Mastering Overhead Crane Maintenance: Top 3 Issues and How to Prevent Them

1.Why Regular Maintenance is Non-Negotiable for Overhead Cranes

Any seasoned business owner understands that machinery requires consistent upkeep. The overhead crane is no exception. Designed to streamline workflow and boost efficiency, these cranes are a substantial investment for any enterprise. Yet, like any piece of machinery, they are subject to wear and tear. And a poorly maintained overhead crane can quickly become a safety hazard and a financial drain.

2.Top 5 Common Issues with Overhead Cranes

Recognizing the problems before they escalate can save you both time and money. Below are the top 5 challenges you're likely to encounter with your overhead crane system and how you can prevent them:

1. Wire Rope Degradation

Arguably the most critical component of an overhead crane is its wire rope. Various problems can plague the wire rope:

• Jumping off from the reeving system
• Rope diameter reduction
• Worn-out external wires
• Broken or corroded cables

Prevention: Conduct an inspection before each shift. Also, lubricate the wire rope. Proper lubrication not only reduces friction between the wires but also protects them from corrosion.

2. Alignment and Crane Skew

When your crane is out of alignment, the results can be disastrous. From stressing your building’s structural integrity to causing dangerous accidents, the risks are many.

Prevention: Keep an eye out for signs like cracked wheel flanges or loud scraping noises. A regular inspection by a reputable service provider can ensure your crane operates according to the guidelines set by the Crane Manufacturers Association of America.

3. Excessive Wear on End Truck Wheels

End truck wheels naturally wear down due to regular use. These wheels are made of materials that vary in durability, from carbon steel to polyurethane.

Prevention: Choose a crane manufacturer who understands wheel-rail hardness compatibility. This will reduce premature wear and extend the crane's life.

3.Maximizing the Lifespan of Your Overhead Crane

Tailor Your Crane to Your Needs

Never opt for a crane that doesn't meet your operational requirements. The right crane can handle your business's specific load capacities and duty cycles, ultimately saving you money on repairs.

Consistent Inspections are Key

Regularly inspect your crane to catch issues early. Following manufacturer guidelines is essential, but so is hiring a third-party service provider to double-check everything for you. Their expertise can be invaluable.

4.Tips for periodic maintenance of your equipment

• First, create a list of physical assets and equipment that you have in your inventory. While preparing this list, you must focus on different factors, including hours of operation, working conditions, and the size of equipment.
• Engage professionals and consult with them about the standard working conditions of your devices. This step is important for better maintenance of your equipment.
• You need to analyze your past maintenance programs and then create a schedule for periodic monitoring of the systems. To take preventive measures, it is better to make a monthly or weekly schedule. You can hire a trained and certified technician to deal with your material handling equipment.
• You may invest in some spare parts of the equipment. Sudden failure to mechanical components may affect your business operations. Thus, you can buy these spare parts and follow manufacturers' instructions to use them.

5.Preventive maintenance program for your equipment

A comprehensive program for preventive maintenance is essential to downtime and equipment failures. Timely replacement of wearing part will benefit you in the future. To prevent the disruption of your business activities, you have to maintain your equipment. Moreover,

Preventive maintenance enables you to

• Keep away from high emergency repair costs
• Sustain the optimal efficiency level of your material handling equipment
• Have long-lasting serviceable life

There is another reason for investing in regular equipment maintenance services. As these systems work properly, you can keep up the production level in your business. Thus, you can serve your customers in a better way.

Although you need to incur an upfront cost, preventive maintenance will cost you less in the long run. Well-maintained devices ensure higher efficiency of managing materials and heavy loads.

6.Schedule a predictive maintenance program

Although you have paid attention to preventive maintenance, predictive maintenance is another important option. You need to have a track of regular servicing of your equipment.

When you have old material handling devices, you may replace them. You can implement some automated systems for monitoring purposes, or rely on only the manual process to accomplish it. Some automated systems present you with real-time updates about the condition and performance of your industrial equipment.

7.Best Practices for Preventive Care

Preventive measures are less costly in the long run and can address up to 90% of common servicing issues. Consistent overhauling and maintenance reduce build-up of elements like dirt and rust, preventing further damage. Always remember, the hardness of the new set of wheels should match the old set to ensure compatibility.

8.Develop a regular and in-depth inspection schedule

Prevention is always a better approach than cure. With that said, you should focus on reducing the overhead crane downtime than spending resources and time on repairing and replacing the damaged units. As per our technical team's guidelines, you should develop a regular and in-depth crane inspection schedule. The objective of the inspection should be to identify the probable troubles that are likely to come up. Consequently, those units should get appropriate preventive measures, including repair and replacement, as and when needed. Regular inspection will help you spot the forthcoming challenge early before it takes some devastating toll on the overhead crane. It is the only effective way to keep the crane in perfect working condition. Small repairs and replacements will help you to escape the threats of incurring major troubleshooting activities at a later cost that inevitably results in massive expenses. On the other hand, time repair and replacement help you minimize workplace injuries, thus securing your workforce. You must comply with the international guidelines for crane inspection. You can even think about engaging professional inspection agencies who are specialized in handling similar assignments. Their engagement brings more expertise and skill to produce the most delightful outcome.

9.Ensure that the crane operators are trained and certified

Mishandling is one of the most potent factors to trigger downtime. It implies, that if the crane operators are not operating the crane in compliance with the standard operating policies, the crane will catch downtime more frequently. Such unsolicited activities of the operator result in some major damages to the cranes that are mostly impossible to repair. Consequently, the company gets compelled to absorb the blow of longer downtime, ripping through the desired productivity and efficiency standards. Therefore, you don't have alternatives other than to recruit trained and certified operators to operate the overhead cranes. The training will enable the operator to operate in the most prudent manner, eventually downsizing the chances of downtime. It is equally important that you arrange for skill upgrade training for crane operators on an ongoing basis.

10.Adopt Remote monitoring technology

Remote monitoring technology will enable you to monitor the overhead cranes more closely and on an ongoing basis. It will support you in taking the appropriate steps to prevent the cranes from hitting the downtime phase. At the same time, it will help you to extend better safety and protection to your workforce.

11.Proper Safety And Maintenance

Proper crane maintenance must be given the highest priority. While in operation, a crane poses a lot of health hazards. The following preventive methods must be taken to ensure safety.

• For safety purposes, inspections of worn or cracks in the wielded area must be checked.
• The hook roller brackets, welds, locking devices, bearings, pins, shafts, gears, and removable outrigger attachment must be checked before using.
• Check all brakes, including both the bridge and trolley motor brakes, before the start.
• The main chords and lacings must be checked for signs of paint cracking or flaking.
• You are likely to ensure that the bridge and trolley motor brakes function properly and also check if all the below-the-hook devices are in good condition.
• Test proper calibration on all indicators, including load and boom angle indicators of the crane.
• Correct response of brakes, motion lever, and locking devices must be checked. Apart from that, the accuracy of the rated capacity indicator (RCI) or load moment indicator (LMI) must be checked.
• The crane must be inspected periodically. This includes loose, missing bolts, pins or nuts, cracked, worn or distorted parts.
• You need to give additional attention to the hook block. It would help if you inspected whether the wire rope and load chain are in the right positions or not. If those are not in the right positions, fix their positions.
• The operator should be very attentive while the crane is in motion.
• Make sure there’s no kinking, cutting, crushing, un-stranding or thermal damage to the wire rope and the chain sprockets are operating smoothly.
• The safety must be checked or inspected by professionals, and recommendation should be given for better safety of the crane’s health

Every crane should have a proper inspection and maintenance plan, based on the use of the machine and the manufacturer’s recommendations. Serious damages can take place if the maintenance is not done properly. The crane must be stopped from using if any malfunction or unusual noise is detected. Not only to operate the crane, safety and inspection must also be done by qualified and skilled operators. All the parts that were repaired creating safety hazards must be corrected. So, if you continue to operate your cranes with known safety hazards, then you are putting your worker’s safety in great danger.

12.Maintaining Cranes and Hoists in Cold Weather

The impacts of cold

Some of the standards reinforce that the standard lifting equipment for cranes may not suit cold weather use. The temperature limitations in some of this equipment may vary a little from the standard. But in any case, one can understand how temperature can harm the equipment you are working with.

The coldest temperature is known to affect the tensile toughness of most of the materials commonly used in any construction site. Tensile toughness is the material's ductility and brittleness. Some materials are known to absorb a large amount of impact energy before they undergo any fracture. It can result in bending or deformation. It, however, alerts the operator to look for any overload situation before failure takes place.

On the other hand, brittle materials can shatter while receiving any impact. Most of the materials experienced are shifted from flexibility to brittleness if the temperature suddenly drops below the limit. The temperature at which this shift takes place is known as the ductile to the brittle transition temperature. One should note that any brittle failure can be catastrophic and unpredictable. It can occur from any random impact or dynamic loading. In some cases, this impact propagates due to the stress riser like knick or cracks.

Weatherizing the crane with coatings

The best way of weatherizing steel components is by using special coatings. For instance, you may use galvanized and epoxy coating to ensure the ultimate protection of your steel components from the effect of lower temperatures. While epoxy coatings are friction resistant, they also protect the surface from heat and corrosive elements. Moreover, hot-dip galvanizing is another reliable choice used in cold and harsh environments found in warehouses and production facilities.

Two-part epoxy coatings are the right choice for steel used for industrial purposes. What is more, they can protect your steel system from turbulence, corrosive fluids, and impact forces.

On the contrary, hot-dip galvanizing is the right choice when you are using your material handling equipment in salty regions. To protect your crane components, like steel beams, you can rely on this weatherizing method. Furthermore, galvanized steel is highly effective and reliable as your steel gets zinc coatings during this process. The galvanizing technique also creates a thick and protective layer, and you can apply it rapidly.

13.Choosing a Crane Maintenance Company

Is it a reputable company?

The first and foremost rule of selecting a crane service company is to ensure whether or not it is reputable. Go through the reviews and feedback the company has received online. Make sure to see what everyone has to say about their services, experience in dealing with EOT crane maintenance, and other types of feedback. Are they reliable enough to offer the support you need when required?

Evaluating their availability

Your timeline will determine your need for crane maintenance services. This is another factor that will enable you to prioritize one over the other. Whether your project is in immediate need of service or you have a long-term project with a flexible time frame. You must consider the availability of crane maintenance services. Choose companies that will be able to accommodate your timeline. This will ensure your potential list is both relevant and short.

Have you seen their credentials?

Crane maintenance services vary from one another in the requirements they have. Not all crane operators have the same training. Ask for the credentials that service operators have. Once you get hold of their credentials, compare them with other crane maintenance service providers. This gives you the necessary information you need to choose the most suitable service providers.
