How Does A Crane Girder Work?

The crane girder is a steel beam that provides a platform for the crane to move. Hoist and cranes simplify industrial processes by making the movement of heavy stuff easier and girders play a significant role in such movements. The overhead cranes use one, two, and three crane girders depending on the type of installation. 

Single crane girder 

In single girder cranes, one crab girder comes into play. Single girder cranes can be used in the industries where there is no need for any transverse movement. The hoist moves along the length of the grider and can be used to lift and lower loads in the workspace. The girder stands upright and the crane moves along the beam. The single girder cranes come really handy in narrow spaces, where there is lesser room for movement. The cranes run on the bottom of the girder which can sometimes look as a disadvantage. Since the crab and hook are usually located under the girder, you might find the hook height less. 

Double or Bridged crane girder 

When you have better space and need something more flexible, double or bridge girder cranes fit your needs. The double girders offer flexible three-dimensional movement. Double girder installations offer movement along both length and breadth of the space covering much larger space. Thus, the load handling process becomes a lot more efficient. The crab girder can run on top of the support beams or between them which offers extended hook heights. With more hook and wider area coverage, the double girder or bridged cranes offer great flexibility.

Stress on the Crane Girders

Crane girders are used to handle a lot of weight and that’s why these are subject to a lot of pressure. The girders need to be well taken care of so that any accidents can be prevented and the girders last longer. The stress on the girders not just comes from the pressure exerted due to large weights, but the acceleration and braking of crabs also causes lateral stress on the girders. 

The best way to keep the crane girders working fine is providing them with enough support. Channels and flat plates across cross sessions and other places can prevent extreme stress and ensure the longevity of the girders. Also, the owner needs to keep inspecting the girders and all other parts of the crane from time to time as suggested by the seller. Make sure to purchase top rated crane girders only and tae care of them well. Replace, and repair them as per the instructions provided by the manufacturer to ensure safety of your workers. 

Finding high quality crane girders can be a little exhausting if you don’t have the required resources to track the right fit. Not only do you need to find out the right seller, but the right crane also. And this all can be done with just a single call. Book a consultation call with our experts and you will left with no doubts.

Mob Cranes

As the name suggests, the mobile cranes are those cranes that can be moved from one place to another. The mobile cranes are further divided into:

• Tire Mounted Cranes: These cranes are fitted with telescopic booms. These cranes are again divided into:
• Rough Terrain Cranes: This is a crane where the boom is mounted on the upper carriage and undercarriage on their four rubber tires. These cranes are designed for off-road pickups.
• All-Terrain Cranes: These cranes can be taken to the highways and they can comfortably run on uneven roads as well.

Tower Cranes

• Tower Cranes are fixed on a single foundation but they have the capacity to work on a larger radius.

Crane Erection at the Site

• Now that you know the types of cranes available in the market, let us tell you how these different cranes can be erected well.

Mobile Cranes

• One of the biggest advantages of working with mobile cranes is that they are not required to be erected at the site separately. However, the cranes above the weight of 100 tonnes have to be erected by removing their counterweights as they have to be taken to the crane separately.

Crawler Cranes

These cranes can be transported to the business site in a dismantled manner. The modern crawler cranes can be erected in the following ways:

• Self Assembly: There are certain crawler cranes that can assemble itself. This simply means that they can be assembled without any human intervention. They use the technique of self-assembly, but it is quite time-consuming.
• Erection with supporting crane: This calls for one of the most popular crane erection technique where one crane needs the support of other cranes for its assembly.

We hope that you are now clear with all the erection techniques for your cranes. For further specific details, you can get in touch with your crane manufacturer Ahmedabad. If you have any difficulty in erecting your crane, the team of Hoist and Crane will be there to help you.

Don’t know whom to talk? Krishna Cranes and Engineers can help.
Here are some of the industries that make use of EOT cranes:

Warehouses
Bulk material is loaded from industries and moved to warehouses. Now unloading and shifting of such tons of weight is not possible to be done manually. It’s not even safe plus the labourers can get strain and injuries while handling such load manually. So, the overhead cranes are used in warehouses to bring the load from the dock areas. Also, the load to be transferred further can also be handled with the help of an overhead crane.

Assembling industry
As we all know that parts of bigger machines are prepared separately and then, these are assembled to give a final look. Since the developing of parts is quite messy, it’s done at a place away from the assembling area. The parts are heavy, and it’s not easy for humans to bring them to the assembling area. Not only is it hard, but it also takes a lot of time. The productivity of the industry slows down and to prevent that, overhead cranes are best.

Transportation Industry
Transportation of even smaller goods can be robust when these are in bulk. Transportation of heavy items like machines is even more complicated. You need an overhead crane to put the things to be transported on rail cars or open trailers. Not only it will make the process fast, but you will find that the goods get transferred safely.

Storage Industry
There are several heavy items in storage places, and that need to be moved here and there continuously. Storage areas can have bulk paperwork, vehicles, machinery, and household appliances as well. Overhead cranes are quite helpful in such places as they help in the safe movement of heavy units.
Several other industries such as construction and chemical handling also make use of overhead cranes.

Qualities of a good quality EOT crane manufacturer

The superior EOT cranes should have functional capabilities such as robust and perfection in dimension. These characteristics have moved to select one who providing productive and well-operated hoist devices of several types.

Wheel Load Design Calculation of Jib, Double Girder, EOT Crane

The crane wheel load, usually referred to as maximum wheel load is the total load in pounds that any single crane wheel will see. The formula for determining…

MWL is Bridge weight / 2 + {Live load (crane capacity + hoist weight) x 15%impact*)/ Number of wheels on a single end truck.

For a top running 5-ton capacity crane, with a bridge weight of 8000 lbs. and a hoist that weights 900 lbs. with four wheels total:
8000/2 + (10000+9000 x 1.15)/2=12925 *15% impact for hoist speeds under 30 fpm in CMAA Class C Service

How is crane deflection measured?

Deflection is the measurement for the displaced structural element under load. In the case of overhead cranes, displacement of any member or part of crane is considered as deflection. The vertical and horizontal displacement can cause changes in the design of the crane and also impact the working of the device.

Let us discuss the different ways to calculate the vertical and horizontal deflections. Also, the various organizational specifications for different types of cranes are also explained.

VERTICAL DEFLECTION CRITERIA

Vertical deflection impacts the mast, columns, wall and all other parts that stands vertically. In vertical deflection criteria, the highest deflection ratio for lifting device is defined.

HORIZONTAL DEFLECTION CRITERIA

Horizontal Deflection impacts the horizontal parts of the image. Horizontal deflection is measured for workstation bridge cranes and workstation jib booms. Horizontal Deflection Criteria is the highest deflection ratio for runway or bridge crane kind of device.

What is the wheel load?

The amount of load carried out by a single wheel of the vehicle is wheel load. Each wheel gets some fraction of weight when we use a crane to lift and move the load. Though the wheels work mutually together, each wheel transmits its part to the road.

Each wheel can carry a specific amount of load, but dual wheel or dual tandem assembly can be used to carry more weight than a single wheel. Equivalent single wheel load of the dual wheel can generate the same amount of deflection, maximum stress, and contact pressure, etc. on road or track.

Boyd and foster method, also known as the semi-rational method can be used to find equal stress for ESWL (equivalent single wheel load).

What is the design wheel load?

The pavements and their failure are directly related to the design wheel load. Pavements fan fail due to several reasons like the amount of traffic, loading, structural models, material characterization, environment, etc. but wheel load is an important factor to determine the depth of road or track.

In general terms design load is a load that the system can not take and can not produce the expected result during that situation. It can be also defined as the system will fail in an unexpected case.

These kinds of situations occur because some time engineers fail to design a system that can handle unexpected loads.

What is the standard axle load?

Determining the wheel load or axle load of a single vehicle is easy task whereas determining the types of wheels loads is a difficult task. The wheel load determination is related to pavement design life.

The determination of types of wheel load is required to understand the damage to the pavement. The destruction of pavement is the primary concern that is caused by wheel load.

The most commonly used approach in this case is converting the pavement damage from single or dual wheels loads into a single load with the help of various magnitudes which is called “standard” or “equivalent” loads. At that time all the factors related to traffic are used under one term like equivalent single axle load.

What is point load of a crane?

Point loads occur when relatively high weights are concentrated on a small bearing area.

So; point load on a crane with hooks is a load that is not centered. If you try to pick something up with the end of the crane hook, the load is not centered and would be “point loaded”. This type of load will stress the crane cables. When the load falls off the hook-point, the crane cables react – and can break strands of the cable.

The crane cable consists of an inner cable and outer cables – so as a load is placed on the cable, it stretches. If this load suddenly shifts or falls, the cables retract quickly and can break. This is dangerous; as you may not notice the inner cable has broken (could be a small bulge in the cable). Using the crane with a broken cable can cause it to fail and drop the load.

A stable load is one in which the centre of gravity of the load is directly below the main hook and below the lowest point of attachment of the slings. The center of gravity of an object is that point at which the object will balance. The entire weight may be considered as concentrated at this point. A suspended object will always move so that the center of gravity is below the point of support. In order to make a level or stable lift, the crane or hook block must be directly above this point. Thus a load which is slung above and through the center of gravity will be stable and will not tend to topple or slide out of the slings.

Understanding Load Factors and Their Impact on EOT Crane Design

Electric Overhead Traveling (EOT) cranes are designed to safely and efficiently handle a specified weight limit. However, several load factors influence this capacity and ultimately impact the design of the EOT crane, including:

• Static Load (Dead Load): This is the weight of the crane itself, including the bridge structure, trolley, hoist, and end trucks.

• Dynamic Load (Live Load): This refers to the weight of the material being lifted by the crane.

• Impact Factor: Accounts for the dynamic forces exerted on the crane during operation, such as sudden starts, stops, and swaying of the load.

• Wheel Spacing: The distance between the wheels on the crane bridge and end trucks affects how the overall load is distributed.

Wheel Load Calculation:

The EOT crane wheel load calculation determines the amount of weight each wheel needs to support. This is crucial for ensuring the crane operates within its safe working limits and to design the runway and supporting structure capable of handling the forces exerted by the crane.

Impact on Design:

Understanding these load factors allows engineers to design EOT cranes with:

• Appropriate structural strength: The crane bridge, trolley, and end trucks must be robust enough to withstand the combined static and dynamic loads.are chosen to handle the calculated wheel load.

• Optimal wheel selection: Wheels with the proper capacity and diameter 

• Safe runway design: The runway structure needs to be designed to support the total weight of the crane and the calculated wheel loads.

By considering these load factors during the design phase, manufacturers can ensure EOT cranes are safe, reliable, and capable of handling the intended loads throughout their operational life.

Optimizing Your EOT Crane: Load Capacity Based on EOT Crane Specifications

Selecting an EOT crane with the right load capacity is crucial for maximizing the performance and lifespan of your equipment. Here’s a deeper dive into how EOT crane specifications influence load capacity:

• Bridge Construction:
  • Single-girder cranes are typically designed for lighter loads. They offer a more compact and cost-effective solution for applications where weight limitations are known.
  • Double-girder cranes provide superior stability and increased load capacity. They are ideal for heavier loads or situations requiring more frequent lifting cycles.

• Hoist Capacity:
  • The lifting capacity of the hoist directly contributes to the overall load capacity of the EOT crane. Choosing a hoist with a capacity exceeding your heaviest lifts ensures a safety margin and prevents overloading.

• Trolley Design:
  • The trolley, which carries the hoist, also has a specific load capacity rating. It’s essential to consider the combined capacity of the hoist and trolley when determining the overall lifting capability of your EOT crane.

Optimizing for Your Needs:

By carefully evaluating these specifications, you can select an EOT crane that perfectly aligns with your lifting requirements. Here’s how:

• Identify Your Heaviest Loads: Always choose a crane with a capacity exceeding the weight of your heaviest lifts. This ensures a safety buffer and prevents overloading, which can lead to equipment damage and potential safety hazards.

• Consider Future Requirements: If you anticipate handling heavier loads in the future, factor in potential growth needs when selecting your crane’s capacity. Purchasing a crane with some extra capacity can save you from needing to replace it sooner than expected.

Benefits of Choosing the Right Capacity:

Matching your EOT crane’s load capacity to your specific needs leads to several benefits:

• Safety: Choosing the right capacity prevents overloading and potential equipment failure, ensuring a safer work environment.

• Efficiency: A properly sized crane allows for smooth handling of your loads without compromising safety, leading to increased efficiency in your operations.

• Cost-Effectiveness: You avoid unnecessary investment in a crane with a higher capacity than required. This translates to long-term cost savings.

Get the Right EOT Crane for Your Needs: Choosing the Right Load Capacity

Selecting the right EOT crane for your needs goes beyond simply choosing the model with the highest lifting capacity. Here’s a breakdown of key factors to consider when making this critical decision:

• Identify Your Lifting Requirements: Carefully analyze the weight and dimensions of the heaviest loads you’ll be lifting. This helps determine the minimum load capacity your EOT crane needs.

• Evaluate Duty Cycle: Consider how frequently you’ll be using the crane. Light-duty applications may be suitable for a crane with a lower capacity, while heavy-duty operations require a more robust crane with a higher capacity for long-term durability.

• Workspace Limitations: Measure the available height and width in your workspace to ensure the chosen EOT crane can operate freely without clearance issues.

Beyond Capacity:

While load capacity is a crucial factor, it’s not the only consideration. Here are some additional points to keep in mind:

• Lift Height: Ensure the chosen EOT crane offers sufficient lift height to meet your needs.

• Span: The crane’s span needs to cover the entire designated lifting zone within your workspace.

• Brand Reputation: Opt for a reputable EOT crane manufacturer known for quality and reliable equipment.

Making the Right Choice:
