The Q43-800 scrap metal alligator shear is a hydraulic cutting machine designed for scrap-metal preparation and size reduction. It provides a maximum shearing force of 800 kN, approximately 80 tons, and is equipped with an 800 mm blade and a 7.5 kW electric motor.
The machine is mainly used to cut long, irregular or difficult-to-handle metal scrap into shorter pieces that are easier to sort, store, bale, transport and charge into a furnace.
Typical users include scrap yards, metal-processing workshops, foundries, steel warehouses, dismantling facilities and small or medium-sized recycling companies.
The Q43-800 hydraulic scrap shear uses manual feeding and can be operated through manual controls or a PLC semi-automatic system, depending on the selected configuration. It is suitable for processing rebar, round bars, square bars, light structural sections, production offcuts and selected thin-wall metal scrap.
Main performance data include:
As a practical scrap metal alligator shear, hydraulic scrap shear and metal recycling shear, the Q43-800 helps customers reduce torch-cutting work and improve scrap preparation before baling, transportation or furnace charging.
Scrap recycling companies often receive materials with inconsistent lengths, shapes and cross-sections, including:
Without proper size reduction, these materials can create several operational problems.
Long bars and irregular sections are difficult to stack neatly. They occupy valuable storage space and interfere with sorting and loading.
Flame cutting consumes fuel gas and oxygen and requires experienced operators. Frequent hot work also increases safety-management requirements.
Some long pieces exceed the chamber dimensions of a scrap metal baler. They must be cut before loading to prevent poor chamber utilization or feeding difficulties.
Long and irregular materials leave unused space inside transport vehicles and may not meet the furnace-size requirements of downstream steel mills.
For customers with moderate processing volumes, a large gantry shear or container shear may require excessive capital investment, installed power and working space.
A hydraulic alligator shear therefore provides a flexible and cost-conscious solution for small and medium-scale scrap preparation.
The Q43-800 scrap metal alligator shear combines 800 kN of hydraulic shearing force with an 800 mm cutting blade.
The operator places the scrap in the cutting area and adjusts its position according to the required finished length. The machine is then activated through manual controls or a PLC semi-automatic sequence.
The hydraulic system drives the upper blade downward against the lower blade, cutting the material into shorter and more manageable pieces.
A reference frequency of 9–20 cuts per minute supports continuous processing of bars and production offcuts. Actual speed depends on material size, hardness, feeding efficiency and operating method.
Within the rated cutting range, hydraulic mechanical shearing can replace part of the flame-cutting work, reducing fuel consumption and the frequency of open-flame operations.
Pre-cutting long material allows it to fit more efficiently inside the compression chamber of a scrap metal baler.
Shorter, more regular scrap is easier to sort, stack and load, improving the use of storage and transport space.
The machine can use manual controls or PLC semi-automatic operation. Customers can select the configuration according to labor availability, throughput and safety-management requirements.

The stated 35×35 mm square bar and Ø40 mm round bar capacities are reference values.
Actual cutting capacity depends on:
High-strength alloy steel, stainless steel, hardened material and bundled bars may require a lower cutting size than ordinary low-carbon steel.
Customers are advised to provide material photos, dimensions and material grades before final model selection.
The machine can cut collected rebar, round bars, angle steel, bar ends and production offcuts into manageable sizes.
Long scrap can be cut before entering a scrap metal baler, helping improve chamber loading and compression efficiency.
The shear can process bar ends, steel cut-offs and production scrap generated during machining and fabrication.
It can cut unusable short lengths, irregular sections and rejected metal materials for recycling.
The machine helps reduce scrap to dimensions more suitable for furnace openings and material-charging systems.
It can process selected steel bars, small components and light structural scrap generated during dismantling. Oversized parts require a higher-capacity machine.
The alligator shear can be combined with conveyors, scrap balers or sorting equipment to create a basic metal-preparation workflow.
The Q43-800 alligator shear generates cutting force through a hydraulic system.
The operator places the scrap material in the blade area and determines the required cutting position.
The material is positioned on the blade seat or working table. The operator must keep the scrap stable and keep hands outside the hazardous cutting zone.
When the control is activated, the electric motor drives the hydraulic pump and supplies pressurized oil to the cutting cylinder.
The hydraulic cylinder pushes the upper blade downward. The upper and lower blades apply opposing forces and cut through the scrap.
After cutting, the hydraulic system returns the upper blade to its original position.
The operator moves the remaining material or loads the next piece and begins another cutting cycle.
Manual operation is suitable for mixed scrap with varying dimensions. PLC semi-automatic operation can improve the consistency of repeated cycles.
Selecting a scrap metal alligator shear requires more than comparing the nominal shearing force.
Customers should identify whether they process ordinary carbon steel, rebar, round bar, angle steel, channel steel, stainless steel or alloy material.
Materials with the same dimensions may require very different cutting forces.
Useful information includes:
For ordinary square steel up to approximately 35×35 mm or ordinary round steel up to approximately Ø40 mm, the Q43-800 may be considered as a reference model.
The stated 9–20 cuts per minute is a reference cycle frequency under standard conditions. Actual hourly output depends heavily on manual feeding speed and material weight.
High-volume mixed scrap may require a larger alligator shear, gantry shear or container shear.
An 800 mm blade provides space for wider scrap and different offcut shapes. However, it does not mean that maximum-thickness material can be cut across the entire blade length at the same time.
Manual control is suitable for varied materials and moderate production.
PLC semi-automatic operation can improve cycle consistency, although the material is normally still loaded and positioned manually.
The standard motor power is 7.5 kW. Before production, customers should confirm:
The motor and electrical configuration can be confirmed according to the customer’s local power supply.
The machine should not be selected only according to the current minimum requirement. Customers expecting significant growth may benefit from reserving additional cutting capacity.
Ø40 mm can be used as a reference capacity for ordinary low-carbon round steel. High-strength alloy steel, stainless steel or hardened steel may require a smaller cutting diameter.
Several bars may be cut depending on their diameter and material grade. However, bundled bars significantly increase cutting resistance and must not be calculated according to the maximum capacity for a single bar.
The standard feeding method is manual. The operating system can be manual or PLC semi-automatic, but material feeding and positioning are normally completed by the operator.
Blade life depends on material hardness, operating hours, cutting position, operator practice and maintenance. Worn blades may be turned, re-ground or replaced according to their condition.
The Q43-800 is more suitable for small and medium-scale scrap preparation. Heavy structural scrap, thick plate, large sections or high-volume mixed material may require a larger alligator shear, gantry shear or container shear.
