Are you thinking about using cranes in your construction activities? If yes, then you should do some thinking about the various types of cranes available in the market. In addition to this, you also have to know about the different operating procedures of these machines. Moreover, you must have a clear idea about the maintenance requirements and the power supply to run cranes efficiently. Thus, this article will help you understand all these things.
DescriptionA crane is simply a device, usually equipped with a fixed hoist rope, hooks, chain or cables, and shears, which is used to move and lift objects vertically and horizontally. In fact, it can carry heavier loads than a standard forklift. Moreover, it is primarily used to lift heavy items and transport them from one place to another. Overhead cranes are basically used to hoist certain kinds of items such as bricks, logs, crushed stones, etc., while overhead cranes are generally used to move and lift heavy loads such as bridges, clogs, and piles of rocks. Thus, these are some of the common functions of an overhead crane:
Operation The operation of a crane can be explained in different ways. The most common method is known as the mechanical operation which uses cranes to lift an object vertically and move it in a new location. Another method is known as the electrical operation, which makes use of electric motors, generators, etc. to lift heavy equipment and move it from one place to another. Yet another type is known as the pneumatic operation which makes use of compressed air to move any kind of load.
Maintenance In order to keep cranes in good working condition, the operator has to perform a number of activities. The most important activity is to lubricate the various moving parts of the crane so that they function properly and do not give rise to any problems. The other thing to bear in mind is to check the load bearing capacity of the crane. This is very crucial because if a crane has an inadequate load bearing capacity, it may prove to be very risky for the persons operating it.
There are different types of mobile gantry crane available in the market. The most popular ones are the screw threads, boom cranes, pneumatic jib cranes, hammerhead cranes, wire mesh, self-rise jib cranes, and retractable cranes. All these types of cranes are used for different purposes. For instance, the screw threads crane is used for placing the foundation of buildings and for lifting objects. The pneumatic jib crane and the wire mesh crane are used to place wires and cables on the ground and for lifting lightweight objects. Finally, the hammerhead and self-rise jib cranes are used to move heavy objects and transfer them to higher positions.
In addition, cranes are also mounted on trucks and other such vehicles. The most commonly used cranes are the pole-mounted and the wheel-mounted cranes. The pole-mounted cranes are widely used in places where there are uneven or sloping surfaces. The wheel-mounted cranes are widely used for setting up various types of tents, barns, and large buildings. On the other hand, the best thing about the gantry crane is that it provides a very strong support to the heavier loads and are highly portable.
