Truck crane hook parameters

Weihua truck crane hooks need to take into account both lightweight and high strength. Parameters vary depending on model and load capacity. Common specifications are as follows:

Rated lifting capacity	Single hook load: 5~100 tons (common models 5~50 tons), Crane Double hook cooperative load: تا 200 تن (balance beam required)
Hook mouth size	Opening width (S-shaped hook): 50~300mm (for example, the opening of a 50-ton hook is about 200mm), Hook throat depth: ≥2 times the wire rope diameter
Hook body diameter	Match the load (for example, the diameter of the 20-ton hook is about 80~120mm)
مادی	Alloy steel (34CRMO4, 42CRMO, tensile strength ≥800MPa), Special environment: stainless steel (316L) or galvanized steel
وزن	5-ton hook: about 30~50kg, 50-ton hook: about 300~500kg (lightweight design)
Applicable wire rope diameter	12~60mm (needs to match pulley groove, groove diameter ≥1.1 times rope diameter)
Working temperature	Conventional type: -40℃~+200℃, High temperature resistant type: -20℃~+400℃ (special coating or alloy)

According to the rated lifting weight and type of operation, common truck crane hooks are divided into single hooks and double hooks. Truck crane hooks have different manufacturing processes and their load-bearing ranges are also different.

Weihua truck crane hook product features

Weihua truck crane hooks have the characteristics of high structural strength, lightweight, modular interface for quick installation, امنیت, دوام, and intelligence.

• 1. Material optimization: Using high-strength alloy steel (such as 42CrMo), the strength is improved through forging + heat treatment processes while reducing dead weight to adapt to the flexible movement needs of truck cranes.
• 2. Structural design: Streamlined hook body reduces stress concentration, fatigue life ≥10⁵ cycles (according to ISO 4301 استاندارد).
• 3. Modular interface: standardized shaft hole (Φ50~Φ150mm) or trapezoidal thread (Tr series), quickly connected to the crane boom.
• 4. Multi-scenario adaptation: Optional balancing beams, anti-decoupling devices or rotating joints can adapt to different loads such as containers, pipelines, and prefabricated parts.
• 5. Redundant design: double hook structure or reinforced single hook, safety factor ≥ 4 (according to GB/T 10051 استاندارد).
• 6. Surface treatment: hot-dip galvanizing (thickness ≥80μm) or Dacromet coating, salt spray corrosion resistance (C5 level, ایزو 12944 استاندارد).
• 7. Anti-sway control: Some models integrate damping devices to reduce hoisting swings (especially suitable for high-altitude precision operations).
• 8. Load monitoring: Built-in sensors monitor load weight and stress distribution in real time, and automatically alarm when overloaded.
• 9. Wireless communication: supports remote status feedback (such as crack warning, lubrication reminder).

Truck crane hook selection

How should customers choose Weihua truck crane hook types?

When selecting a crane hook, you need to comprehensively consider various parameters such as load type, working environment, وزن بالایی, etc. to select a suitable قلاب.

Bulk cargo (such as sand and gravel)	wide-mouth hook (≥200mm) + anti-chain device
Precision equipment	قلاب چرخشی + anti-swing design
Coastal/chemical areas	stainless steel or galvanized hooks
High temperature operation	heat-resistant steel + ceramic coating
Construction site hoisting	installation of prefabricated beams and steel frames (requires high-precision positioning)
Emergency rescue	rapid lifting of accident vehicles/equipment (emphasis on lightweight and rapid deployment)
Logistics loading and unloading	container and heavy machinery transfer (adapted to standard spreader interface)
