Test weight fabrication

Product Formats

• Portable & Small Kits (1,000 kg – 5,000 kg) — modular plates and palletised sets for on-site scale and load cell calibration.
• Medium Sets (5,000 kg – 20,000 kg / 5 t – 20 t) — stackable modules and pallet sets for workshop and mid-range proof tests.
• Large Proof Blocks (20,000 kg – 50,000 kg / 20 t – 50 t) — heavy modular blocks or single monolithic blocks for crane proof-loading and structural tests.
• Custom Splits — common examples: 5×10 t, 10×5 t, 25×2 t, 50×1 t. We’ll recommend the best split for transport and site handling.

Why PTI Test Weights Fabrication?

• Full-range supply: 1,000 kg → 50,000 kg (1 t → 50 t).
• Precision fabrication: CNC machining and heavy-duty structural steel fabrication for frames and blocks.
• Traceable calibration: ISO/IEC 17025 calibration on request.
• Certified lifting: padeyes, lugs, shackles, and lifting frames supplied and proof-tested.
• Turnkey service: design, fabrication, proof testing, transport planning and on-site placement.

Key Features & Inclusions

• Serial-tagged modules with tolerance and calibration records.
• Certified lifting points; compatible with spreader beams and proof frames.
• Finishes: shot-blast + primer + epoxy paint, galvanizing or stainless options.
• Documentation pack: MTCs, weld records, NDT reports, proof-load and calibration certificates.
• Optional add-ons: dynamometers, rigging kits, on-site placement support.

Certification, Testing & Traceability:

• Proof-load testing at 1.25× or 1.5× WLL with certified reports.
• ISO/IEC 17025 calibration for laboratory verification.
• NDT (MPI/UT) on fabricated frames and assemblies.
• Recertification and recalibration services available.

Handling, Transport & Logistics:

• Modular design to reduce transport costs and permit issues.
• Lift plans, certified slings/shackles, lifting beams and placement support included.
• Modules palletised/crated with safe lifting points.
• Custom sizing per client transport limits.

How to Order / What We Need to Quote:

To prepare a formal proposal, send us:

• Total required mass (e.g., 50 t / 20 t / any between 1,000 kg–50,000 kg).
• Preferred modular split (e.g., 5×10 t, 10×5 t, 50×1 t).
• Required proof-load multiplier (typical 1.25× or 1.5×) and calibration class (industrial or ISO/IEC 17025).
• Finish/environment (paint, galvanize or stainless).
• Site & delivery location (for transport planning and permit checks).
• Any dimensional or handling limits per module (max width/height/unit weight).
• Primary application (crane proof, scale calibration, lab use, etc.).
