The Challenge

A heavy steel fabrication plant near Linz, Austria, ships welded beams and machine bases across Europe. The facility straps around 180 heavy pallets per day using 25 mm steel strap with separate steel buckles and two older manual tools.

The previous method required fitting and crimping a buckle on every strap, adding time and cost. Each pallet typically used 4 straps × 2 buckles. Buckles cost the plant about €0.15 each, and operators spent roughly 2 minutes per pallet just handling and closing buckles.

Frequent joint slippage on over-tensioned or poorly crimped buckles led to an average of 7 pallets per day needing re-strapping after internal checks or during truck loading. Transport damage claims from shifted loads averaged €800 per month. With two operators tied up for about 6 hours/day on strapping alone, the plant needed a safer, faster, and cheaper solution.

The Solution

The plant introduced the A4 Sealless Steel Strapping Tool to replace the buckle-based tools on all outbound heavy pallets. The A4 was chosen for its proven joint strength of 80–85% of strap tensile strength, ensuring secure containment of very heavy loads without separate buckles.

Running at about 60% of its maximum 8000N tension capacity, the A4 provides consistent, reliable tensioning while protecting strap integrity. Its compatibility with 16–32 mm steel straps matches the plant’s existing 25 mm stock, and the 4.2 kg lightweight, compact design allows operators to work comfortably around large welded fabrications and tight loading areas.

Operators were trained in under one shift to use the sealless joint: tension, seal, and cut in a single workflow. The plant installed three A4 tools to cover two shifts, with one tool kept as a backup to minimise downtime.

ROI Calculation

Before – Buckle Strapping:

• Daily volume: 180 pallets/day, avg. 4 straps per pallet
• Buckles used: 2 per strap → 8 per pallet → 1,440 buckles/day
• Buckle cost: €0.15 each → 1,440 × €0.15 = €216/day
• Operator time: 3.0 minutes per pallet (including buckles) → 180 × 3 = 540 minutes ≈ 9.0h/day
  At an effective labour cost of €20/h, strapping labour ≈ €180/day
• Rework: 7 pallets/day × 5 minutes = 35 minutes ≈ 0.6h/day extra labour
• Total daily cost (buckles + labour + rework): approx. €216 + €192 ≈ €408/day

After – A4 Sealless Steel Strapping Tool:

• No buckles: €216/day in buckle cost eliminated
• New cycle time: 1.8 minutes per pallet → 180 × 1.8 = 324 minutes ≈ 5.4h/day
  Labour cost: 5.4h × €20 ≈ €108/day
• Rework reduced: from 7 to 2 pallets/day → 2 × 5 minutes = 10 minutes ≈ 0.2h/day
• Estimated damage claims reduced by 50%: from €800/month to €400/month (≈ €18/day saving)
• Total daily cost with A4 (labour + residual rework): approx. €120/day

Daily savings: €408 − €120 ≈ €288/day.
Investment:
3 × A4 tools at €690 each = €2,070
Monthly savings (22 working days): €288 × 22 ≈ €6,336
Payback period: under 1 month, even allowing for maintenance and training time.

Results

Within the first quarter, the plant confirmed a sustained over 40% reduction in total strapping-related costs and a clear increase in loading bay throughput. Operators now complete the same daily volume with one person instead of two for part of the shift, while maintaining secure, consistent joints on very heavy loads.

Transport damage linked to strapping failures has dropped noticeably, and supervisors report fewer last-minute re-strapping interventions at the truck. The A4 tools have become the standard for all heavy-load lines in the facility.

“Switching to the A4 sealless tools removed our buckle purchases overnight and cut strapping time on each pallet by more than a third, with no compromise on load safety.” — Markus Huber, Logistics Manager, StahlForm GmbH / Linz, Austria
