A crane is a mechanical lifting device, that is often used for lifting heavy loads for industrial or construction purposes. There are two types of a crane; the mobile crane and the fixed crane. 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. They are a whole range of different gantry crane that has been developed for entirely different purposes. 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 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. Another type of cranes is the Jib crane. With Jib cranes the moveable hoist is supported by a horizontal beam. They can carry up to five tons and can stretch until 20 feet from the floor. 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. It is a must to check all the uses of the crane and what to be applied application are there and if mobility is required. Part of this involves deciding how tall of a crane is needed, and how high the jib 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.
You need to consider when purchasing a crane include; the cost, the use of the crane, the maintenance cost, lifting capacity, speeds and distances, usage limit and the components of the crane. Cranes which have several components have the ability to work in different environments. It is a must to take account of the components which include the mechanical and electrical components. Besides, you must also learn about the motor controls and operator controls to ensure that the right crane is purchased. Cranes can be controlled in several ways that include radio control, infrared control or built-in control station using a push button pendant of by an operator sitting in the cab of a car.
