In 1927, some of the country’s top crane manufacturers established guidelines for standardization in the quality and performance of cranes. They created the Electric Overhead Crane Institute (EOCI) to advocate for the safe operation of crane equipment and other products. Over the years, that organization evolved into the Crane Manufacturing Association of America, Inc. (CMAA).
As an independent trade association, CMAA is affiliated with the Material Handling Industry (MHI). It works to develop crane classifications, engineering specifications, inspection requirements, and maintenance factors while promoting education and professional development for members and advocating for safety within the industry.
CMAA Ensures Safety
Workplace accidents and injuries will always be a concern when working with cranes and other heavy equipment, but together we can all do more to prevent them. OSHA, via the CHM Alliance, works with a variety of organizations, including unions, trade organizations, businesses, faith- and community-based groups, and more, to create a culture of safety where employers take all necessary precautions and employees feel empowered to speak up about safety concerns.
The goal of these partnerships is to educate people about their rights and responsibilities regarding safety. They develop and provide compliance tools and educational resources.
CMAA Determines Inspection Requirements
Safety starts with equipment that works properly. The CMAA crane classifications help people choose the overhead hoist that is right for the job. This ensures the proper fit and speed related to what you’re lifting.
After you have the right hoist, you need to make sure it’s in working order every day. The Occupational Safety and Health Administration (OSHA), the American Society of Mechanical Engineers (ASME), and the Hoist Manufacturers Institute (HMI) all dictate regular overhead hoist inspections, which allow you to identify any problems with the equipment before you use it.
Hoist inspections are not to be performed by anyone without the proper training. That formal education should include training in operations, crane safety codes along with federal, state, and local regulations, crane and overhead hoist terminology, and how to document findings. The CMAA specifies that crane inspectors need a minimum of 2,000 field experience hours in maintenance, servicing and repairing, and testing and modifying cranes and hoists.
Maintenance Factors Are Established by CMAA
Each type of hoist has its own set of guidelines for maintenance as set by the CMAA, and OSHA and ANSI outline when cranes should be inspected:
- Initial:New and altered cranes must be inspected to ensure compliance with regulations.
- Functional:Cranes should be inspected before every shift. Following a daily hoist inspection checklist ensures you don’t forget anything or grow complacent with the inspection.
- Frequent:These inspections include everything in the functional inspection as well as operating mechanisms. These are performed more often if the crane is in heavy use.
- Periodic:The frequency of these in-depth inspections also depends upon how heavily the crane is used, which may be annually or quarterly. Some states require more frequent periodic inspections, no matter how often the crane is used. California, for example, requires quarterly inspections.
Your daily hoist inspection checklist will help you discover any damages and concerns like excessive wear, shiny surfaces, corrosion, leaking engines or cylinders, or blistering hoses. These may indicate you need maintenance or repair, which is essential to keep your crane running safely.
CMAA Members Respond in Crisis Situations
Now more than ever, the companies of the MHI Overhead Alliance are committed to their employees and communities. These uncertain times have called for continual evaluation and consideration to make sure everyone is doing everything they can to help.
CMAA has been supporting those customers serving at the front lines of the pandemic. Communication efforts have increased, particularly email from key leaders, project managers, and account managers, to keep people posted about projects and operations, all of which are moving forward. Members have stepped up to fulfill vital needs, including the design and customization of overhead handling equipment to be used for producing life-saving medical equipment. Various suppliers have fulfilled emergency deliveries of parts for crane maintenance and repair. Others have focused on charitable outreach by donating PPE to local hospitals and sending funds to non-profit organizations.
CMAA recognizes the vulnerability of the community at this strange and sensitive time. They want to help, and they will continue to identify ways to do so. Moving through the crisis means moving through it together.

In the manufacturing and construction industries, overhead cranes lift and transport necessary materials for a wide range of applications. When installed and used properly, these systems facilitate safer, more efficient operations. However, improper installation and usage can cause accidents that result in severe injury to life and limb. The key to preventing these incidents is recognizing their sources so industry professionals can better understand how to avoid them.
The following blog post outlines the four major hazards related to crane installation and usage and the recommended safety procedures to circumvent them.
Common Crane Hazards
Most overhead crane accidents stem from one of four major causes:
1. Excessive Load
OSHA estimates that 80% of all crane accidents and failures result from exceeding the rated capacity of the crane. Overloading can cause significant damage to the crane, decreasing its structural integrity and often leading to complete failure. Once these occur, crane operators and nearby personnel can be injured by falling or failing parts.
Overloading may occur in several different ways:
- Handling a load heavier than the crane’s capacity
- Swinging, dragging, or suddenly dropping a load
- Side-loading a boom (Any time the load’s center of gravity is not directly under the crane.)
For crane operators, understanding these leading causes of overloading and how to avoid them necessitates comprehensive training. A typical training regimen may include imparting knowledge about the principles of load handling and hoisting capacities for various conditions and operating conditions.
2. Falling Materials
In the workplace or at a jobsite, falling materials can cause significant injuries or fatalities. These incidents can occur due to many reasons, such as:
- Visual impairment
- Improper or inadequate rigging of materials
- Mechanical failure
- Ill-timed movement of materials
- Operator incompetence
Most, if not all, causes of falling materials can be avoided through the careful operation of the crane, which is facilitated by employing well-trained and qualified crane operators.
3. Insufficient Inspection and Maintenance
Through use in operations, loading bearing equipment experiences damage that can affect performance. This damage can take the form of worn-out ropes, electrical wires, and structural components. As these systems play a critical role in lifting and transporting heavy materials, ensuring they are in proper working order through regular inspection is essential to preventing employee injuries and fatalities.
As outlined by the Crane Manufacturer’s Association of America (CMAA), crane inspectors should have the following:
- At least 2,000 hours of experience inspecting, maintain, repairing, and testing cranes and hoist equipment
- Knowledge of safety and design standards; federal, state, and local codes; and safe operating practices
- Understanding of proper reporting and documentation protocols
There are four types of inspections, some performed by a crane inspector and some by the operating personnel:
- Initial Inspection: OSHA 1910.179requires an initial inspection for all new and altered cranes.
- Pre-shift Inspection: It is advisable to do an inspection every time there is a change in the crane operating crew, such as when a new shift starts.
- Frequent Inspection: These are done by certified inspectors. The frequency of these inspections varies with the type, size, and capacity of the crane.
- Periodic Inspection: These are detailed visual inspections and operational checks that cover every part of the crane.

Dependable equipment is critical to your business. It keeps processes running, protects materials, and increases employee safety. Forklifts must be well-balanced and overhead cranes must be sturdy and steady enough to lift heavy loads. Unfortunately, in spite of safety standards, cranes are often pushed beyond their limits. Like all equipment, cranes wear down over time, and as they do, their capacity decreases.
What can you do when your overhead crane is no longer up for the work you need it to do? You can replace your crane or you can rebuild it. In this blog post, we’ll look of the benefits and drawbacks of each solution to help you make the best decision for your company.
In the short run, it’s tempting to opt for the quicker, less expensive option of repairing equipment as issues arise. Depending on the cause of the problem, however, however, these up-front savings could impact your crane’s long-term performance and reduce employee safety over the long haul.
Here are some signs it’s time to allocate funds for a new crane:
- Safety issues. Don’t compromise on employee safety. Track the frequency of injuries and breakdowns, especially if you can’t pinpoint the cause of these problems. If you’re not sure whether these issues are substantial enough to require a replacement, contact a professional to inspect your crane and make a recommendation.
- Repeated repairs.An occasional repair doesn’t mean it’s time to scrap your crane. However, if repairs are becoming a regular ritual or each fix just seems to lead to more problems, it’s probably time to either replace your crane or replace key parts.
- Decreasing efficiency.Take a look at your crane’s performance data. Has its speed or weight-bearing ability dropped over time? Has operating the crane become more difficult for your workers? While these changes might seem minor at first, they can ultimately affect the effectiveness and profitability of your operation.
- Expired warranties.If the warranty on a part or system has expired, its best days are probably behind it. Many parts also have manufacturer-recommended replacement timelines. It’s best to replace expired components as soon as possible.
If your crane is structurally strong and free of deterioration or damage, rebuilding could extend its life without sacrificing safety or effectiveness. An overhaul or upgrade might be all you need to minimize malfunctions, increase dependability, comply with safety standards, and protect your operators.
Here are some situations where an otherwise sound crane might be a good candidate for repair/rebuild.
- Insufficient capacity. Older cranes had limited weight capacities, but technology improvements
over the past couple of decades mean that many older cranes can be retrofitted to handle heavier loads.
- A specific system has broken down.Individual crane systems deteriorate over time. Once-adequate systems might also no longer be up to the demands of modern manufacturing. By updating lift, drive control, hydraulic, computer, or other systems, you could give an otherwise sound crane many more good years.
- Safety features have worn down. Railings, walkways, steps, ladders, and other safety features may wear out long before your crane does. Upgrading these features allows you to continue using your crane while still complying with relevant safety standards.

Below-the-hook lifts are crucial for the safe transport and movement of loads when using cranes and hoists. The goal of a below-the-hook lift is to attach a load to the crane or hoist and secure that load until it reaches its final destination. The lift serves as the connection between a hoist and its load, and must therefore be able to sustain heavy loads while maintaining a high level of stability.
A below-the-hook lift may consist of magnets, lifting beams, grapples, or vacuum lifters, and often includes secondary components such as slings, hooks, and rigging hardware. The materials and equipment used in below-the-hook lifts vary widely depending on the application. Due to their critical nature, below-the-hook lifts are highly regulated by the American Society of Mechanical Engineers (ASME), which provides guidelines for designs, inspections, and testing to ensure a standard level of quality.
An Overview of Below-the Hook-Lifting
Cranes and hoists are necessary for a wide variety of circumstances, which often requires engineers to customize the design of below-the-hook lifts to meet the needs of a given project or application. Below-the-hook lift designs are frequently adapted to account for a load’s center of gravity, shape, and size, and customization of these designs helps to guarantee safe operation of crane equipment and efficient transport of the load or loads.
In order to ensure that the below-the-hook lift is designed for optimal use, both the manufacturer and the customer participate in the engineering process for each application. This ensures design engineers and project managers consider the precise needs for the project so that they can produce a lifting solution that meets every need.
There are a wide variety of mechanical below-the-hook devices for use with cranes and hoists, including:
- Lifting magnets
- Spreader and lifting beams
- Crane grapples
- Custom Devices
Each design can be specifically modified with custom designed claws, hooks, tongs, and latches to ensure the most secure fit. Depending on the needs of the application, mechanical below-the-hook devices can be operated using electronic or hydraulic means.
Advantages of Below-the-Hook Lifting Devices
Below-the-hook lifting devices are the ideal option to provide the safest and most reliable load transport. Although traditional slings of wire rope, alloyed metal chains, or durable synthetic materials are easier to construct, they are not the safest way to move loads and often move or shift unexpectedly. Unpredictable load bearing puts both equipment and workers at risk, especially when transporting loads with an unusual shape, size, or weight.
Below-the-hook lifts are specifically designed to ensure optimal control of the load. Not only do they enhance the safety of the worksite, they save you time and money that would otherwise be spent finding a creative workaround with a sling or other existing equipment.
Since they are highly customizable, below-the-hook lifts are useful for even the most difficult loads. For example, if your project requires the ability to lift loads with varying centers of gravity, they can easily be managed with a custom designed below-the-hook lift with an adjustable bail. Whatever your project needs, a lifting device can be designed to move your loads more efficiently and safely.
Below-the-Hook Lifting Devices from American Crane
Below-the-hook lifting devices must be carefully designed in collaboration with experienced engineers and customers in order to ensure the safety and security of load transport in any project or application. At American Crane, we pride ourselves on providing the highest-quality custom cranes and hoist equipment in the industry. Our knowledgeable and experienced engineers are capable of designing systems to secure and move loads for a wide range of projects and applications.

Employees move in and out of manufacturing facilities and shipping/receiving areas many times during a normal work day. When doing so, they must coexist with a wide variety of large and dangerous equipment.
Overhead lifting systems work within a specific area to limit potential risks posed to employees and bystanders. Doing so allows lifting equipment to operate as efficiently as possible without affecting your facility’s safety levels.
Properly implemented overhead lifting systems allow product to be transported safely. Have you considered the costs related to OSHA citations, increased workers’ comp rates, potential lawsuits, medical expenses, and the temporary or permanent replacement of an injured employee? These issues cost employers billions of dollars annually. This makes investing in the safest lifting and moving systems more than just ideal—doing so is a practical, cost-saving proposition.
Inspection Requirements for Overhead Cranes and Parts
Overhead Crane Requirements
Routine inspections are required to guarantee continued safe operation of overhead cranes because of the size and weight of the objects they regularly lift and transport overhead. Whether a crane is new or altered, an initial inspection is necessary before it can be used.
Once overhead cranes are placed into service, they require two unique types of inspections:
- Frequent inspections, which occur daily to monthly
- Periodic inspections, which are completed 1–12 times per year
These types of inspection are intended to examine key components of the crane. This helps to determine the extent of malfunction, deterioration, or wear and tear on the crane’s components.
Items that Need Inspection and Their Frequency
The following items require daily inspection:
- Functional operating mechanisms: These systems must be checked for maladjustment
- Hydraulic and air system components: Valves, lines, tanks, drain pumps, and other components must be checked for deterioration or deficiency
- Crane hooks: These must be checked for cracks or deformation
There are also several features that require monthly inspections or other actions:
- Rope and end connections: These must be run to check for broken strands or wear every month
- Hoist chains and end connections: These must be checked for distortion, twit, excessive wear, or anything else that may interfere with their proper function or cause them to stretch beyond their manufacturer’s recommendations
- Written records: All records must be carefully updated with each inspection that is performed
Other inspections are performed on an as needed basis. Test functional operating mechanisms for excessive wear regularly. This may be daily or monthly depending on the amount of use your crane system gets. Rope reeving inspections should be completed as needed or recommended per the manufacturer’s instructions.
Maintenance and Design Requirements
OSHA specifies a number of design requirements pertaining to the construction of the crane’s cab and its controls. OSHA also outlines many regulations that govern the cab’s lighting, footwalks, ladders, and stairways. OSHA recommendations additionally cover the following components:
- Bridge and trolley bumpers
- Hoist, holding, trolley, and bridge brakes
- Electrical components
- Hoisting equipment
- Warning devices
You must implement a preventative maintenance program according to the recommendations of the crane manufacturer. If you detect any unsafe conditions or deteriorated components during your required inspections, you must complete maintenance before you can use the crane again.
Only designated personnel are allowed to perform the necessary repairs and maintenance. The requirements of 29 CFR 1910.147, the control of hazardous energy or tagout/lockout, should be used to de-energize the crane.
