What Are the Main Components of A Lorry Crane

18-Sep-2018 15:44 PM

Lorry crane is one of the essential machinery that is used on construction sites by different industries. A crane is a machine usually used to aid the construction process. This machine is joined with a mobile platform which is used for lifting and carrying heavy materials and objects. These machines are hydraulically operated and can quickly move heavy objects and materials. Below are the main components of a lorry crane that play an essential part in carrying heavy materials within a construction site:

1.Boom

A crane consists of a boom, and it is the most critical part of a lorry crane. It is the arm of a crane that lifts and lowers materials. The boom is situated behind the cabin of the operator, and it enables the crane to raise heavy materials to the required height. There are three types of booms that are used for different operations and purposes.

2. Jib

The Jib is another vital component of a crane – it is the extended part of the boom. The primary purpose of this component is to make the boom longer so that heavier materials can easily be lifted. Some of the cranes do not consist of a jib as these are designed to lift less amount of weight.

3. Rotex

It is the gear located below the cabin of the crane. This gear enables the cabin to rotate to a full 360 degrees, and it controls the boom with the help of a hydraulic motor.

4. Cabin

The cabin on the crane is joined on the deck, and it has a Rotex gear right beneath it. This gear helps the cabin in turning and rotating. This consists of the electrical control system for lorry crane operator to control the crane using the joystick and foot pedals.

5. Detachable Counterweights

The main purpose of detachable counterweights is to keep the crane balanced and prevent it from tumbling over. Professional operators use a specific formula to calculate the amount of weight that is required to keep crane stable. The amount of counterweight required depends on the load weight, the operational angle of the boom and radius of the boom.

6. Outriggers

The outrigger, similar to detachable counterweights helps the crane stay balanced during turning and other operations. Outriggers consist of three major parts; the leg otherwise also known as the beam, the foot or the pad. Sometimes they also consist of the float, and the main purpose of the float is to create a bigger base which helps in dispersing the force of the load.  

7. Steel Cable

Another important component of the crane is the steel cable. This cable is situated beside the boom and, the main purpose is to tie or secure the materials being lifted. There is a metal ball attached to the hook at the end of the cable. This metal ball helps in maintaining the balance of the crane when it is not carrying any material or any load.

These are some of the main components of a crane which enables it to lift heavy materials and work smoothly.
