A crane is a mechanical lifting device, that is often used for lifting heavy loads for industrial or construction purposes. The mobile crane and the fixed crane are the general types of cranes. The mobile crane moveable from one place to another. Fixed cranes exist in one position and carry more massive loads, they have high stability and can rise to high heights.
Some types of the cranes available are used in the construction site and another place like the harbors. Gantry is a type of cranes that have many extensive uses. Several types of gantry cranes are developed due to the different needs. There are gantry that is used to carry small loads, these are the lightweights and others are used to carry heavy materials.
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. Due to their design of their units they can lift and move materials to where they are required. The the second type of cranes is the Jib crane. In Jib cranes moveable hoist is given support by a horizontal beam. They can move up to five tons at once and can extend to 20 feet of floor space. There are types of Jib cranes that include; wall mounted jib cranes and the free-standing jib cranes.Examples of Jib cranes are the wall mounted jib cranes and the free-standing jib cranes.
There are several factors to look on when selecting jib cranes. 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. Deciding on the tallness of the crane and the height it needs to extend. It is also necessary to consider what type of foundation or structural support is available to mount the jib upon. The price of the crane is equally important in addition to the cost of maintenance.
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 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.
