Cranes are widely used in industrial applications for various activities. Primarily they are used for the transportation of heavy goods and raw materials over uneven terrain, in a localized area. Probably one of the most common examples of a crane used in day to day life is the overhead crane. Cranes can be differentiated on the basis of: their load-bearing capabilities, the reach of the arm, the area covered by the arm and the industrial purpose for which the cranes are used.
Cranes generally operate on some form of pulley system which lets you lift heavy materials into the air or lower them to the ground. Construction cranes are usually driven by a human operator, but cranes that are operated by remote control and infrared or radio signals are also used. Cranes can place heavy materials quite accurately and because they are used for building and knocking down structures they need to be transported from site to site.
Cranes have been in existence in one form or another for centuries. There are different sizes and types of cranes which are made for specific jobs. Some other common types of industrial cranes include boom, tower, ship, mobile, gantry, crawler, floating and jib cranes. Some of these cranes can rotate 360 degrees, thus facilitating a wide coverage area. Because of their inherent nature to lift and shed heavy industrial loads, these cranes are prone to heavy wear and tear.
One of the most basic types of crane is a mobile crane. These consist of a boom which is mounted on a mobile platform. The mobile platform is generally a truck and mobile cranes are also known as truck cranes. The mobile platform allows the mobile crane to move from site to site with ease. Mobile cranes can also be fitted with specialized adapters and additions so they can perform a variety of tasks including demolition and earth moving.
Tower cranes are also commonly used in construction environments. This is a type of balance crane which is used in the building of tall structures. Tower cranes are generally set up within a shaft inside of a building which is converted to elevators when the building is finished.
For aquatic construction, the floating crane is most commonly used. These cranes are used to build bridges and ports and for ship loading and unloading and ship salvage. Floating cranes are mounted on a pontoon platform which lets you move them across the water to wherever they are needed.
To ensure a long lifespan, industrial equipment grade cranes are made highly durable and capable of withstanding rough conditions. Cranes are the preferred mode for lifting equipment because they are more flexible than their industrial counterparts such as jacks.
