A crane is a mechanical lifting device, that is often used for lifting heavy loads for industrial or construction purposes. The two types of cranes are the mobile cranes and the fixed crane. The mobile crane moveable from one place to another. Fixed cranes are only in one position but carry heavier loads, are more stable and can reach higher 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 can carry heavy loads and move from one position 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. Another type of cranes is the Jib crane. Moveable hoist available in Jib cranes are supported by the 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. 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. Somethings that needs the necessity to consider is the kind of foundation and structural support that are available to mount the jib upon. The cost of the crane, the installation cost and the maintenance cost are also important to put into consideration.
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. The crane that have many components are capable of working in much more environments. It should be a mandatory to put into consideration the mechanical and electrical components. You should learn about the motor controls and the operator controls for the right crane to be bought. 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.
