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 offers flexibility allowing it to move from location to another. Fixed cranes exist in one position and carry more massive loads, they have high stability and can rise to high 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. 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. 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. Moveable hoist available in Jib cranes are supported by the horizontal beam. They are capable of lifting five tons and move 20 feet up from the ground. 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.
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. Apparently, cost of the jib crane is important, but the cost of installation and maintenance must also be considered.
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 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.
