Cranes to ease the task of Material Handling at Warehouses
The scope of material handling is not as limited only to a single sphere, yet, it has many dimensions attached to it. It has also a wider amplification to its services apart from its movement of the services on the floor in form of lift trucks, conveyors and automatic guided vehicles. It is generally more useful to use up an entire space and stretch above floor. In the three dimensional space of warehouse, it is the cranes that play a very important role while lifting and moving goods above the floor and around.
Cranes in a Warehouse comes in a variety of numbers and in load capacities. They come in form of light weight cranes which are used on workstations to massive overhead cranes that can lift weight up to more than 100 tons. Whatever may be the make of the crane it is made up of three parts?
One is bridge that is formed from rails that carry a trolley or trolleys. As depending on the crane a bridge can be stationery as well as moving. The second component is trolley that moves on bridge and final and the third part is hoist that is used for lifting device on which load is hooked and moved hither and thither. Cranes can run manually as well as are driven by power.
There are many types of cranes available as according to the service they provide. Workstation cranes are used in limited space and are free standing cranes. There is further classification of cranes under workstation cranes into Gantry crane, Jib Crane, Articulating-arm jib crane, monorail. Other type of crane is overhead cranes than workstation cranes. Jib and workstation cranes are to lift load in smaller area where as bridge and gantry cranes are used for lifting weight over long distances. Bridge cranes are mounted on ceiling and can move in six directions with load up and down, forward and backward, and sideways in both directions. In most of the cases they are built at the very moment when a building structure is made and facility is constructed.
