TITAN alligator shears are designed for cold shearing metal bars, metal profiles, pipes and tubes, as well as small- to medium-sized scrap metal. They cut long or awkwardly sized scrap into shorter pieces that are better suited to subsequent handling, transport, sorting, or furnace charging. For the TITAN Q43 Series, shearing force, blade opening, and cutting rate are matched to the type of metal, its cross-sectional shape and dimensions, required throughput, and target cut specifications. The feeding method is selected based on project requirements, and an automatic feeding system can be added when required.
The cross-sectional shape and dimensions of scrap metal, together with the target cutting length, determine the actual shearing requirements. The TITAN Q43 Series is mainly used for cold shearing metal bars, metal profiles, pipes and tubes, and small- to medium-sized scrap metal. Shearing capacity and machine configuration are selected to match the actual material conditions.
Q43 Series alligator shears can process a range of metal bars, profiles, pipes and tubes, as well as other small- to medium-sized metal scrap suitable for shearing.
Material name alone provides only a preliminary indication of suitability. Whether a material can be sheared effectively also depends on its cross-sectional shape and dimensions and the target cutting specification. The appropriate machine model should ultimately be selected based on the actual material.
Round bar, square bar, steel pipe, and profiles such as steel channel and I-beam have different cross-sectional shapes. During model selection, the material's cross-sectional shape should be considered when determining the required blade opening and shearing capacity.
Even within the same material type, differences in diameter, width, thickness, or overall section size change the shearing capacity required from the machine. Actual scrap dimensions should be provided before model selection; material name alone is not sufficient.
The required length of each cut piece depends on subsequent handling, transport, or furnace charging requirements. Defining the target cutting length helps determine the actual feeding and shearing method.
The following data were recorded during actual material tests on TITAN Q43 Series alligator shears. They show cutting performance for specific materials, section sizes, and machine models. Results may vary with material condition, machine configuration, and operating conditions.
The figures above are actual test records for specific materials, section sizes, and machine configurations. They should not be interpreted as fixed performance values for all operating conditions. Actual shearing capacity, cuts per minute, and energy consumption depend on the material cross-section and dimensions, machine model, and operating conditions.
TITAN Q43 Series alligator shears are available with different shearing forces, blade lengths and openings, and drive configurations. The appropriate model should be selected by considering the metal type, cross-sectional shape and dimensions, target cutting length, required throughput, and feeding conditions together, rather than by shearing force alone.
The Q43 Series includes seven standard models ranging from 1200 kN to 5000 kN. Across the range, maximum shearing force, blade length, and maximum blade opening define different capability ranges for matching metal bars, profiles, pipes and tubes, and small- to medium-sized scrap metal of different dimensions.
| Model | Maximum Shearing Force | Blade Length | Maximum Blade Opening | Motor Power |
|---|---|---|---|---|
| Q43-1200 | 1200 kN | 800 mm | 340 mm | 15 kW |
| Q43-1600 | 1600 kN | 800 mm | 380 mm | 2 × 18.5 kW |
| Q43-2000 | 2000 kN | 1000 mm | 460 mm | 22 kW |
| Q43-2500 | 2500 kN | 1200 mm | 530 mm | 2 × 15 kW |
| Q43-3150 | 3150 kN | 1200 mm | 530 mm | 2 × 18.5 kW |
| Q43-4000 | 4000 kN | 1500 mm | 670 mm | 2 × 22 kW |
| Q43-5000 | 5000 kN | 1600 mm | 700 mm | 2 × 22 kW |
These are the standard specifications for TITAN Q43 Series machines. They define the basic capability range of each model and should not be interpreted as fixed cutting specifications that a given material can achieve under all operating conditions. The appropriate model must be confirmed based on the material properties and its cross-sectional shape and dimensions.
Selecting an alligator shear means matching the material specifications to the machine's shearing capacity, blade length and opening, and on-site operating requirements. Knowing only that the material is "steel scrap" or a "metal profile" is usually not enough to determine the correct model.
First identify whether the material is round bar, square bar, steel pipe, steel channel, I-beam, steel plate, aluminum profiles, or another type of metal scrap. Even when overall dimensions are similar, different metals and cross-sectional shapes can impose different shearing requirements.
Provide the actual round-bar diameter, square-bar side dimension, and the width, thickness, or other relevant dimensions of profiles. Cross-sectional dimensions are an important basis for determining the required shearing force and blade opening, and are one of the key factors when choosing between Q43 models.
Blade length and maximum blade opening vary by model. For materials with larger cross sections or those requiring more working clearance in the cutting area, shearing force and blade length/opening must be considered together rather than comparing machine “tonnage” alone.
The required length of the cut pieces should be determined by downstream handling, transport, sorting, or furnace-charging requirements, and the actual cutting process should be arranged together with the incoming material length and feeding method.
Determine the operating pace and feeding method based on the amount of material to be processed per day or shift, incoming material length, individual piece weight, and staffing. For projects requiring continuous feeding, an automatic feeding system can be provided if required for the project.
An alligator shear is usually not selected in isolation. How the incoming material is fed into the machine, how the cut pieces are moved downstream, and the site's staffing and operating pace all affect the final configuration.
Determine the metal type, cross-sectional shape and dimensions, incoming material length, and target cutting length to establish the basic conditions for model selection.
Based on the shearing capacity, blade length, and blade opening required for the actual material, identify the appropriate equipment range from Q43-1200 to Q43-5000.
Arrange feeding according to incoming material length, weight, throughput, and staffing. An automatic feeding system can be provided if required for the project to support continuous shearing operations.
According to the project process, direct the shorter cut pieces to subsequent handling, transport, sorting, storage, or furnace charging.
The TITAN Q43 Series uses a hydraulic system to close the hinged cutting jaw and cold-shear metal bars, profiles, pipes and tubes, and small- to medium-sized scrap metal entering the cutting area. The actual shearing process depends on the combination of the cutting-jaw structure, shearing force, blade dimensions, and the cross-sectional characteristics of the material.
Metal bars, profiles, pipes and tubes, or other suitable scrap metal are fed into the open cutting jaw. The material is positioned according to the target cutting length.
The motor drives the hydraulic pump, which pressurizes the hydraulic oil. The hydraulic system then transmits this pressure to the hydraulic cylinder, providing the driving force required to close the cutting jaw.
The hydraulic cylinder drives the cutting jaw closed. The upper and lower cutting members close in an alligator-like motion and act on the metal cross-section to complete the cut under cold conditions.
After shearing, the shorter pieces leave the cutting area and the incoming material can continue feeding for the next cut. The cut material then moves on to handling, storage, transport, sorting, or furnace charging.
The key structural difference between an alligator shear and other scrap-metal shearing equipment is its hinged cutting-jaw arrangement. Once the material enters the jaw area, the hydraulic cylinder drives the jaw closed so that the shearing force acts directly on the metal cross-section to be cut.
Actual shearing capacity is therefore not determined by a single machine “tonnage” value. Shearing force determines the force available for cutting, while blade length and maximum blade opening define the effective cutting area. The material type and its cross-sectional shape and dimensions determine the shearing capacity required for the specific application. The Q43 Series combines different shearing-force levels and cutting-jaw dimensions to match different metal cross-sections.
The Q43 alligator shear completes each shearing cycle through the combined operation of the frame, shear blades, hydraulic system, and electrical control system. Together, these elements form a complete cutting station for material entry, power transmission, shearing action, and operating control.
The hinged cutting-jaw structure opens and closes to shear the metal. Different Q43 models use different blade lengths and maximum blade openings to accommodate bars, profiles, pipes and tubes, and other suitable scrap metal with different cross-sectional dimensions.
The hydraulic system consists of the hydraulic pump, oil tank, hydraulic lines, hydraulic cylinder, and related components. Driven by the motor, the hydraulic pump generates hydraulic pressure, which is transmitted through the hydraulic system to the cylinder to drive the shearing motion. Different Q43 models provide corresponding shearing-force levels for different material cross-section requirements.
The shear blades act directly on the metal cross-section during cutting. TITAN Q43 Series machines use high-strength alloy blades, with blade length and cutting-jaw dimensions configured according to the model to meet different material and cross-section requirements.
The electrical control system includes electrical components, sensors, and a PLC. Together with pressure monitoring, limit switches, and machine guards, it controls the shearing action and provides protection during machine operation.
TITAN Q43 Series alligator shears have been used in actual projects involving different countries, materials, and scrap-processing conditions. From various forms of steel scrap and aluminum profiles to mixed steel scrap, the machine model and configuration are matched to the material cross-section, cutting requirements, and site production conditions. The following operating results come from specific customer projects.
The customer is a small- to medium-sized steel scrap processor. Given constraints on production scale and equipment investment, the customer needed to improve the shearing efficiency of several forms of steel scrap while keeping equipment investment under control. Its existing mechanically driven shearing equipment was large, noisy, and less flexible in operation, creating practical difficulties on site.
The results above come from specific customer project records and should not be interpreted as fixed performance for all materials or operating conditions. Actual shearing capacity, throughput, operator requirements, and cut quality depend on the material type, cross-sectional shape and dimensions, machine model, feeding method, and site operating conditions.
Feedback from a customer using this TITAN machine in a real scrap processing project.
TITAN's engineering team understood the challenges of oversized steel scrap and delivered a reliable shearing solution that improved productivity and reduced manual processing requirements.
TITAN's service does not end with equipment delivery. Depending on project requirements, we can provide equipment installation and commissioning as well as operator training. After the machine is put into operation, we can provide technical support for continued operation through remote diagnostics, field service, and spare-parts supply.
Based on the Q43 model and project configuration, the main machine is positioned, electrical connections are made, and any necessary hydraulic or piping connections are completed to prepare the equipment for integrated commissioning.
The hydraulic, electrical, and control systems are commissioned together. Hydraulic pressure, cutting-jaw opening and closing, limit-switch operation, and control logic are checked to confirm that the machine can complete the feeding and shearing cycle according to the defined sequence.
Training is based on actual machine operation and covers start-up and shutdown, feeding and shearing operations, handling abnormal conditions, safe operation, and basic routine maintenance. This helps operators understand the basic operating and processing workflow of the Q43 alligator shear.
After the equipment is put into operation, TITAN can assist with remote diagnostics based on fault symptoms, alarm information, and operating status. If further action is required, field technical service and appropriate spare-parts support can be provided depending on the project circumstances.
The specific scope of installation, field service, and warranty is determined by the project configuration, delivery region, and contractual terms.
