Core Product Range & Технические спецификации

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

• Chain Grades: G80 (Minimum Break Load = 800 Н/мм²), G100 (Minimum Break Load = 1000 Н/мм²)

• Chain Diameters (д): Typically ranging from 6mm (1/4″) to 26mm (1″) (Доступны нестандартные диаметры).

• Предел рабочей нагрузки (Wll): Directly proportional to chain diameter and grade. Example ranges:

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

• Proof Test Load: Typically 2x WLL (Per ISO 4778 / В 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 ссылки).

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

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

Lifting Hooks & Сборки

• Hook Grades: Manufactured to Grade 4, 5, 6, 8 (Equivalent to ISO 7592 / В 1677-1). Оценка 8 (Наиболее распространенный, Мин. Yield Strength = 640 Н/мм²) is standard for heavy-duty use.

• Предел рабочей нагрузки (Wll): Ranges from 0.25 tonnes to 50+ тонны, depending on hook type, размер, и дизайн.

• Proof Test Load: Typically 2x WLL.

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

• Крючок для открытия горла (С): Precisely controlled according to WLL and standard dimensions (НАПРИМЕР., В 1677-1).

• Shank Diameter/Width: Sized according to WLL and connection type (НАПРИМЕР., eye diameter, clevis pin hole).

• Latch Types: Forged safety latches on self-locking hooks, designed to withstand impact and prevent accidental release. Latch engagement tested.

• Материал: Высокопротивные сплавные стали (НАПРИМЕР., 34CRMO4, 30CrNiMo8), forged and heat-treated.

• Поверхность: Shot blasted, optionally galvanized or painted.

Ключевые функции & Benefits of Weihua Lifting Chains and Hooks

• Бескомпромиссная сила & Долговечность: Forged or fabricated from high-grade alloy steel, rigorously heat-treated to achieve specified tensile strengths (G80/G100). Resistant to deformation, истирание, и усталость.

• Повышенная безопасность: Designed and manufactured in strict compliance with international safety standards (Iso 4778, Iso 7592, ASME B30.9, В 818-4, и т. д.). Critical for protecting personnel and loads.

• Точное производство: State-of-the-art production processes ensure consistent link dimensions, smooth surfaces, and reliable weld integrity. This minimizes internal stress points and wear.

• Строгий контроль качества: Every batch undergoes stringent testing, включая:

  • Контрольное нагрузочное тестирование
  • Break Load Testing (destructive on samples)
  • Проверка размеров
  • Визуальный осмотр
  • Неразрушающее тестирование (Непрерывный) например, магнитопорошковый контроль (MPI) as required.

• Прослеживаемость: Each chain and hook is clearly marked with its Working Load Limit (Wll), оценка (НАПРИМЕР., G80), manufacturer ID (Вейхха), and often a unique serial/batch number for full traceability.

• Универсальность: Suitable for a vast array of applications across industries, from general manufacturing and warehousing to construction, добыча полезных ископаемых, судостроение, и тяжелая техника.
