What is an Overhead Crane?
What is an overhead crane? Definitions of overhead crane vary by country. In general, overhead crane is a type of lifting equipment that can move extremely heavy loads and objects from one location to another safely and accurately using the overhead crane space or clearance of a manufacturing plant. Due to the nature of lifting work, the overhead crane are precisely configured and designed to suit a specific form of load application. Overhead Bridge Cranes are available in a variety of sizes, types, shapes and configurations with different types of overhead crane components and crane parts.
The overhead cranes are used for loading and unloading, handling, lifting molds from molding machines or feeding raw materials. The two main reasons for installing an overhead crane are efficiency and safety. Overhead cranes can operate many times faster than floor or floor-mounted devices. In dangerous, dangerous and severe conditions, such as in the presence of heated metals, explosive or toxic materials, overhead cranes can move materials safely and at same to type to secure workers.
What are the main types of overhead cranes?
Overhead Cranes come in a variety of sizes and capacities, as well as configurations and functions, developed on the basisof the two main categories. Because of the numerous designs and options, selecting the right crane is a necessary process for you to buy the right overhead crane for your application. The correct crane and its specs may significantly boost production and efficiency while also streamlining operations.
Overhead Bridge Crane
What is a bridge crane ? A bridge crane is an lifting equipment which will enables you to lift and move heavy materials or loads from one location to another in a efficient, safe and precise manner. A bridge crane, sometimes called an overhead crane, is a type of crane with a movable bridge that runs on elevated beams suspended overhead . This allows a load to be moved in three axes to and from any point in the crane’s operating space. Generally, the overhead crane can be used together with types of lifting devices or below the hook devices, such as lifting crane, crane grab,electromagnetic chuck, or using two or three of them to fulfill different work with an overhead crane. The universal overhead cranes have a wide application ,which can be used either indoor or outdoor in various places such as warehouses, factories, workshops, wharves, open storage yards, and many other material handling occasions, etc.
Monorail Crane
A monorail crane is a common type of overhead crane for light duty material handling which is mainly consisted of the overhead crane components such as a single beam either straight or curved and a lifting hoist. As a substitute for conventional overhead cranes and conveyor belts, Overhead monorail cranes are frequently adopted in applications where repetitive loads handling from one place to another within a designated area. Due to the simple structure of monorail crane, they are very popular for light duty loads handling and highly cost-effective. Usually, the monorail cranes are also known as monorails.
Workstation Crane
Workstation Cranes are a type of bridge crane that is used for light to medium-duty production. They can lift up to two tons and are available in a variety of configurations to match any area. Workstation cranes are smaller and more compact than general use heavy duty overhead cranes, allowing them to be readily positioned under jib or other types of overhead cranes to provide a more efficient work cell.
The ergonomics of workstation cranes are crucial, as they eliminate the need to lift large goods or products. Workstation cranes boost worker morale, quality, productivity, and safety, among other things.

What are the uses of overhead cranes?
It can be risky and time-consuming to move bulky, heavy, and awkward goods through the aisles and floor of a manufacturing facility. When considering movement options, it is important to consider the available area as well as the feasibility of adding an overhead crane in your applications.
Warehousing
When considering the requirement for an overhead crane, the first industry that springs to mind is warehousing, where supplies, equipment, and materials are constantly transported, positioned, and prepared. The timely transportation of heavy items from storage to the shipping dock is a primary advantage of using an overhead crane in warehousing.
Assembly
Large-equipment assembly industries require a way to lift and move partial assemblies from one site to another for completion. Forklifts, AGVs, and other means of material handling are insufficient and unsafe, necessitating the deployment of an overhead crane. Assemblies can be easily shifted as part of the manufacturing process.
Transportation
The same rules apply to transportation as they do to warehousing, where big, bulky products must be loaded onto planes, trains, and trucks. Large goods can be readily stacked for delivery using overhead cranes. This is especially true in international commerce, where large containers and goods must be lowered into ship holds.
Equipment Repair
When a punch press or other production equipment needs to be repaired, overhead cranes aid in the process by gradually moving and arranging pieces for easy access. Heavy equipment can be moved from its permanent site to a repair shop and then returned using gantry and bridge cranes. Lifting machinery up and over other equipment to be placed at a repair station is made easier by overhead cranes.
Auto Industry
Material handling and the supply chain, as well as lifting and transport applications, are all served by overhead cranes in the car sector. Overhead cranes are used in press plant operations to carry and store dies and tools, as well as maintain lines stocked. Workers at assembly factories rely on overhead cranes to increase their productivity and eliminate the need to lift goods.
Steel
The ability to perform in hard conditions at rising temperatures with high grade dust and strong vibrations is the fundamental criteria for cranes used in the steel industry. Ladle cranes are strengthened and stabilized to ensure that the ladle is handled safely and efficiently. For the delivery of components such as molds for casting and the supply of casting pieces, double girder overhead cranes are used.
Overhead cranes are widely used in the steel industry for safety and efficiency. Tundish, slab, scrap, billet or ingot, coil, and foundry cranes, to name a few, are all types of ladle handling cranes.
Plastics
The ability to perform in hard conditions at rising temperatures with high grade dust and strong vibrations is the fundamental criteria for cranes used in the steel industry. Ladle cranes are strengthened and stabilized to ensure that the ladle is handled safely and efficiently. For the delivery of components such as molds for casting and the supply of casting pieces, double girder overhead cranes are used.
Shipbuilding
Due to the nature of the materials necessary to build a ship, shipbuilding, like the steel industry, makes considerable use of overhead cranes. jib crane , gantry crane, and overhead cranes are the three types of cranes most commonly employed in the business. A chain or wire rope hoist will be utilized, depending on the type of material to be moved.
Material handling throughout the assembly process is the primary role of overhead cranes in shipbuilding. Each phase of shipbuilding, including processing, assembly, fieldwork, launch, rigging, and delivery, requires the employment of an overhead crane. Steel plate hooks and various types of chain hoists with electric motors are included in shipbuilding overhead cranes that are specifically designed to match the space requirements.
Gas and Petroleum
Because of the flammability of gas and petroleum, overhead cranes must be built to prevent the substance from burning. They’re made of spark-resistant, explosion-proof materials. Designing cranes for offshore drilling locations is a difficulty for the oil and petroleum business. Initially, the business relied on land-based designs that were modified to match the specific circumstances.
Mining
Because of the harsh nature of the mining industry, the sorts of overhead cranes that can withstand the conditions are in high demand. For maintenance and service on underground mining equipment, the mining sector relies on overhead cranes. The corrosive climate of mining operations causes equipment to deteriorate quickly.
Cranes for mining are large, heavy-duty machines capable of transporting many tons of material and equipment. They’re made of metals that can withstand heat, dust, and moisture. Overhead cranes must be able to operate efficiently and continuously in adverse situations.
Paper
Because paper rolls are often destroyed by the slightest hit, the paper business requires high duty cranes that can handle materials with remarkable precision and gentleness. Paper is manufactured in incredibly large, heavy rolls that must be handled with care.
Cranes for the paper industry feature automated control systems that can be utilized for pulp production and paper manufacturing to protect workers. The crane’s speed must be carefully controlled for proper material handling, and it must be fitted with slings for loading and unloading paper scrolls.
Crane Bridge
The cross bridge of an overhead crane runs longitudinally alongside crane tracks or crane rails which are laid on runway beams over the square operating area. Crane Bridges are manufactured from steel plate or steel beam which are connected with end carriages or end girders kits to move on the runway.
Hoisting Trolley : Electric hoists, open winch,
The lifting trolley is consisted of the lifting mechanism which contains the overhead crane parts and components such as a brake, motor, reducer, drum, and set of pulleys. The motor drives a drum that rotates through the reducer to power the wire rope or chain that life up and down the load. And also the lifting trolley of an overhead crane can be grouped in the wire rope hoist trolley, electric chain hoist trolley, and processed open winch trolley which is usually used in heavy duty applications, such as in steel mills for hot ladle handling , etc.
Driving Mechanism: Motor, Reducer, Wheels & Brakes
The driving mechanism of overhead cranes can be grouped in two parts, one is for the long travelling of overhead crane and the other is for the crossing travelling of the lifting trolley. For different uses and applications, various types of motors, reducers, wheels and brakes are adopted.
Power Supply: Conductor Bar, Festoon System & Cable Reel
The power supply is a very important for the complete overhead crane system. There are mainly three types of power supplier system by using conductor bar, festoon system, and cable reels.
The major types of overhead cranes adopt electricity as the driveing power and there are all other types of power supply such as pneumatic power and hydraulic powers. As for the electric overhead crane, the supply supply systems are mainly consisted of the following crane parts and components such as, festoons cable, conductor bars, or reel cables to deliver power to the crane runway, bridge crane control and trolley and hoist.
Runway
Crane runways are the important crane travelling components and parts. Based on the crane applications conditions and types of overhead cranes, the most suitable crane runways will be selected among the top running runway structure , ceiling mounted run way , wall mounted runway, or free standing runway, etc.
