Hook suspensions: classification and features

Hook suspensions are a component of such an object in construction as a crane. This item is designed to capture this or that cargo. With the help of such a hook, the rope has the ability to connect with a load that must be lifted to a certain height. The so-called design of this hook is different, depending on the structure of the rope itself and the crane in particular. Later in the article we will take a closer look at crane hooks and their immediate features.

What is the pendant made of?

Crane hangers from different manufacturers incorporate different rope pulleys. Also, the composition of such a product includes blocks with so-called bearings and traverses. All these components are fixed with a metal plate. It is also worth noting that in such a suspension, the rotation of the hook should be free, for a smoother and more even lifting of the load. The mass of this product should be standard, because with the help of it the hook goes down, using only its owndirect weight.

The crane hanger has a one-horned hook. But it is worth noting that if the load to be lifted has a weight of 50 tons or more, then the two-horned hook is already used. This is necessary to increase the strength of the product. The hook has a special latch that acts as a safety catch and helps prevent the load from slipping out.

Classification of pendants

Construction specialists distinguish between hooks, and it goes like this:

• The first type is a difference depending on the lifting capacity of the crane itself.
• The second type differs in the number of so-called blocks.

It is also worth noting an additional classification, which directly depends on the location of the traverse. In this case, there are normal types of pendants and shortened ones.

Normal crane suspension differs from the second type in that its traverse is connected to direct blocks. As for the shortened suspension, it has a traverse, which is located on the axis of these blocks.

It is also worth noting that the second type of pendants in its composition has an exclusively even number of blocks. In this case, the maximum load on the hooks cannot exceed three tons.

Crane hook suspension is used on certain tower cranes that are specialized in building large houses.

Types of these pendants

Hook hangers also have their own types:

• single-axle hangers;
• biaxial;
• triaxial, as well as with application on block products.

Now in more detail about each species. It is not difficult to guess that the two-axle type of suspension has two axles in its composition. They are tightened by certain types of bolts. On this device, the bearing is arranged in a place that is protected from moisture and other external pests of its material. Due to this, its durability becomes longer. On this type of suspension, the load to be attached can rotate on a vertical axis. As we said earlier, each type of suspension has a so-called fuse.

The suspension, which already includes three axles, has two parts. But it is worth noting that the main part has an attachment in the form of additional material. This material incorporates two so-called cheeks. The block itself is attached between these cheeks.

Cargo pendants differ in their actual size.

Cargo suspensions

The hook suspension device can be quite diverse, which also distinguishes the power of this technique. The main difference lies in the mass that the hook can lift. The minimum weight is one ton and the maximum is fifty.

When a hook is created, its mass is made such that it contributes to lowering the hook down.

The simplest product in this case is a single-rope type. Such a device is used only for one rope, and the weight that can be lifted is minimal. The disadvantage of such a product, professionals consider the small weight of the rope and the hook itself in particular. The hook cannot lower the product on its own.

Features of this material

Requirements for hook suspensions are quite significant, because they are the main component of any crane. If their quality is not at the required level, then the cargo may fall, and the outcome of such events may be deplorable.

It is the hook type of suspension that is a mechanism that fixes the rope with the load. Only after proper fixation is the lifting of a certain material to a height.

Also involved in the lifting process is a rope made of steel. Lifting is carried out by winding this steel rope on a drum. The descent takes place in the opposite way.

Each suspension contains special blocks that rotate on a certain shaft, a hook and the so-called traverse. All these components are called the hook block.

As for the duration of the operation of each device, it depends on how such a product is used. Often, bypass hooks break in it. This is due to the increased friction force during operation.

Conclusions

So, the hook is a tool that grabs the material. Such a product is used on construction sites to help large cranes. It is also quite wide.applies to any mechanism that specializes in lifting a specific load.
