — The cut: the blade sweeps down under 250 tons of hydraulic force through the lever action.
• Step 4 — Return: the assembly retracts and the machine is ready for the next load — up to a dozen cuts a minute.

Power Supply and Configuration

A 22 kW motor package is standard, with input voltage configured to your switchboard at 380V, 400V, 415V or 230V and 50 or 60 Hz. Sites without dependable grid power take the diesel engine configuration instead. Blade length, opening and control options are set from your material profile before the order is cut — the same configuration discipline we apply across the Q43 and Q91 lines.

Shipping, Commissioning and After-Sales

The Q43-250 travels as one main machine plus a spares kit, packed for container or flat-rack sea freight with a packing list and lifting plan. Installation drawings and a commissioning checklist ship with the machine, and an engineer can fly out for start-up and operator training. Spares — blades, seals, hoses and valve components — are common with the smaller Q43 classes, so stock covers more than one machine.

Why Busy Yards Choose HUAXIN

• Bought from the factory. Direct from our Tangshan plant — the people who build the shear also own the drawings and the service.
• Honest tonnage advice. If the 200 ton class covers your duty, we say so and quote that instead.
• The same blade family as the whole Q43 line, which keeps regrinds and replacements simple as intake grows.
• Proven export record. Machines working in 50+ countries, remote support around the clock and spares dispatched within 48 hours.

Other Equipment in the Line

A busy yard outgrows the alligator shear in two directions: heavy section needs a gantry shear, while mixed light and appliance material needs a shredder instead. Our dual shaft shredder line covers the second job, and a scrap metal baler handles the recovered non-ferrous fraction at the end of the line.

FAQ – 250 Ton Alligator Shear

What is the difference between the Q43-250 and the Q43-200?

Fifty tons of force and what it buys: 25 mm plate instead of 20 mm, Ø55 mm round bar instead of Ø45 mm, 1,000 and 1,200 mm blades instead of 800 and 1,000 mm, and a faster cycle at 9 to 12 cuts a minute. The frame concept, foundation-free installation and one-person operation are the same — the larger model is for yards that fill the smaller one.

What materials can the 250 ton alligator shear cut?

Round bar to Ø55 mm, square bar to 50×50 mm, rebar loose or bundled, light and medium angle, channel and I-beam sections, single steel pipes within wall limits, plate to 25 mm and mixed light-to-medium scrap. Heavier continuous sections are gantry-shear work, not this class’s.

How much does a 250 ton alligator shear cost?

Configuration decides the number — blade length, motor package, power source and mounting. We quote EXW factory-direct with the breakdown shown line by line. Send your material profile and target volume and the quotation arrives within 48 hours.

Can the Q43-250 cut rebar from demolition work?

Yes — bundled or loose, and it is one of the strongest cases for this class on a demolition site. Rebar still bedded in concrete is a different load: tell us your heaviest members and we will confirm what 250 tons honestly handles, or point you at the right gantry model.

Which blade length suits a busy yard?

The 1,000 mm blade covers general work; the 1,200 mm blade is the one to spec when long beams and angle stock should go through in one pass instead of two. Decide it against your longest regular member.

Does it run on diesel power?

Yes. The diesel engine option is the standard answer for sites without reliable grid capacity, and it keeps the machine portable in the truest sense.

Are foundation bolts required?

No. A level surface is enough, and the machine can be repositioned as the layout of the yard changes — skid and trailer mounting are options on request.

When should I buy a gantry shear instead?

When the question becomes daily tonnage rather than section size. Gantry shears hold continuous-duty ratings on HMS and take plate far beyond 25 mm; the Q91 gantry range is the next conversation, and we will start it if your numbers deserve it.

What do you need to quote the Q43-250?

Material type and mix, heaviest cross-section, target cuts or tons per day, power available and destination port. Photos of your scrap shorten the whole process.
