Crane Hook for Sale

Cranes are an essential tool in modern construction and manufacturing, and one of the most important parts of a crane is the hook.

The composition of a Crane Hook

The crane hook is composed of the hook itself, the hook lugs, the safety catch on the hook, the hook groove, the hook shaft and the pulley. The hook lug is the hook lug that connects the hook to the hook beam or hook rope. The safety snap ring is used to protect the hook from slipping or falling off. The hook groove ensures that the object being lifted is securely fixed to the hook. The hook shaft is the main axis of the hook, which connects the hook to the hook beam. Pulleys can be used to change the direction of the hook so that the object to be lifted can be moved to the desired position more easily.

Crane Hook Types

According to shape, it can be classified into single hook and double hook. The advantage of the single hook: easy to make and use, and applied to light capacity. The load capacity of the double hook is better and used in heavy capacity.
According to the production method, it can be classified into a forging hook and a chip hook (plate hook). A forging hook is used. Chip hook is combined with the steel plate and more safety than forging hook.

According to cross-section, it can be classified into roundness, squareness, trapezium, and T type. Among them, the cross-section of the T type is the most reasonable, but complicated technology; the cross-section of the trapezium is less reasonable than the T type but with simple technology and is widely used. The squareness cross-section is often used in chip hooks, while the roundness cross-section is often used in simple light crane hooks.
According to its mechanical capacity, it can be classified into M、P、(S)、T、(V) based on the yield point or yield strength of the material.

Crane Hook Material

The hook should have higher strength, plasticity, and toughness. adopt low-carbon steel and low-carbon alloy steel. For example, level M and P hook always adopt DG20Mn; level T, and M adopt DG34CrNiMo or DG30Cr2Ni2Mo. To avoid strain, adhesive, and brittle, ISO suggests the least content of Al is 0.02%. The material of the hook can take GB10051.1 "Crane Hook" for reference.

Crane Hook Group

Increasing the lifting capacity and reducing the demand for the wire rope's diameter, will make the hook and pulley block into one. So this is called the hook group. The large lifting appliance always uses a hook group. The hook group is divided into a long hook group and a short hook group. When the balanced pulley is installed on the long hook group, the hook group with a singular rate has a larger lifting capacity. Short hook group applied to double rate one and has a smaller capacity.

Safe Use of Crane Hook

When using crane hooks, the following safety rules must be followed:

Inspect the hook before use to ensure that it is not cracked, deformed or otherwise damaged.
Ensure that the working load of the hook does not exceed its rated load. The rated load of the hook should be clearly marked on the hook.
When using the hook, the correct type of hook must be used to suit the shape and size of the object being lifted.
After lifting the object, the hook and the safety catch must be checked for secureness to ensure that the lifted.

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.
