Types of Crane Hooks
26 May, 2020
Crane hooks are classified depending on their manufacturing materials as well as the intended usage and, (amongst other factors) according to this, some aspects are more important than others. Different types of crane hooks can be classified according to their shapes, method of manufacture, mode of operation or other unique characteristics.
They are made in a variety of styles to meet specific needs and they are rated for loads of specific type and size. To understand this deeply, we will focus on the main types of crane hooks available in the market and see which applications they are most suitable for.
Before we start though, is important to remember that crane hooks or lifting hooks are necessary in order to move different and many types of loads and that there are a lot of uses depending on the application the intended use is for.
A Quick Look at the Different Types of Crane Hooks
Crane hooks are available in a wide range of configurations based upon their size, their load capacity and their intended use. It should therefore come as no surprise that there are a number of crane hook types of choose from. These include:
- Single and double hooks
- Forging and laminated hooks
- Closed and semi-closed hooks
- Electric rotary hooks
Let us now take a look at each of these types in slightly greater detail.
Single Crane Hooks vs. Double Crane Hooks
This being said, when you’re looking to define crane hooks depending on their shape, you will usually be able to choose between single crane and double crane hooks. As the name suggests, the main difference between these two options is the number of hooks included, and there are different sub-types possible such as the C-hooks (which is essentially a single hook variant with a slightly different shape).
Single Crane Hooks
These type of crane hooks are the right choice if your machinery deals with loads of up to 75 tons; this lifting hook is very simple and easy to use no matter which variant you choose.
Double Crane Hooks
They are similar in conception, but their design provides superior bearing which is suitable for heavier loads of over 75 tons.
Forging Crane Hooks vs. Laminated Crane Hooks
When it comes to the manufacturing methods used to create crane hooks, there are two main styles available: forging crane hooks and laminated crane hooks. Each option offers particular benefits and drawbacks that must be kept in mind while deciding which is better suited for our specific requirements.
Forging Crane Hooks
These hooks are forged from a single piece of high quality steel with low carbon which is cooled slowly to ensure optimum stress resistance (usually ranging from 16Mn to 36MnSi). These hooks typically feature very simple manufacturing and are also very simple to use, since they’re made of a single piece, with installation being very straightforward.
Laminated Crane Hooks
They are a little more complex, and are comprised of several steel plates riveted together to ensure higher stress resistance and increased safety. These hooks are conceived in a way that allows the hook to keep working even if some of the individual crane hook parts are damaged. Laminated hooks are available as single hooks or double laminated hooks, and there are several models available to match different applications.

Closed Hooks vs. Semi-Closed Crane Hooks
If you’re concerned about having the right hook attachments, then you have to choose between closed and semi-closed crane hooks. These different types of hooks feature an attachment for added security for carrying heavy loads; as the name suggests, the attachment can be closed or semi-closed.
Closed Crane Hooks
The closed crane hooks attachments are somewhat harder to use and more time-consuming, but they offer the highest possible safety measures and load bearing potential.
Semi-Closed Crane Hooks
They aim to bridge the gap, as they offer increased security levels compared to standard lifting hooks, while being reasonably simpler to attach and dismount than closed hooks.
Electric Rotary Hooks
If you have a requirement for a state of the art crane hook that offers the best features as well as the highest convenience, you will likely have to choose between electric rotary hooks or other types of sophisticated crane hooks.
An electric rotary hook is a sophisticated piece of equipment that will improve the crane’s manoeuvrability and effectiveness when hauling containers. These hooks feature the ability to rotate while keeping a strong hold on the cargo, which means they can be extremely convenient and productive in situations that involve moving many containers around limited spaces.
