A crane is a robotic device that is used to carry heavy materials either in an industry of a site of construction. There are two types of a crane; the mobile crane and the fixed crane. The mobile crane offers flexibility allowing it to move from location to another. The fixed cranes are located in one station, are well balanced and extend to much more heights as compared to the mobile cranes.
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. 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. This is because of the design of the units, once items have been raised from the ground, getting them to where they are required. 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.
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. Part of this involves deciding how tall of a crane is needed, and how high the jib needs to extend. Somethings that needs the necessity to consider is the kind of foundation and structural support that are available to mount the jib upon. 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. The crane that have many components are capable of working in much more 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.
