Material handling is a vital part of every industrial system. As a result, the materials management sector is active, competitive, and aggressive.
A crane is a piece of mechanical lifting equipment with rope drums, ropes, and sheaves for raising and lowering items as well as horizontal movement.
It employs basic devices to provide mechanical advantage, capable of moving objects beyond human capacity. Explosion-proof Overhead cranes are extensively utilized in the transportation industry, construction, and industrial sectors.
Heavy goods are handled and transferred from one location to another using overhead cranes. For raising the safe working weight, electric overhead travelling cranes have been widely utilized in various sectors.
Overhead crane types:
In industries, several kinds of overhead cranes are employed, with so many of them being extremely specialized. Therefore, single girder cranes, twin girder cranes, gantry cranes, and monorails are all examples of overhead cranes.
Single Girder Crane
A single bridges girder is supported by three end trucks by the crane. It has a trolleys hoisting system that operates on the bridge’s girder’s bottom flange.
Double Girder Crane:
Two bridge girders are supported by three end trucks by the crane (end carriages). The trolley travels along tracks on the bridges. Electric overhead cranes, including double girders, are commonly employed in the industry.
Because then they can lift heavier weights with greater span than just about any other form of a crane. However, we are focusing on twin girder electric overhead cranes in this development.
The bridge for transporting the trollies or trolleys is solidly supported by three or more legs operating on dedicated rails or any other runways. The cranes are substantially the same as standard overhead cranes.
These “legs” link to end trucks that travel on a rail that is either integrated into or put on top of something like the floor. They are eliminating the need for sustaining runways and columns systems.
“Electric Overhead Traveling” is what the EOT in EOT Cranes refers to. Overhead cranes of this type are permanent and enable lateral forces in two planes. People can travel not only forwards and backwards but also down and up with weight. However, these cranes are ideal for use inside.
EOT cranes are used in manufacturing, assemblers, large warehouses, and mining companies, among other places. These cranes are an excellent investment since they require little management and are simple to use. They are qualified operators and frequently need to lift heavy loads. The sole exception is that they should not be employed in potentially explosive or corrosive settings.
HOT Cranes refers to Hoist One Track in this case. HOTs are a type of stable overhead crane that also allows for lateral mobility in two planes. They are less frequent than explosion-proof overhead cranes because they do not have as much mobility as EOT cranes.
They’re more often utilized for routine maintenance. They have an electrical pendant that may be used to control a hoist attached to the bridge. Therefore, they’re reduced and a great investment should your business requires a lot of repairs and maintenance.
The most prevalent versions on the marketplace are overhead bridges cranes. A bridges crane includes two above runway beams that have been connected to the building’s framework. This crane is available in singles as well as double girder variants. Therefore, a double girder bridges crane has about the same capacity as a single girder bridge crane. A double girder crane, on the other hand, can lift a weight higher than a single girder crane. However, a single girder is easier to create and less expensive than a much girder since it is basic.
The girder of a gantry crane stands on legs rather than being carried on a support column. The legs can be operated either underground or on top of the substrate. So because the girder does not need to link to a building’s support network, gantry cranes are appropriate for outdoor operation. A gantry is the type of system to use at shipyards whenever you require a crane.
A workstation crane is designed for usage in situations where space is limited. It’s a straightforward design that really can lift anything from 150 pounds to 2 tonnes. Overhead cranes for workplaces are ideal for repetitive tasks such as transporting packed boxes in a factory. Therefore, they’re made to be comfortable to use frequently. (Types of Overhead Cranes)
Material handling equipment includes overhead travelling cranes, gantry cranes, jib cranes, and railroad hoists. Explosion-proof overhead crane safety procedures of such cranes necessitate the knowledge and skill of the operators to prevent an accident. The end motive is to enhance awareness of the risks associated with lifting heavy objects and with providing fundamental understanding. Therefore, how to safely operate overhead travelling cranes, jib cranes, gantry cranes, and hoists.
