Hoist Pre-Operational Safety Inspection Part 5: ASME B30.10 Hook Inspection

Hoist Pre-Operational Safety Inspection Part 5: ASME B30.10 Hook Inspection

This article is Part 5 of a 7-part blog series that will cover what operators should consider when performing a pre-operational hoist safety inspection. Today, we’ll discuss ASME B30.10 hook inspection.

ASME B30.10 covers hook inspection for all hoists, cranes and rigging hooks. Before operating a hoist, it is important to inspect the hook to ensure it is safe and free from defects before lifting a load. When inspecting the hook, there are a few key things to look for:

1. Deformation

Deformation can be an indication of overload, side loading or utilizing improper rigging techniques. In some cases it may be apparent that the hook is deformed. Look for any bends, twists, cracks or sharp edges that could cut into your synthetic slings.
To check for less-apparent deformities, measure the hook’s throat opening. (Note: Typically this is not done during pre-operational inspections.) You should remove the hook from service if any distortion is noticeable. Check the throat opening.  It should not be more than 5% or 1/4″ from the manufacturer’s original dimension. Check your manufacturer’s recommendations.

Also, some hooks have manufactured marks or bumps between the throat opening and the saddle of the hook. These are reference points for measurement. These can be found on our Hurricane 360° hoist. Each hoist manufacturer’s manual will tell you how to measure the hook.

2. Wear Corrosion

Look for excessive wear or corrosion on the hook. Any wear exceeding 10% of the original section dimension of the hook or its load pin means the hook should be removed from service.

3. Nicks & Gouges

There is an easy rule of thumb you can follow when checking for nicks and gouges – any nick or gouge that you can fit your finger nail into is cause to remove the hook from service.
As you can see in Figure 1, these gouges were put here on purpose to serve as points to measure hook deformation, but, by making these marks, they have created stress areas that can cause the hook to easily fail.

4. Latches

ASME states that hooks shall be equipped with latches and they have to be operable. Latches hold the rigging in the hook when in slack position. They are not meant to be a load bearing piece, which can easily happen when using improper rigging techniques.

To check the latches, ensure that the latch  bridges the throat of the hook when in the closed position and that it operates properly.

Hook latches are required unless it can create a hazardous condition. For example, if you have to climb on a load to release latch (fall hazard) instead of using a push stick to back the hook out of the attachment point.

5. Bolts & Pins

Check to make sure that all bolts and pins in the hook are secure. You can see in Figure 2 that the pin is sticking out which is a cause for concern. Check the pin to make sure the chain is properly connected to the hook block. Also check to make sure that the hook swivels and rotates freely when not under load.

6. Markings

Look for proper hook markings, including the manufacturer’s logo.

7. Field modifications

Figure 3 is an example where someone welded on a sister hook. While this may be ideal for their application, these have heat damage and are ruined. If you need a unique hook, you should have an experienced manufacturer do this.

If any of these conditions are present or if you see anything on the hook that causes you concern, take the hook and/or hoist out of service until it can be replaced or repaired.

Hoist Pre-Operational Safety Inspection Part 3: Markings and Labels

Hoist Pre-Operational Safety Inspection Part 3: Markings and Labels

This article is Part 3 of a 7-part blog series that will cover what operators should consider when performing a pre-operational hoist safety inspection. Today, we’ll discuss markings and labels.

Markings and Labels
Lock-out tag or label

The first thing you want to check for during a Pre-Operational Inspection are markings. One type of marking to look for on the hoist is a lock-out tag or label. It is usually placed on a hoist during a repair or if the hoist has been taken out of service.

If you do find this type of marking on the hoist do not remove these tags or try to operate the hoist – there is a reason why the tag is there. It is also important to note that this tag must be removed by the person who put there.

Markings and Labels
Hoist identification

Next, look for a tag or plate with hoist identification and capacity information. It should be stamped on or affixed to the unit.

When you look at the CM Bandit nameplate, for example, the capacity should be clearly marked. The manufacturer, Columbus McKinnon, should also be identified and there should be a serial number. All hoists should have this information on them somewhere, whether it’s on a plate like you see on the Bandit or elsewhere.

Lastly, check the hoist for warning labels. Many hoists, like the Bandit, have this information on the same plate as the manufacturer and capacity. Some hand chain hoists have warning information on a plastic sleeve around the hand chain. Operators should not remove these. This warning information must be on the hoist somewhere for the hoist to be compliant with ASME  B30.21 and ASME B30.16.

All operators should take the time to read and re-familiarize themselves with the warning information on the hoists they use. This will help refresh their memory and ensure they are using the hoist properly.

If this information is missing, especially if you cannot determine the capacity, you should not operate the hoist until you check with someone to get that information. This will help ensure safe operation and prevent injuries. Any hoist without these markings and labels should be taken out of service.

Hoist Pre-Operational Safety Inspection Part 2: The Difference Between Frequent and Periodic Hoist Inspections

Hoist Pre-Operational Safety Inspection Part 2: The Difference Between Frequent and Periodic Hoist Inspections

This article is Part 2 of a 7-part blog series that will cover what operators should consider when performing a pre-operational hoist safety inspection. Today, we’ll discuss the difference between Frequent and Periodic hoist inspections.

There are two classes of hoist inspections: Frequent Inspections and Periodic Inspections.

Frequent Hoist Inspections

Frequent Hoist Inspections are what we refer to as Pre-Operational Inspections. These are the inspections we do between the Periodic Inspections. You do not need to maintain records of these inspections. We recommend that Frequent or Pre-Operational Inspections are conducted at the start of every shift to ensure the hoist is in safe working order. Frequent inspections allow you to determine if anything is wrong with the hoist before lifting a load.

Periodic Hoist Inspections

Periodic Inspections are thorough, detailed inspections that may require complete disassembly of the hoist. These inspections are conducted based on the hoist service (how often the hoist is used) as well as in which environment they are used. You must have a documented history of hoist inspection. Periodic inspections are required by OSHA, ASME and the manufacturers. Periodic inspections are written, documented inspections that you are required to keep on file to ensure your equipment is safe to use.

The type of service determines the inspection schedule.

Hoist Inspection Schedule
If you find a lot of issues with a hoist during a Periodic Inspection:

  • You may need to increase the number of inspections you conduct each year.
  • Your operators may need to be trained to ensure they are using the hoist correctly. Hoists should not be damaged if they are being used properly.

While inspection records don’t need to be maintained for Frequent (Pre-Operational) Inspections, a pre-operational checklist can serve as a quick reference when conducting these inspections. The checklist provides a step-by-step guideline of essential items that should be checked during a Pre-Operational Inspection.

Although everything on this checklist may not pertain to every hoist, it is a good reminder of what to look for. The checklist does not NEED to be filled out before every shift. Even so, many companies require it to ensure operators are doing these checks and doing them correctly. We suggest that you laminate and zip tie the checklist to the hoist pendant, or somewhere on the hoist, to remind the operator to do it. Download the checklist here.

Hoist Pre-Operational Safety Inspection Part 1: Safety Standards and Regulations

This article is Part 1 of a 7-part blog series that will cover what operators should consider when performing a pre-operational hoist safety inspection. Today, we’ll discuss Safety Standards and Regulations.

When using hoisting equipment, it is very important to know and understand all of the safety and inspection standards that apply to your lifting system. Depending on the type of equipment you are using, different standards may apply. This can often be confusing as different regulations apply to different parts of the lifting system.

To explain, let’s start with an overview of the most important safety standards and which part of the lifting system they apply to.

ASME is an organization that provides design and inspection standards for hoists and rigging products. ASME is a voluntary committee made up of industry experts. Their standards are voluntary standards updated every three years – not laws like OSHA regulations. Standards are used as guidance for safety because many of our products do not have applicable OSHA regulations.

The first ASME standard you need to be aware of is ASME B30.16. This standard applies to underhung powered hoists, including electric and air, as well as chainfalls. This standard covers construction, marking, inspection, use, and training.

In the entertainment industry, these hoists are covered by ANSI E1.6-2.  We recommend if you are in entertainment to obtain a copy of both standards.

The second standard to be aware of is ASME B30.21, which applies to lever hoists, including chain, wire rope and strap hoists.

Where it gets complicated is that, in many cases, there are multiple safety standards you need to understand to use or inspect a single hoist. Take the CM Bandit for example:

  • ASME B30.21 applies to the entire hoist
  • ASME B30.10 applies to hook inspection, how to use the hook properly, etc.

In this case, you have to understand two standards to ensure proper use and inspection of the Bandit hoist.

When using a full lifting system, the number of applicable safety standards can be even more overwhelming.

Below is a diagram of all the standards that can affect a single lifting system. Depending on whether you’re an operator or inspector, there are specific parts of these regulations you need to know detail. When in doubt, always check with the equipment manufacturer.
