On December 5, 2018, AXIS was invited to present on Lifting Equipment inspection Requirements. The is a general over view of the presentation.
Does everyone have a copy of the Act and Regulation on your desk? Is it current?? If you do that is great! When was the last time you looked at Part 23 and Part 28?
The sections of Part 23 that we are going to discuss are Overhead Cranes (CSA Code B167)
And Part 28 includes self-elevating work platforms, aerial devices and forklift mounted work platforms. (Vehicle mounted Aerial devices: CSA C225, Self Propelled Boom Supported Elevating work platforms: B354.4, Self Propelled Elevating work platforms: CSA B354.2, Portable Elevating work Platforms B354.1)
In the Act and Regulations, the sections reference the codes to which things shall be done. So, I wanted a photo of our code library. But I realized we no longer keep them all in hard copies, but on line, so they are available to our inspectors, when they need them, where ever they are.
When we look at the sections in the workplace safety and health regulations, we see all the words, and there are even code references. Do you have these codes? They can be purchased here:
We do. But many companies don’t have them. They are copywritten and we are unable to make copies and share them. But, our reports follow each one.
How are you supposed to know what to do, when you don’t have the guide book which gives the instructions? I am here to give you a brief guide.
Types of Lifting Equipment
An Overhead Crane (CSA B167) is made up of a Hoist, The Bridge, and a Hook. But did you know that your Overhead Crane, is actually held up by the Rails that it moves along? All the weight is resting on the “runway”, which is a structure either attached to the building, or has independent columns holding it up.
If you aren’t inspecting your runway and columns, then what is holding up the load? This is the structural component of the Structural Inspection.
Connections are the part of your crane that is attached to the columns. Connections can be
bolted or welded. These bolts become loose, and come off, where there are welds, the welds crack. When we inspect the Runways, this is one of the areas that we are most concerned with.
There are a number of structural components to Overhead cranes that aren’t always considered. There are catwalks. This is the platform that is used when accessing the overhead crane. This one had cracked all the way thru.
End Stops are the part of your crane that is stopping it from going off the end of the track. In this photo the End stop had been significantly damaged.
The fall arrest life line is the device that is installed when it isn’t possible to put in a catwalk. We started inspecting these when we first began doing overhead cranes, after the inspector working, got to the end of the runway to find the life line had been installed in correctly. The engineer had signed off on the installation without verifying the correct installation. Had our inspector fallen, the life line would not have held him.
Jibs, monorails and gantry cranes fall under the same code as overhead cranes, the primary difference is that these are not considered permanent fixtures and can be moved.
Mobile Cranes, come in all shapes and sizes, but are pretty well understood in Manitoba for the need of an Annual Inspection and Engineer Certification.
Mobile Cranes have 3 Codes that govern their requirements, Mobile Cranes, Articulating Cranes and Locomotive Cranes. (CSA Z150, CSA Z150.3)
Below the hook Lift Devices
Below the hook lift devices (ASME B30.20) come in all sorts of shapes and sizes. They are designed for specific purposes often.
This Gravel Bucket is a below the hook Lift Device. It is filled with Gravel and lifted by the crane and is suspended.
The areas that are circled are the key inspection areas for this lift device. These are the areas that are the most likely to fail.
This is a standard spreader beam. Any piece of equipment that is used to lift something else, would be considered a below the hook lift device.
There are areas that will be taking significant load. These areas get over loaded, they wear and they get damaged.
Elevated Work Platforms – Man-Lifts
Elevated work platforms are Equipment that lifts people. Did you know that a mobile crane requires inspection and engineer certification annually, but the equipment that is used to lift your people is only required to have a structural inspection after 10 years, then every 5 years after that?
Most companies have a daily or per use inspection form for personnel lifts. Did you know that each type of elevated work platform has a different code requirement and different components to be inspected? We work with 5 different codes for various types of personnel lifting equipment. (Vehicle mounted Aerial devices: CSA C225, Self Propelled Boom Supported Elevating work platforms: B354.4, Self Propelled Elevating work platforms: CSA B354.2, Portable Elevating work Platforms B354.1)
I am not saying that the daily inspection isn’t good. It is – It is GREAT, but, we need to consider how regular inspections are done.
Fork Lifts & Telehandlers (Material Handlers)
Fork Lifts and Telehandlers are the most common types of material handlers. These have their own code requirements when it comes to regular inspections. Including inspection of surface cracks, straightness of blade and shank, Fork Angle and other requirements. (CSA B335)
The area that we focus on for a structural inspection is the forks and the mast.
This is a photo of a set of Forks that the mechanic found a small crack in, Once we did NDT testing, a number of cracks became present. Once you can see a crack visually, It is often a sign of significant defects.
Examples of Equipment Failure
I often tell people that I am the product of an Artist and an Engineer having a baby, and I love using completely unrelated examples to explain technical problems. I have 2 for you today.
Have you ever had a favorite pair of pants, maybe a pair of Jeans, that you love, and you were them a lot, doing all your regular life stuff in them, and some not so regular life stuff? Then one day, you do something that you have done 100 times before, like pick up a pen, and you hear this horrific RIIIIIIIIP.
What happened, you did not gain weight, these pants were perfect, but that same movement, you have done 100 times before, and your pants failed you. There was a wear in them that you hadn’t noticed.
You now, are in a really tough position, because this never happens when it is convenient, and you were on your way at that moment to buy new pants. It happens at work, or on the way to a first date, or your child’s school play. It is a huge inconvenience.
Now, does anyone remember darning socks? Or watched the movie where they darned socks? might be dating myself, with this example. Your grandma or your mom would notice your socks were getting worn, and they would darn them up and they would last a few more months? They were cozy, and padded a little extra in that spot that was getting worn? Then on Christmas morning, you knew you were going to have a new pair of fuzzy warm socks?
Your socks were checked when they came out of the wash to see how worn they were.
Now, let’s translate this into equipment inspections.
If we don’t do regular structural inspections, we are risking a failure, the pants ripping, as the example gave. Best case scenario, no one is hurt, no other equipment is damaged or product is compromised. But there is still a piece of equipment that is down. Will this cause unplanned down time in production? Will your budget be stretched because you now have to urgently replace that piece of equipment that wasn’t planned?
But if instead, like darning the socks, we check our equipment regularly, and watch for wear, we do repairs as we need, begin to plan the replacement, and budget for the inspections to be completed during scheduled down time. Then replace when the budget was set, we have first and foremost, ensured the safety of our people. We have also, ensured that production is maximized and our budget is utilized efficiently.
AXIS wants to help you, to be your solutions provider. We want to give you the tools and resources to efficiently manage your safety inspections of lifting equipment.
You may have all this equipment at your site or facility and be thinking, how in the world can I do this all. It is like the saying, how do you eat an elephant…. One bite at a time.
I know for me in our own organization, Safety is a huge elephant. Let’s prioritize
1. High Hazards and Obvious Requirements
2. Mobile Cranes
3. Equipment manufactured before 2009
4. “Home made equipment”
Do you have any equipment that “Joe” the really good welder made, cause you needed something, and Joe, whipped it up? Go…… These pieces of equipment scare me the most. Because I bet Joe is a great welder, and knew exactly what was needed. But what about Edith, who is now using it for something totally different? Does she know what the capacity is? Is it being over loaded. PLEASE, if you have any “made in shop” lifting equipment. Please call the made safe team, or AXIS, we are both happy to help you.
5. Critical Equipment
6. Equipment manufactured before 2014
7. Overhead cranes, monorails, jibs, or gantry cranes? What is the inspection requirements based on CSA B167? Have they had a structural inspection? Have the connections and the parts that hold it up been inspected?
Safety is about everyone going home the same way they came in to work in the morning. As a business owner, I also realize the balance of keeping a company running.
I believe that scheduling your structural inspections of your lifting devices, will reduce your down time, from unplanned failures, reduce the cost of inspections due to urgency, and allow you to manage your equipment life and replacement by knowing its integrity on a regular basis.
Business is about your people and cashflow. Keeping people safe, managing your cash, by scheduled preventive maintenance will go a long way to your continued success.
If you take away one thing from this presentation today. Remember the story of the sock.
To close, we want o help you, we want to be your solutions provider, so if you would like a copy of our workbook that helps you list all your equipment, please send me an email and I will be happy to send it to you.
Until Next Week.
