Define your crane requirements

First of all before approaching crane manufacturers it is important to define and document your requirements for the crane. The more carefully you consider and understand what you need the likelier you are to buy it. We have summarised some aspects to consider below:

Longevity &#; Think about how long you intend to keep the crane, e.g. 5 to 10 years (maybe even longer)

Budget &#; Calculate a budget and the capital outlay and also the amount of depreciation to charge to P&L each year

Need for mobility &#; Is there a need for the crane to be moved? Will the crane be used indoors only, outdoors only or maybe both?

Building restrictions &#; Does your building impose any restrictions, e.g. are the dimensions of the building adequate (width, height and length). Any obstructions should be identified; these could include overhead limitations, columns and walls. If 360 degree movement is important, will this be available? Buy a crane, which complies with your building restrictions or possibly consider building alterations work.

Building environment &#; Will the building temperature be OK, i.e. are there any extremes of heat (e.g. furnace) or cold (e.g. refrigeration). Is the building prone to contaminants &#; things like grease, shavings from metal and wood, airborne particulates, etc.

Crane usage

It&#;s also important to consider early on exactly how the crane will be used:

Usage &#; Will the crane be used daily, weekly, monthly or less frequently?

Portability &#; Do you need to use the crane in multiple locations? consider a mobile gantry crane.

Likely loads &#; What are the loads likely to be? Mainly small loads, a mix or frequently heavy loads? Try to calculate your maximum load and buy a crane which comfortably exceeds this load lifting capability.

Terrain &#; Is the terrain rough or smooth (particularly for outdoor use)?

Specialist tasks &#; If any specialist lifting tasks are required make sure these are understood and discussed with the supplier. Specialist tasks can often depend on the type of materials being lifted.

Crane Features to consider

Next document a list of features you require from the crane, this will include:

Power type &#; Is a fuel powered (LPG, diesel or petrol) or electric crane preferred, or maybe a crane with both?

Capacity &#; A very important factor to establish is the maximum capacity the crane will be subject to lifting? Include in this weight accessories like hooks and slings. The crane purchased should include load limiters wherever possible

Any special requirements &#; Are there any special or unusual needs?

Technology &#; What technology is desired? This could include WiFi / internet connection capability, LCD screens (including high resolution), remote controls and safety features (e.g. indicators)

Type of control &#; Is control to be through pendant or radio remote?

Manual/motor &#; Is a manual or motorised crane preferred?

Working through the above will have implications on the type of crane purchased, e.g. an overhead crane, jib crane, etc.

Calculate the Total Cost of Ownership (TCO)

The TCO is important. Calculate this over the term you expect to keep the crane, which you will have considered previously. Although important the purchase price is not the &#;be all and end all&#; and may only be a small proportion of the lifetime costs. Also calculate servicing, repair and running costs as well as the need to train staff. Where building alterations are required include these too.

Crane repairs

The ability to service and repair the crane over the lifetime of its use is critical. Always ask the manufacturer if parts will be readily available over a 5 to 10 year period. Also investigate how convenient/easy it is to maintain the crane (e.g. lubrication); can much of the basic maintenance be through in-house staff with only occasional use of external expertise? Crane services including Annual inspections are imperative so ask your supplier if they offer this service.

Crane Warranties and certifications

Paperwork to back up the crane is always desired. Always buy a crane which is CE certified (for EU purchases), ISO accreditation is very positive when evaluating a crane manufacturer. As a minimum seek a 12-month warranty and inspect what is included within the warranty.

The importance of after sales Crane support

A crane is a long-term purchase and therefore long-term after sales support will be needed. The after sales support available will be a buying consideration. Work with a supplier who you feel you can trust, ideally one who you can read references from. Calculate the cost of support and look for any hidden extras. Crane downtime can be very costly so always understand how quickly a crane can be repaired and would a loan crane be available in the interim? The support of a dedicated Account Manager could be invaluable in the long-term in the smooth management of issues relating to your crane.

Customise Your Perfect Lifting Gantry System

Next document a list of features you require from the crane, this will include:

When purchasing a quality crane for your manufacturing facility or operation, it&#;s important to consider not just the price of the equipment but also its capabilities and capacities. There are plenty of overhead cranes available in a fair price range, but the cost alone cannot dictate your decision when choosing the right crane for your application. So, how do you ensure you&#;re buying the right machine for the right price? Our crane selection guide will walk you through the most critical considerations and provide some tips for ensuring you get the most from your investment.

1. Defining Your Expectations for Quality Cranes

To start, it&#;s always important to make your expectations clear from the beginning. Whether you are purchasing a crane from a dealer, vendor, or manufacturer, you must define and communicate your expectations to ensure you end up with the best product for your needs. Opting for a crane simply because of price can lead to many adverse outcomes, such as project inefficiencies, hefty upgrade or repair costs, and reduced life spans. 

Whether the crane can&#;t handle its workload or you&#;ve received an improper allocation, there are several concerns that can cost you time and money &#; and a lot of it. 

You can ensure that your crane is running when you need it by doing the following:

Contact us to discuss your requirements of Bespoke Cranes. Our experienced sales team can help you identify the options that best suit your needs.

1. Outline your application, operation, and facility requirements from the beginning, and be clear about what type of work your crane will have to endure.
2. Communicate the dimensional specifications needed and any other features that will ensure the efficiency of your new overhead crane.
3. Ask about warranties and what activities will maintain or void them.
4. Consider aspects to negotiate, such as transportation expenses, installation services, or delivery times, to make your purchase more cost-effective.
5. Plan a budget ahead of time, including maintenance and operating costs, to avoid monetary shortfalls.

2. Choosing Crane Size and Specifications

Crane size, capacity, and specifications will drive your purchase. Some dimensional specifications and features to consider are as follows:

• Crane capacity
• Span of the bridge or beam
• Overall height &#; dependent on your facility and any overhead obstructions &#; and lift height
• Runway lengths and number of bridges
• Steel or aluminum systems &#; including track and beams
• Any dimensional limitations that might impact the crane&#;s ability to function properly for your specific operation
• Motorization or manual system
• Festooning, rotation stops, taglines, casters, and any other additional features that will enhance your application &#; depending on which type of overhead crane you are buying
• Motion speeds, voltage, controls, and other various electronic features 

How to Select Crane Capacity

Your crane&#;s lifting capacity must match your project needs. A load chart is valuable for evaluating capacities and capabilities. These charts detail how much a crane can lift at various configurations to avoid overextending the machine&#;s limits. Using this tool requires you to understand several elements, including load weight, boom length, and radius. These measurements will depict how much weight a crane can carry at various distances from its center under perfect conditions.

Factors that impact overall crane lifting capacity include:

• Lifting range: The distance from the load center to the crane&#;s rotation center impacts capacity.
• Configuration: You can manipulate the lift capacity, depending on how you arrange counterweights and moveable parts.
• Boom angle and length: Longer booms have lower lift capacities, and the horizontal plane&#;s angle is also an important consideration.
• Operational conditions: Your operational environment, including weather elements like temperature and wind, and ground stability impacts capacities.
• Motion: A crane will have a higher capacity when it&#;s stationary compared to when it&#;s in motion because dynamic forces increase when a crane is moving.
• Dimensions and weight: Handling large and heavy materials can result in damage or injuries if the crane cannot safely manage them.

3. Evaluating the CMAA Service Class

A very important part of choosing the right crane for your total operation &#; and one that buyers often overlook &#; is the Crane Manufacturers Association of America (CMAA) Service Class that best fits your application. Operating your overhead crane outside its recommended service class is not only dangerous but very destructive to the crane itself. According to the CMAA, there are six service classes to consider:

• Class A &#; Standby or Infrequent Service: These cranes provide precise handling at slow speeds during installation and maintenance and offer long idle periods between lifts.
• Class B &#; Light Service: Light assembly operations and repair shops often use this class with light requirements and low speeds with varying load capacities. These cranes offer an average of 10 feet per lift, but you can find a range between two and five hours. 
• Class C: &#; Moderate Service: Most cranes satisfy Class C service requirements. Moderate service cranes can tackle loads averaging 50% of rated capacities with an average of 15 feet per lift and five to 10 lifts per hour. 
• Class D &#; Heavy Service: Operations requiring heavy-duty production, such as steel warehouses, foundries, machine shops, and lumber mills, utilize this service class to handle loads near 50% of rated capacities during work periods. You can operate these cranes at high speeds and expect 10 to 20 lifts per hour at around 15 feet per lift.
• Class E &#; Severe Service: Scrap yards, container handling, fertilizer plants, and cement mills often rely on Class E equipment. These cranes are capable of delivering 20 or more lifts per hour near or at rated capacities.
• Class F &#; Continuous Severe Service: Electric overhead traveling cranes and top-running bridge cranes are within this class, and they must deliver the highest level of reliability. This class can tackle loads approaching rated capacity throughout its lifetime. 

4. Finding the Right Manufacturer

Although your dealer will help you choose the right manufacturer for your new overhead crane, it doesn&#;t hurt to check out manufacturers and gauge their reliability and manufacturing standards. Here are some things to look for:

• Is the manufacturer ISO certified?
• Are all systems designed and stamped by a licensed engineer?
• Does the company offer on-site evaluation of material handling needs, and are they willing to make expert recommendations when needed?
• Do they manufacture pre-engineered and custom-engineered cranes?
• Are they eager to custom engineer systems to fit your specific application demands?
• Do they meet all applicable industry standards?
• Do they conduct finite element analysis and destructive testing on custom-designed systems?
• Do they utilize laser precision manufacturing and AWS-certified welding fabrication?
• Do they provide exceptional packaging and on-time delivery?
• Do they provide ongoing, on-site customer technical support?
• Do they offer a great warranty?

Importance of Preventive Care for Your Crane

Once you purchase and install the right crane for your total operation, it&#;s also important to implement a periodic inspection and preventive maintenance plan, which a qualified person from a crane service company should perform. It&#;s smart to plan the work around your production schedule to avoid as much downtime as possible.

If your overhead crane is down for unexpected repair or maintenance or you experience crane deflection, you are indefinitely losing money &#; the longer you have to wait to get it up and moving, the worse the situation. Consider these possible outcomes:

• Production losses: Production suffers greatly when an overhead crane is out of use due to necessary repairs and maintenance issues.
• Project downtime: Your application can come to a standstill if your crane is out of operation and you don&#;t have another machine to continue the project. Additionally, other jobs can suffer if workers are waiting to use the space under the non-working crane.
• Increased costs: Repairs can be very costly if you don&#;t carry a warranty. Check with your dealer or manufacturer to learn more about your warranty, including what it includes, how long it lasts, and what actions can void it.
• Inefficient shipping times: Cranes that are down can impact shipping. Inefficient shipping can hold up truck drivers waiting to load or unload products and cause your customers to wait longer for their products or materials. Longer wait times can lower satisfaction, which can greatly hurt your business and diminish customer loyalty.

In the end, you cannot eliminate downtime occurrences completely, but you can keep them at a manageable level when you buy the right equipment for the job and properly maintain it.
