1) Market Background
In Brazil, scrap yards are increasingly running on dispatch discipline rather than “cut when needed.” Mixed heavy scrap from demolition, fabrication, and industrial maintenance can arrive in irregular sizes that are hard to stack and slow to load. When oversize scrap builds up, it blocks lanes, increases re-handling, and forces last-minute cutting before trucks move. As freight pressure rises and shipping windows tighten, more operators are upgrading to a horizontal container scrap shear as a dedicated sizing station—so cut size becomes predictable, staging becomes cleaner, and loading becomes easier to plan.
2) Customer Materials
The customer’s inbound stream was dominated by mixed heavy ferrous scrap, mainly:
Structural steel offcuts (beams, channels, angles) and bar stock
Plate offcuts and bundled mixed scrap from sorting lines
Oversize pieces requiring controlled holding and repeatable cutting
Occasional “awkward shapes” that previously caused repositioning and delays
3) Target Capacity
The site’s goal was to stabilize cutting output to match daily loading needs:
Target throughput aligned with the machine’s rated band: 8–10 t/h (material dependent)
Maintain a practical cutting rhythm for dispatch: 3–4 cuts/min
Reduce peak-day backlog by treating cutting as a routine step, not a last-minute task
4) Site Constraints
The customer’s operating constraints were typical for an active Brazilian yard:
Limited space near the loading lane, requiring a compact, container-oriented shear layout
Crane/grapple feeding, needing a wide mouth for mixed batches
Clear separation needed between feed zone and discharge/stacking zone to avoid traffic conflicts
Standard industrial power supply planning (380V/50Hz class, customized as required)
5) Why This Tonnage
The customer chose a 630-ton class container scrap shear because the scrap mix included heavier sections and plate that demanded stable cutting force without slowing rhythm. The decision was tied to practical sizing requirements: a wide 3700 × 2500 mm feeding mouth for mixed heavy scrap, a controlled hold cylinder (1153 kN) to reduce repositioning, and a 1500 mm blade to support consistent cut behavior. With 3–4 cuts/min and a rated 8–10 t/h capacity range, the site could size material fast enough to protect dispatch schedules without overspecifying into a larger footprint than the yard could comfortably manage.
6) Actual Configuration
Jiangsu Wanshida Hydraulic Machinery Co., Ltd. supplied 1 set Q43W-6300A horizontal container scrap metal shear machine with PLC automatic control + remote operation (Siemens), air cooling, and a matched 3-motor + 3-pump hydraulic configuration to support stable daily runtime.
7) Workflow Setup
The shear was positioned between inbound staging and outbound loading to reduce re-handling loops.
Feed → Hold → Cut → Discharge → Stack/Load
8) Shipping / Installation / Trial-Run Feedback
Container unloading and positioning were planned around the shear footprint and lifting availability on site
Installation checks focused on hydraulic cleanliness, electrical connections, and safe feed/discharge lanes
Trial run validation emphasized cutting rhythm stability, holding control on irregular pieces, and discharge staging clarity
Operator onboarding focused on consistent feeding habits and safe remote operation near the cutting zone

10) Operating Condition Notes
Best suited for mixed heavy scrap where consistent holding reduces repositioning time
Capacity 8–10 t/h depends on scrap mix, feeding stability, and staging discipline
The air cooling system supports continuous operation when the yard maintains a steady feed rhythm
The wide feeding mouth helps crane/grapple feeding of mixed batches without excessive pre-sorting
11) Customer Feedback
First change: the cutting zone became less chaotic because oversize material was processed earlier and more consistently
Second change: discharge piles became more uniform, improving stacking and reducing loading friction
Final habit: dispatch planning became calmer because the yard could rely on a repeatable sizing rhythm rather than last-minute cutting
12) Key Takeaway
For Brazil yards under shipping pressure, a container scrap shear machine creates value when it turns mixed heavy scrap into consistent, loadable pieces on a predictable rhythm. With controlled holding, a wide feeding mouth, and stable 3–4 cuts/min operation, the Q43W-6300A helps build a repeatable “cut-and-load” routine.
FAQ (3)
Q1: How do I know if a 630-ton class container shear is the right choice?
Match tonnage to your scrap thickness/section sizes and the rhythm you need to protect daily dispatch—force is only useful if it supports stable cutting.
Q2: What drives real capacity in daily operation?
Scrap mix, feeding consistency, and staging layout. A clean feed lane and stable holding reduce interruptions and improve output.
Q3: What should I prepare before installation?
Confirm crane/grapple feeding method, allocate discharge/stacking space, and verify power supply and safe traffic lanes.
