Heavy lifting equipment is essential to every industry, whether it be aerospace, construction, automotive, or food & beverage.
By use of manual or electric operation, hoists can move heavy loads vertically using a drum or lift-wheel. Of these hoists, there are two main electric types that industry professionals rely on – chain or wire rope hoists. When analyzing a lifting task at hand, the most important factors to consider for each of these hoists is application type, environmental conditions, capacity and duty cycle.
Chain hoists lift by pulling the chain through sprockets and moving the chain into a chain holder. These sorts of hoists are more commonly used for applications with loads below 10 tons and require much less maintenance as opposed to wire rope hoists.
Chain hoists are also different in that they provide true vertical lift, meaning they rise straight up with absolutely no lateral movement.
True vertical lift is used for applications requiring extremely precise vertical placement. Chain hoists serve as an economical alternative for less demanding jobs in shops and rougher environments.
Chain hoists are suitable for such situations because they are usually enclosed and protected against chemicals or outdoor elements.
On the other hand, wire rope hoists lift loads by wrapping a cable around a grooved drum. For 10 tons and above, wire rope hoists are the optimal choice on the market. This category of hoists is generally known to offer a wider variety of options with very fast lifting speeds.
Wire ropes are the preferred choice for frequent use as chain hoists are more susceptible to wear and tear over time. Wire ropes, however, move loads very slightly laterally because the wire rope is wrapped around a grooved drum.
Although the lateral movement is negligible, true vertical lift is only achieved with chain hoists, and this is important to keep in mind for precise vertical placements for something like stripping molds.
Duty ratings are the final, and perhaps most significant piece in understanding which hoist type will provide the best durability for your application.
Defined by various institutions, hoist duty classifications are published standards for material handling and strength that can help identify which hoist is most suitable for a project. The three most commonly used classifications for electric hoists are FEM, HMI, and CMAA.
FEM refers to the European Federation of Materials Handling which uses two main factors to provide its classification: load spectrum and average daily operating time. This standard is uncommon in the United States, but may still appear in hoist specifications.
HMI is the Hoist Manufacturer’s Institute and reports its classification using factors like the number of lifts per hour, max number of stops and starts per hour, the average distance of vertical movement, and lifting frequency of the load.
CMAA is known as the Crane Manufacturer’s Association of America and bases its values on the crane’s number of lift cycles accompanied by its average load intensity. A huge difference to keep in mind when looking at HMI and CMAA numbers is that HMI only rates hoists and not the entire crane.
The most frequently used ratings are HMI and CMAA when comparing different hoists. For HMI, expect to see specifications ranging from H1 through H4, with H4 indicating high volume handling of heavy loads. When looking at CMAA ratings -which apply to cranes- they range from Class A through F, with F being the heaviest.
These specifications are just a brief guide to better understanding the difference between chain and wire rope hoists. Considering factors such as the purpose and load of the lift and also analyzing durability and duty ratings will prepare you for making the right decision about a suitable hoist for your next project.

American Crane’s Star-Powered Inventory
With decades of experience connecting business in a wide range of industries with cranes for almost any application, American Crane has seen it all. Contact us today to find out how we can provide you with the cranes you need…even one with a star-studded Hollywood pedigree!
American Crane and Equipment Corporation was recently contracted to build a critical lift crane. We produced a customized 25 Ton Top Running Double Girder Crane, which was installed at the Kennedy Space Center and used to build the Orion spacecraft.
This crane was not only a critical lift crane, but it was also a clean room crane.
A clean room is a manufacturing environment that, because of product requirements, must be kept as free from environmental pollutants as possible. Industries that commonly have clean room requirements include the electronics, food, beverage, pharmaceutical, and, as was the case with the Orion spacecraft, aerospace industries.
The food, beverage, and pharmaceutical industries produce products that are ingested by humans, so those products must be contaminate-free. Products produced in the electronics and aerospace industries are sensitive and could fail if exposed to contamination during production.
Because freedom from contamination is so important to the products developed in clean rooms, all equipment introduced into clean rooms — including critical lift cranes — must comply with strict clean room standards.
American Crane’s Clean Room Features
To meet NASA’s stringent clean room standards, American Crane designed their critical lift crane with these special features:
All fasteners are stainless steel and self-locking to ensure that no bolts or debris fall from the crane
The walkways are equipped with continuous kick plates to capture any dirt or debris
Stainless steel diamond-shaped track is used with the festoons to eliminate places that debris could gather
The runway conductor bars are covered in extruded plastic to prevent debris from escaping
There is a debris shield underneath the lower block to prevent any wire rope debris from reaching components of the Orion spacecraft
All electrical enclosures are shielded to ensure that no RFI or EMI reach the spacecraft
All axes of movement have extremely slow speeds, less than two inches per minute, to allow for the successful mating of critical components without risk of collision or damage
The crane control system utilizes a “watchdog” PLC system that checks each movement against what the operator commanded and stops erroneous motion.
For more information about American Crane and how we can custom build cranes that meet your clean room requirements, contact us today.
When you have an aerospace critical lift that could impact your project or the environment, it’s doubly important to follow all the proper procedures for safety and compliance. Many people are unsure of the exact legal requirements and the best way to ensure compliance. Here is a brief rundown on managing critical aerospace lifts.
If loss of control over the lifted item could invoke a declaration of a site emergency per the governing regulations such as NASA-STD- 8719.9.
If the item to be lifted is vital to the project schedule or irreplaceable.
If the item is lost during the lift, the resulting impact on cost or schedule might jeopardize program commitments.
If the lift occurs in close proximity to items that fit any of the definitions in items 1 through 3.
If the load exceeds 80 percent of the crane’s capacity, it is critical. If two cranes are used and the lift weight exceeds 75 percent of the rated capacity of one of the cranes, it is also considered critical.
Aerospace Critical Lift Requirements
If your planned lift fits into any of these categories, you are required to take certain safety precautions. The precautions may vary depending on the characteristics of the lift, but almost every aerospace critical lift will require specific safety precautions.
This person is responsible for ensuring that every member of the lift team understands their role and has the proper training. The Lift Supervisor must also confirm that the equipment has been properly inspected and has the right safety ratings to safely carry out the lift plan.
The Safety Representative cannot be the same individual as the Lift Supervisor. The Safety Representative is responsible for reviewing and checking all inspections, the lift plan, and must be on site during the lift to monitor the process and ensure adherence to the plan.
Critical Lift Plan
The Critical Lift Plan includes both a Hazard Report and a Lift Procedure. The entire team, but especially the Lift Supervisor and the Safety Representative should be familiar with the details of the plan.
Safety Review Meeting
Before undertaking the lift, the team must hold a Safety Review Meeting to ensure that all team members have a firm grasp on their roles and all lift procedures. The meeting can be held up to two weeks prior to the lift for very complex lifts, but two to three days is more common.
For aerospace critical lifts, you must use equipment rated to handle the necessary load plus a margin of error. The equipment must meet these requirements whether it is leased or owned and must meet minimum load rating for every item used in the lift, including rigging, jigs, cables and hoists.
American Crane Aerospace Equipment is designed to meet the requirements of aerospace critical lifts. American Crane Critical Lift Cranes are designed for durability, reliability and safeguarding equipment during lifts and to comply with appropriate industry guidelines. With over 40 years of experience designing and building the industry’s most respected cranes, American Crane products offer custom design and fabrication and a complete in-house quality assurance program to comply with standards. Before shipment, all cranes are completely tested and fully assembled to meet CMAA duty cycle requirements.
You must have certificates of inspection and original rating certificates for all equipment. These should be part of the Lift Plan and reviewed and validated in the Safety Meetings.
If you are responsible for managing a project or program that may include an aerospace critical lift, consider working with the experienced team at American Crane. Our team of experts provide high quality equipment, safety and reliability in every aerospace critical lift.
