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 offers flexibility allowing it to move from location to another. 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. The gantry cranes are one of the enormous cranes used. Several types of gantry cranes are developed due to the different needs. From lightweights that are useful for raising small items onto a workbench, through to fully integrated gantry cranes.
One of the most flexible with very important parts for handling any material is the gantry crane. It offers the ability to lift massive weights and move them quickly from one area to another. This is enabled by its design, immediately items have been raised from the floor and moving them to where they are needed. The the second type 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.
There are several factors to look on when selecting jib cranes. One must look at what needs the crane will be filling, what applications will be applied to the crane, and if mobility is essential. Part of this involves deciding how tall of a crane is needed, and how high the jib needs to extend. It is necessary to put in consideration the foundation and structural support that are readily available to put the jib crane on. Apparently, cost of the jib crane is important, but the cost of installation and maintenance must also be considered.
When purchasing a crane put in mind the following; 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. It is a must to take account of the components which include the mechanical and electrical components. Also, you ought to get the knowledge of the motor controls and operator controls to ensure the best crane is purchased. Cranes may be controlled by methods such as radio control, infrared control or a built-in control station using push button pendant or by an operator sitting in the cab of the vehicle.
