What is a Crane?
A crane is a type of machine generally equipped with a hoist rope, wire ropes or chains and sheaves, that can be use both to lift, lower, and move materials horizontally from one spot to another.
How does a Crane work?
To create a mechanical advantage, the crane uses one or more simple machines to create a mechanical advantage, thus moving loads beyond the normal capacity of a human being.
What are the Types of Cranes? Where are they Applicable?
A “gantry crane” is a crane built atop a gantry (a structure straddling an object or workspace). Gantry cranes can be small shop cranes used, for example, to lift engines out of vehicles. They can also be enormous cranes that could lift some of the heaviest loads in the world. Referring to the empty space straddled by the gantry as “portal”, gantry cranes are also called “portal cranes”.
The variants of gantry cranes include ship-to-shore gantry cranes, full gantry cranes, rubber- tired gantry cranes and workstation gantry cranes.
A “hoist crane” is a crane use for lifting or lowering a load by means of a drum or lift-wheel around which a rope or chain wraps as the load is lifted. Hoist cranes can be manually operate, electrical or pneumatically driven and may use chain, fibre or wire rope to lift the object. The elevator is the most familiar form of hoist crane. The cabin of the elevator is raised or lowered by a hoist mechanism. Generally, most hoist cranes couple to their objects / loads using a lifting hook.
The variants of hoist cranes are wire rope hoist crane or chain cranes, construction cranes (temporary elevator) and mining hoist cranes.
A mobile crane is a cable-controlled crane mounted on crawlers, rubber-tyre carriers or a hydraulic-powered crane with a telescoping boom mounted on heavy lorries, or as self- propelled models. They have an advantage of easy transportation to the work site and use with different types of load and cargo with little or no setup or assembly required.
The types of mobile cranes are lorry-mounted cranes, crawler cranes, rough terrain cranes, floating cranes, all-terrain cranes, pick and carry cranes, side lifter cranes, carry deck crane, telescopic handler cranes, harbour cranes, railway cranes and aerial cranes (sky cranes).
Tower cranes are balance cranes that you often see at the construction sites where tall buildings are being built. Tower cranes are fixed to a sturdy concrete slab on the ground or to the side of a structure. At the top of the mast, tower cranes have a short horizontal jib (comprising of counter weighing concrete blocks and an operator cabin) and a long horizontal jib (the working arm) that suspends the load to and from the centre of the crane. The slewing unit at the top of the mast is the engine that enables the crane to rotate. Cranes are applicable in the air, rail, road and sea transport sectors to load and unload freight. Cranes are used in the construction industry to move materials. They are used in the manufacturing industry to assemble heavy equipment.
What are the Advantages of Cranes?
1. Cranes are an integral part of moving heavy and massive objects in various sectors such as transport, construction and more. It is safe to use cranes to lift or move heavy objects that are beyond human capacity.
2. Cranes can be used to access and work on objects that are several feet or metres high – such as electrical pylons, outer parts of high-rise buildings and more. They can also be used to lift and move vehicles damaged in road accidents.
3. In construction sites for tall buildings, tower cranes with long horizontal jibs can lift, move and relocate heavy objects and construction materials.
4. Mobile cranes such as cranes mounted on heavy lorries or crawlers can help in speedy construction of flyovers or elevated metro rail tracks in major cities.
5. Gantry cranes, capable of lifting the heaviest loads in the world, are used in shipyards, ports and railway yards to load and unload cargo.
