What Is Crane Hook？

A crane hook is a key component in a crane used to attach and lift heavy loads. It is a curved metal component, usually with a curved end, that is used to suspend, secure or lift loads. The design and size of the hook varies depending on the application and lifting requirements.

Hook set is one of the most widely used lifting devices in cranes, it consists of hook head, hook nut, thrust bearing, hook beam, pulley, pulley bearing, pulley lifting plate, etc.

Grab Hook Types

By shape: There are single hooks, double hooks, C-shaped hooks, piece hooks and other types of hooks.

Single hook is simple to manufacture, easy to use, mostly used for cranes with small and medium lifting capacity below 75t.
Double hooks (also called anchor hooks, mountain hooks) force conditions are better, the hook material can be fully utilised, used for lifting capacity of the crane.
C-Hook is a specialised tool for handling cylindrical objects such as coils or pipes. Its unique shape resembles the letter C and holds these objects securely in place.The arm of the C-Hook supports the cylindrical load, preventing it from slipping or moving during lifting.C-Hooks are commonly used in industries that handle cylindrical materials, including the steel, paper and textile industries.
Sheet hooks are made of several pieces of cut and shaped steel plates riveted together, individual plate cracks will not cause damage to the entire hook, safety is better, mostly used for large lifting capacity or lifting steel bucket cranes.

By manufacturing method: Hooks include forged hooks and sheet hooks (plate hooks).

How to Choose a Suitable Crane Hook？

Determine the Load Requirements:
Identify the maximum weight of the loads you intend to lift. This includes both the weight of the load itself and any additional equipment, such as rigging, slings, and spreader bars. Make sure you account for potential future requirements as well.
Understand Hook Types:
Familiarize yourself with different types of crane hooks. There are single hooks, double hooks, and special-purpose hooks. Each type has its own advantages and applications. For instance, double hooks distribute the load more evenly, while special-purpose hooks are designed for specific tasks like grabbing or handling coils.
Calculate Load Weight Distribution:
Consider the load's weight distribution. If the load is long or unevenly balanced, it might affect the choice of hook type and size. Calculating the load's center of gravity will help in determining the appropriate hook design.
Consider Safety Factors:
Factor in safety margins when selecting a hook. Industry standards often recommend a safety factor of at least 4:1 for static loads and 5:1 for dynamic loads. This means the hook's SWL should be at least four to five times the actual load weight.
Environmental Conditions:
Consider the environment in which the crane will operate. Factors like temperature, corrosion, and exposure to chemicals can impact the material choice and coating of the hook.

Safety Matters of Crane Hooks

Inspection: Regular inspection of crane hooks is essential. Inspect hooks before each use and conduct more detailed inspections on a scheduled basis. Look for signs of wear, deformation, cracks, or corrosion. If any issues are found, the hook should be taken out of service until it is repaired or replaced.
Load Limits: Crane hooks are designed to handle specific load capacities. Exceeding these limits can result in hook failure or damage. Ensure that the load being lifted is within the rated capacity of the hook and the crane.
Proper Rigging: Correct rigging techniques are crucial for load stability and safety. Use appropriate slings, chains, and attachments. Ensure that the load is evenly distributed on the hook and that the rigging is secure.
Latch or Safety Latch: Many crane hooks are equipped with safety latches or latches that prevent the load from accidentally slipping off the hook. Always ensure that the latch is in proper working condition and engaged before lifting.
Maintenance: Regular maintenance of crane hooks and associated equipment is essential. Lubricate moving parts as needed and replace worn or damaged components promptly.

Always follow the manufacturer's guidelines and industry standards when it comes to crane hook safety. Regular training, proper usage, and adherence to safety protocols are critical to preventing accidents and ensuring the well-being of workers and equipment.

Why Custom a Crane Solution?

At Yuantai, we know that there is no "one size fits all" in the lifting field. Universal cranes are suitable for general factories, warehouses, etc. Besides, different applications have different needs for cranes. For example, steel industries often lift steel plates, so need electromagnetic cranes. Ports and docks often need to load ore, gravel, and other bulk goods, so need to grab bucket cranes. Chemical dangerous places often need to carry flammable and explosive materials, so need explosion proof cranes.

So, we provide customized cranes according to the special needs of our customers. Custom crane solutions offer many benefits in a variety of applications：

Improve efficiency: Cranes can use automatic controls, and special accessories to improve efficiency.
Break space constraints: In limited spaces, standard cranes may not fit due to their size. Custom cranes can be designed as compact or lightweight cranes.
Cost savings: Customized cranes can lead to long-term cost savings. Customized crane solutions ensure crane's performance is all necessary for your business.
