Jiangsu Nanyuan HydraulicBuyers comparing QW series hydraulic container shears need more than a force rating. Material shape, maximum feed size, loading method, required cut, site layout and electrical supply determine whether a proposed machine fits the yard.
Jiangsu Nanyuan Hydraulic is a China manufacturer of hydraulic scrap-processing equipment. This guide explains how to compare the current QW range and what to send a supplier before requesting a quotation.
QW container shear model overview
The table below summarizes model information shown in Nanyuan’s product archive. It is a starting point for discussion, not a final order specification. Confirm the current feed opening, shear height, installed power, cycle, transport arrangement and capacity assumptions in the model-specific quotation.
| Model | Archived maximum shear force | Archived shear width | Selection note |
|---|---|---|---|
| QW-400 | 400 ton | 1,400 mm | Confirm the largest feed section and required cut before treating the force figure as proof of suitability. |
| QW-500 | Confirm | Confirm | Request the current specification because this model is absent from the older comparison table. |
| QW-630 | Confirm | 1,400 mm | The archive also lists a 400 mm shear height; verify the current configuration. |
| QW-800 | 800 ton | 1,600 mm | Compare the complete loading, cutting and discharge cycle for the buyer’s material. |
| QW-1000 | 1,000 ton | 1,800 mm | Check site access, power and handling equipment together with the larger nominal rating. |
1. Describe the scrap stream
List the main metal grades, usual piece shapes and largest pieces that arrive regularly. Separate loose sheet, profiles, pipes, beams and mixed bulky scrap in the project brief. Add representative photos with a known scale and show any attachments or contamination.
A nominal container size or shear force cannot establish suitability for every material form. If the stream changes during the day, provide the approximate share of each material and identify the most difficult pieces.
2. Define the required cut and downstream process
Ask the receiving mill, trader or next process for its preferred cut length or section. Record whether grades must remain separate, how the cut pieces will be collected and whether the output goes to a furnace, truck, container or another processing step.
Ask the supplier to state the material, feed preparation and operating conditions used for any capacity or cycle estimate. Output can change with material density, loading rhythm and cut settings.
3. Map loading and discharge
Draw the route from the stockpile to the shear. Note the excavator or loader type, approach direction, working radius and operator sightlines. Show where oversized pieces are prepared and where processed scrap is discharged.
- Can the loader reach the full feed area without obstructing discharge?
- Can the operator see the loading and cutting zones?
- Where will cut material accumulate during a shift?
- Is there clearance for cleaning, blade work and hydraulic maintenance?
- Can service vehicles and lifting equipment reach the machine?
4. Compare container shear and gantry shear layouts
A container shear and a gantry shear can serve different yard flows even when both cut scrap. Compare the feed chamber or box, hold-down and cutting sequence, loading pattern, discharge path, foundation needs and relocation plan. A yard with frequent layout changes may value a compact arrangement, while another project may need a fixed line built around steady high-volume feeding.
Use the gantry shear range as a second reference when the material flow or site plan does not fit a container shear.
5. Confirm utilities and installation scope
- Available voltage, frequency and connected power
- Foundation, drainage and floor conditions
- Clearance for loading, discharge and maintenance
- Transport and lifting route into the final position
- Ambient temperature and hydraulic cooling requirements
- Local guarding, electrical and operating requirements
6. Compare supplier quotations on the same scope
Send each supplier the same material and site brief. Ask the response to identify the recommended model, reason for selection, feed limits, throughput assumptions, included controls, layout, foundation requirement, factory test, spare parts, packing, commissioning and warranty scope.
Check whether the quotation covers only the shear or also includes feeding, discharge, electrical changes and installation support. A lower quotation can reflect a smaller scope rather than an equivalent machine.
QW hydraulic container shear RFQ checklist
- Material grades, forms and representative photos
- Typical and maximum feed dimensions
- Required cut size and downstream use
- Tonnes per hour or per shift, plus operating hours
- Loader or excavator type and loading direction
- Available footprint, foundation and discharge route
- Destination country, voltage, frequency and phase
- Required controls, commissioning, spares and delivery timing
Request a model-specific proposal
Review Nanyuan’s QW series hydraulic container shear range. Then send the material photos, largest feed dimensions, cut target, production target and site details for a focused model discussion. Final specifications, capacity and commercial terms must be confirmed in the current quotation.
QW hydraulic container shear buyer questions
What should a buyer send before requesting a QW container shear quotation?
Send representative material photos, metal grades and forms, typical and maximum feed dimensions, required cut size, production target, loading equipment, available footprint, discharge route, destination country and electrical supply. Also identify the required controls, commissioning, spare-parts and delivery scope.
Does nominal shear force alone select a container shear?
No. Material shape, maximum feed size, loading method, required cut, site layout and electrical supply all affect suitability. Ask the supplier to state the feed limits and operating assumptions behind the proposed model.
How should QW container shear quotations be compared?
Send every supplier the same material and site brief. Compare the recommended model, reason for selection, feed limits, throughput assumptions, controls, layout, foundation requirement, factory test, spare parts, packing, commissioning and warranty scope.
When should a buyer compare a gantry shear with a container shear?
Compare both layouts when the material flow or site plan does not clearly fit a container shear. Review the feed chamber or box, hold-down and cutting sequence, loading pattern, discharge path, foundation needs and relocation plan for the actual yard.
