What are the types of crane hooks?

The crane hook is one of the core components of the lifting machinery. Its design and selection directly affect the safety and efficiency of the operation. This article will give you a detailed analysis of the common types of crane hooks and help you choose the most suitable hook according to your actual needs.

Two basic classification standards for crane hooks

Before understanding the specific categories, first grasp the two main classification dimensions:

• 1. According to structural form: single hook, double hook, combined hook.
• 2. According to functional characteristics: rotating hook, anti-detachment hook, special hook for special scenes.

Detailed explanation of 7 types of crane hooks

Types of crane hooks	Structural features	Advantages	Application
Single hook (single arm hook)	C-shaped opening design, one-sided force	Simple structure, light weight and broad vision	Light lifting operations (≤80 tons)
Crane double hook (double arm hook)	Symmetrical double hook design, balanced force	The load-bearing capacity is increased by 30%-50% and the stability is strong	Heavy metallurgy, port container lifting
Swivel crane  hooks (with bearing hook)	360° free rotation	Built-in ball bearing/slewing mechanism	Working conditions that require frequent adjustments to the direction of hanging objects
Crosby hook	Unique horn-shaped hook tip	Anti-detachment design, the wire rope is fixed more firmly	Shipbuilding, bridge construction
C-shaped hook (special for magnetic crane)	C-shaped opening with electromagnetic chuck	Supporting equipment: electromagnetic/permanent magnet lifter	Magnetic materials such as steel plates and steel coils
Electric rotating hook	Integrated motor drive system	Support wireless remote control and precise positioning	Automated production lines, smart warehousing
Laminated hook (forged hook)	Multi-layer steel plate riveting/high-strength alloy forging	Safety factor: up to 4:1 (industry standard is 3:1)	High temperature workshop, corrosive environment

How to choose the right crane hook? 3 selection principles

• 1. Matching load level: working load ≤ 80% of the rated load of the hook.
• 2. Adaptable material characteristics: Rotating hooks are selected for irregular goods, and liquid containers must be equipped with anti-sway devices.
• 3. Environmental adaptability: Stainless steel materials are preferred in humid environments, and heat-resistant alloy hooks are preferred in high-temperature scenes.

There are many types of crane hooks. When choosing a crane hook, you must choose a suitable crane hook based on various factors such as the working scenario, hoisting weight, and type of hoisting.
