A crane is a robotic device that is used to carry heavy materials either in an industry of a site of construction. The mobile crane and the fixed crane are the general types of cranes. The mobile crane is flexible and can move in different positions. Fixed cranes are only in one position but carry heavier loads, are more stable and can reach higher heights.
There are various examples of cranes which a being used in the field of construction and harbors. Gantry is a type of cranes that have many extensive uses. There are different types of gantry cranes that are developed for different uses. There are gantry that is used to carry small loads, these are the lightweights and others are used to carry heavy materials.
The gantry crane is one example of the most flexible and has essential parts of any material handling process. It can carry heavy loads and move from one position to another. Due to their design of their units they can lift and move materials to where they are required. The another example of cranes is the Jib crane. With Jib cranes the moveable hoist is supported by a horizontal beam. They can move up to five tons at once and can extend to 20 feet of floor space. Two types of Jib cranes are the freestanding Jib cranes, and the wall mounted Jib cranes.
Selecting a jib crane involves numerous considerations. You should look at the needs of the crane and all application that the crane will be used for and whether it needs to move along. A part of this requires deciding on the how tall should the crane reach and the kind of the height it will reach. It is necessary to put in consideration the foundation and structural support that are readily available to put the jib crane on. The cost of the crane, the installation cost and the maintenance cost are also important to put into consideration.
Before you buy a crane some of the things you need to look upon include; the cost, the application of the crane, maintenance cost, lifting capacity, speeds and distances, usage limit and the components of the crane. Cranes with different components are suitable for various working environments. So, you must take into account the components like mechanical components and electrical components. Besides, you must also learn about the motor controls and operator controls to ensure that the right crane is purchased. Cranes are controlled in various ways such as the radio control, infrared control or in-built control station using a push button pendant of by an operator sitting in the cab of a vehicle.
