Ways to Choose the Suitable Crane Accessories and Manufacturers
Choosing the most suitable crane wheels and crane hooks involves considering several factors such as load capacity, material type, environment, and application requirements.

The selection of the crane wheel should be based on its load capacity, durability, and ability to operate safely in the specific environment. When it comes to choosing a crane hook, important factors to consider include the weight capacity, shape, and size of the hook. The type of hook should be chosen based on the type of lifting required, such as single or double-hook, swivel or fixed-hook, or a hook with a latch.

Some Useful Knowledge of Crane Hooks
Classification of Crane Hooks The classification of crane hooks is very wide, generally including shackles, rings, piece hooks, forged hooks, rings, pear-shaped rings, combination rings, S-shape hooks, nose hooks, American hooks, horn hooks, eye-shaped sliding hook, ring screw with insurance card, chain shackle, etc. Now we will mainly introduce the following three types: 1. Chip hook There are two types of piece hooks: single hook and double hook, which are generally riveted with multiple overlapping pieces of C3 and 16Mn steel plates. The hook has the advantages of simple structure, reliable operation and convenient maintenance. Single hooks are mostly used on foundry cranes, and double hooks are mostly used on general-purpose cranes over 100 tons. 2. Forged hook Forged hooks are divided into two types: single hook and double hook. It is generally forged with 20, 20MnSi steel as a whole. Because the single hook is eccentric, the force is not as favorable as the symmetrical force of the double hook, so the small and medium tonnage cranes below 75 tons use a single hook, and the large tonnage cranes above 75 tons use a double hook. This kind of hook is widely used and has formed a series. When...
