Core Product Range & Spesifikasi teknis

Alloy Steel Lifting Chains (G80 / Nilai 8 & G100 / Nilai 10)

• Chain Grades: G80 (Minimum Break Load = 800 N/mm²), G100 (Minimum Break Load = 1000 N/mm²)

• Chain Diameters (D): Typically ranging from 6mm (1/4″) to 26mm (1″) (Diameter khusus tersedia).

• Batas beban kerja (Wll): Directly proportional to chain diameter and grade. Example ranges:

  • 6mm G80 Chain: Kira-kira. Wll 1.0 tonne
  • 10mm G80 Chain: Kira-kira. Wll 3.2 ton
  • 13mm G80 Chain: Kira-kira. Wll 5.3 ton
  • 16mm G80 Chain: Kira-kira. Wll 8.0 ton
  • 10mm G100 Chain: Kira-kira. Wll 4.0 ton
  • (WLLs are rigorously tested and marked on each chain; always refer to markings)

• Bukti Uji Beban: Typically 2x WLL (Per ISO 4778 / DI DALAM 818-4).

• Break Test Load: Minimum 4x WLL for G80, 5x WLL for G100 (Destructive testing on samples).

• Elongation at Break: ≤ 15% (Measured over 3 tautan).

• Tolerance: Link dimensions manufactured to tight tolerances as per ISO 4778.

• Permukaan: Smooth finish, optionally galvanized (Minimal. average coating weight: 610 g/m² for Grade A) or painted for corrosion protection.

Lifting Hooks & Majelis

• Hook Grades: Manufactured to Grade 4, 5, 6, 8 (Equivalent to ISO 7592 / DI DALAM 1677-1). Nilai 8 (Paling Umum, Minimal. Yield Strength = 640 N/mm²) is standard for heavy-duty use.

• Batas beban kerja (Wll): Berkisar dari 0.25 tonnes to 50+ ton, depending on hook type, ukuran, dan desain.

• Bukti Uji Beban: Typically 2x WLL.

• Break Test Load: Minimum 3x WLL for Grade 4, 4x WLL for Grade 5, 5x WLL for Grade 6/8.
