Three Types of Freestanding Jib Cranes

The freestanding jib cranes are engineered to function freestanding on a concrete foundation without the need for building support. It comes in three basic design styles, which are base plate mounted, foundation mounted, or sleeve insert mounted and can allow up to a 360o rotation. The standard capacities these designs are able to lift, lower and transfer are ½ up to 5 tons, generally, but they can also be specially made for larger ton capacity work with a possibility of up 15 tons.

Base Plated Mounted Jib Cranes are generally designed with a hexagonal base plate that is reinforced with six knee braces, equally spaced around the circumference of the mast. Typically, the base plate assembly is secured by anchor bolts to a reinforced concrete foundation, with the number of anchor bolts varying, depending on the capacity of the crane. These six bolts are used for columns that are less than 16″ in diameter and 12 bolts for columns 16″ in diameter and greater.

Foundation Mounted Jib Cranes utilizes a square steel plate, which is welded to the bottom of the column.The plate positions and levels the mast by anchoring it to the concrete footing. Then the second course of the concrete foundation, which will reinforce concrete to support the mast. This will make complete use of the work floor space and can be used in applying concrete where a base plate would be able to support floor activity.

Sleeve Insert Mounted Jib Cranes has a square steel plate which is welded to the bottom of the sleeve. This allows the mast to be relocated. The plate positions and levels the sleeve by anchoring it into the first application of concrete footing. The second course of a foundation is applied to reinforce the concrete supports to the sleeve. The mast is then placed into the sleeve where it is leveled by wedges and welded in place. Sleeve insert mounted cranes generally have the capability to cover a wide span in a work area and can handle floor activity very well.

Freestanding Jib Cranes Design

The freestanding jib cranes design, indoor/outdoor usability, and capability for up to 15-ton capacities of lifting, lowering and transferring materials and objects, makes it one of the most versatile cranes in jib crane designs. The jib crane will also, allows for electrified, motor driven, powered rotation through many collector ring assemblies. The boom or I-beam are designed to meet all specifications utilizing a low percentage of impact for hoist and trolley weight. The pipe mast or column is engineered to give the highest level of strength and minimum deflection to avoid bending, buckling, and crushing as well as the capability of becoming worn by the trunnion roller assembly. The top bearing assembly utilizes a tapered roller bearing provided with a grease fitting for proper lubrication. The bearings are designed for a 5000 hour + design life.

Conclusion

The freestanding jib cranes are more economical and some benefits to using the crane are independent head assembly installs separately for ease of installation. Also, the full supporting triangular base plates are used instead of struts to reduce the crane’s deflection and make steadying the loads easier.

What Determines Overhead Crane Prices

If you are purchasing an overhead crane for material handling purposes, there are many factors to consider. Generally, overhead crane prices are determined by various factors. However, much of it depends upon the crane supply and demand equation.  Following are some factors that influence the purchasing of a crane:

• Crane Machine Technical Specifications.
  5-ton crane price is obviously different with the price of a 2-ton crane. Prices vary according to specifications.
• Manufacturing costs
  With different economic backgrounds, the production cost of a crane in different countries is varied accordingly.
• Configurations of the crane that is the choice of the main components such as, gearboxes, drivers, and motors etc.
• Volume or the quantity of the cranes. Prices may lower if the order is placed with large quantity.

Overhead Crane Prices | Additional Variables

Basically, the prices are determined by its specifications such as its tonnage, span, lifting height, working hours, crane operations and few other parameters. The tonnage basically refers to the largest lifting ability of the crane, mainly the maximum load a crane can bear. Whereas the span is the both ends of the crane which situated on the tall concrete pillars. And the working level is determined by the working hours and working conditions.

Also while buying a cost effective crane, the price is not the only factor to be kept in mind. The reliability of the crane is also a major factor. A crane is a long term investment. And a problematic crane might cost you a lot of money for repairing and maintaining purposes. A problematic crane might also increase the break time of your operation.

A major factor which determines the crane price the cost of the transportation. The transportation may cost which may even be higher than the price of the crane itself. If for example, you are importing a crane machine from overseas, then you’ll have to deal with the customs clearance cost. Then other cost includes the crane installation, maintenance, and parts cost.  Since the crane is a special piece of equipment which requires frequent maintenance; hence the crane parts are taken into consideration for a longer time.

What You Need to Know about Material Handling Equipment

Material handling is the development, protection, storage and control of materials and items all through manufacturing, warehousing, distribution, consumption and disposal. As a procedure, material handling equipment incorporates an extensive variety of manual, semi-automated and computerized equipment and systems that support logistics and make the work supply chain activities. Like other manufacturing industries, producers of material handling equipment (lift trucks, transports, automated storage and recovery systems, order picking equipment, overhead cranes, so on.) had it entirely rough during the recession. You have to look for an accomplice, not a seller. You have to pick a material handling partner who will listen to your strategic objectives and long-term objectives, not only fill an equipment order. A true accomplice will give solutions that are consistent with your entire mission.

Material Handling Equipment and Lift Trucks

“You may have an excessive number of lift trucks”. It might sound odd to hear that from a lift truck manufacturer but it may be valid. Fleet optimization can be a central point in whether an organization is operating cost-effectively. Work with a material handling partner to assess your lift truck fleet and decide how to keep running at most maximum uptime and effectiveness. Getting precise, real-time data is necessary for decision making about how to best manage with the lift truck fleet.

Optimizing your operations doesn’t need to mean accepting trade-offs. In many organizations, the purchasing and operations functions work hard to autonomously meet objectives to minimize costs and maximize output. By adopting a complete strategy to analyze asset purchases and moving product, organizations can better position themselves to lower expenses and upgrade proficiency simultaneously. To help organizations finish this errand and remain focused, some lift truck manufacturer is giving entire material handling solutions, besides just the lift truck.

New Technologies in Material Handling Equipment

Remember, don’t fear new technologies. Testing substitute energy and battery charging preferences are still a need for the industry. According to different researches, it shows higher efficiency and more manageable operations with these energy alternatives. For a few applications, there is an increasing interest for the potential for automated guided vehicles to lower labor costs and increase efficiency. You have to remain on top of the most recent innovations available and be open-minded about attempting another technology (perhaps a bridge crane). It might fundamentally enhance your operations.

A lift truck is more than a bit of capital equipment. In the lifecycle of a lift truck, the initial expense is just around 10% of its aggregate expense. The maintenance and operation (that includes parts and labor) represent the greater part of a lift truck’s cost. You have to carefully analyze and completely realize your lift truck fleet to capitalize on the efficiency of your assets. Understand how every truck’s efficiency should be utilized, how each truck is actually operated, how to take care of it and how to change if required.

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

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.
