Lifting tongs design

Lifting tongs design - Crosby Airpes

Have you ever wondered how we approach our lifting tongs design? Each type of lifting equipment must fulfill specific needs that we must consider when manufacturing them. 

Get to know the details behind the design of lifting tongs. Enjoy!

Design is vital for weight lifting equipment performance

Crosby Airpes’ lifting tongs designs are engineered to safely grab and lift various materials and objects from existing crane configurations. Lifting tongs have multiple applications, whether generic or specific jobs. 

The two types of Lifting Tongs Design

Each client has different needs, infrastructures, and work methodologies, and therefore we must adapt each lifting tong design to the work that the tong must perform.

We must also opt for one type of grip or another, depending on the type of object to lift.

In general, there are two types of lifting clamps:

  1. The lifting clamps for coils
  2. The scissor lifting tongs

In the case of these second ones, the design can change substantially from one product to another. Let’s see some of the different lifting tongs we design in Crosby Airpes.

Coil Lifting Tongs

Coil lifting tongs are lifting tongs designed with a mechanized opening to handle different types of material coils. They are also called vertical coil tongs.

Scissor or pressure lifting tongs

The scissor lifting tongs close the load by applying pressure. The type and shape of the clamp can be different depending on the use we are going to give to the tong.

Some Scissor Lifting Tongs Predesigns

Crosby Airpes’ scissors lifting tongs go through a previous design process. All the critical variables are considered so that the machine’s performance is the most suitable and adapted to each client.

Sub-types of scissor lifting tongs

The scissor lifting tongs can be personalized in many ways. The following are the most common examples of scissor lifting tongs designs:

Rounded Closure

Perfect for handling pipes or materials with rounded profiles, such as logs.

Lateral closure

The lateral pressure of the clamp holds the load. This type of scissor lifting tongs is used for lifting plates, bars, and beams of steel and other materials.

Electric/hydraulic closure

The clamps are closed mechanically, either electrically or electrically/hydraulically.

Scalable designs for lifting tongs

Crosby Airpes can scale the lifting capacity of any lifting tongs design. The only limit is the lifting capacity of the crane where the tong will be installed and other factors such as the headroom in the case of the clamp working in indoor spaces.

We can design lifting clamps with the capacity to lift small weights such as several tons to scissor clamps that allow handling up to more than 100 tons of material in a single lift.

Another great advantage of the lifting tongs is that being a relatively simple mechanism, they require less maintenance than other products and can work in environments with dust, humidity, and/or high temperatures without a problem.

Crosby Airpes can design lifting tongs adapted to any crane and desired configuration.
