Factory Crane Sale | Working Requirements

Working requirement, working class, and working speed are all related. A crane with a high class, frequent high efficiency, and can easily create fast speed, a working mechanism with a low class and by adjusting purpose can adopt low speed. A crane that will only be used for maintenance or equipment installation can choose a low speed. It also can choose to accept a dead speed, adjustable speed or double speed which includes high and low speed. Since working speed is close in line to the working room, a crane with a longer travel distance, high lifting height is acceptable for high speed. High speeds are not appropriate for cranes with a short travel distance. A crane with a lot of transporting work will tend to choose high speed. A crane for the purpose of maintenance and installation adopts speeds that are adaptable. Cranes with special functions should have a fast-down device for a crane with high lifting height should improve lifting speed and increase efficiency. To improve efficiency, crane precision is necessary.  The material needs to be durable and equipped with complete safety protection devices.

Industrial Cranes: A Crane For Every Purpose

Single Girder Cranes | Industrial Cranes | Industrial Crane Manufacturer

There are various types of industrial cranes used mainly for, but not limited to construction purposes. Cranes are engineered to carry extremely heavy loads and used generally for maintenance work, recovery, etc. A crane is a tower or derrick that is equipped with cables and pulleys that are used to lift and lower material. There are 11 industrial type cranes, that you will become more acquainted with reading this article:

Vehicle Mounted Crane

Vehicle mounted cranes are industrial cranes mounted on a vehicle for the purpose of loading and unloading that vehicle. The vehicles loading crane should be mounted on the specific vehicular type and models specified by the crane’s manufacturing company. Installing a crane inappropriately on a vehicle could lead to potential structural damage to the crane or vehicle or make the vehicle and crane combination unstable. Welding the crane to the vehicle chassis is unacceptable as it can damage the chassis and lead to languor failure of the connection.

Tower Crane

Tower cranes are used for lifting heavy building materials like concrete slabs, steel structures, bulk sand bags; machinery equipment like power generators, cement mixing machines; and other objects. Tower cranes are generally positioned at the top of buildings to handle heavy loads being lifted and lowered from the building. With an exact position on the building, this makes it much easier to import and export materials to and from the building. These cranes are built beyond a certain height for construction and will remain an integral part in architecting. They are very imported in aiding in the construction of the building and keep construction worker safe as well as city inhabitants.

Rough Terrain Crane

Specifically engineered for pickup and carrying operations, the rough terrain industrial crane is used for building bridges, operations in power and chemical plants and refineries and for wide-scale construction projects. A rough terrain crane is the subclass of a hydraulic crane, also it has the ability to perform the same essential functions. As a self-propelled crane mounted on an undercarriage with four rubber tires, rough terrain cranes are specifically designed to handle off-road and rough applications and surfaces.

Crawler Crane

In essence, a crawler crane is a machine with capable strength for handling extremely heavy loads and moving around with it. The different parts of the crane will be referred to as house, car body, side frames, boom, hoist, wire rope, and sheaves. Their main function for crawler cranes in the industry is for the heavy lifting of materials to depict those specific materials for transport from one area to another.

All-Terrain Crane

The all-terrain crane is considered the luxury version of a mobile hydraulic crane, being likened to driving a high standard luxury car on pavement. All terrain cranes can be considered a hybrid between a mobile truck crane and a rough terrain crane.

Railroad Crane

The rail mounted locomotive crane provides a highly dependable and cost effective approach to material handling or construction activities. Despite a simple lift, breakdown rescue missions, the duty of cycle material handling, or even pile driving, a locomotive crane has been engineered to do the job effectively.

Harbour Cranes

Considered new developmentally engineered cranes, harbor cranes are high praise as among the most powerful material handling cranes throughout the world. Their flexibility gives them an edge and advantage over most cranes and the harbor crane makes its effectiveness for all areas of application in the harbor and thereby guarantee the highest execution of effectiveness.

Floating Crane

A crane vessel is a ship with a crane specialized in lifting heavy loads generally at sea. The largest of floating crane vessels are used mainly for offshore construction. On a sheerleg crane, the crane is fixed giving it a disadvantage because it doesn’t have the ability to rotate, and the vessel, therefore, is maneuvered to position any loads into place.

Aerial Crane

An aerial crane or flying crane is a helicopter used to lift heavy loads.

Telescopic Crane

Telescopic cranes are another form of heavy industrial cranes employed to transport and maneuver objects from one place to another. Cranes like the telescopic cranes are often used for hauling operations but it is also known that these heavy cranes are very important when it comes to carrying out maneuvering operations in port areas as well. Telescopic cranes are mobile in the sense that they transport goods and items in a dependable manner. Also since telescopic cranes are well designed with height adjustments, when it comes to hauling and transferring the goods from one place to place, the problems related to height are completely obliterated.

Level Luffing Cranes

Level luffing cranes are used for freight loading and construction generally by mid-sized ships. They can be built for double link, single link, rope balance, and other courses. These industrial cranes are important now and in shaping our future as they will always be improved in engineering to build higher and heavier structures, lift and lower even heavier material loads and do just about any other job the crane can take on.

Single Girder vs. Double Girder Crane | Which Is Best For You?

Single Girder Crane | Single Girder Overhead Crane

Before you can decide between a single girder crane or a double girder crane, you need to know what they are all about. This guide will help explain what bridge cranes are and which ones are suited best for your use even if you are entirely new to the subject.

A bridge crane is more professionally known as an overhead crane. This type of crane is often used in an industrial environment where lifting of heavy objects is required. In an overhead crane you will see parallel runways that are attached to a travelling bridge spanning the entirety of the gap. A hoist is attached to the bridge and is the major lifting component of an overhead crane. The hoist is what hooks the freight and moves it along with the help of the bridge.

As per the Crane Manufacturers Association of America (CMAA) bridge cranes are manufactured with two designs. A single girder and a double girder known as 1 or 2 cross girders in crane manufacturers’ language. You have two main options to choose from when you go about buying a bridge crane; namely single girder or a double girder crane. What you need depends upon the particular need for which you are buying a crane in the first place. However consider that buying cranes is not an everyday business but in fact a once in a lifetime investment, you need to be very certain about the type of crane you purchase.

Both single girder and double girder cranes are equally strong, rigid and also durable. There are misconceptions about the single girder cranes being less strong and durable as compared to a double girder but that is certainly not the case. Both cranes have different functions and different needs that they serve. Below explained are two major differences between single girder and double girder cranes so that you can make an informed decision about which one will serve the best purpose to you.

  • A single girder crane is known for its lateral bracing which is absent in a double girder crane. Also a single girder crane has stronger cross girders allowing for better reinforcement in tasks where reinforcement is needed with a crane.
  • As compared to a single girder crane, a double girder crane has a much higher height of the hook. It is usually about 18-36 inches higher than a single girder crane. Greater hook height is needed when you need to lift things at a greater height from the floor. This is one of the major advantages that a double girder crane has over a single girder.
  • A double girder crane is able to provide a higher lift because its hoist is situated between the cross girder. A single girder crane has its hoist placed under the cross girder and thus cannot provide much height.

Another very specific and important difference between a single girder crane and a double girder crane is that of its price. Single girder cranes are more affordable as compared to a double girder crane. This is because a single girder crane has just one cross girder and the design of the trolley is simple as compared to the other. Also the freight for a single girder crane is lesser thus the low price.

Not all cranes are single girder cranes. Single girder cranes span about a 100 feet and have lifting capacities for weights up to 100 tons. As per CMAA and cost effective studies, single girder cranes are considered as per the table mentioned below:

Capacity (Tons) Maximum Span (Feet)
7.5 80
10 75
15 65
20 60
25 55
30 50
35 45

 

Usually double girder cranes that are available in the market have very hoist and its trolley on top of cross girders. There is a space for a trolley with low headroom to be created and situated between the cross girders. This low trolley will be very beneficial if the crane requires maximum hook height, if the cross girder and the hoist is situated at a maximum height above the floor and also when distance minimizing is needed between the runway beams.

Here is an overview of a single girder crane and a double girder crane which will allow you to make your choice easily:

Single Girder Crane

  • One girder/can only operate in single direction
  • The structure is small, single hoist, single girder, end girders, electrical controls, low height, light weight, small size, small wheels
  • Cable operation and also wireless remote control options
  • Effectively improves utilization of space
  • Low plant investment costs
  • High end braking system automatic with anti-dust device

Single girder cranes are best when you need to lift weight under about 50 tons and the span is less than 35m. There isn’t any special use or requirements for a single girder crane. If you don’t need wide leg width, a very high working speed along with lifting of heavy things on a frequent basis, a single girder crane would be best suited for your operations.

Double Girder Crane

Double girder cranes are known to be the most important equipment for the mechanization and automation of the production process in the modern industries. Double girder cranes come in very handy during production and transportation of heavy equipment and weight. The double girder crane is used widely for both indoor and outdoor industries. It is also heavily used in mining, railway transportation, steel industry, logistics, port terminal and a lot of other industries and departments.

Double girder cranes are ideal when frequent lifting of heavy loads is required and that too for longer hours. 8 hours being the minimum limit whereas more can be added as per need. A single girder crane is ideal for short operation times; 6 hours being the maximum limit.

The price difference between the two cranes is one of the most sensitive differences there can be. Double girders are more expensive because of their structure and mechanism but both cranes are designed to serve their individual purpose which is suited to the industry.

Just Exactly What Does a Factory Crane System Do?

Factory Crane System

Factories manufacture and produce large amounts of goods; this process includes the packaging and transporting of these goods around the factory. Workers alone are not capable of lifting these loads as it would require a lot of workers to lift a single load, hence the factory crane system. In addition to a large amount of manpower needed to get the job done, the safety of the workers and the goods are at risk, such manual handling can possibly damage the goods and affect the health of the workers.

Factory Crane System | Injury Reduction

About 10% of the major injuries in the workplace are caused by manual handling. Research suggests that repeated lifting of loads can cause musculoskeletal disorders. These are injuries that affect the movement of the human body and result in the inability to work. If factory workers develop musculoskeletal disorders, they are eligible to get work leave or compensation and this can have draining effects for the employers.

To avoid such problems, cranes are used. Cranes are machines used to reduce manual labor in factories. There are several types of factory cranes such as overhead cranes, jib cranes, gantry cranes and monorail cranes. All of these, however, have the same basic function – to provide safe and easy lifting and transporting of loads across the factory.

Cranes usually consist of a runway structure that can be set up around the factory. The load that needs to be transported is then either loaded or hoisted onto this runway and then moved to wherever it is needed. Overhead factory cranes can be automatic or controlled by remote control which means that they can be operated from a distance, reducing the chance of the workers getting hurt or the goods being damaged.

Conclusion

Therefore cranes are used to speed up processes in the factory, create a safer work environment, reduce the manpower needed and ensure safe transportation of goods.

The Remarkable Industrial Overhead Cranes

Industrial Overhead Crane

The industrial overhead cranes are commonly referred to as bridge cranes in different industries. They consist of a metallic hook, termed as the hoist, mounted on rollers or belts that travel on a bridge. Industrial overhead cranes are of several types based on how much capacity of load they are built to handle as well as in how many dimensions they are available to carry different loads. The overhead bridge crane is one of the most widely used types of industrial overhead crane. They are typically used because they provide a very time efficient method for transferring and maintenance applications which is a key part in the industrial world.

Origin of the Steam Industrial Overhead Cranes

A U.K. company was one of the many companies that introduced the first steam-powered crane ready for mass production. Further development in the mechanical industry led to England manufacturing the first electric overhead crane, which was used for hoisting and placing guns in London. The crane was functioning until 1980 after which it was displayed in one of Birmingham’s museum.

The overhead crane consists of a hoist that is moveable in all three axes. It is electrical powered and provides the employees or workers to move on a bridge that rests on top of the crane hence the name “Overhead bridge”. One of the most widely used industrial overhead cranes is called the gantry crane. It is mounted on the floor and moved through belted tracks or either through rollers. Based on the amount of usage and run-time, the Crane Manufacturers Association of America (CMAA) has classified overhead cranes into six classes, A to F, starting from infrequent usage to continuous and intense usage. Selection of different class of overhead cranes depends on several factors including installation costs, maintenance, and work-hour requirements.

Overhead Crane Inspections

Overhead cranes are inspected on a daily basis. The individual components of the crane are checked for irregularities such as a fault in the chain holding the hoist or the hoist itself, the belt on which the crane functions or the joints between the rollers, in case of a gantry crane. However, proper precautions are still taken to an extent that the machines are inspected from a distance rather than up close.

The Amazing Factory Bridge Crane | Under Running | Top Running

Factory Bridge Crane

An overhead crane or a bridge crane as it is more commonly known is typically used in industries and environments where lifting of heavy loads is needed frequently. An overhead crane or a factory bridge crane has parallel runways that are connected to a bridge that can move covering the entire area of the gap. There is a hoist that is attached to the bridge and it serves as the major component that lifts loads. The hoist hooks the load and then moves it to its destination with the help of a bridge.

Factory bridge cranes can be divided into categories as mentioned below:

Under Running or Top Running

These happen to be the primary configuration for bridge cranes. Under running cranes are also known as under hung. On a top running crane, the end of the truck is attached to the top of the beam runway. Similarly an under running crane has the truck attached to the lower flange of beam runway. Both of these configurations have their own advantages.

With an under running crane you can go for a better end function using the hoist. Using an under running crane the hoist can reach the far end of the truck or even the end of the beam runway when it is actually not possible to do so with a top running crane. Also under running cranes are very cost effective because they allow for multiple tasks. You can use the hoist and transfer it along interconnected bridges and monorails.

As far a top running crane is concerned, it has its best advantage in being able to lift very heavy loads, heavier than those a normal under running crane can lift. Also a top running crane has greater headroom as compared to an under running crane.

The other configuration dividing the bridge cranes is:

Single Girder or a Double Girder Crane | Factory Bridge Crane

Both of these are a type of factory bridge crane and are very strong, rigid and durable. Both cranes are equal and have specified operations for which they can be used. What one needs depends solely upon their factory requirements when looking for a factory bridge crane.

Single girder cranes are not expensive as double girder cranes and are used to lift loads that weigh about 50 tons and their transfer span is within 35m. Single girder crane does not require any special equipment or reinforcements. They are ideal for use if you do not need greater leg width, a much enhanced work speed and you do not require lifting loads heavier than 50 tons at a time.

Where mechanization, modernization and automation of factories are concerned, double girder factory bridge cranes are the most suited to the industry. Double girder cranes are very useful when you have to lift heavy loads, greater than 100 tons at a time. It serves well for both indoor and outdoor purposes and is widely used in the railway, transportation, mining, port terminal, logistics, iron and steel industries and a whole lot of departments and industries. Double girder cranes can work for longer duration of time as compared to a single girder crane.

What Can You Tell Me About an Overhead Factory Crane

Overhead Factory Crane

A factory crane used in factories is also called overhead crane, bridge crane or EOT crane. An overhead factory crane could be a general factory crane, European factory crane, metallurgical foundry crane, carrier beam overhead crane, explosion-proof overhead crane, electromagnetic overhead crane, power plant overhead crane, steel mill crane, grab crane, etc. A factory crane is a widely used overhead crane in general construction and production factory plants, warehouse, workshops, power plants, metal shop, steel mills, etc. mainly for material handling and lifting. It is the most utilized piece of equipment for lifting big things and transporting them to different spots. It utilizes one or more machines to make mechanical advantages and accordingly move weights past the typical capacity of a human. Cranes are ordinarily utilized in the vehicle business for the unloading and loading of cargo, in the development business for the development of materials and in the assembling business for the collecting of heavy gear.

Overhead Factory Crane | Utilized in So Many Industries

An overhead factory crane may be utilized as a part of industrial facilities and is likewise called overhead bridge crane or EOT crane. An overhead factory crane incorporates European factory crane, carrier beam overhead crane, metallurgical foundry crane, explosion-proof overhead crane, electromagnetic overhead crane, control plant overhead crane, and steel process crane, and so forth. It is broadly utilized, the overhead crane is a part of general development and generation factory facility plants, workshops, warehouse, control plants, metal shop, steel factories, and so on fundamentally for lifting and material handling. The crane should be erected on an unoccupied floor where no industrial nor construction work is to be carried out during erection. The size of the floor must ensure free and convenient handling of the crane during the erection period i.e. setting the crane in erecting position on the floor, turning the suspended crane etc. the most convenient place for erecting the crane is the space between the columns provided there are no horizontal bracings connecting the roof trusses. The roof trusses used for lifting the crane should be checked for stresses during erection with a dynamic factor.

Besides testing the rope & trusses for strength, they should be tested for stability under horizontal forces acting at right angle to the truss plane. The winches employed for lifting the crane should be equipped with ratchet stops. The wire rope employed for erection must have tags indicating wire breaking forces and should be free of defects, fractures, kinks etc. The minimum safer factor should be three. When hoisting the crane or its parts the following conditions should be kept in mind.

  • The angle of inclination of the slings should not be less than 45 degrees.
  • To prevent rupture of the rope due to sharp edges of lifted materials, wooden or metal lining should be used.
  • The number of clamps to be used for fastening the rope should be sufficient.

Also, ensure that the axes of the winch drum should be exactly at the right angle to rope direction.
